3.2.2 Closed loop control redundant: differential pressure with PumpMeter (Modbus)
Etaline Z double pump (2x100%): A constant differential pressure of 4 bar is needed. PumpMeter is used as a differential pressure sensor
in the measurement range of -1 … 10 bar. PumpMeter is connected by Modbus to the M12 Module of the drive. The sensor signal of
PumpMeter is linked by a cross link cable (see accessories) from drive to drive. The AuxMaster can take over control if the Master fails.
The set point is given by the display. Pump changeover will take place regularly after 24 hours of operation.
