3.32. Heuristic power control
Heuristic mode allows for the device to synchronize out-
puts within the device to maintain a more steady usage of
power. Heuristic mode that is not enabled could result in all
outputs being turned on(full conduction) at the same time,
or conversely all off at the same time. With Heuristic mode
the user will set a maximum current limit and the device will
manage outputs based upon this maximum current.
Heuristic mode helps limit peak power demands within the
device. While in heuristic mode the power control will de-
termine the most appropriate output combinations to stay
under maximum power applied to load.

The parameter enables the heuristic power control of GPC-M, GPC-E1 and GPC-E2. Setting hd.3 = 0 disables heuristic power control for
all modules.
Enabling only applies to GPCs with OUT1...OUT3 outputs with slow cycle time (1...200 seconds).

This function only works with the GPC-3PH models that are
controlling 3 single phase lines in on-off modulation (zero
cross modes).
Gefran has products that has the ability to manage peak
power demands across the entire plant floor. See Gefran
model GSLM, Smart Load Management.
