Table 6: ALARMS Setpoint Settings
Description No . Default Range Password Comments
Condenser Freeze Protect 11 34.0 °F -9.0 to 45.0 °F T Minimum condenser saturated temperature to start pump
Evaporator Freeze Protect 10 34.0 °F -9.0 to 45.0 °F T Minimum evaporator saturated temperature to start pump
Motor Current Threshold 9 10% 1 to 20% T Min %RLA to consider that the is motor off
Surge Slope Limit 8 20 °F/min 1 to 99 deg F/min T
Surge temperature (ST) slope value above which alarm occurs.
Active only if ST>SP7 at start
Surge Temperature Limit 7 50 °F 2 to 45 °F T At start, Surge Temp (ST) is compared to this SP. Alarm at ST>2x SP.
High Discharge Temp-Stop 6 190 °F 120 to 240 °F T Max discharge temp to shut down compressor
High Discharge Temp-Load 5 170 °F 120 to 240 °F T Sets discharge temp above which a forced capacity increase occurs
High Condenser Pressure 4 140 psi 120 to 240 psi T Max discharge pressure, stop compressor
Low Evap Pressure, Stop 3 26 psi 10 to 45 psi T Min evap pressure – stop compressor
Low Evap Pressure-Unload 2 31 psi 20 to 45 psi T Min evap pressure – unload compressor
Low Evap Pressure-Inhibit 1 33 psi 20 to 45 psi T Min evap pressure – inhibit loading
