NOTE:
The electrical connection of the differential pressure sensor is to be
fed through the smallest threaded cable connection (M12) on the
module.
For a double pump or Y-pump installation, the differential pressure
sensor is to be connected to the master pump.
The measuring points of the differential pressure sensor of the master
pump must be on the suction and pressure side of the double-pump
system in the corresponding collector pipe.
• Establish connections observing the terminal allocation.
• Ground the pump/system according to regulations.
The electronics module is operated using the following operating ele-
