High Motor Amperage If the amperage analog input rises above the value of the compressor’s respective FLA Setpoint #171 – 190 times the value of Setpoint #75 or the digital input turns ON for the time specified in the Time (sec)’ field, then the circuit will be Locked Out and a HIGH MOTOR AMP alarm generated. Refer to section 11 Setpoint #75. - Page 23 Cavity Temperature Fault (Hex code =0x0020) The measured Cavity Temperature has exceeded either the Alarm or Fault limit, probably due to insufficient motor cooling (shaft cavity). Leaving Fluid Temperature Fault (Hex code =0x0040) The measured Air / Water Temperature has exceeded either the Alarm or Fault limit, probably due to insufficient air / water flow. Pressure Ratio Fault (Hex code =0x0080) The measured Compression Ratio of Discharge and Suction has exceeded either the Alarm or Fault limit, probably due to faulty condenser or insufficient load on the evaporator.
- Page 24 Winding Temperature Fault (Hex code =0x1000) The measured motor winding temperature has exceeded 155ºC. Superheat Fault (Hex code =0x2000) The Fault limit is based on the suction pressure and temperature values. There is no time delay on this fault or alarm. The difference between the fault limit and alarm limit is the dead band for the control.
