transducer or a short circuit in the wiring. In this condition, it is also possible for the analog input to be
damaged. This can happen if the transducer fails shorted or is connected improperly.
SucPrsFail = Suction Pressure transducer failure (same as for DisPrsFail - Discharge Pressure transducer failure)
Indicates that the value read from the transducer is outside of the expected range.
• If the value is negative, this indicates an open circuit in the wiring to the transducer.
• A high positive value indicates a failed transducer or improper wiring.
The transducer is a 3 wire ratiometric device. It receives +5VDC power from the compressor control module.
It provides an output signal between 0.5 and 4.5 VDC for the rated pressure range of the transducer.
LowPress = Low refrigerant Pressure condition has occurred
The controller detected a lower than expected suction pressure.
This is detected by either the pressure transducer and/or the “loss of charge” low pressure switch.
Please contact PoolPak Service for assistance in troubleshooting this fault condition.
MotorTmp = Compressor Temperature failure
The controller detected an alarm signal from the compressor protection module.
This module is located in the terminal box of the compressor. It provides an alarm signal when the compressor’s
motor winding temperature is too high or when the power supply to the compressor is incorrect in voltage or
phase rotation.
Please contact PoolPak Service for assistance in troubleshooting this fault condition.
HighPress = High refrigerant Pressure condition has occurred
The controller detected a higher than expected discharge pressure.
• This is detected by either the pressure transducer and/or the high pressure cutout switch.
• The controller also detects this condition if there is no current to the compressor when it should be running.
Please contact PoolPak® Service for assistance in troubleshooting this fault condition.
