terminal plate to the motor temperature inputs on the LonCEM module. In the event of a
thermistor failure, a spare thermistor is available between S2 and S3.
Sensor Operating Range
The table shown below shows the allowable operating range for each of the sensor inputs.
Values measured outside these limits will result in a sensor failure alarm. See Appendix
D for a summary of the sensor alarm codes. The inputs are verified both when the
compressor is on and off.
Sensor Inputs
Suction Pressure Transducer
Discharge Pressure Transducer
Oil Pressure Transducer
Motor Temp Thermistor
Discharge Temp Thermistor
3.3 Control Outputs
Each of the module outputs is summarized below. Note that each of the corresponding
liquid LED lights (one for each output) is lit whenever the output is closed and the output
is energized. See Table 2 for a summary of the module temperature control functions.
1CR Contactor
This terminal supplies power to the compressor contactor coil/relay. The module uses
this output to turn the compressor on or off. Whenever power is supplied to Ccall
(compressor call input), 1CR is closed pulling in the contactor and starting the
compressor. A 20 second time delay between compressor starts is built into the module.
The time delay is active at initial module power-up, or whenever the compressor is called
for before 20 seconds of off-time has elapsed.
2CR Part Wind Contactor
Supplies power to the compressor part-wind contactor coil/relay, if part-wind start is
used. This output is automatically energized 1 second after 1CR during start-up.
Liq M Liquid Injection (initialized for Motor Cooling)
Energized whenever the motor temperature limit is exceeded (see Table 2). This output
is closed energizing the motor cooling valve and injecting liquid refrigerant into the motor
compartment.
Liq D Liquid Injection (initialized for Discharge Temperature)
