X Input CtctrOpen 166 The input contactor has opened without a command from the
drive.Verify the contactor feedback and the 120V wiring to
the ACB.
• The drive system needs to have complete control over all contactors, so investigation of
the specific contactor fault is required.
• Verify contactor feedback.
• Verify the control power circuit for the contactor.
• Check permissive string to the contactor control relay (refer to drawing) - Check contactor/
breaker for physical malfunction (auxiliaries).
• Check ACB board inputs and outputs.
• Check ACB connector for loose connections or damaged connector J1
X Input IsoSwClsd 173 The input contactor isolation switch is closed when it was
expected to be open. Verify the isolation switch mechanical
set up and the 120V wiring to the ACB. Depending on the
Operating Mode of the drive, ensure that the switch is in the
proper position.
• Depending on the mode of operation (Normal, System Test, Open-Circuit Test, DC Current
Test, or Open-Loop), there are specific states for all the possible system isolation switches
(Refer to the description of HardwareOptions1, P141). Be sure the isolation switches are in the
proper position.
• Verify wiring feedback.
• Verify isolation switch mechanical auxiliary setup.
• READ ASSOCIATED DESCRIPTION.
