7.10 Pulse outputs
(either pulse outputs or pulse inputs on F2)
F2 can be equipped with two pulse outputs as standard of the type “Open collector” for
energy (pulse output 1) and volume (pulse output 2).
The last digit and the energy unit will reveal the pulse weight of the pulses. Example:
sequence “10” (energy) on display is shown “1001.01” MWh => pulse weight = 0.01
MWh/pulse.
Pulse output 1
Energy; one (1) pulse for each update of the last digit in the energy register (seq. “10”).
Pulse output 2
Volume, one (1) pulse for each update of the last digit in the flow register (seq. “11”).

7.11 Pulse inputs
(either pulse outputs or pulse inputs on F2)
F2 is equipped with two pulse inputs as standard. The pulse inputs can be
used for measuring of other meter with pulse outputs, such as cold and hot
water meters, gas, electricity meters and other meters. The pulse inputs can
be set as volume registers. These registers accumulate the pulses into two
volume registers with the value [m3].

7.12 Alarm output
The F2 is equipped with one alarm output as standard of the type “Open collector”. The
alarm output sends a pulse every hour as long as an error code exists. The pulse duration
250 [ms] for pulse and alarm output can be altered using the “Service program” version
2 or higher in 125 [ms] steps.
