GP40X MODULE INFORMATION
ANNUNCIATOR MODULE:
VARIOUS FAULT SIGNALS FROM THE 15 VDC CONTROL MODULES ARE PROVIOED TO THE
ANNUNCIATOR MODULE AN102. THESE FAULT SIGNALS RESULT IN TURN ON OF FAULT
INDICATING LIGHTS LOCATED ON THE MODULE FACEPLATE. THE AN102 MODULE HAS
PROVISIONS FOR SIX SEPARATE FAULT INDICATIONS. CLEARING THE FAULT WILL
NOT RESET THE FAULT INDICATING LIGHTS. THE FAULT INDICATING LIGHTS REMAIN
ON UNTIL THE MODULE IS RESET OR THE 15 VDC INPUT TO THE MODULE IS INTERRUPTED.
CURRENT
I~AXIMIZING
MODULE:
THE CURRENT MAXIMIZING MODULE CM100 MONITORS AVERAGE MOTOR CURRENT
150A/V AT RECEPTACLE 8 AND CHANGES THE OUTPUT RESISTANCE BETWEEN RECEPTACLES 5 AND 6. THIS MAY BE EITHER AN INCREASE OR A DECREASE IN RESISTANCE.
IF THIS CHANGE RESULTS IN AN INCREASE OF AVERAGE MOTOR CURRENT, ANOTHER CHANGE
IN RESISTANCE WILL BE MADE IN THE SAME DIRECTION. IF THE CHANGE RESULTS IN
A DECREASE OR NO CHANGE OF AVERAGE MOTOR CURRENT. A CHANGE IN RESISTANCE
WILL BE MADE IN THE OPPOSITE DIRECTION. A CHANGE IN RESISTANCE IS MADE
ABOUT ONCE EACH SECOND. THEREFORE, RESISTANCE CHANGES ARE MADE AS NECESSARY TO MAINTAIN OPERATION AT OR NEAR THE PEAK OF THE FRICTION CREEP CURVE.
DYNAMIC BRAKE REGULATOR MODULE:
(
THE DYNAMIC BRAKE REGULATOR MODULE DR100 MONITORS THE DYNAMIC BRAKING SIGNAL
FROM THE DYNAMIC BRAKE RHEOSTAT (24T SIGNAL) WHICH IS ESTABLISHED BY BRAKE
HANDLE POSITION. THIS SIGNAL IS CONVERTED INTO A TRACTION flOTOR FIELD
CURRENT REFERENCE SIGNAL ON UNITS EQUIPPED FOR FIELO CURRENT TRAINLINE
CONTROL (FCTLC) AND INTO A TRACTION MOTOR ARMATURE CURRENT (GRID CURRENT)
REFERENCE SIGNAL ON UNITS EQUIPPED FOR GRID CURRENT TRAINLINE CONTROL
(GCTLC).
OYNAMIC BRAKE PROTECTION MODULE:
THE DP100 MODULE PROVIOES OYNAMIC BRAKE PROTECTIVE FUNCTIONS OF GRID OVERCURRENT, GRID OVER-EXCITATION, ANO GRID OPEN-CIRCUIT. THE GRID OVER-CURRENT
FUNCTION RECEIVES A SIGNAL PROPORTIONAL TO DYNAIHC BRAKE GRID CURRENT ANO
INTERRUPTS THE FEED TO THE EQP RELAY WHEN THE LIMITING VALUE OF ABOUT 820
AMPERES IS REACHED. THIS FUNCTION PROVIDES BACK-UP PROTECTION IN CASE THE
DR MODULE FAILS TO REGULATE GRID CURRENT.
EXTENDED RANGE DYNAI'I! C BRAKE MODULE:
WHEN OPERATING IN DYNAMIC BRAKE AT PEAK BRAKING EFFORT SPEEO. TRACTION
MOTOR FIELD CURRENT IS APPROXIMATELY 875 AMPERES AND TRACTION MOTOR
ARMATURE CURRENT (DYNAMIC BRAKING GRIO CURRENT) IS APPROXIMATELY 760
AMPERES. AT TRACK SPEEDS ABOVE PEAK BRAKING EFFORT SPEED. THE DR100
MODULE REGULATES TRACTION MOTOR FIELD CURRENT AS NECESSARY TO LIMIT
BRAKING EFFORT SPEED. THE DR100 MODULE REGULATES TRACTION MOTOR FIELD
CURRENT AS NECESSARY TO LIMIT BRAKING GRID CURRENT TO APPROXIf~TELY 760
AMPERES. AT TRACK SPEEDS BELOW PEAK BRAKING EFFORT SPEED. TRACTION MOTOR
7
-- ...,
(
FIELD CURRENT IS LIMITED TO ABOUT 875 AMPERES AND DYNAMIC BRAKING GRID
CURRENT DECREASES AS TRACK SPEED DECREASES. BRAKING EFFORT MAY BE MAINTAINED AT A RELATIVELY HIGH VALUE AT TRACK SPEEDS BELOW PEAK BRAKING
EFFORT SPEED BY SHORTING OUT PORTIONS OF THE DYNAMIC BRAKING GRIDS:
THEREBY DECREASING BRAKING GRID RESISTANCE, WITH A RESULTING INCREASE IN
BRAKING GRID CURRENT.
