1.2 System Description
The Titan II is a high-velocity, spatially correspondent manipulator system designed for remote manipulation tasks. The slave arm has six degrees of freedom
plus jaw open/close. When the operator moves the master arm, the slave arm duplicates the master arm movements, thus maintaining spatial correspondence between the master arm and slave arm.
The Titan II manipulator system is composed of the following parts (shown in
Figure 1-1):
•
The hydraulically powered slave arm, which uses a jaw tool to manipulate
objects.
•
The slave controller, which distributes power to slave arm electrical assemblies, and processes signals going to and from the master controller and
slave arm.
•
The master controller. This assembly contains:
-
The master arm, which the operator uses to interactively position the slave
arm.

major system units.
•
Functional descriptions of the master controller, slave controller, and junction box.
For descriptions of major slave arm assemblies and an overview of slave arm hydraulic and electrical systems, see the Titan II Slave Arm Supplement.
2.1 System Overview
The Titan II is a high-velocity, spatially correspondent remote manipulator system. The system is composed of the following parts (illustrated in Chapter 1):
•
The hydraulically powered slave arm, which uses a jaw tool to manipulate
objects.
•
The slave controller, which distributes power to the slave arm, and processes signals going to and from the master controller and slave arm.
•
The master controller. This assembly contains:
-
The master arm, which the operator uses to interactively position the slave
arm.
-
An LCD screen flanked by function keys. The operator uses the keys to
select operating options, and the screen to view system information.
-
Electronics assemblies that process signals going to and from the master arm
and slave controller.
•
A junction box that connects to the user’s electrical power source. The connection between the master controller and slave controller is also made
through the junction box .
•
Cables and hoses that connect system components.
Sensors in the Titan II slave arm and master arm provide information on the position of all slave arm and master arm segments. The slave arm may be optionally
equipped with force transducers whose signals can be processed by a user-supplied host computer to provide data on forces and torques in the slave arm.
To move or otherwise affect the slave arm, the operator moves the master arm or
enters commands on the master controller keyboard. Operator inputs to the mas-
011-0060, Version 1
2-1
2.2 Force and Position Sensing
Functional Description
ter arm and the keyboard are processed by the master controller into signals that
are sent to the slave controller. The slave controller processes the signals into
commands that are transmitted to the slave arm. These signals either (1) activate
servo valves in the slave arm to actuate slave arm movement, or (2) drive a solenoid valve that enables and disables slave arm hydraulics.
2.2 Force and Position Sensing
In the Titan II manipulator system, telemetry data (consisting primarily of data
on the position of slave arm and master arm joints) must be passed rapidly between system components. Telemetry serial data links connect the master controller and slave controller. These links use the RS-422 transmission protocol,
with transmissions taking place at 19.2 Kbaud.
Telemetry information is gathered from sensors in the slave arm and master arm
as described in Section 2.2.1 and 2.2.2.
2.2.1 Slave Arm Position Sensing
Each slave arm joint (except the jaws) contains a resolver that senses joint position.
Each resolver is made up of an outer stationary ring (the stator) and an inner rotating ring (the rotor). As the joint moves, the angle of the rotor changes relative to
the stator. The resolver has two electrical outputs that change as a function of the
sine and cosine of the rotor angle.
Slave arm resolver outputs are communicated to the slave controller, where they
are converted into digital position data for the joint. All resolver outputs are used
in the system control loop.
Slave arm jaw position is sensed by an LVDT in the wrist/jaw assembly.
2.2.2 Master Arm Position Sensing
Each master arm joint contains a potentiometer assembly that senses joint position.
Each potentiometer assembly contains a variable resistor (the potentiometer element) and a sliding contact (the potentiometer wiper). As the joint rotates, the
wiper moves along the element. Since voltage of the wiper output signal is a
function of the wiper’s position along the element, this signal can be used to determine how far and in what direction the joint has moved.
Potentiometer outputs are communicated to the master controller, where they are
converted into digital position data for each joint. All potentiometer outputs are
used to input position commands to the system control loop.
The jaw bands do not contain any position-sensing mechanism.
2.2.3 Force/Torque Sensing
The slave arm may be optionally equipped with a force/torque sensor and two
jaw force pressure transducers.
2-2
011-0060, Version 1
Functional Description
2.3 Manipulator System Control Loop
The force/torque sensor is located in the wrist. It is composed of four rings, each
containing two strain gauge bridges. These strain gauges allow the system to
sense forces in the x, y, and z directions (referenced to the wrist), and to sense
torque about the x, y, and z axes. A preamplifier board in the center of the
force/torque sensor converts the microvolt-level outputs of the strain gauge
bridges to volt-level signals. These signals can be processed by a user-provided
computer into data on the force and torque being applied to individual slave arm
joints.
Two optional pressure transducers in the slave upper arm measure pressure in the
two jaw hydraulic hoses. Signals from these pressure transducers can be processed by a user-supplied computer into data on the force being applied to jaw surfaces.
Signals from the force/torque sensor and the jaw pressure transducers are carried
through the slave arm by the wiring harness. The signals exit from the slave arm
at the shoulder through the bilateral electronics cable. The user can then access
and process the force signals with user-supplied equipment.
Slave arm force/torque data is not used in the Titan II system control loop.
2.3 Manipulator System Control Loop
The Titan II control system operates by simultaneously receiving operator inputs
through the keyboard, gathering data from sensors in the slave arm and master
arm, processing system data, and outputting information required to make all system components function.
The manipulator system responds to operator input made either through the master arm or through software.
The operator makes inputs through the master arm by moving master arm joints,
pressing the master arm freeze button (to freeze the slave arm in its current position), and squeezing the master arm jaw bands (to open and close the jaws).
When the operator moves the master arm, potentiometers in the master arm send
signals to the master controller. The master controller processes these signals
into digital position data for master arm joints, which it then sends to the slave
controller. At the same time, the slave controller is gathering data from slave
arm resolvers, and processing this information into digital slave arm joint position data. The slave controller then compares master arm and slave arm position
data. If the master arm and slave arm positions are not the same, the slave controller sends current to appropriate servo valves in the slave forearm, resulting in
the release of hydraulic fluid to selected slave arm actuators. This drives the
slave arm into correspondence with the master arm.
The operator also affects the slave arm by issuing software commands (that is,
pressing master controller keys). For example, a preprogrammed slave arm
movement such as the stow sequence is performed when the control system commands the slave arm to move based on position information stored in the master
controller’s memory.
011-0060, Version 1
2-3
2.4 Master Controller
Functional Description
The master controller and slave controller are programmed to detect certain system error conditions. These error conditions may prevent the enabling of hydraulics upon system startup, or automatically disable slave arm hydraulics during
operation.
Information generated by the master controller and slave controller is used to update the user interface. For example, a master values screen displays the current
position of each master arm joint and the current state of master controller function keys. The slave values screen shows the commanded and actual positions of
each slave arm joint.
2.4 Master Controller
The master controller is composed of the master arm, the faceplate assembly, and
controller electronics. An electrical on/off switch on the faceplate assembly controls power to the master controller.
The master controller is connected to the user’s electrical power and the slave
controller through the junction box, as shown in Figure 1-1.
See Chapter 6 for exploded drawings of the master controller and the faceplate assembly.
2.4.1 Master Arm
The master arm is mounted on the master controller faceplate. The master arm is
a small kinematic replica of the slave arm, and has the same relative range of motion. The operator moves the master arm with the wrist and fingers.
Potentiometers in master arm joints are used as position transducers. Potentiometer signals are routed through the master arm base to master controller electronics
assemblies, where the signals are converted, processed, and used in the system
control loop.
The master arm has the following functional controls (shown in Figure 4-2):
•
Master arm joints. The operator moves these joints to actuate movement of
the corresponding slave arm joints.
•
Freeze button. Pressing the freeze button freezes the slave arm in its current
position.
•
Wrist collar. The operator rotates the wrist collar to rotate the slave arm
wrist.
•
Jaw bands. The operator presses the forward jaw band to close the slave
arm jaws, and the aft jaw band to open them.
See Chapter 4, Operations, for detailed information on using these master arm
controls.
See Section 2.3 for information on how master arm position information is used
in the system control loop.

