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

The values in the table for the maximum number
of pulses per hour result from the minimum pulse
length and the minimum pulse pause.

INFORMATION
The pulse interval is proportional to the power
within the selected settings.
INFORMATION
When programming with GridVis®, you are giv-
en a selection of work values derived from the
power values (see www.janitza.com).
Pulse valency
The pulse valency specifies how much energy
(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, the device only sends
pulses when electrical energy is consumed.
INFORMATION
Since the reactive energy meter operates with
a reverse running stop, the device only sends
pulses when there is an inductive load.
