Compressor On

 

The Compressor On light turns on whenever the

 

 

 

 

 

 

 

 

 

 

 

 

 

Light

 

compressor is operating.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Low Temperature

The Low Temperature light comes on if the process

 

 

 

 

 

 

Light

water/glycol temperature drops below the High/Low

 

 

 

 

 

 

 

thermostat set point. The Low thermostat stage one

 

 

 

 

 

 

 

switch opens the control circuit shutting down the

 

 

 

 

 

 

 

compressor, but the process water/glycol pump(s)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

continue to operate. This action prevents possible

 

 

 

 

 

 

 

chiller evaporator freeze-up.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Hot Gas Bypass

 

The Hot Gas By-Pass light turns on when the hot

 

 

 

 

 

 

Light

 

gas bypass valve is in operation. The OUT1 LED on

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

the controller also lights when the hot gas bypass

 

 

 

 

 

 

 

 

valve is in operation.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

High Temperature

 

The High Temperature light comes on if the process

 

 

 

 

 

 

Light

 

water/glycol temperature rises above the High/Low

 

 

 

 

 

 

 

 

thermostat stage two set point. The High thermostat

 

 

 

 

 

 

 

 

stage two switch opens the control circuit shutting

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

down the process water/glycol pump(s), and the

 

 

 

 

 

 

 

 

chiller shuts off. This action prevents possible

 

 

 

 

 

 

 

 

system failure from overheating of the process

 

 

 

 

 

 

 

 

water/glycol.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Pump On Light

The Pump On light, installed on chillers with a

 

 

 

 

 

 

 

 

 

 

 

 

 

 

pump, lights whenever the pump(s) operates.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

High Discharge

 

The High Discharge Temperature light comes on if

 

 

 

 

 

 

Temperature Light

 

the compressor discharge line temperature switch

 

 

 

 

 

 

 

 

opens. This switch prevents possible compressor

 

 

 

 

 

 

 

 

failure due to over loading, the compressor stops,

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

but the pump(s) continue to run. This occurs when

 

 

 

 

 

 

 

 

the discharge line temperature rises above 260ºF

 

 

 

 

 

 

 

 

(127ºC). Call a qualified refrigeration service

 

 

 

 

 

 

 

 

technician or contact the Service Department.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Pump Overload

 

The Pump Overload light, installed on chillers with

 

 

 

 

 

 

Light

 

a pump(s), lights whenever a pump motor(s) has

 

 

 

 

 

 

 

 

shut down from a motor overload condition.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

High Refrigerant

 

The High Refrigerant Pressure light comes on if the

 

 

 

 

 

 

Pressure Light

 

compressor discharge pressure exceeds the limit of

 

 

 

 

 

 

 

 

the high pressure cutout switch. The compressor

 

 

 

 

 

 

 

 

stops but the pump(s) continue to run until you

 

 

 

 

 

 

 

 

manually reset the high-pressure cutout switch. Call

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

a qualified refrigeration service technician or

 

 

 

 

 

 

 

 

contact the Service Department.