THE DE100 MODULE MONITORS THE TRACTION MOTOR FIELD CURRENT SIGNAL AND THE
BRAKING GRID CURRENT SIGNAL, THEN INITIATES PICKUP OF THE DYNAMIC BRAKING
GRID SHORTING CONTACTORS WHENEVER THE RATIO OF THE BRAKING GRID CURRENT
SIGNAL TO THE FIELD CURRENT SIGNAL (IG/IF) DECREASES BELOW A PREDETERMINED LEVEL.
DYNAfilC BRAKING GRID PROTECTION MODULE:
THE DG100 MODULE CONTAINS A DETECTOR STAGE AND AN OUTPUT STAGE. THE
DETECTOR STAGE MONITORS GRID CURRENT AND GRID VOLTAGE. A POSITIVE SIGNAL
IS PROVIDED FROM THE DETECTOR STAGE TO THE OUTPUT STAGE IF THE RATIO OF
GRID VOLTAGE TO GRID CURRENT RISES ABOVE A PREDETERMINED VALUE. THIS
POSITIVE SIGNAL TO THE OUTPUT STAGE RESULTS IN REMOVING EXCITATION FROM
THE MAIN GENERATOR AND THE B CONTACTOR ALSO DROPS OUT. THIS PROTECTS
THE BRAKING GRIDS FROM BURN OUT DUE TO OVERHEATING.
MOTOR TEMPERATURE SIMULATOR MODULE:
(
THE MOTOR TEMPERATURE SIMULATOR MODULE MS100 PROVIDES A SIGNAL TO PIN
26 OF THE LOAD CONTROL MODULE LC100, WHICH RESULTS IN HIGHER PERFORMANCE
DURING LOW DRAG SPEED WHEN TRACTION MOTOR TEMPERATURE IS BELOW 170oC, AND
GRADUALLY REDUCES PERFORMANCE TO NORMAL AS TRACTION MOTOR TEMPERATURE
INCREASES TO 180oC. THIS ALLOWS FOR EXTRA PULLING POWER WHEN THE MOTORS
ARE COOLER AND PROTECTS THE MOTORS BY REDUCING PULLING POWER WHEN THE
MOTORS ARE HOT.
MOTOR FEEDBACK MODULE:
THE MOTOR FEEDBACK MODULE Hil 00 MONITORS THE CURRENT OF EACH TRACTION MOTOR
AND DEVELOPS SIGNALS PROPORTIONAL TO THE LOWEST MOTOR CURRENT, HIGHEST
MOTOR CURRENT, LOWEST MOTOR CURRENT ABOVE 75 AMPERES, AND AVERAGE MOTOR
CURRENT. THE FM100 MODULE USES THESE SIGNALS TO PROVIDE POWERED LOCKED
WHEEL PROTECTION, OPEN MOTOR CIRCUIT INDICATION, AND TO DRIVE THE LOAD
INDICATING METER.
GOVERNOR CONTROL
~IODULE:
THE GOVERNOR CONTROL MODULE PROVIDES INTERFACE FUNCTIONS FROM THE THROTTLE
SWITCHES TO THE LC ~IODULE AND TO THE GOVERNOR SPEED SETTING SOLENOIDS
DURING POWER OPERATION. THE GC MODULE ALSO PROVIDES INTERFACE BETWEEN
THE DYNAMIC BRAKING 21T CIRCUIT AND THE GOVERNOR SPEED SETTING SOLENOIDS
DURING DYNAMIC BRAKE OPERATION.
8
I
LOAD CONTROL MODULE:
THROTTLE SIGNALS AND THE LOAD REGULATOR SIGNAL ARE APPLIED TO. THE LC
MODULE TO OBTAIN CURRENT LIMIT, VOLTAGE LIMIT, AND KILOWATT LIMIT REFERENCE
SIGNALS FOR EACH THROTTLE POSITION. THE LC MODULE USES THE MAIN GENERATOR
OUTPUT CURRENT AND VOLTAGE SIGNALS TO DEVELOP CURRENT, VOLTAGE, AND KILOWATT
FEEDBACK SIGNALS.
