Voltage Selector Switch; Paralleling Operation - Kohler 14EKOZD Operation

The user can change the individual value or can select Reset Regulator Defaults?-Yes to reset to the default value. The Reset
Regulator Defaults display will only show if editing is enabled.
Start-Up Ramp Rate. Slowly ramps the voltage to its target to minimize voltage overshoot at startup.

2.11.5 Voltage Selector Switch

The voltage selector switch menu does not apply to the EKOZD and EFKOZD models.

2.11.6 Paralleling Operation

Note:
Have paralleling setup performed by appropriately skilled and suitably trained maintenance personnel familiar with generator set
parallel commissioning, operation, service, and troubleshooting.
®
The Decision-Maker 3500 controller is a paralleling controller and provides varying degrees of paralleling functionality.
®
While the Decision-Maker 3500 controller can also be used with external switchgear controlling the speed, voltage and
paralleling breaker/contactor, the Parallel Operation menu is used to configure settings for parallel operation where the controller
is communicating on a network with other controllers and provides integral paralleling functionality.
Paralleling Setup
The Paralleling Setup menu is intended to configure the basic settings for the parallel operation of the controller. Most of the
settings in this menu are configured during commissioning and do not require user adjustment. There are a few settings that
may be viewed or adjusted after commissioning is complete.
Volts-Hz OK Delay. The time that the voltage and frequency must remain within the acceptable window before the controller
considers them to be stable. The voltage window requires the output voltage of the generator to be within the Voltage OK
Pickup of the system voltage, the frequency window requires the operating frequency of the generator to be within the
Frequency OK Pickup of the system frequency. This delay may need to be increased if the first generator to close to the bus
has not yet reached rated operating parameters or if the speed/voltage is in an overshoot condition when the generator comes
online.
First On Delay. The time that the system will wait before closing the first generator to the bus. This delay should be set as low
as possible, but can be extended to ensure that a different generator will be the first to close. One generator in the system should
have the first on delay set to a low number to minimize the delay before the generator can supply power to the load.
kW Ramp Rate. The generator will load and unload against the other generators at this rate. The default rate (5%/sec) requires
20 sec to accept 100% load. Increasing the ramp rate will allow the generator to disconnect more quickly from the bus when
signal to stop by generator management, but may result in variations in the output voltage or frequency of the generator system.
The ramp rate can be decreased if there is noticeable fluctuation in the voltage or frequency when a generator is loading or
unloading.
Trims Enable. The trims are the mechanism that the paralleling system uses to keep the output voltage and frequency near the
rated values when the generator system is operating. The trims default is enabled on all generators, but they can be disabled
on some generators in the system to improve load sharing. The trims should be enabled on at least one generator in the
paralleling system or the voltage and frequency may drift significantly during the operation of the system.
Load Enable. The generator will unload and trip the circuit breaker/contactor when this setting is set to OFF. This can be used
to force a generator to soft-unload and shut down for service. To keep the breaker/contactor from reclosing, the Sync Mode in
Auto can be set to OFF (see Sync Mode In Auto below). A generator is not considered for generator management when Load
Enable is set to OFF. This parameter should always be returned to ON after the generator has been stopped for service, as it
will keep the generator from sharing load or starting for generator management if it is set to OFF.
Stand Alone Mode. This will tell the controller that it is a paralleling controller, even if it does not see another generator on the
communication lines. This may be required if all other generator controllers are removed from service for a period of time in
which the battery power to this controller will be cycled (the controller remembers that it is in a paralleling system until power is
cycled). If the controller sees another controller on the PGEN communication network, this parameter will not change the
operation of the system in any way.
Sync Mode In Auto. This should be set to Active before leaving the vessel when commissioning or testing is complete, but can
be used to keep the controller from closing the paralleling breaker/contactor to complete a test or to take a generator out of
service. Setting the Sync Mode to OFF will disable the synchronizer, the paralleling breaker/contactor will not close with the
