je vais usiner une bague en DELRIN pour remplacer celle

Transcription

Nous avons un pilote automatique Raymarine ST2000+ qui nous a rendu de grands services depuis 3 ans.
Seulement voilà, depuis quelques temps nous constatons un jeu anormal dans le bras du pilote avec de temps
en temps un cap plus qu’aléatoire…
Après un démontage rapide de la bête, nous trouvons quelques morceaux de plastique qui traînent dans le
corps du pilote.
•Un joint torique ( celui qui assure l’étanchéité du bras ) est cassé. Les morceaux sont tombés dans le
logement du compas et en perturbent le fonctionnement. Il faut les retirer à coup de pince brucelle.
•Des petits bouts de plastique noir se promènent sous l’extrémité de la vis à bille. Rien de bien
encourageant…
Voilà qui explique probablement le jeu dans le bras du pilote.
Il faut démonter entièrement le pilote pour réparer les différentes pièces. D’abord la vis à bille, il y a des
morceaux de plastique qui en tombent et elle a un jeu excessif. Je décide alors de prendre le risque de la
démonter intégralement sans savoir si j’arriverais ensuite à remettre tous les éléments !
Je me retrouve assez vite avec la vis d’un côté et une trentaine de billes d’1mm de diamètre qui ne demandent
qu’à sauter partout sur mon espace de travail.
Il faut replacer les billes sur le pas du palier en bronze en les « collant » avec de la graisse. Mais avant celà
je vais usiner une bague en DELRIN pour remplacer celle qui était cassée. A priori elle servait à limiter le
jeu dans la vis.
Cette baque ressemble en plus large à celle en blanc sur cet éclaté de vis à bille.
Après un tour dans LibreCad / HeeksCad me voilà en possession d’une belle bague toute simple qui
rentre parfaitement dans son logement. Vive la fraiseuse numérique !
La bague est collée à la sortie du palier avec de la résine époxy.
Voilà le palier est prêt à accueillir les billes. Reste un long travail de patience ! L’intérieur du pas de vis est
badigeonné de graisse silicone et les billes sont placées une à une dans leur logement. Quel travail, il me
faudra pas loin de 45 min pour tout remettre en place.
1. Les munitions
2.L’arme fatale
3.La cible
Ça y est, la vis est remontée, elle fonctionne parfaitement.Ouf !
Deuxième problème, le jeu d’1cm dans la barre. En démontant la tige filetée, je vois que le support du
roulement à l’extrémité de la vis est cassé. En effet, lors des virements de bord, la vis vient « taper » sur le
support du roulement ce qui fini par le fracturer. Le roulement n’est plus tenu et il se promène le long de la
tige. Seule la poulie à l’extrémité de la vis vient buter sur le support en aluminium et empêche la vis de sortir
complètement de son logement… Je ne suis pas le seul a avoir constaté ce problème ce qui me fait penser
à un défaut de conception. Dommage qu’un pilote qui n’est quand même pas donné souffre d’un problème
de fragilité d’une pièce en plastique qui doit coûter quelques euros à produire !
Je vais supprimer la partie cassée pour la remplacer par une pièce en DELRIN qui sera fixée à l’aide de 2
vis sur la plaque de support en aluminium.
On voit la partie arrachée sur le support du roulement

