This troubleshooting guide assumes that your Main PD Rack is wired and fully operational. For more information on that process, see UNKNOWN DOCUMENT: Load In/Take Down – Hooking Up Power.
¶ All Motors Unresponsive
If no motors in the system will operate, follow this section.
- Ensure that power is reaching the Motor Power Distribution (Motor PD) system. If so, move to step 2. The indicators for this can be found in the middle of the Motor PD and should be illuminated red (Image 1).
- If these LEDs are not illuminated, ensure that the C-5 Connector going into the Motor PD is connected at both the Motor PD end and at the Main Power Distribution Rack (PD Rack). If these LED’s are illuminated, move on to step 2.
- Ensure that the breaker for the Motor PD located on the PD Rack is turned on.
- If the PD Rack has a Spare C-5 Connector, move the Motor PD C-5 to the Spare line and energize the appropriate circuit breaker on the PD Rack.
- If the campus has a Spare C-5 Cable, replace the current C-5 Cable.
- If none of these steps illuminate the 3 LEDs, call Production Support immediately so that a replacement Motor PD can be mobilized.
- Ensure that the Keyswitch on the Motor PD is rotated to ‘Phase ABC’ (Image 2).
- Ensure that the branch breakers on the Motor PD system are energized (Image 3).
- Ensure that the Tajimi Motor Pendant Cable is properly seated on both the Motor PD end and on the Motor Pendant End (Image 4). This cable must click into place on both ends. The red dots on the cable ends and the connectors on the Motor PD and Pendant Controller must line up for the connection to be properly seated.
- Ensure that either the Power Switch (Image 5) or Lock Keyswitch (Image 6) are set to the ‘On’ Position.
- For campuses with the Motor Pendant Controller in Image 6, turn the E-Stop Button (Circled in Yellow) ¼ turn clockwise to release it.
The red Power LED should illuminate and you should hear the contactor of the Motor PD engage at this point. If neither of these things happen, please call Production Support immediately for assistance.
- For campuses with the Motor Pendant Controller in Image 6, turn the E-Stop Button (Circled in Yellow) ¼ turn clockwise to release it.
¶ Single Motor Unresponsive
- Ensure that ALL circuit breakers on the Motor PD are energized (Image 7).
- Ensure that the Tajimi Motor Pendant Cable is properly seated on both the Motor PD end and on the Motor Pendant End (Image 8). This cable must click into place on both ends. The red dots on the cable ends and the connectors on the Motor PD and Pendant Controller must line up for the connection to be properly seated.
- Ensure that ALL Motor Control Cables are properly seated in their correct channel on the Motor PD. It is imperative that the pin and slot on the connectors is properly aligned and that the screw end sleeve is completely fastened (Image 9).
- Ensure that the Motor Control Cable for the Motor in question is properly seated into the Motor. It is imperative that the pin and slot on the connectors is properly aligned and that the screw end sleeve is completely fastened (See Image 9 above).
- If a spare channel exists on the Motor PD, move the Motor Control Cable for the Motor in question to the spare channel. Remember to engage that channel on the Motor Control Pendant and test the function of the motor in question. If moving to the spare channel on the Motor PD resolves the issue, please contact Production Support anyway to log the issue.
- If the campus has a spare Motor Control Cable, temporarily run that cable to the Motor in question.
