6.4.10 TERMINALS S1-S3: FLOWMETER INPUT
Three basic types of flowmeter signals can be connected to the unit: pulse, active pulse or sine-
wave (coil). The screen of the signal wire must be connected to the common ground terminal (unless
earthed at the sensor itself).
The sensor output should match with the selected flowmeter setting of
SETUP
5: FLOWMETER[»25].
Sine-wave signal (Coil)
The unit can be used with flowmeters which have a coil output signal. Two sensitivity levels can be
selected (see
SETUP
5: FLOWMETER[»25]):
● COIL LO: sensitivity 90 mVpp.
● COIL HI: sensitivity 20 mVpp. (with Type ZF: 10 mVpp; with Type ZG: 5 mVpp).
