ONLINECLAMP SENSORS#

Sensor_XP-LCA-13184-qty1 per AutoChanger#

Scope:

This operation has to be considered if the position of the OnlineClamp X+ cannot be read on the FCS. Since every signal (OnlineClampX+ Open/OnlineClampX+ Closed) is doubled by a complementary one, the FCS is able to detect a sensor error.

The position of the Sensor_XP-LCA-13184 is given on #05-LCA-12946.

Material needed:

  • Small cross-point screwdriver qty 1

  • Small flat screwdriver qty 1

Procedure:

  1. Make sure there is no filter in the AutoChanger and the power supplies are turned off.

  2. Remove the connector by levering between the socket and the connector with a flat screwdriver. Make sure not to pull on the cable. The correct position at which the flat screwdriver has to be inserted is shown in below:

  3. Remove the screw #06-LCA-13184 with a small cross-point screwdriver.

  4. Pull the Sensor_XP and replace it by a new one. Make sure to fully insert the spigot of the Sensor_XP inside the clamp_XP #02-LCA-12946 as shown below:

  5. Screw in the screw #06-LCA-13184 with a small cross-point screwdriver.

  6. Plug the connector to the socket by pushing on the connector without bending the cables.

Sensor_XM-LCA-13166-qty1 per AutoChanger#

Scope:

This operation has to be considered if the position of the OnlineClamp X-cannot be read on the FCS. Since every signal (OnlineClampX-Open/OnlineClampX-Closed) is doubled by a complementary one, the FCS is able to detect a sensor error.

The position of the Sensor_XM-LCA-13166 is given by #05-LCA-12991.

Material needed:

  • Small cross-point screwdriver qty 1

  • Small flat screwdriver qty 1

Procedure:

  1. Make sure there is no filter in the AutoChanger and the power supplies are turned off.

  2. Remove the connector by levering between the socket and the connector with a flat screwdriver. Make sure not to pull on the cable. The correct position at which the flat screwdriver has to be inserted is shown in below:

  3. Remove the screw #06-LCA-13166 with a small cross-point screwdriver.

  4. Pull the Sensor_XM and replace it by a new one. Make sure to fully insert the spigot of the Sensor_XM inside the clamp_XM #02-LCA-12991 as shown below:

  5. Screw in the screw #06-LCA-13166 with a small cross-point screwdriver.

  6. Plug the connector to the socket by pushing on the connector without bending the cables.

Sensor_YM-LCA-13160-qty2 per AutoChanger#

Scope:

This operation has to be considered if the position of the OnlineClamp Y-cannot be read on the FCS. Since every signal (OnlineClampY-Open/OnlineClampY-Closed) is doubled by a complementary one, the FCS is able to detect a sensor error.

The position of the Sensors_XP-LCA-13184 is given by #06-LCA-13036.
WARNING: the sensor corresponding to the position OnlineClampY-Closed is on the left on LCA-13036 whereas the sensor corresponding to the position OnlineClampY-Open is on the right.

Material needed:

  • Small cross-point screwdriver qty 1

  • HE_Sensor_Unpluging_Tool LCA-12981 qty 1

Procedure:

  1. Make sure there is no filter in the AutoChanger and the power supplies are turned off.

  2. Unscrew the screw #06-LCA-13036 with a small cross-point screwdriver.

  3. Unplug the connector of the sensor with the HE_Sensor_Unpluging_Tool LCA-12981. Make sure not to pull the cable but the connector.

  4. Replace the Sensor_XP-LCA-13184 by a new one.

  5. Screw in the the screw #06-LCA-13036 with a small cross-point screwdriver.

LATERAL LATCH DETECTION#

Truck_Sensor_Board_XM-LCA-13006-qty1 per AutoChanger#

Scope:

This operation has to be performed if the Lateral latch detection LCA-13005 or LCA-13006 does not work properly. For instance, Filter ID reading is incorrect. Other reasons are easy to detect since every signal is doubled by a complementary one (Latch Open/LatchClosed/Filter engaged). Thus, the FCS is able to detect a sensor error.

Material needed:

  • Small cross-point screwdriver qty 1

  • External (shaft) circlip plier qty 1

Procedure:

  1. Make sure there is no filter in the AutoChanger.

  2. Power on the AutoChanger by turning on the tree power supplies: Clean, Safety and Dirty powers on the electrical bay.

  3. Move the trucks to position 680000 using “MoveToAbsoluteTargetPosition” command on the FCS. This position corresponds to the maximal elongation of the cables between the Swing arm Plates #01-LCA-12812/#03-LCA-12812 and the Truck Plates #01-LCA-12802/#02-LCA-1282.

  4. Turn off Clean, Safety and Dirty powers supplies on the electrical bay.

  5. Remove the 3 screws #15-LCA-12812 that are holding the cable clamps #04-LCA-12812 with a small cross-point screwdriver.

  6. Unplug the connectors of the Latch Actuator #03-LCA-12829 and those of the Lateral latch detection LCA-13005/ LCA-13006. Make sure not to pull on the cable but only on the connectors.

  7. Remove the circlips #12-LCA-12802 using an external circlip plier.

  8. Thoroughly remove shim rings #10-LCA-12802 and #11-LCA-12802. Make sure to identify them since you will need to put them back at the same location (thickness varies on each side of swing arm plate X minus #03-LCA-12812). Please note there is no shim rings on X plus side.

  9. Unscrew the screw #15-LCA-12812 that is holding the cap #19-LCA-12812 with a small screwdriver.

  10. Remove cap #19--LCA-12812 (for X plus side) or #20--LCA-12812 (for X minus side).

  11. Replace the Lateral latch detection #18-LCA-12812 (for X minus side) or #17-LCA-12812 (for X plus side) by a new one.

  12. Make sure there is no electrical contact between Swing arm plates #01-LCA-12812/#03-LCA-12812 and the Lateral latch detection #18-LCA-12812/17-LCA-12812. This is granted by the insulators #16-LCA-12812.

  13. Put the cap #19-LCA-12812 (for X plus side) or #20-LCA-12812 (for X minus side) back.

  14. Screw them by tightening #15-LCA-12812 with a small cross-point screwdriver.

  15. Put back shim rings #10-LCA-12802, swing arm plate X minus #03-LCA-12812, shim rings #11-LCA-12802. (only swing arm plate X plus #01-LCA-12812 for X plus side).

  16. Mount the circlips #12-LCA-12802 using a circlip plier.

  17. Plug the connectors of the Latch Actuator #03-LCA-12829 and those of the Lateral latch detection LCA-13005/ LCA-13006.

  18. Put the cables inside the cable clamps #04-LCA-12812 and tighten the screws #15-LCA-12812 with a small cross-point screwdriver. Make sure not to pinch the cables.

  19. Power back on the autochanger by turning on Clean, Safety and Dirty power supplies on the electrical bay #04-LCA-13140.

  20. Move the trucks to HandOff position using the command “GoToHandOff”.