THE LC MODULE COMPARES THE FEEDBACK SIGNALS WITH THE LIMIT REFERENCE
SIGNALS. THE SIGNAL TO THE SE MODULE IS REMOVED IF ANY ONE OF THE FEEDBACK SIGNALS TENDS TO RISE ABOVE ITS RESPECTIVE LIMIT REFERENCE SIGNAL.
REMOVING THE SIGNAL FROM THE SE MODULE REMOVES THE GATING PULSES FROM THE
SILICON CONTROLLED RECTIFIED ASSEMBLY SCR. REMOVAL OF THE GATING PULSES
BLOCKS EXCITATION FROM THE MAIN GENERATOR FIELD WHICH RESULTS IN A DECREASE
IN MAIN GENERATOR OUTPUT. THE GATING SIGNALS ARE REAPPLIED WHEN ALL THE
FEEDBACK SIGNALS DECREASE BELOW THEIR RESPECTIVE LIMIT REFERENCE SIGNALS.
GENERATOR FEEDBACK MODULE:
(
THE GENERATOR FEEDBACK MODULE FG100 MONITORS HIGH VOLTAGE DC FEEDBACK
SIGNALS FROM THE MAIN GENERATOR AND FROM THE LOAD REGULATOR OR THE
DYNAMIC BRAKE RHEOSTAT. THE SIGNALS ARE ELECTRICALLY ISOLATED, FILTERED,
AND ADJUSTED FOR CONTROL USAGE. THE MAIN GENERATOR VOLTAGE SIGNAL RATIO
IS 125V/V. THE LOAD REGULATOR SIGNAL AND THE DYNM\IC BRAKE RHEOSTAT
SIGNAL RATIO IS 7.3V/V.
THE FG100 MODULE ALSO MONITORS THE MAIN GENERATOR CURRENT FEEDBACK SI~NALS
FROM THE CURRENT TRANSFORMERS. THESE SIGNALS ARE RECTIFIED FILTERED, AND ADJUSTED FOR CONTROL USAGE. THE MAIN GENERATOR CURRENT SIGNALS HAVE A RATIO
OF 600A/V FOR FOUR MOTOR LOCOMOTIVES AND 900A/V FOR SIX AXLE LOCOMOTIVES.
flOTOR E/N GENERATOR MODULE:
"
THE EN100 MODULE ESTABLISHES WHEEL CREEP LIMIT BY LIMITING MAIN GENERATOR
OUTPUT VOLTAGE TO A VALUE PROPORTIONAL TO TRUE TRACK SPEED PLUS AN ALLOWABLE WHEEL CREEP. THE PERCENTAGE OF ALLOWABLE WHEEL CREEP CHANGES AS
TRACK SPEED CHANGES. THE ALLOWABLE WHEEL CREEP AT'30 11ILES PER HOUR IS
ABOUT 9% AND DECREASES TO ABOUT 3% AT 100 MILES PER HOUR. ASSUME THAT
MAIN GENERATOR OUTPUT VOLTAGE IS 1000 VOLTS A> A TRUE TRACK SPEED OF 50
MILES PER HOUR WITH NO WHEEL CREEP AND 1060 VOLTS AT A TRUE TRACK SPEED
OF 50 MILES PER HOUR WITH 6% WHEEL CREEP. ASSUME THAT MAXII1Ur1 WHEEL CREEP
IS LIMITED TO 6% AT 50 MILES PER HOUR. iHEREFORE, f~IN GENERATOR OUTPUT
VOLTAGE IS LIMITED TO 1060 VOLTS AT 50 MILES PER HOUR. THE EN MODULE
OPENS THE SENSOR STRING TO REDUCE EXCITATION IF MAIN GENERATOR OUTPUT
VOLTAGE RISES ABOVE 1060 VOLTS AT A TRUE TRACK SPEED OF 50 MILES PER
HOUR. THEREFORE, THE EN flODULE LIMITS WHEEL CREEP TO A flAXIMUM OF 6% AT
50 MILES PER HOUR BY LIMITING MAIN GENERATOR OUTPUT VOLTAGE TO A VALUE
PROPORTIONAL TO TRUE TRACK SPEED PLUS THE ALLOWED WHEEL CREEP.
