Connecting the sensor
Connecting the signal and magnet coil cables
The flowmeter sensor is connected to the transmitter via the signal / magnet coil cables (part no. D173D025U01 / D173D147U01). The
coils of the flowmeter sensor are supplied with a field voltage by the transmitter over terminals M1/M3. Connect the cables to the
sensor in accordance with the following drawing, using a screwdriver with proper size and width.