Operation
4.1 Introduction
For operational purposes, the TITAN system can be viewed as two components:
the master controller with the master arm, and the slave controller with the slave
arm.
The master controller contains a master arm, function keys, and display screen.
The operator controls all system functions from the master controller.
The operator controls electrical power to the master controller by an on/off
switch on the front panel, and performs system functions by pressing keys to select menu options displayed on the screen. The screen also displays system
status information.
The operator observes the slave arm directly or through a video system, and controls the slave arm by moving the master arm and observing the slave arm’s response. The slave arm mimics the movement of the master arm.
4.2 Controls and Display Menus
The operator controls the slave arm from the master controller. The master controller, shown in Figure 4-1, contains the following components:

4.2.1 Master Arm
The master arm (Figure 4-2) is a miniature replica of the slave arm, with the
same relative range of motion. Each slave arm joint or function has a kinematic
analog in the master arm.
Figure 4-2 Master Arm Controls
The small size of the master arm allows the operator to easily control all functions with the wrist and fingers. These functions include:
•
Slave arm joint movement. The operator moves a master arm joint to move
the corresponding slave arm joint.
•
Slave arm freeze. Pressing the button on the end of the master arm freezes
the slave arm in its current position.
•
Wrist rotate. The operator rotates the wrist by rotating the master arm wrist
collar.

4.7.2 Freezing Individual Joints
The operator can freeze individual slave arm joints by using the FREEZE menu.
From the OPERATE menu, select 1>FREEZE to call up the FREEZE menu (Figure 4-10). The FREEZE menu lets the operator freeze individual joints shown
on the menu (azimuth, shoulder, elbow, pitch, yaw, and wrist). Freezing individual joints is useful for tasks where only some joints are required to move. The
operator can provide a stable platform for the task by freezing the remaining
joints.
Figure 4-10 FREEZE Menu
On the FREEZE menu, current status of each joint is indicated by FRZ (frozen)
or REIN (reindexed, or unfrozen). The key next to each joint toggles that joint
between FRZ and REIN. The slave arm must be frozen before the operator can
use the FREEZE menu to freeze or unfreeze individual joints.
To unfreeze all joints, select 7>REIN ALL.
To exit from the menu, select 8>EXIT.
After the operator selects the FREEZE/REINDEX functions for each joint, and
unfreezes the slave arm, the operator can move only those joints in the REINDEX mode.

4.8 Controlling Wrist Rotation
Operation
WARNING
If the slave arm is frozen and unfrozen while slave arm hydraulics
are disabled, the commanded slave arm position may change while
hydraulics are disabled. When hydraulics are re-enabled, the slave
arm may suddenly move to the new commanded position.
4.7.3 Changing Slave Arm and Master Arm Position Correspondence
Transparent reindexing allows the master arm to be repositioned without producing corresponding movements in the slave arm. This function is useful when a
manipulative task results in an awkward position for the master arm. The slave
arm can be frozen while the operator repositions the master arm for more comfortable operation. When it is unfrozen, the slave arm will not return to correspondence with the master arm. Instead, it will respond normally to master
inputs, but with the offsets introduced while the slave arm was frozen.
4.8 Controlling Wrist Rotation
The wrist has the following two modes of operation:
POSITION MODE. In position mode, the operator rotates the wrist collar in the
direction and to the degree of desired slave arm wrist rotation.
RATE MODE. Rate mode allows the slave arm wrist to rotate continuously. Rotating the master collar in either direction from a null position starts the manipulator wrist rotating in the corresponding direction. The rate of rotation is
proportional to the degree of rotation of the master collar from null position.
The operator can change the current wrist mode from the OPERATE menu by
pressing 5>WRIST MD. The slave arm must be unfrozen to change wrist mode.
When you switch between rate and position modes, a feature of the control system prevents sudden rotation of the slave arm wrist. When the operator switches
from position to rate mode, the wrist freezes in its current position. The operator
must move the master arm collar to the null position before the wrist will begin
to rotate under rate control. When switching from rate to position mode, the
wrist slowly returns to correspondence with the master arm collar. When it
reaches correspondence, the wrist is again slaved to the master arm wrist collar
position.
4.9 Jaw Operation
4.9.1 Controlling Jaw Opening and Closing
The jaws can operate in the following modes:
POSITION. In position mode, the jaws open and close incrementally as the operator squeezes the forward and aft jaw bands. Squeezing the forward jaw band
causes the jaw to close until the band is released. Squeezing the aft jaw band
causes the jaw to open until the band is released.
4-10
011-0060, Version 5
Operation
4.10 Controlling Slave Arm Speed
TOGGLE. In toggle mode, the only possible jaw positions are completely open
or completely closed. Squeezing the forward jaw band toggles the jaw state between fully closed and fully opened.
LOCK. In lock mode, the jaw freezes in its current position until the operator selects another mode.
The operator changes the current jaw mode from the OPERATE menu by pressing 6>JAW MD. This key toggles between position, toggle, and lock modes.
The slave arm must be unfrozen to change jaw mode.
4.9.2 Controlling Jaw Speed
When the jaw is in position mode, the operator can control the speed of jaw
movement with the Jaw Speed function. To use this function, follow these steps:
1.
From the MAIN menu, select 2>OPTIONS.
2.
On the OPTIONS menu (Figure 4-11), a number next to 2>JAW SPEED
shows the current jaw speed. Press 2>JAW SPEED to increment this
number by 4. The higher the number, the greater the jaw speed.
Possible jaw speeds range from 04 to 32. Each time that you start up the manipulator system, the jaw speed value defaults to 16.
Figure 4-11 OPTIONS Menu
4.10
Controlling Slave Arm Speed
In general, the speed of master arm movement controls the speed of slave arm
movement. However, you can also select a fast mode or slow mode to regulate
slave arm speed.
Fast mode is the full-speed mode at which the slave arm normally operates.
Slow mode is intended for use when personnel are near the slave arm and could
inadvertently enter its operating envelope.
To use the DYNAMICS function to change slave arm speed, follow these steps:
1.
From the MAIN menu, select 2>OPTIONS.

