Compressor Wye-Delta Starter Current Increase Failure

Alarm 132-10 — Circuit A (A1.10)

Alarm 133-10 — Circuit B (B1.10)

Criteria for Trip — The alarm criterion is checked during compressor start-up. This alarm will be generated if the current in Delta mode is not more than 25% greater than the current in Y mode within 550 ms.

Action to be Taken — The compressor will be stopped.

Reset Method — Manual

Possible Causes — If this condition is encountered, check the following items:

•power supply failure to the delta contactor

•faulty wiring to the delta contactor

•faulty CPM board

•faulty current toroid

Compressor Contactor Failure

Alarm 132-11 — Circuit A (A1.11)

Alarm 133-11 — Circuit B (B1.11)

Criteria for Trip — The alarm criterion is checked during compressor shut-down. This alarm will be generated if the cur- rent is greater than 15% of the MTA on at least one phase for 10 continuous seconds.

Action to be Taken — The compressor will be stopped.

Reset Method — Manual

Possible Causes — If this condition is encountered, check the following items:

•faulty or welded contactor

•faulty wiring

•faulty CPM board

Compressor Unable to Stop Motor

Alarm 132-12 — Circuit A (A1.12)

Alarm 133-12 — Circuit B (B1.12)

Criteria for Trip — The alarm criterion is checked during compressor shut-down. This alarm will be generated if after three attempts to turn off the compressor outputs and the cur- rent is still greater than 15% of the MTA on at least one phase for 10 continuous seconds.

Action to be Taken — The compressor will be stopped.

Reset Method — Manual

Possible Causes — If this condition is encountered, check the following items:

•faulty or welded contactor

•faulty wiring

Compressor Phase Reversal

Alarm 132-13 — Circuit A (A1.13)

Alarm 133-13 — Circuit B (B1.13)

Criteria for Trip — The alarm criterion is checked during compressor start-up. This alarm will be generated if the CPM board detects a phase reversal from the current toroid.

Action to be Taken — The compressor will be stopped.

Reset Method — Manual

Possible Causes — If this condition is encountered, check the following items:

•if power supply lead at the terminal block is not operating at the correct phase

•if power supply is crossed when going through the current toroid

Compressor MTA Configuration Fault

Alarm 132-14 — Circuit A (A1.14)

Alarm 133-14 — Circuit B (B1.14)

Criteria for Trip — The alarm criterion is checked whether the compressor is ON or OFF. This alarm will be generated if the MTA setting is out of the allowed MTA range.

Action to be Taken — The compressor will be stopped.

Reset Method — Manual

Possible Causes — If this condition is encountered, check the following items:

•incorrect MTA settings

•faulty CPM board

Compressor Configuration Switch Mismatch

Alarm 132-15 — Circuit A (A1.15)

Alarm 133-15 — Circuit B (B1.15)

Criteria for Trip — The alarm criterion is checked whether the compressor is ON or OFF. This alarm will be generated if the CPM board S1 and S2 setting does not match software configuration.

Action to be Taken — The compressor will be stopped.

Reset Method — Manual

Possible Causes — If this condition is encountered, check the following items:

•incorrect CPM board settings

•faulty CPM board

Compressor Unexpected Switch Setting Change

Alarm 132-16 — Circuit A (A1.16)

Alarm 133-16 — Circuit B (B1.16)

Criteria for Trip — The alarm criterion is checked when the compressor is ON. This alarm will be generated if the CPM board S1 setting has changed.

Action to be Taken — The compressor will be stopped.

Reset Method — Manual

Possible Causes — If this condition is encountered, check the following items:

•incorrect CPM board settings

•faulty CPM board

Compressor Power on Reset

Alarm 132-17 — Circuit A (A1.17)

Alarm 133-17 — Circuit B (B1.17)

Criteria for Trip — The alarm criterion is checked when the compressor is ON. This alarm will be generated if the CPM board detects a power failure.

Action to be Taken — The compressor will be stopped.

Reset Method — Manual

Possible Causes — If this condition is encountered, check for power interruptions.

Compressor UL 1998 Critical Section Software Error

Alarm 132-18 — Circuit A (A1.18)

Alarm 133-18 — Circuit B (B1.18)

Criteria for Trip — The alarm criterion is checked when the compressor is ON. This alarm will be generated if the CPM board detects a software error.

Action to be Taken — The compressor will be stopped.

Reset Method — Manual
