Pulse output

The meter is equipped with an optical interface in accordance with EN 62056-
21:2002 as standard.
Note: You can find further information in their respective documen-
tation.
If the meter is equipped with the option M-Bus, it is supplied with a 2-wire ca-
ble which you can extend by fitting a junction box.

Reading interval
Power supply
The pulse exit permits the output of pulses that can be derived from the ener-
gy, the volume or the error status.
Two channels are available whose functions can be parameterized with the
service software or who can be adapted in "Para menu" of the meter.
Output takes the form of standard pulses or as "high-definition pulses".
The pulse duration is identical for channel 1 and channel 2.