4.11 Scaling Slave Arm Movement
2.
Operation
From the OPTIONS menu (Figure 4-11), select 1>DYNAMICS. This key toggles the slave arm between fast and slow modes.
4.11
Scaling Slave Arm Movement
The Titan manipulator system lets you alter the scale of master arm movement to
slave arm movement to produce different degrees of slave arm control. Joints affected by scaling are the azimuth, shoulder, elbow, pitch, and yaw.
The default setting for this scale is 100%, which produces a one-to-one correspondence between master arm and slave arm movement. (For example, moving
the master arm elbow joint through 50 degrees of its range causes the slave arm
elbow joint to move through 50 degrees of its range.) Changing the scale to a
percentage less than 100% reduces slave arm movement to that percentage of
master arm movement, allowing finer slave arm control. The Titan system offers
position scaling in increments of 10% from 10% to 100%.
The operator can view the current scaling value in the OPTIONS menu (Figure 411), and can change that value using 3>SCALE SEL.
To change the position scaling value, follow these steps:
1.
Display the OPTIONS menu.
2.
A number next to the 3>SCALE SEL option shows the current position scaling
value. To change to another value, press 3>SCALE SEL; the number will
be incremented by 10%. (When the number reaches 100%, pressing
3>SCALE SEL again returns the value to 10%.)
3.
When the displayed percentage is correct, press 8>EXIT to return to the OPERATE menu.
Upon system startup, the Scale Sel number defaults to the most recent value.
Once you have set the desired scaling percentage, you can use an option on the
OPERATE menu to switch back and forth between that percentage and 100%.
To toggle between the two percentages, follow these steps:
1.
Display the OPERATE menu (Figure 4-9).
2.
A number next to the 3>SCALE TOG option shows either 100% or the current
position scaling value (previously set in the OPTIONS menu). To toggle to
the other percentage, press 3>SCALE TOG. (For example, if the operator
previously set the scaling percentage to 60%, pressing the 3>SCALE TOG
key will toggle scaling between 60% and 100%.)
The Scale Tog value defaults to 100% upon system startup.
4.12
Setup Functions
The SETUP menu (Figure 4-12) is used to set slave arm movement limits, program the stow sequence, change screen display characteristics, set security levels

Setting Servo Valve Voltage Offsets
Slave arm actuators move in response to changes in the voltage sent by the slave
controller to the servo valves that provide hydraulic fluid to the actuators. Since
4-18
011-0060, Version 5
Operation
4.17 Setting Servo Valve Voltage Offsets
individual servo valves vary in their responses to a given voltage, and since environmental operating conditions can affect servo valve response, you may need to
provide voltage offsets so that voltages sent to the servo valves elicit the proper
slave arm responses.
Once voltage offsets have been set for the servo valves, you normally do not
need to change the offsets unless you replace a servo valve.
To set servo valve offsets, follow these steps:
1.
Start up the manipulator system.
2.
Be sure that hydraulic power is turned on at the hydraulic power unit.
3.
Go to the OPERATE menu, and press 6>JAW MD until the jaw mode indicator reads “POS” (for POSITION mode). Press 5>WRS MD until the wrist
mode indicator also reads “POS.”

1>EDIT notation. To edit in decimal notation, use the RT key to bypass the fourdigit hexadecimal entry location, and edit the five-digit decimal entry location in
parentheses ( - 0 0 0 0 0 ). The cursor indicates which numeral is currently selected for editing. Move the cursor to the right or left using the RT or LF key until the cursor appears below the desired number. Increment or decrement the
numeral at the cursor location by using the UP or DN keys respectively.
Save the edited word by pressing 1>EDIT again. The changed word will appear
next to the displayed address, and the cursor will move back to the first numeral
of the memory address.
The displayed memory word is normally read and displayed only when the operator enters the MEMORY EDIT menu, when the address is changed, or when a
memory word is changed. This word can be continuously displayed (and updated as it changes) if the 2>VIEW function is set to ON. (Press 2>VIEW to toggle the View function between ON and OFF.) If the View function is ON, the
memory address and data word will appear in all menus at the same screen location. The operator can remove the address and word display by entering the
MEMORY EDIT menu and setting 2>VIEW to OFF.

Operation
See the troubleshooting chapter for information about possible specific causes of
fatal errors.
4.20
Enabling/Disabling Slave Arm Hydraulics
The hydraulic isolation valve in the slave upper arm is either open (enabling hydraulic fluid to flow to slave arm actuators), or closed (preventing slave arm
movement). In this manual, opening the hydraulic isolation valve is called enabling slave arm hydraulics, while closing the valve is called disabling slave arm
hydraulics.
As described in Section 4.5, you must enable slave arm hydraulics as part of the
startup process before you can operate the slave arm. Once you have enabled
slave arm hydraulics, you can disable them at any time by pressing the UP control key. Also, some system errors automatically disable hydraulics.
Once slave arm hydraulics have been disabled, you must use the DRIVERS
menu to enable them. To re-enable slave arm hydraulics, follow these steps:
1.
From the OPERATE menu, select 2>DRIVERS to display the DRIVERS
menu (Figure 4-27).
Figure 4-27 DRIVERS Menu

The current state of the hydraulic isolation valve is displayed next to 6>HYDR.
“On” means that slave arm hydraulics are enabled, and “off” means that
they are disabled. To switch between enabled and disabled states, press
6>HYDR.
If you need to disable slave arm hydraulics, be sure to freeze the slave arm first.
Then be sure to re-enable slave arm hydraulics before you unfreeze the slave arm.
The DRIVERS menu also contains access for up to five additional solenoid valve
channels that can be accessed through the slave controller.

5.3 Fault Isolation Aids
Troubleshooting
If the problem remains, use the troubleshooting tables in this chapter to isolate
the fault.
5.3 Fault Isolation Aids
This section explains how to use master controller screen displays to aid in isolating a fault or confirming a fault diagnosis. This section also explains how to use
simple diagnostic procedures to isolate a joint fault to the slave arm or master
arm.
5.3.1 Isolating Joint Faults
An erratic or unresponsive slave arm joint may be caused by a failure in the corresponding master arm joint. If a single joint on the slave arm appears to have
failed, try to stow or deploy the slave arm. If the unresponsive slave arm joint
moves properly in the stow/deploy sequence, the fault is probably in the corresponding master arm joint.
You can also use the master arm data display and the slave arm data display (described in Chapter 4, Operations) to diagnose joint problems. These displays provide information on the position of each moveable master arm and slave arm part.
For both data displays, if a joint is not moving, the position value should not
change. If the slave arm is frozen, a changing position value for a joint probably
indicates a failure in a master arm potentiometer, a slave arm resolver, electrical
cables, or a printed circuit board in the master or slave controller.
Displaying the master arm data screen automatically freezes the slave arm, but
displaying the slave arm data screen does not. If you are diagnosing a slave arm
joint problem, first freeze the slave arm and display the slave arm screen. After
you have observed whether any position values are changing, you can unfreeze
and operate the slave arm to observe the effect of operation on slave arm position
values.
If you use the master arm or slave arm data display to diagnose a joint problem,
use Table 5-2, Screen Symptoms, to determine possible causes.
5.3.2 Diagnosing Master Arm Joint Failures
The master screen (Figure 4-24) displays position values for each joint and for
the jaw bands. A value of “0” indicates that the joint is at the approximate midpoint of its range of motion. Positive values indicate movement either up or to
the right; negative numbers indicate movement down or to the left.
If a joint is not moving, the position value should not change. A changing position value for an immobile joint probably indicates a failure in a master arm potentiometer or a master controller printed circuit board.
You can operate the master arm while the master data screen is displayed to test
master arm sensors. Displaying the master data screen automatically freezes the
slave arm, so moving the master arm will not move the slave arm.

