How do I clear the F0071 on a GT100 unit?
Issue:
Clearing the fault code 0071
Product Line:
GT100, GT250
Environment:
Installations that use a three phase GT unit
Cause:
The fault code F0071 appears but it does not clear after pressing F1 and power cycling the unit
Resolution:
ONLY QUALIFIED PERSONNEL WITH PROPER EQUIPMENT CAN WORK ON THIS UNIT FOR TROUBLESHOOTING
If the code does not clear after power cycling the unit and pressing F1, you need to open and lock out and tag out the external DC and AC breakers. Once this has been done and you confirmed no live voltages on the DC and AC side of the unit, you can close the S1 switch by using an adjustable wrench or some other means to simulate a closure. You can then check continuity across the auxiliary switch S2, which is attached to S1. You can confirm continuity at the CCU board in connections P2-9 and P3-3
