puls/freq. (frequency output)
Firstly the type of the output (
„Open-Collector“
)
can be selected so that it is suitable for the con‐
nected device (NPN / PNP).
The K factor can be set via the
„signal output“
menu, and is then used by the DulcoFlow
®
to
convert the instantaneous flow prior to output
via the counter output to an external device.
In the
„error output“
menu a setting can be
made to determine whether the DulcoFlow
®
outputs an error signal via the counter output to
an external device. It works like a relay in
status NO.
stroke feedback
For stroke feedback, e.g. to a Prominent
metering pump, as with a Flow Control
®
dosing
monitor, the cable must be fed from the counter
output to the "dosing monitor" terminal of the
metering pump.
Then the
„stroke feedback“
must be calibrated
under
„calibration“
, see chapter "Calibration".