011-0060, Version 5
Troubleshooting
5.3 Fault Isolation Aids
5.3.3 Diagnosing Master Controller Key and Freeze Button Failures
Information in the master arm data display (described in Chapter 4, Operations)
allows you to diagnose problems with master controller keys or the freeze button.
The status of each key and the freeze button is shown at the bottom of the display
(see Figure 4-24). Each character on the display corresponds to a key or to the
freeze button. If the key or button is operating correctly, the character for that
key or button will be “0” when it is not being pressed and “1” when it is pressed.
If a failure has occurred, the display will show either “0” or “1” both when the
key is pressed and when it is not. The location of each key on the display is
shown in Figure 5-1.
Figure 5-1 Function Key Map, Master Controller Screen
(Numbered from Left to Right)
5.3.4 Diagnosing Slave Arm Joint Failures
The slave values screen (Figure 4-25) displays slave arm position values. The
command values are the commanded position values that are transmitted to the
slave controller from the master controller. The position values are the actual
joint position values sensed at each slave arm joint.
A value of “0” indicates that the joint is at the approximate midpoint of its range
of motion. Positive values indicate movement either up, to the right, or clockwise; negative numbers indicate movement down, to the left, or counterclockwise.
If a joint is not moving, the position value should not change. If the slave arm is
frozen, a changing position value for a joint probably indicates a failure in a
slave arm resolver or a slave controller printed circuit board.
While the slave values screen is displayed, the operator can unfreeze and operate
the slave arm to aid the diagnosis. Slave arm operation will be less stable in this
menu than during normal operation, since the position update rate has been reduced to allow the reading of the slave arm data.
If you suspect that a slave arm joint is malfunctioning, you can also use the slave
values screen and the information in Table 5-1 to check the joint. Table 5-1
shows a range of values for each slave arm joint when the joint is at its hardware
011-0060, Version 5

limit. In this table, positive numbers indicate the right, upward, or clockwise
joint limit. Negative numbers indicate the left, downward, or counterclockwise
joint limit. For the jaws, the lower value indicates the completely closed position, and the higher limit indicates the completely open position. The table does
not list values for the wrist, since the wrist rotates continuously and has no hardware limits.
If you suspect that a slave arm joint has malfunctioned, move the joint to either
its positive or negative hardware limit. Then compare the position value for that
joint on the slave values screen with the corresponding numbers in Table 5-1. If
the screen value falls outside the range of table values, check the appropriate portion of Table 5-2 for possible problem causes.

Troubleshooting tables are organized by major functional units. These units and
assemblies are:
Master controller screen
Master arm
Entire slave arm
Slave arm joints
Jaw
Additional tables explain how to diagnose and troubleshoot system errors and fatal telemetry errors.
Since all major manipulator system units are interactive, the unit that displays a
symptom may not be the one that requires repair. To isolate a fault, go to the table for the unit or assembly that displays the symptom or alerts you to the problem. (For example, if you are alerted to a slave arm problem by the master arm
data screen, see the screen troubleshooting table.)
The troubleshooting table will list at least one possible cause for each symptom.
If there are multiple possible causes, they are listed in the order of likelihood of
occurrence. Perform corrective maintenance to remedy each possible cause until
you have eliminated the fault.
There is no troubleshooting table for master controller or slave controller electronics, since failure of these electronics assemblies is manifested in the slave
arm, as a system error, or as a fatal telemetry error.

5.4.6 System Errors
A system error occurs when the system detects communication problems or apparent anomalies in the position or speed of the master arm or slave arm. System
errors can be caused by malfunctions in the slave arm, master arm, master controller, or slave controller. System errors can also be caused by faulty cable connections between any of these units.
The operator is alerted to system errors in two different ways. If a system error
is detected upon system startup, the Startup with System Errors screen appears.
If a system error is detected during operation, the operator is alerted by the ERR
flag at the top of the screen.
The operator can disable system error checking for any of the system errors, as
described in Chapter 4, Operations. If an error check has been disabled, errors in
that category will not be flagged on the screen.
After you have used the SHOW ERRORS menu to identify the error category,
use the table below to isolate the fault.
Table 5-7 System Error Descriptions

6.4.3 Replacing the Submersible Slave Controller PROM
In the procedures for replacing the submersible slave controller PROM, item
numbers in parentheses refer to parts in Figure 6-4.
6.4.3.1 Removing the Submersible Slave Controller PROM
1.
Perform steps 1 through 6 in Section 6.4.1.1 on removing slave controller PC
boards.
2.
Remove the standoff (15) that is closest to the connector on top of the optical
isolation board (5). Rotate the optical isolation board on the other standoff
(15) until the PROM on the CPU board (4) is exposed. You should not need
to disconnect the cable from the connector on top of the optical isolation
board to rotate the board.
3.
Eject the PROM from its socket on the CPU board (4).
6.4.3.2 Installing the Submersible Slave Controller PROM
CAUTION
When you install the PROM chip, make sure that the small notch on the
edge of the chip is toward the edge of the CPU board. Installing the chip
in the wrong orientation will damage system electronic assemblies.
1.
Install the new PROM into its socket on the CPU board (4). When you install
the PROM chip, make sure that the small notch on the edge of the chip is towards the edge of the CPU board.
2.
Continue by reversing the instructions for removing the slave controller PROM
in Section 6.4.3.1. Also follow the instructions below.
Lubricate the o-rings (19 and 53) with waterproof grease or Aqua LubeTM before
you install them.
Torque the screws (23) that attach the bottle mount (25) to 10 ft-lb. Also torque
the screws (22) that attach the cover plate (18) to 10 ft-lb.
After you have reassembled the slave controller, perform the vacuum test described in Section 6.4.4.
CAUTION
Do not submerse the slave controller until you have tested the assembly
for air leaks by performing the vacuum test.

