Option AU:
A 0-10VDC signal proportional to the flowrate is available with this option.
Max. load 10mA @ 10VDC. (Requires power supply option PD / PF / PM).
Terminal 09-11; 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 09.(unless earthed at
the sensor itself) The maximum input frequency is approximately 10 kHz (depending on the type of
signal). The input signal type has to be selected with the correct SETUP-function (read par. 3.2.3.)
Coil-signal
:
The F131-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 120mV peak to peak.
COIL HI: sensitivity from about 20mV peak to peak.
Option ZF offers for setting COIL HI : sensitivity from about 10mV peak to peak.
Option ZG offers for setting COIL HI : sensitivity from about 5mV peak to peak.
