Pulse length
The pulse length applies for both pulse outputs
and is set via the GridVis® software.
The typical pulse length for S0 pulses is 30 ms.
Pulse pause
The pulse pause is at least as large as the select-
ed pulse length.
The pulse pause depends on the measured ener-
gy, for example, and can be hours or days.

The maximum number of pulses per hour is
calculated based on the minimum pulse duration
and the minimum pulse pause, resulting in the
values in the table.

INFORMATION
The pulse interval is proportional to the power
within the selected settings.
INFORMATION
When programming with the GridVis® software,
you are given a selection of work values that
are derived from the power values (see www.
janitza.com).
Pulse valency
Use the pulse valency to specify how much ener-
gy (Wh or varh) should correspond to one pulse.
The pulse valency is determined by the maximum
connected load and the maximum number of
pulses per hour.
If you indicate the pulse valency with:
·With a positive sign, pulses are only output if the
measured value also has a positive sign.
·With a negative sign, pulses are only output if the
measured value also has a negative sign.
INFORMATION
Since the active energy meter operates with a
reverse running stop, pulses are only output
when electrical energy is consumed.
INFORMATION
Since the reactive energy meter operates with
a reverse running stop, pulses are only output
when there is an inductive load.
