Notes:
1.
Connections for Motor Temp, Discharge Temp, and echelon communications are all polarity insensitive.
2.
L1 must be jumpered to 240V or 120V depending on line voltage. The drawing shows wiring for 120V. The L1
input is used to power the alarm output.
3.
The compressor is loaded when the solenoid is energized and unloaded when de-energized.
4.
A normally closed set of contacts can be added to reset power to the module. Useful for remotely resetting a
module out on an Alarm Failure
5.
The diagnostic alarm code is flashed by the yellow alarm light during a compressor alarm.
6.
The system safeties are monitored on the Slimits Input. This input actually powers the contactor output and is
switched through the module. See section 1.2 for details on the additional required system safeties.
7.
A voltage sensing relay (VSR) (or an equivalent method) should be used to detect if power is lost to the line side of
the contactor (i.e. circuit breaker has tripped).
