WSCM SAFETY FEATURES
CONDENSATE OVERFLOW SENSOR
The condensate overflow sensor must sense overflow
levels for 30 continuous second to initiate a COF fault. The
condensate overflow sensor will be monitored during the
compressor run cycle.
LOW PRESSURE
The low pressure switch must be open and remain open for
30 continuous seconds during the “on” cycle to be
recognized as a low pressure fault. The low pressure switch
input is bypassed for the initial 120s of compressor run-
time.
HIGH PRESSURE
If the high-pressure switch opens at any time, the
compressor relay is de-energized immediately.
LOCKOUT MODE
While in Lockout Mode the LED Display will display a code
representing the lockout fault code. During this lockout the
compressor relay is not energized and the alarm relay is
activated.
The lockout mode can be cleared by either going into test
mode or a hard reset via the power disconnect
Caution: Do not restart units in lockout mode without
inspection and correction of the fault condition. Failure to
do so many result in equipment damage.
EXTENDED COMPRESSOR OPERATION MONITORING
If the compressor relay has been energized for four
continuous hours, control module will automatically turn
off the compressor relay and the compressor will enter
anti-short cycle delay before restarting. During this off
period, all appropriate safety will be monitored and if the
compressor demand is present, the control module will
energize the compressor relay.
OVER/UNDER VOLTAGE SHUTDOWN
Should an Over/Under Voltage Condition be detected the
control module will shut down. Over/Under Voltage faults
cause a soft lockout and the unit will return to normal
operation once normal voltage has been restored. The
nominal voltage run is 18.5VAC to 31VAC. If the WSCM
module is in Over/Under Voltage fault for 15 minutes, the
alarm relay will activate.