6.4.4 Performing the Submersible Slave Controller Vacuum Test
After you have reassembled the submersible slave controller, test the assembly to
ensure that all seals are air tight. Item numbers in parentheses in the test procedure refer to parts in Figure 6-4.
To perform the vacuum test, follow these steps:
1.
Remove the hydraulic plug (54) from the slave controller lid (18).
2.
Screw a fitting (-4, straight thread) into the plug hole. Attach the other end of
the fitting to the hose of a vacuum pump with a gauge.
3.
Evacuate air from the slave controller. Wait for several minutes, and then
check the vacuum gauge to see if the pressure has remained constant (indicating that the slave controller is air tight) or has changed (indicating an air
leak in the assembly).
a.
If no air leaks into the slave controller, the controller is ready for submersion. Remove the vacuum pump hose and reinstall the hydraulic plug
(54) on the slave controller lid (18).
b.
If air leaks into the slave controller, check the two lid o-rings (19, 53), the
o-rings on the electrical connectors (7, 44, 64), and the sealing surfaces
of the fitting and hose for the vacuum pump. Then reassemble the
slave controller and repeat the vacuum test.

CHAPTER 1
GENERAL INFORMATION
This manual supplement describes the Titan II slave arm. For information on
the Titan II control system, and on how the slave arm is integrated into the manipulator control system, see the Titan II manipulator control system manual.
1.1 Slave Arm Orientation
Throughout this manual, the slave arm is described as if the operator is standing
behind the azimuth assembly looking toward the jaw with the arm straight out.
From this orientation, sides are referred to as left, right, top, and bottom. The azimuth end of the slave arm is called the base, and the jaw end is called the tip.

CHAPTER 2
FUNCTIONAL DESCRIPTION
This chapter contains functional descriptions of major slave arm assemblies and
an overview of slave arm hydraulic and electrical systems.
2.1 Slave Arm Overview
The slave arm is a servo-hydraulic manipulator with seven functions and six degrees of freedom. The slave arm’s seven functions (see Figure 2-1) are azimuth
yaw, shoulder pitch, elbow pitch, wrist pitch, wrist yaw, wrist rotate, and jaw
open/close.
Movement of each slave arm joint is actuated by a linear or rotary hydraulic actuator. The servo valves that control actuator movement are contained in the
slave arm.
The Titan II slave arm comes in two models: the unilateral model and bilateral
model. The unilateral slave arm is the standard or basic Titan II model. The bilateral slave arm contains all features of the unilateral model, but also contains a
force/torque sensor and two jaw force pressure transducers. If your manipulator
system contains a bilateral slave arm, the Titan II manipulator control system
manual will describe how the force/torque sensor and jaw force pressure
transducers work in your system.
The upper arm segment contains a hydraulic fluid filter, a solenoid valve that is
used to enable and disable slave arm hydraulic power, a pressure transducer that
monitors hydraulic supply pressure, and electrical connections for slave arm electrical assemblies. In the bilateral slave arm, the upper arm contains two additional pressure transducers that measure force on jaw surfaces.
The forearm segment contains seven servo valves that supply slave arm hydraulic actuators, and a lock valve that prevents the shoulder joint from sagging when
hydraulic pressure to the slave arm is disabled.
The unilateral Titan II slave arm has one electrical connection to the control system (called the unilateral cable). This cable carries power and signals to and
from all standard slave arm electronics assemblies. The bilateral slave arm
model also connects to the control system through the unilateral cable, but it contains an additional cable (called the bilateral cable) that carries power and signals
to and from the force/torque sensor and jaw force pressure transducers.
Slave arm hydraulic connections consist of a supply hose and return hose that are
attached to the user’s hydraulic power unit. These hoses connect to the slave upper arm.

Functional Description
2.1 Slave Arm Overview
2.1.1 Slave Arm Component Overview
The slave arm’s mechanical assemblies provide a skeleton for the hydraulic actuators that cause slave arm movement. This skeleton has the following major
components (Figure 2-2):
•
Azimuth. Attaches the slave arm to the user’s mounting platform. Contains
a hydraulic rotary vane actuator that swings the slave arm horizontally in a
partial circle.
•
Shoulder. This joint is formed by the connection of the azimuth and the upper arm. A linear actuator pinned between the azimuth and upper arm
causes the shoulder joint to pivot, moving the upper arm up and down.
•
Upper arm. Contains hydraulic and electrical connections, the hydraulic
supply fluid filter, the solenoid valve that enables and disables slave arm
movement, and the hydraulic supply fluid pressure transducer. In the bilateral slave arm model, there are two additional pressure transducers that
measure jaw pressure.
•
Elbow. Contains a rotary vane actuator that rotates the forearm up and
down relative to the upper arm.
•
Forearm. Contains servo valves that supply slave arm actuators, and a lock
valve for the shoulder actuator.
•
Pitch/yaw assembly. Made up of two assemblies, the pitch and the yaw,
containing identical hydraulic rotary vane actuators. These actuators are
mounted at 90° to each other. The pitch actuator actuates up and down
movement; the yaw actuates left and right movement.
•
Wrist/jaw assembly. Contains a hydraulic rotary vane motor, and can rotate
continuously (360°) in either direction. Parallel-acting jaws are opened and
closed by a hydraulic linear actuator. The bilateral slave arm wrist contains
a force/torque sensor which can be used to calculate the forces and torques
for all slave arm joints.
2.1.2 Slave Arm Hydraulic System Overview
The slave arm contains two hydraulic systems: the motive hydraulic system that
powers slave arm actuators, and the wireway compensation system that provides
pressure compensation for slave arm wireways.
2.1.2.1 Motive Hydraulic System
The slave arm is connected to the user’s hydraulic power unit by a supply line
and a return line. The supply line enters the slave arm at the base of the upper
arm. Fluid from the supply line passes through a filter that helps protect the arm
from contaminants that may have been introduced through the user’s hydraulic
fluid. The supply fluid then flows through a operator-controlled solenoid valve
that enables and disables slave arm hydraulics.
The supply fluid runs through an output flange on the right side of the upper arm
into the elbow slip ring. The slip ring communicates the fluid to a output flange
011-0061, Version 1

