2.1 MagMaster Sensor Cable Wiring to WaterMaster Transmitter
Check the wiring of the sensor cable carefully to ensure good, clean connections. Ensure there are no stray
strands of wire and all terminals are tight.
Fig. 2.1 Shows the wiring of the sensor cable to the remote WaterMaster electronics.
2.1.1 Sensor Coil Resistance
WaterMaster transmitter requires a minimum sensor coil resistance of 15
for correct operation. The coil
resistance can be measured between M1 and M2 with the meter turned off.

Caution.
Do NOT reverse the inner / signal [E1, E2] and outer / screen [S1, S2] cores of the coaxial cables.
Ensure the black anti-microphonic layer in the grey and white screened cables is removed.
Note.
An alarm on the WaterMaster display indicates if the coil resistance is too low for the WaterMaster
transmitter to operate. For the MF/F flowmeter sensor this alarm should not occur. Contact ABB Service
if it does.
