Terminals 5-7; Flowmeter input:
Three basic types of flowmeter signals can be connected to the unit: pulse, active pulse or coil. The
screen of the signal wire must be connected to the common ground terminal
The input signal type has to be selected with the correct SETUP-function (read par. 3.2.3.)
Coil-signal:
The F012-P is suitable for use with flowmeters which have a coil output signal.
Two sensitivity levels can be selected with the SETUP-function:
COIL LO: sensitivity from about 90mVp-p.
COIL HI: sensitivity from about 20mVp-p.
Type ZF (option): offers for setting COIL HI : sensitivity from about 10mVp-p.
Type ZG (option): offers for setting COIL HI : sensitivity from about 5mVp-p.
