6.2 Service Procedures
The following service procedures provide instructions for component replacement.
6.2.1 Proximity Sensor Adjustment, Test, or Replacement
Parts required: Refer to
Tools required: 8 mm Allen wrench, 13 mm wrench
Supplies required: Loctite 222
The proximity sensors are very reliable and normally do not need to be replaced. Exhaust all other
possible solutions, check continuity, air supply, lubrication, and pneumatic components prior to
testing or replacing the sensor.
1. Place the Tool in a secure location.
2.
If you are testing or replacing the lock sensor make sure the Tool Changer is in the locked
position, if you are replacing the unlock sensor, make sure the Tool Changer is in the unlocked
position before continuing.
3.
Turn off and de-energize all energized circuits (e.g. electrical, air, water, etc.).
4. Disconnect any cables, air line, etc. if required.
5. Remove the (6) M10 socket head cap screws securing the Master plate assembly to the sensor
interface plate using an 8 mm Allen wrench. Refer to
6. Disconnect the sensor cable.
7. Using a 13 mm wrench, loosen the hex nut and unscrew the proximity sensor from the Master
plate assembly. Retain the washer from the sensor.
8.
To test the suspect sensor, connect the sensor cable and place a ferrous target in front of the
proximity sensor to confirm that the sensor is functional. The sensor lock or unlock signal
should read “on”(true) and the sensor LED should illuminate.
9. If the proximity sensor is not functioning, replace. Disconnect the sensor cable and discard.
10.
Back the sensor hex nut to the connector end of the new sensor.
11.
Thread the proximity sensor into the Master plate assembly until it touches the detection shaft,
then back the sensor off 1/2 turn.
CAUTION:
Do not operate locking mechanism with sensor touching the
detection shaft. Operating the locking mechanism with the sensor touching the
detection shaft will damage the sensor. Back off the sensor ½ turn and secure
with the set screw before operating the locking mechanism.
12. Connect the sensor cable. The proximity sensor LED should be illuminated.
13.
Holding the sensor in position, apply Loctite 222 to the proximity sensor threads between the
hex nut and the Master plate assembly. Tighten the hex nut and torque to 20 in-lbs (2.3 Nm)
using a 13 mm wrench.
14.
Attach the Master plate to the sensor interface plate using the (6) M10 socket head cap screws
using an 8 mm Allen wrench. Refer to
for torque and thread locker specifications.
15. If required, connect other utilities to the optional modules on the Master plate.
16.
Confirm the operation of the replaced sensor by issuing the lock command to lock a Tool to the
Master and then checking to see that the LED in the replaced Sensor body is on.
17.
After the procedure is complete, resume normal operation.