011-0061, Version 1
Functional Description
2.1 Slave Arm Overview
on the left side of the forearm. In the forearm, fluid is distributed to the seven
servo valves that control the following hydraulic actuators:
•
Azimuth rotary vane actuator
•
Shoulder linear actuator
•
Elbow rotary vane actuator
•
Pitch subassembly rotary vane actuator
•
Yaw subassembly rotary vane actuator
•
Wrist rotary motor
•
Jaw linear actuator
Fluid for the azimuth and shoulder actuators is routed backward through the elbow slip ring. Fluid for the elbow and pitch actuators is ported directly from the
forearm. Fluid for the yaw, wrist, and jaw actuators is routed forward from the
forearm through an output flange on the right side of the pitch subassembly. This
fluid passes through slip rings in the pitch and yaw subassemblies and through an
output flange in the top side of the yaw. From here fluid enters the wrist to
power the wrist motor and jaw linear actuator.
Hydraulic return generally reverses the path of hydraulic supply. All return fluid
is eventually collected in the junction box in the upper arm, which is connected
to the hydraulic power unit return line.
A schematic diagram of the slave arm motive hydraulic system can be found in a
plastic sleeve at the back of this manual.
2.1.2.2 Wireway Compensation Hydraulic System
The slave arm has a separate, passive hydraulic system that provides pressure
compensation for slave arm wireways when the slave arm is submerged in water.
The wireway compensation system prevents water from leaking into the wireways and also keeps wireway cables from being crushed when the slave arm is
submerged.
In terrestrial systems, wireway compensation is unnecessary and the wireway
compensation system is not filled with fluid.
In submersible systems, the wireway compensation system must be attached to a
wireway compensator. The compensator can be supplied by the factory or by the
user.
The factory-supplied wireway compensator, which is a cylinder containing a rolling diaphragm, attaches to any convenient surface near the slave arm that is no
higher than six feet above the azimuth. Ports on one end of the cylinder are open
to seawater. The other end of the compensator contains an overpressure relief
valve, a fill valve, and an input port valve.
Changes in pressure are accommodated by the diaphragm, which is held in place
with a spring-loaded piston. The relief valve provides backup pressure compensation by releasing wireway hydraulic fluid into surrounding seawater when pressure inside the wireways exceeds outside pressure by approximately 40 psi.
011-0061, Version 1
2-5
2.2 Slave Arm Assemblies
Functional Description
The wireway compensation system is filled by forcing high-pressure fluid
through the compensator fill valve. Fluid fills the accumulator cavity in the compensator, and flows through a hose to the wireway hydraulic port in the azimuth
base.
From the azimuth, the hydraulic fluid flows through all slave arm wireways. It
surrounds the wireways, going through the upper arm, elbow, forearm and wrist.
Its return path is through the center of the slip rings to a capped return (purge)
hose in the upper arm.
2.1.3 Slave Arm Electrical System Overview
Electrical lines in the slave arm carry power and telemetry information to individual electronics assemblies in various slave arm segments.
In the unilateral slave arm model, power and telemetry information is routed to
the slave arm from the control system through the unilateral electronics cable.
This cable carries power and signals to and from slave arm resolvers, servo
valves, the jaw LVDT, the supply line pressure transducer, and the solenoid
valve.
The bilateral slave arm model uses the unilateral electronics cable for the same
purposes as the unilateral slave arm. However, the bilateral slave arm also uses a
second cable (called the bilateral electronics cable) to carry power and signals to
and from the force/torque sensor in the wrist and the jaw pressure transducers in
the upper arm.
Both the bilateral and unilateral electronics cables enter the slave arm at the base
of the upper arm. These cables run through the upper arm and attach to connectors on the junction box at the tip of the upper arm.
The junction box serves as a junction for some slave arm electrical connections.
It also contains a pressure transducer that monitors hydraulic supply pressure. In
the bilateral system, the junction box contains two additional pressure
transducers to measure force on slave arm jaw surfaces.
The slave arm wireway has its primary electrical connection junctions in the upper arm and forearm. In the upper arm junction box, there are connections for
wires running to resolvers in the azimuth and shoulder. In the bilateral slave arm,
connections to two jaw pressure transducers are also contained in the upper arm
junction box.
The forearm contains electrical connections to the seven servo valves. It also
contains connectors for the wires that thread farther up into the arm to the pitch,
yaw, and wrist resolvers and to the jaw LVDT.
2.2 Slave Arm Assemblies
This section provides a functional description of each major slave arm assembly.
Figure 2-2 shows the location of each assembly.
2-6
011-0061, Version 1
Functional Description
2.2 Slave Arm Assemblies
2.2.1 Azimuth Assembly
The azimuth assembly forms the base of the slave arm. The bottom of the azimuth assembly mounts onto the user’s mounting platform.
The azimuth assembly contains a hydraulic rotary vane actuator that swings the
slave arm in a horizontal partial circle. The azimuth moves when hydraulic fluid
is directed into port C1 or C2 of the actuator from a servo valve in the forearm.
When hydraulic fluid is introduced through C1, the azimuth housing rotates
clockwise (as viewed from above). If the servo valve directs fluid into C2, the
azimuth housing moves counterclockwise. The slave arm is attached to the azimuth housing and moves with it.
Any internal fluid leakage from the azimuth is directed through a port in the azimuth lid. A hose from this port goes into the upper arm and connects to the junction box, where the fluid mingles with other system return fluid.
The azimuth position sensor is a resolver that lies directly beneath the azimuth
lid. A wire from the resolver goes from the azimuth into the upper arm, and connects to the general wireway at the upper arm junction box.
2.2.2 Linear Actuator Assembly
The upper arm segment is rotated about the shoulder by a linear actuator that is
pinned between the azimuth and upper arm.
The linear actuator moves when hydraulic fluid is directed into port C1 or C2 of
the linear actuator from a servo valve in the forearm. When hydraulic fluid is introduced through C1, the actuator piston extends. The arm pivots around the
shoulder joint, lifting the arm segment. When hydraulic fluid is directed through
C2, the piston retracts, pivoting the shoulder joint in the opposite direction and
lowering the arm segment.
2.2.3 Shoulder Joint
The shoulder joint connects the azimuth and the upper arm segment. The joint
contains a pivot assembly that allows the joint to rotate around a pivot pin. Joint
movement is driven by the linear hydraulic actuator that is pinned between the
azimuth and the upper arm.
The shoulder’s only electronic component is a resolver that senses shoulder position. A wire from the resolver goes from the shoulder into the upper arm, where
it connects to the general wireway at the upper arm junction box.
2.2.4 Upper Arm
The upper arm is the entry point into the slave arm for hydraulic supply and return lines, and for the electrical cables that connect to the slave controller. The
upper arm also contains:
•
A hydraulic fluid filter.
•
An operator-controlled solenoid valve that enables and disables slave arm
hydraulics.
011-0061, Version 1
2-7
2.2 Slave Arm Assemblies
Functional Description
•
A pressure transducer that monitors supply pressure. (The bilateral slave
arm model contains two additional pressure transducers that measure pressure on the lines to the jaw actuator.)
•
A junction box that connects wires from slave arm electronic assemblies.
2.2.4.1 Upper Arm Hydraulics
High-pressure hydraulic fluid entering the upper arm from the user’s hydraulic
power unit goes first to a filter and then to an operator-controlled solenoid valve.
The fluid then goes through the elbow to the forearm, where it is distributed to
servo valves that supply the seven slave arm actuators. Fluid that actuates shoulder and azimuth movement is routed backward through the shoulder to the upper
arm, from which it is distributed to the azimuth rotary actuator and the shoulder
linear actuator.
Return fluid from the slave arm is channeled through the arm to the junction box
in the upper arm. This fluid mingles with return fluid from the azimuth as described in Section 2.2.1. This system return fluid is directed to a hose that exits
from the slave arm at the base of the upper arm. This hose is attached to the return line of the user’s hydraulic power unit.
The solenoid valve in the upper arm enables and disables hydraulic flow to the
slave arm. When the solenoid valve is open, it connects user-supplied hydraulic
fluid to the slave arm supply line. When the solenoid valve is closed, it connects
the arm supply circuit to the slave arm return line, and blocks the user’s supply
line (as shown in the slave arm hydraulic schematic at the back of this manual).
2.2.4.2 Upper Arm Junction Box
Power and telemetry information are routed from the control system to the slave
arm through either one or two cables. In the unilateral slave arm model, the unilateral electronics cable carries power and signals to and from slave arm resolvers, servo valves, the hydraulic supply pressure transducer, and the solenoid
valve. The bilateral slave arm model contains the unilateral cable, but also contains the bilateral electronics cable, which carries power and signals to and from
the force/torque sensor in the wrist and the jaw pressure transducers in the upper
arm.
In the unilateral slave arm model, the unilateral cable enters the slave arm at the
base of the upper arm. This cable runs through the upper arm and attaches to a
connector on the junction box at the top of the upper arm. In the bilateral slave
arm model, both the bilateral and unilateral electronics cables enter the slave arm
at the base of the upper arm. These cables run through the upper arm and attach
to connectors on the upper arm junction box.
The junction box contains connections for all slave arm electrical components:
servo valves, resolvers, the jaw LVDT, the hydraulic supply pressure transducer,
and the upper arm solenoid valve. In the bilateral slave arm, the junction box
also contains connections for the force/torque sensor and the two additional pressure transducers.

