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.