1. Description
This section of the Service Manual details the Servicing Procedures for the
Autohelm ST1000+ Tiller Autopilot, Catalogue Number Z323 and Autohelm
ST2000+ Tiller Autopilot, Catalogue Number Z324.
2. Operation
Full details of operation and calibration are given in the User Handbook,
Publication Number 81130-1
ST1000+ and ST2000+
3. Disassembly and Assembly
Before dismantling the autopilot, check the operating sense (port/starboard), if
the PCB condition allows. All new PCBs are factory set to starboard operating
sense. A replacement PCB in a unit set up for port operation must be set to port
operation.
The autopilot may be calibrated to suit a particular vessel. Note the calibration
settings and set up the new PCB if required.
If the spares PCB contains software of a higher issue than the PCB it replaces,
the relevant Operating Supplement(s) must be included when the equipment is
returned to the customer.
Replacement PCBs are set up as ST1000+.
Component identification numbers refer to Figure 1, Exploded View, unless a
detail figure is identified at the start of a section.
3.1 Upper Case Removal
1. Ensure the drive unit is fully retracted
2. Remove the case securing screws (10, 8 off)
3. Lift off the upper case (1)
Do not run the actuator assembly with the upper case removed and the PCB in
place. There is insufficient clearance between the guide bridge and the PCB and
damage to PCB components may result.
If it is required to run the actuator the PCB should be unscrewed and lifted slightly.
3.2 PCB Removal
All work on the PCB should be carried out taking normal static precautions.
1. Remove the upper case (1)
2. Remove the screws (19, 3 off) securing the PCB
3. Lift the PCB off its support pillars and disconnect the Fluxgate flexible circuit
(16) from connector SK1. Disconnect the power, data, screen, NMEA +,
NMEA- and motor spade connectors (22, 23, 24) from the PCB.
Replacement PCBs are supplied without an LCD. If changing the PCB refer to
section 3.3 for instructions to remove and transfer the display assembly to a
replacement PCB.

4. Lower the PCB onto the location pillars
5. Lock in place with the securing screws (19, 3 off)
6. Power up the unit and confirm display operation by momentarily pressing the 1 and +10 degree keys. The display should count up from 0 to 9 on all four
characters, then display all other annotations. Observe the display and
confirm all segments are switching on.
3.9 Upper Case Refitting
1. Clean the LCD and the window in the upper moulding with a lint free anti static
wipe
2. Ensure the case seal is seated correctly in the outer groove around the
perimeter of the lower case
3. Ensure the O ring seal (5) is located around the pivot pin (4)
4. Lower the upper case onto the assembly and locate with the securing screws
(10, 8 off). Do not over tighten (8 in Ibs max.).
ST1000+ and ST2000+
4. Special Functions
4.1 Changing the Operating Sense
All units are supplied from the factory set up as Starboard.
The operating sense of the autopilot can be reversed by pressing the +1° and -1°
course change keys together for 5 seconds
The unit should beep for 10 seconds to confirm change over and the display
should show the new setting, either Port or Starboard.
4.2 Display Test
A special display test feature in the ST1000/200+ software checks that the
display assembly is fitted correctly after changing the PCB. Display test is
switched on by momentarily pressing the -1° and +10° keys together.
The display should scroll all four characters through from 0 to 9 and then display
each annotation. This sequence continues until the Standby or Auto key is
pressed or the unit is powered down.
4.3 Autopilot Type Selection
The ST1000+ and ST2000+ autopilots use the same PCB (Q218), but gears in
the ST1000+ and ST2000+ drive modules are different, so each pilot runs a
different program. Both sets of software are contained within the same chip.
To select the correct program:
1. Press the -10° and +1° keys until the display shows the pilot type number,
2000 or 1000 (approx. 5 seconds)
2. Press the -10° and +1° keys again until the display flashes the pilot type
number (approx. 5 seconds)
3. Select the correct pilot type using the +1° and -1° keys
4. Save the setting by pressing the -10° and +1° keys until the normal Standby
display appears (approx. 2 seconds)
Changing Autopilot type clears all calibration setting/compass linearisation and
returns the unit to factory setting.
4.4 Display of Software Code
The software code of the pilot can be displayed by switching the pilot to standby
mode and pressing the Standby key until the display shows P followed by a
number (approx. 10 seconds).
The number indicates the version of software fitted, for example, P 0 6 indicates
Version 6 software.
12
ST1000+ and ST2000+
4.5 Calibration Lockout
Access to the compass linearisation and calibration functions on the ST1000+/
2000+ autopilots can be prevented. This can be a useful feature, for example, to
charter boat operators who spend a lot of time tuning the pilot to the boat, only to
find a customer alters the settings at a later date.
Any attempt to linearise the compass or enter calibration when the lockout
function is enabled results in the display showing Cal Off. The user cannot then
change any settings.
To disable calibration:
1. Press and hold the -1° and Standby keys for 10 seconds until the display
shows CAL ON
2. Toggle calibration access between ON and OFF using the -1° and +1° keys
3. Store the selected setting by pressing the -1° and Standby keys for 10
seconds.
