Compressor Phase Loss

Alarm 132-06 — Circuit A L1 (A1.06)

Alarm 133-06 — Circuit B L1 (B1.06)

Alarm 132-07 — Circuit A L2 (A1.07)

Alarm 133-07 — Circuit B L2 (B1.07)

Alarm 132-08 — Circuit A L3 (A1.08)

Alarm 133-08 — Circuit B L3 (B1.08)

Criteria for Trip — The alarm criteria are checked during

startup when the compressor is ON. This alarm will be gener-

ated if:

• The current unbalance on any of the 3 phases is greater than

48% for more than 1 second continuously during start-up.

• The current unbalance on any of the 3 phases is greater than

48% for more than 2 seconds continuously during runtime.

Action to be Taken — The compressor will be stopped.

Reset Method — Manual

Possible Causes — If this condition is encountered, check the

following items:

• power failure

• blown fuse or tripped circuit breaker

• power wiring errors or loose terminals

Compressor Low Current

Alarm 132-09 — Circuit A (A1.09)

Alarm 133-09 — Circuit B (B1.09)

Criteria for Trip — The alarm criteria are checked when the

compressor is ON. This alarm will be generated if:

• The current is less than 15% MTA on all three legs for more

than 1 second for wye-delta start units.

• If the current is less than 15% of MTA on all three legs for

more than 1 second for direct start units.

Action to be Taken — The compressor will be stopped.

Reset Method — Manual

Possible Causes — If this condition is encountered, check the

following items:

• power failure

• blown fuse or tripped circuit breaker

• deenergized contactor

• faulty current toroid

• high pressure switch (HPS) trip (when auto reset HPS is

used)

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 shutdown. 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)