EXCITATION LIMIT MODULE:
THE EXCITATION LIMIT MODULE EL100 MONITORS MAIN GENERATOR EXCITATION
CURRENT ANu PROVIDES A SIGNAL TO OPEN THE SENSOR STRING ON THE LC MODULE
9
-IF EXCITATION CURRENT RISES ABOVE A PREDETERMINED LEVEL. OPENING THE
SENSOR STRING REMOVES EXCITATION FROM THE 11AIN GENERATOR, BUT THE LARGE
INDUCTANCE OF THE MAIN GENERATOR FIELD WINDINGS PREVENTS A SUDDEN COLLAPSE
OF THE FIELD. WHEN EXCITATION CURRENT DECREASES BELOW THE PREDETERMINED
LEVEL, THE SENSOR STRING IS CLOSED TO REAPPLY EXCITATION CURRENT. THEREFORE, EXCITATION IS REGULATED AROUND THE PREDETERMINED LEVEL.
WHEEL OVERSPEED MODULE:
AT LOW DRAG SPEEDS, THE EXCITATION LIMIT MODULE EL100 LIMITS MAIN GENERATOR
FIELD CURRENT TO THE DESIRED MAXIMUM LEVEL. ,1HEN TRACK SPEED INCREASES ABOVE
A PREDETERMINED SPEED, THE WHEEL OVERS PEED MODULE W0100 PROVIDES A RECALIBRATION SIGNAL TO THE EL 100 I~ODULE. THIS RECALIBRATION OF THE EL 100 MODULE
RESULTS IN LIMITING MAIN GENERATOR FIELD CURRENT TO A LOWER LEVEL WHEN
TRACK SPEED RISES ABOVE THE PREDETERMINED SPEED. AT SOME HIGHER TRACK
SPEED THE WO MODULE OPERATES TO DROP OUT THE EQP RELAY TO PREVENT WHEEL
OVERS PEED.
SENSOR MODULE:
(
THE SENSOR MODULE SE100 CONTROLS MAIN GENERATOR FIELD EXCITATION CURRENT
LEVEL. FIELD EXCITATION CURRENT IS PROVIDED BY THE D14 ALTERNATOR THROUGH
SILICON CONTROLLED RECTIFIERS SCR1, SCR2, AND SCR3 ON THE SCR ASSEMBLY.
THESE SILICON CONTROLLED RECTIFIERS WILL NOT CONDUCT UNTIL THEY ARE
FORWARD BIASED (ANODE POSITIVE WITH RESPECTIVE TO CATHODE) AND A GATING
SIGNAL IS APPLIED TO THE CATHODE GATE. THE GATING SIGNAL IS A VOLTAGE, APPLIED
TO THE CATHODE GATE, WHICH IS POSITIVE WITH RESPECT TO THE CATHODE. AFTER
CONDUCTION STARTS, THE GATING SIGNAL LOSES CONTROL, AND CONDUCTION CONTINUES AS LONG AS THE ANODE IS POSITIVE WITH RESPECT TO THE CATHODE.
SANDING MODULE:
THE SANDING f~DULE SA100 PROVIDES SIGNALS TO THE APPLICABLE SANDING MAGNET
VALVES WHEN AN AUTOMATIC SANDING SIGNAL OR THE EMERGENCY SANDING SIGNAL IS
APPLI ED TO THE SA MODULE. THE SA MODULE WI LL RESPOND TO MANUAL SAND ING
SIGNALS FROM THE f~NUAL SANDING LEVER OR FROM THE LEAD TRUCK SAND SWITCH
PRIOR TO TRANSFER TO THE SUPER SERIES MODE OF OPERATION, PROVIDED TRACK
SPEED IS BELOW FIVE MILES PER HOUR. THIS PROVIDES FOR THE APPLICATION OF
SAND TO INCREASE ADHESION WHEN STARTING OUT FROM STANDSTILL.
VOLTAGE REGULATOR MODULE:
THE VOLTAGE REGULATOR MODULE VR IS A SOLID-STATE VOLTAGE REGULATOR DESIGNED
TO MAINTAIN OUTPUT VOLTAGE OF THE AUXILIARY GENERATOR TO WITHIN +1 VOLT OF
THE "SET POINT." THE VR MODULE IS USUALLY ADJUSTED FOR A NOMINAL OUTPUT
VOLTAGE OF 74 VOLTS FROfI THE AUXILIARY GENERATOR, BUT CAN BE ADJUSTED FOR ANY
OUPUT BETWEEN 71 AND 77 VOLTS. THE VR MODULE WILL MAINTAIN THE OUTPUT TO
WITHIN +1 VOLT OF THE "SET POINT" AT AUXILIARY GENERATOR ROTATING SPEEDS BETWEEN 825 AND 3,000 RPM, AT ANY LOAD BETWEEN NO LOAD AND FULL RATED LOAD
AND WITHIN A TEMPERATURE RANGE OF -40 0 TO + 80 0 C.
