14.3 Considerations
Load Management is not required or desired in all
applications. Although it is active any time that the
generator is receiving a system start signal, it must be
configured and connected to be used. It is important to
consider the following when using Load Management:
14.3.1 Total Load on the System
If the power requirements of the load will never exceed
the capacity of the generator, there is no need or reason
to connect and configure Load Management for the
application. If the load is high enough to overload a
single generator or one of the generators in a paralleling
system, it should be prioritized and connected to Load
Management controls.
14.3.2 Load Types
Applications where the loads are occasional will allow
for generator capacity below the sum of all connected
loads, but the generator can be overloaded if all the
occasional loads were
simultaneously.
14.3.3 Ease of Interrupting Loads
Many loads are easily controlled with a simple relay
(such as HVAC systems, VFDs and Soft Starters), such
loads can be tied to Load Management outputs with very
little difficulty and will allow temporary power
interruptions without serious loss of function.

14.3.4 Criticality of the Loads
The generator must be sized to support at least the
critical loads in the application. A generator that is able
to support the critical loads may be significantly smaller
than the entire load requires.
Some applications have loads that can be easily
categorized and prioritized. In this case, Load
Management would be helpful to prevent loss of power
to critical loads. If all loads are of similar importance,
Load Management will be difficult to apply.
14.3.5 Number of Generators in the
System
Multi-generator systems should typically utilize Load
Management unless they have multiple generators
simply for redundancy (any generator can handle the
entire load).
14.3.6 Use of Generator Management
If Generator Management
Management outputs should be connected to some
loads to allow an additional generator time to start if the
load increases suddenly past the level that the running
generators can support.
14.3.7 Emissions Requirements
Some facilities require minimum load while operating.
The Load Management can also be used to control loads
on a load bank, maintaining the generator at or above a
given load level. Other application require the generator
to undergo a de-rate for a DPF regeneration cycle.
