Alarm Functions of the CoolLogic Control System

High Pressure Cutout

This requires resetting at both the module’s manual reset

high pressure control switch and at the Master Control

Panel’s software reset to resume operation (See page 5

(Setup Menu) for Alarm Menu display or press FN+3).

Low Pressure Cutout

This requires resetting at the Master Control Panel to

resume operation (See page 5 (Setup Menu) for Alarm

Menu display or press FN+3).

Compressor Thermal Protector Fault

This would occur if the motor protector sensed an overload

trip in the compressor motor. It would also occur if any

component in the motor protector circuit failed to open.

This requires resetting at the Master Control Panel (See

page 5 (Setup Menu) for Alarm Menu display or press FN+3).

Low Suction Temperature

During operation, should this temperature drop to 28° F, the

compressor will shut down. This requires resetting at the

Master Control Panel after the temperature has risen above

33° F (See page 5 (Setup Menu) for Alarm Menu display or

press FN+3).

High Discharge Temperature (Standard with UCH

and UGW)

During operation, should this temperature rise above 225° F,

the compressor will shut down. This requires resetting at

the Master Control Panel after the temperature has cooled

to below 175° F (See page 5 (Setup Menu) for Alarm Menu

display or press FN+3).

Low Leaving Chilled Water Temperature - Below

38° F

Evaporator freeze protection requires resetting at the

Master Control Panel after the temperature has risen to 40°

F (See page 5 (Setup Menu) for Alarm Menu display or

press FN+3).

High Leaving Condenser Water Temperature -

Above 145° F

This requires resetting at the Master Control Panel after

the temperature has fallen below 140° F. (See page 5 (Setup

Menu) for Alarm Menu display or press FN+3).

Communications Error

This signifies a loss of communication between any module

controller and the Master Control Panel.

Miscellaneous Alarm Functions of the CoolLogic
