Heavy consumer acknowledge
Parameter
Range
Default Comment
Pulse width 1 to 10 s 1 s
The heavy consumer acknowledge digital output is activated for this period.
Delay
0 to 30 s 0 s
The time the controller waits before activating the heavy consumer acknowledge digital output.
If the acknowledge signal is delayed, the generators have time to stabilise the load on the
busbar before the heavy consumer connects.
Configure this parameter under
Configure > Parameters > Heavy consumers > [Heavy consumer #] > Request signal
, where #
is 1 to 4.

Not enabled
Not enabled
: This parameter has no effect on load-dependent stops.
Enabled
: If any heavy consumers are active, load-dependent stops are blocked.
This may lead to inefficient operation. If you only need this function for some
heavy consumers, configure the
Power management > Block load-dependent
stop
digital input function and use it for these heavy consumers.
