7-9-4 XY Brake Motors Troubleshooting
NOTE: Cables are not labeled at the XY controller, so right side and left side motors are not defined.
When troubleshooting the XY brake motors, keep this in mind:
• The rear motors are #1 and #3.
• The front motors are #2 and #4.
• Motor #1 and #2 are on the same side.
• Motor #3 and #4 are on the same side (opposite to motor #1 and #2).
If you are in a silent environment, it may be possible to hear which motor is activated during the test.
7-9-5 Z Movement fails
• If it is impossible to lower the Top Console, but moving it upwards, works OK, it indicates that one
of the control switches is stuck in “Up” position.
• If you have to help the Top Console up when moving upwards, but the motor assistance work OK
when lowering the Top Console, it indicates that the gas spring inside the Z Mechanism is failing.
- Replace the Z Mechanism.
