Criteria for Trip

— The criteria are tested whether the circuit is

ON or OFF. The alarm is generated if one of the following

criteria is met:

1. If the voltage as sensed by the MBB is 0 vdc, which

corresponds to the Navigator™ display of –7 psi

(–48.3 kPa).

2. The circuit is ON in cooling mode and the Saturated

Suction Temperature (

Saturated Suction Temp,

SST

)

for the circuit is greater than the Entering Water Tempera-

ture and EXV opening is less than 50% for more than

60 seconds.

Action to be Taken

— The circuit is shut down immediately, or

not allowed to start.

Reset Method

1. Automatic, once the transducer voltage is greater than

0 vdc, which corresponds to the Navigator display of a

value greater than –7 psi (–48.3 kPa).

2. Automatic once the circuit’s saturated suction tempera-

ture is lower than the Entering Water Temperature by 3° F

(1.6° C). If this criterion trips the alarm 3 times within a

24-hour period, the alarm changes to a manual reset.

Possible Causes

— If this condition is encountered, check the

following items:

• sensor wiring to Main Base Board

• board for a faulty channel

• faulty transducer

• faulty entering water temperature sensor
Reclaim Pumpdown Pressure Transducer
Alarm 32 — Circuit A (Pr.07)

Alarm 33 — Circuit B (Pr.08)
NOTE: Alarms 30 and 31 are not used or supported. If this

condition is encountered, confirm machine configuration.
Oil Pressure Transducer
Alarm 34 — Circuit A (Pr.10)

Alarm 35 — Circuit B (Pr.11)

Criteria for Trip

— The criteria are tested whether the circuit is

ON or OFF. The alarm is generated if one of the following cri-

teria is met:

1. If the voltage as sensed by the CPM board is 0 vdc,

which corresponds to the Navigator display of –7 psi

(–48.3 kPa).

2. The circuit is OFF and outside air temperature is below

35.6 F (2 C).

3. The circuit is OFF and the fluid type is brine.

Action to be Taken

— The circuit is shut down immediately, or

not allowed to start.

Reset Method

— Automatic, once the transducer voltage is

greater than 0 vdc.

Possible Causes

— If this condition is encountered, check the

following items:

• sensor wiring to CPM board

• board for a faulty channel

• faulty transducer

• plugged oil filter

• faulty oil solenoid valve coil

• stuck oil solenoid valve

• confirm unit configuration

Economizer Pressure Transducer Failure (sizes

175,200,350,400 only)
Alarm 37 — Circuit A (Pr. 13)

Alarm 38 — Circuit B (Pr. 14)

Criteria for Trip

— The criteria are tested whether the circuit is

ON or OFF. The alarm is generated if the voltage as sensed by

the MBB or Fan Board C is 0 vdc, which corresponds to the

Navigator display of –7 psi (–48.3 kPa).

Action to be Taken

— The circuit is shut down immediately, or

not allowed to start.

Reset Method

—

Automatic, once the transducer voltage is

greater than 0 vdc, which corresponds to the Navigator display

of a value greater than –7 psi (–48.3 kPa).

Possible Causes

— If this condition is encountered, check the

following items:

• sensor wiring to EXV Board

• EXV board for a faulty channel

• faulty transducer

• faulty economizer EXV or EXV wiring

• faulty economizer EXV channel on the board

• closed or partially closed suction service valve

• confirm unit configuration
Loss of Communication with Compressor Board
Alarm 53 — Compressor Board A (Co.A1)

Alarm 54 — Compressor Board B (Co.B1)

Criteria for Trip

— The alarm criterion is tested whether the

unit is ON or OFF. If communication with the Compressor

Protection Module Board (CPM) is lost for a period of 10 sec-

onds, the alarm will be generated.

Action to be Taken

— The affected compressor will be shut

down.

Reset Method

— Automatic, if communication is established.

If called for, the compressor will start normally.

Possible Causes

— If this condition is encountered, check the

following items:

• power supply to the affected CPM board

• address of the CPM

• local equipment network (LEN) wiring

• confirm unit configuration
Loss of Communication with EXV Board
Alarm 56 — Circuit A, EXV Board 1 (Co.E1)

Alarm 57 — Circuit B, EXV Board 2 (Co.E2)

Criteria for Trip

— The alarm criterion is tested whether the

unit is ON or OFF. If communication with EXV1 or 2 is lost

for a period of 10 seconds, the alarm will be triggered.

Action to be Taken

— If running, Circuit A or B will shut

down normally. If Circuit A or B is not operating, it will not be

allowed to start.

Reset Method

— Automatic, if communication is established,

the unit will start normally.

Possible Causes

— If this condition is encountered, check the

following items:

• power supply to EXV1 or 2

• address of the EXV board

• local equipment network (LEN) wiring

• confirm unit configuration
