6.3.6 Pulse output
By default two pulse outputs A and B are available. Optionally, status output 1 is available as a
third pulse output C. Pulse output A and B are fiscal parameters, pulse output C is not a fiscal
parameter.
The relation between pulse output A and B can be set in menu number 22 to the following pre-
sets:
There is a phase shift of 90° offset between pulse output A and B. Pulse output A and B give the
same number of pulses, but pulse output B is shifted half a pulse width in time. In case of
forward flow, pulse output B runs behind pulse output A. In case of reverse flow, pulse output A
runs behind pulse output B.
If after a phase shift (90°) pulse output A runs behind pulse output B, the number of pulses need
to be subtracted from the total, to get the net volume, equal to the sum counter on the display.
Pulse output A gives the forward volume and pulse output B gives the reverse volume passing
through the meter.
For a net volume, equal to the sum counter on the display, the pulses provided by pulse output B
need to be subtracted from the pulses provided by pulse output A.
Pulse output A and B; 90° offset (default value)
1 Forward flow
2 Reverse flow
Pulse output A and B; Forward - Reverse
