11.2 Individual Test Pin Functions
NOTE: Connect the 0V end to the fitting screw on the left of the electronics unit (see Fig. 11.1).
Pin Name
Function
Waveform
FWD
Monitors the amplified output waveform from magnetic
sensor for flow metering.
100μs approx.
300mV min.
300mV min.
REV
Monitors the amplified output waveform from magnetic
sensor for discriminating between FWD and REV flow.
(Only when the double sensor is used.)
Same as above
PLS
Monitors the rectangular waveform after FWD pulsee
waveshaping. Timing remains the same as that of FWD and
its waveform is one before unfactored output amplification.
2ms approx.
3V app.
IN
Accepts a simulated pulse train OVAL pulse checker Model
PC2201, or other signal source.
Input mode is PG30 mode of Model PC2201. It also accepts
pulses with levels "0": 1V max. and "1": 7 to 12V min. or
open collector.
