Parameter Explanation
Setpoint
pressure
Setpoint pressure can be regulated to two values: pA and pB
Setting:
■ Switching point pA or control pressure pA in machines with frequency converter
(SFC)
■ Switching point pB or control pressure pB in machines with frequency converter
(SFC)
System
pressure low
A warning message is displayed when the limit value for the system pressure is
reached.
Setting:
■ SD: Switching differential for system pressure low,
SP: Switching point for system pressure low
■ Option: Configure the output signal,