011-0061, Version 1
Functional Description
2.2 Slave Arm Assemblies
2.2.5 Elbow Joint
The elbow, which is attached to the upper arm and forearm, contains a hydraulic
rotary vane actuator. The actuator housing is bolted to the forearm, so that the
forearm swings up and down as the actuator rotates.
The elbow actuator moves when hydraulic fluid is directed into port C1 or C2 of
the elbow actuator from a servo valve in the forearm. When the servo valve directs hydraulic fluid through C1, the forearm moves up; when fluid is introduced
into C2, the forearm moves down.
A slip ring in the elbow accommodates the rotation of the elbow relative to the
upper arm.
The slave arm wireway passes out of the upper arm junction box into the right
side of the elbow. The wires then run through the center of the elbow to the left
side, from which they enter the forearm.
Angular position of the elbow is sensed by a resolver in that joint.
2.2.6 Forearm
The forearm serves as the system’s hydraulic manifold. Primary features are:
•
A servo valve block containing seven servo valves.
•
A lock valve for hydraulic lines leading to the shoulder actuator.
•
Connectors for the pitch, yaw, wrist, and jaw position transducers.
Hydraulic fluid enters the forearm from the elbow, and is distributed to the seven
servo valves that control hydraulic flow to all slave arm actuators (azimuth,
shoulder, elbow, pitch, yaw, wrist, and jaws). From each servo valve, two lines
(C1 and C2) are routed to each hydraulic actuator.
A lock valve is located beneath the servo valve for the shoulder actuator. When
system pressure is not being applied, the lock valves close to prevent the shoulder joint from sagging.
In the forearm, wires leave the wireway to connect with the servo valves. Remaining wires exit from the left side of the forearm to the pitch/yaw assembly.
2.2.7 Pitch/Yaw Assembly
The pitch/yaw assembly is located between the forearm and the wrist/jaw assembly.
The pitch/yaw assembly contains two identical subassemblies, each containing a
rotary vane actuator, a hydraulic slip ring, and a resolver. These subassemblies
are called either the pitch or the yaw, depending on how they are mounted on the
slave arm. The pitch subassembly is attached to the forearm, the yaw subassembly is attached to the wrist, and a hydraulic manifold is located between the pitch
and yaw. The pitch subassembly moves the wrist up and down, and the yaw subassembly moves it left and right.
011-0061, Version 1
2-9
2.2 Slave Arm Assemblies
Functional Description
The hydraulic manifold between the pitch and yaw carries electrical lines and hydraulic fluid between the two subassemblies.
The pitch subassembly contains a rotary vane actuator with two hydraulic ports,
designated C1 and C2. Directing fluid into C1 causes the housing of the pitch actuator to move up; directing fluid to C2 causes the housing to move down.
The yaw subassembly is identical to the pitch assembly. The yaw subassembly is
turned 90° from the pitch assembly, and thus actuates left-to-right movement. Directing fluid into C1 causes the housing of the pitch actuator to move to the right,
and directing fluid to C2 causes the housing to move to the left.
A hydraulic slip ring in the pitch subassembly allows the pitch housing to remain
stationary relative to the forearm, and a hydraulic slip ring in the yaw subassembly allows the yaw housing to rotate relative to the pitch subassembly.
Angular positions of the pitch and yaw are sensed by a resolver in each subassembly.
2.2.8 Wrist/Jaw Assembly
The wrist/jaw assembly has two functions: the entire assembly rotates, and the
jaws open and close to let the operator grasp and manipulate objects.
The wrist base is attached to the yaw side of the pitch/yaw assembly. The wrist
can rotate continuously in either direction. Wrist rotation is performed by a hydraulic motor in the wrist/jaw assembly.
Hydraulic fluid flows to and from the wrist motor through a servo valve in the
forearm. The wrist motor has two hydraulic ports, designated C1 and C2. Directing fluid into C1 causes the wrist to turn clockwise; directing fluid to C2 causes
counterclockwise rotation.
The wrist contains a resolver to sense wrist position. Because the wrist can rotate continuously, the resolver rotor must also be able to rotate continuously, and
therefore cannot be attached to a wire. Instead, the wrist brushless resolver assembly contains a rotary transformer that communicates signals to and from the
resolver rotor.
In the bilateral slave arm, the wrist contains a force/torque sensor.
The jaws are at the tip of the wrist/jaw assembly. As the jaws open and close,
the gripping surfaces remain parallel.
The jaws are actuated by a hydraulic piston. The piston is controlled by fluid
flowing from the wrist through two hydraulic lines designated C1 and C2. When
the jaw servo valve in the forearm directs fluid into C1, the piston extends, causing the jaws to open. When fluid flows into C2, the piston retracts, causing the
jaws to close.
The force on the jaw surface (that is, the resistance of the object being gripped) is
a function of the pressure on the jaw hydraulic piston. In the bilateral slave arm,
this pressure is measured by two pressure transducers in the upper arm that are attached to jaw hydraulic lines C1 and C2.

