Paralleling Parameters - Kohler 14EKOZD Installation Manual

all the generators are stopped. The generator with the
most fuel will be started first.
Because a generator will not be consuming fuel when it
is stopped, it is necessary to add a stability threshold to
each generator which is not running or the generators
will start as soon as 1% of the running generator's fuel is
consumed. This threshold is called the Generator
Management Fuel Level Threshold.
Configure the threshold to allow the generators to
equalize run time without starting and stopping each
generator unnecessarily. The factory default is 10% of
fuel level—one of the running generators will have to
have 10% less fuel than the generator that is stopped
before the generator will start. Once that generator is
online, the generator with the least fuel will stop.

Paralleling Parameters

Generator Management Enabled
Set this to true if Generator Management is desired for
this application
Generator Management Stability Delay
The Stability Delay is intended to ensure that all loads
have returned to their normal demand before Generator
Management considers stopping a generator.
All generators will be told to run until the Stability Delay
has expired.
Generator Management Minimum Gens Online
The Minimum Gens Online parameter will allow the
system to be configured to require at least 1 generator or
to require at least 2 generators. If set to 2 Generators,
the system will always keep one more generator online
than is required.
Note: The default setting is 2.
Generator Management Min Load Shed Priority
The Minimum Load Shed Priority is the priority which
has to be online to allow Generator management to
become active (start the stability timer). This parameter
should match the maximum load shed priority that is
connected to an actual load.
The default setting is 6 (load priority 6 must be online
before generator management becomes active).

Generator Start Percentage
The Generator Start Percentage is the percent load on
the running generators above which this generator will
begin timing for the Generator Start Delay.
The default setting is 80%, this means that the other
generators will have more than 80% load on them before
this generator will begin timing for the Generator Start
Delay.
Generator Stop Percentage
The Generator Stop Percentage is the percent load on
the other running generators below which this generator
will begin timing for the Generator Stop Delay. The Stop
percentage is calculated as if this generator was not
running (the percent load on the remaining generators).
The default setting is 60%, this means that the total load
on all the running generators is low enough that all the
running generators other than this one will have less
than 60% load on them if they were supporting the load.
The order 1 generator does not stop.
Generator Start kW
The Generator Start kW is calculated based on the Start
kWs of each of the generators with a lower order number
and the Start percentage for this generator. The Start kW
is the total load on the bus above which this generator will
begin timing for the Generator Start Delay.
Generator Stop kW
The Generator Stop kW is calculated based on the Stop
kWs of each of the generators with a lower order number
and the Stop percentage for this generator. The Stop kW
is the total load on the bus below which this generator
will begin timing for the Generator Stop Delay.
Generator Start Delay
The Generator Start Delay is the time delay in seconds
for this generator to start. Because the start delay is
actually a curve based on the difference between the
actual kW and the start kW of this generator, the start
delay is actually the time for the generator to start with a
10% overload.
Generator Stop Delay
The Generator Stop Delay is the time delay in seconds
for this generator to stop. Because the stop delay is
actually a curve based on the difference between the
actual kW and the stop kW of this generator, the start
delay is actually the time for the generator to start with
10% less load than the stop kW.
