4.4 Minimum HP Pump Inlet Pressure (PSI):
This value determines at what minimum inlet pressure the system will shut down and indicate a High
Pressure pump inlet pressure low fault. In order for the Danfoss high pressure pump to operate
correctly there must always be a minimum inlet pressure of 20 PSI at the inlet of the pump, pressure
below this limit cause the pump to cavitate, if the control system is connected to a CAT pump this value
can be much lower.
Typical values entered here are 20 PSI in Danfoss pump applications
Typical values entered here are 10 PSI in CAT pump applications
4.5 Maximum HP Pump Inlet Pressure (PSI):
This value determines at what maximum inlet pressure the system will shut down and indicate a High
Pressure pump inlet pressure high fault. In order for the Danfoss high pressure pump to operate
correctly there cannot be a pressure greater than 75 PSI at the inlet of the pump, pressure above this
limit causes the pump to shear off the piston shoes as it initially begins to rotate. This type of damage is
not covered by warranty should these settings report being changed by the user, if the control system is
connected to a CAT pump this value should remain at 75 PSI.
Typical values entered here are 75 PSI in all pump applications
4.6 System Minimum Operating Pressure (PSI):
This value determines at what minimum outlet pressure the system will allow the high pressure pump to
operate for extended periods of time. Operation below the inputted value triggers an alarm, and after
10 minutes a total system shutdown. Setting this value too low can severely damage the high pressure
pump, as there is not enough internal pressure to lift the piston shoes off the pump back plate. This
causes rapid wear of the piston shoes and eventual failure of the pump. This type of damage is not
covered by warranty should these settings report being changed by the user, if the control system is
connected to a CAT pump this value can be reduced
Typical values entered here are 350 PSI in Danfoss pump applications
Typical values entered here are 100 PSI in CAT pump applications
