14.5 Detailed Functional Description
14.5.1 Activation/Deactivation Logic
Load Management is only active when the generator
system is receiving a system start signal. A generator
does not have to be in AUTO in order to activate Load
Management (but it does to start). The system start
signal can be provided in a variety of ways:
Manual System Start (press AUTO+Run on any
D
controller)
Remote Start Signal (3, 4 contacts)
D
Remote Start via SiteTecht
D
Remote Start via ModbusR
D
Remote Start via CAN
D
Starting a generator in RUN does not cause Load
Management to become active, although it will remain
active with the generator in RUN if receiving a system
start signal. Load Management is not activated when
one or more of the generators in the generator system
are receiving a local start and none are receiving a
remote start.
The generator will receive a local start signal under the
following condition:
Manual Start (pressing RUN on a generator controller
D
to start that generator)
Note: Load Management is deactivated when the
system start signal is removed (even if the
generator continues running because the
individual generator is in RUN mode).

14.5.2 Output Configuration
Although Load Shed notices can be seen in SiteTecht
and on the display of the controller, the load shed notices
only drive external relays (using RDOs or the CAN
option board) if they are configured to do so.
Note: Although each generator has a separate Load
Management system, all Load Management logic
in a paralleling system uses the same power
metering and frequency (bus frequency) to make
Load Management decisions, hence the priorities
are universal between controllers using identical
firmware and Load Management configuration. If
multiple generator controllers exist in the paralleling
system, the Load Management priorities should be
spread between the controllers and not connected
to a single controller — this provides a limited
measure of redundancy.
14.5.3 Startup Shed
Startup Shed occurs when Load Management is
activated. The startup
Decision-Makerr 3500 controller is fixed at 0, meaning
that all load priorities are shed when the Load
Management system is activated.
All loads are added when the Load Management system
is deactivated.