CHAPTER 3
INSTALLATION
This chapter explains how to install the Titan II slave arm. For information
about installing and interconnecting elements of the Titan II control system, see
the Titan II manipulator control system manual.
CAUTION
Since the slave arm may not be rigid during the installation procedure,
support the slave arm at the elbow and the tip.
3.1 Preparing the Slave Arm Mounting Platform
The primary consideration for installation is the slave arm mounting location.
Determine an appropriate location from slave arm mounting details in this section and from the slave arm range-of-motion diagrams in Chapter 1. After you
have established the mounting location, prepare a mounting platform that will accommodate the slave arm mounting surface shown in Figure 3-1.
Figure 3-1 Slave Arm Mounting Surface
011-0061, Version 1
3-1
3.2 Slave Arm Installation
Installation
The attaching hardware for the slave arm consists of six 1/2-20 threaded stainless
steel hex-head cap screws. These screws attach the slave arm azimuth spindle to
the mounting platform. The screws must be long enough to thread through the
mounting platform and engage 0.5 inches into the azimuth.
Contact Schilling Development, Inc. for information about any special slave arm
installation considerations.
3.2 Slave Arm Installation
The slave arm may not be rigid during installation, so support the arm at the elbow and tip during the entire installation procedure.
1.
Move the slave arm next to the mounting platform. Orient the slave arm so that
it points in the correct direction.
2.
Carefully lower the azimuth onto the mounting platform. The bolt holes in the
azimuth bottom must be flush against the mounting platform.
3.
Lubricate the threads of the six mounting screws.
4.
Working from beneath the mounting platform, screw the six mounting screws
through the mounting platform bolt holes into the azimuth. The screws
must engage 0.5 inches into the azimuth. Torque the screws to 80 ft-lb.
3.3 Connecting the Slave Arm and Control System Components
To connect the slave arm to the slave controller, follow these steps:
1.
If you have a bilateral slave arm, connect the bilateral electronics cable to the
slave arm at the location shown in Figure 3-2.
2.
Connect the unilateral electronics cable to the slave arm at the location shown
in Figure 3-2.
For information on connecting the other ends of these cables to the slave controller, see the Titan II manipulator control system manual.
3.4 Connecting to Hydraulic Power
Before you proceed, see Chapter 1 for information on hydraulic input requirements.

3.4 Connecting to Hydraulic Power
Figure 3-2 Slave Arm Electrical and Hydraulic Connectors
WARNING
1. Activating hydraulic power with loose or reversed connections
can cause injury to personnel and/or damage to equipment.
2. If system return pressure exceeds 1000 psi at any time when slave
arm hydraulic power is enabled, injury to personnel can result and
damage to equipment will occur. If the hydraulic return passes
through a filter or is manifolded with other equipment returns before returning to the tank, check the return pressure when the filter and/or other equipment is running to be sure that return
pressure never exceeds 1000 psi.
3. Any obstruction in the hydraulic return line can cause injury to
personnel and/or damage to equipment.

3.6 Wireway Compensator Installation
Figure 3-5 Compensator Fittings
WARNING
The wireway compensator must be installed correctly and the wireway compensation system must be purged of all air before the slave
arm can be submerged. Severe damage may occur to the slave arm
if air is left in the system.
CAUTION
For best performance, purge the wireway compensation system monthly
or anytime the fluid is compromised.
CAUTION
The wireway compensator cannot be installed under water.
3.6.1 Checking for Wireway Air Leaks
Insure that all slave arm seals and joints are airtight before filling the wireway
compensation system with hydraulic fluid. This can be accomplished by two
methods.
The first method is to cap the wireway compensation system purge line with its
hydraulic plug, and then fill the system with air to 1 atmosphere or 15 psi. Check
011-0061, Version 1
3-7
3.7 Post-Installation Startup
Installation
for leaks by spraying the joints with a mild detergent or window cleaner. If air is
escaping from the joints, the detergent or window cleaner will foam.
The second method is to install a pressure gauge on the purge line. Fill the system with air to 1 atmosphere or 15 psi, remove the air supply, leave the system to
stabilize, and monitor the gauge pressure. If the pressure drops, check for leaks
by the method described above.
3.6.2 Filling the Wireway Compensation System
The item numbers in parentheses refer to parts in Figure 6-11.
1.
Make sure there are no leaks in the seals or joints. See section 3.6.1.
2.
Remove the hydraulic plug from the wireway compensation system purge line
and put the hose end into a bucket.
3.
Position the slave arm in a vertical position with the jaws up, and disconnect it
from its electrical power source.
4.
Attach a hose from the compensator output port (fitting) to the input port on the
underside of the azimuth. This port connects to the coaxial hose that contains the azimuth resolver wires. This hose starts at the azimuth lid, runs
through the upper arm, and goes to the junction box.
5.
Schilling Development recommends using a clean, pressurized insecticide
sprayer to fill the wireway compensation system. Attach the hose from the
sprayer to the compensator input (fill) valve.
6.
Force hydraulic fluid into the compensator. The fluid will fill up the accumulator and force out the compensator piston (3). Stop pumping hydraulic fluid
when the piston is fully extended. Let the system stabilize and the fluid run
into the wireway compensation system lines. When the piston recedes back
into the compensator, force more hydraulic fluid into the accumulator. Repeat until hydraulic fluid starts to run out of the purge line.
7.
Purge all air from the wireway compensation system. One way to check for air
is to run a hose from the purge line into a bucket of fluid and watch for bubbles. When all the air has been purged, cap the purge line with a hydraulic
plug.
8.
Release any further air by pushing a thumbnail against the side of the relief
valve (11) on the compensator until first air, and then fluid is released.
9.
Fill the compensator until the piston is fully extended.

Task Description
6.1 General Maintenance Information
WARNING
To prevent injury to personnel and damage to equipment, always
observe the following precautions when performing maintenance
on the manipulator system:
1. Wear safety goggles when working on or near the slave arm.
Even when the slave arm has been isolated from hydraulic pressure, residual pressure will remain in many arm components.
2. Before performing any repair procedures on the slave arm, turn
off power to the hydraulic power unit and disconnect the slave arm
from electrical power.
CAUTION
1. Any manipulator system component that contains PC boards is sensitive to damage from static electricity. While working on static- sensitive
equipment, wear an anti-static wrist band attached to earth ground or a
large metal object.
2. To avoid damage to the slave arm, do not use any lubricating compounds containing suspended particles such as molybdenum or graphite.
6.1.1 Required Practices and Procedures
Always observe the following practices and procedures when performing maintenance on the Titan II slave arm:
6-2
•
Before disjointing any slave arm components, remove power from the slave
controller.
•
Lubricate all slave arm o-rings with o-ring lubricant or petroleum jelly.
011-0061, Version 3
Maintenance
•
Lubricate all slave arm threads with a small amount of thread lubricant.
•
Avoid lubricants that contain particles such as molybdenum or graphite.
•
After every 100 operating hours, re-torque all outside fasteners.
6.2 Resolver Calibration
6.1.2 General Repair Information
•
After parts are disassembled, they need to be cleaned, degreased, and inspected before being reassembled.
•
Replace any o-ring that is broken, damaged, or shows signs of wear.
•
Observe required torques for all fasteners.
•
For some procedures, it is necessary to use a curved pick to remove o-rings.
•
For some procedures, it is necessary to use a bench vise to secure an assembly while it is being serviced.
•
For procedures where hydraulic connections are broken while the slave arm
is mounted on its base, be sure the tip of the arm is supported.
•
When reconnecting telemetry cables, make sure the identification information on the connectors matches before joining them.
6.2 Resolver Calibration
When you remove a resolver, you must carefully align it during reinstallation.
Each resolver has two 1/16-inch aligning spheres attached at the factory. These
spheres line up with notches in the corresponding parts of the assembly that the
resolver is mounted to. The resolver spheres fit only one way into their notches.
This positions the resolver correctly in the assembly, and eliminates the need for
calibration.
