Minimum pulse length (Add 010)
The minimum pulse length can be adjusted in
10ms steps within a range from 50ms up to
1000ms. The shortest interpulse period equals
the programmed minimum pulse length.
For a minimum pulse length of 50ms, the maxi-
mum pulse frequency is 10Hz. If fewer pulses
have to be output the interpulse period is
lengthened. The pre-programmed minimum
pulse length, e.g. 50ms remains constant.
Important!
As the active power demand counter op-
erates with a
return block
, pulses are
only output during the imported supply of
electrical power.
As the
reactive power demand counter
operates with a
return block
, pulses are
only output during an inductive load.
Important!
The pulse intervals are
not
proportional
to the power output.

Pulse value
The pulse value denotes how much work
(power demand - Wh or kvarh) a pulse equals.
The pulse value must not be confused with the
meter constant. The meter constant is given in
Meter constant = revolutions per kWh
.
The relationship between pulse value and me-
ter constant can be seen in the following equa-
tions:
Meter constant = 1 / pulse value
Pulse value = 1 / meter constant
