0...50%. Power controller lower
limit value, referring to generator
nominal power. Lower limit, to
prevent low load running when
running constant power from
mains (peak shaving, option F).
ON/OFF. Selection of external set
point via analog input no. 1
(terminal 93-94).
0/4-20 mA input type celection
Zeropoint and fullscale for
External setpoint.
F = Fixed generator load
B = Power import from mains
(option F only)
L = Power export to mains (option
F only)
ON/OFF. Selection of command
and setpoint settings via RS232
interface (Option D only)
0.5...25.5%. Neutral zone, active
power controller, percentage of
generator nominal power. In paral-
lel with mains, the active power
will be within Pset ±Nz.
1.0...99.9. Amplification factor,
active power controller. The Kp af-
fects the ON time for the relay out-
put. Kp = ON time .
1.0...99.9. After reach of setpoint,
there will be a delay of min. 5 s
before any command pulse is set
i.e. the sensitivity is reduced.
Example: With a Nz of 2.5% and
Sens.red of 2.0, the Nz will, for 5
s, be raised to 5%. After this, if ac-
tual value is within 5%, Nz returns
to 2.5%. This prevents hunting of
the controller.
