Table 7.18 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.

Pulse
Pulse: The heavy consumer request is a pulse signal. The heavy consumer request
cannot be cancelled when the request is a pulse signal.
Continuous: The heavy consumer request is a continuous signal. The heavy consumer
request is cancelled when the request signal becomes low before the delay timer expires
for the Feedback timeout alarm.
Configure this parameter under Configure > Parameters > Power management rules > Configuration # > Load-dependent
start/stop > Heavy consumer, where # is 1 to 8.

Optional: Heavy consumer load-dependent stop
Parameter Range Default Notes
Block stop when
active
Not enabled,
Enabled
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.
