4.9 Port for the transducer
Funktion DescriptionReference voltage P24 VDC +
Reference voltage L VDC -
Transducer signal OI 4-20mA
Caution!
Use shielded cable and connected to the grounding clamps in the cabinet!
Note terminal assignment (see the sensor Type plate)!
4.10 Port for the motor / pump
Clamp Function Description
U3 phase motor U1
Vsee the V1
WType plate W1
Caution!
Motors must be connected corresponding the output voltage (230V or 400V): Star- or Delta- connection
(motor terminal board)! Output voltage = input voltage.
4.11 Port for the motor / pump: single Phase
Clamp Function Description
U3 phase motor U1
Vsee the V1
Caution!
Verify the correct connection of the network, transducer, and control lines.
Check before switching on the mains again all connections are correct!
