Disable Synchronization
The Disable Synchronization parameter allows blocking
the controller from closing the paralleling breaker, but
does not trip the breaker if asserted while the breaker is
closed. This input can be used by external gear to inhibit
the generator from closing to a bus. This allows
integration with existing first-on systems and allows the
generator to be unloaded and tripped without immediate
re-synchronization and breaker closure.
This parameter can be configured to a digital input to
allow it to be controlled by external gear.
Range: False - True
Default: False
Baseload Mode
Baseload Mode is intended for use in parallel with a utility
source. Setting this input to true will place the controller in
baseload mode, which will attempt to control the output
real and reactive power to a setpoint parameter. Only the
controller receiving the baseload mode signal will
operate in baseload, other modes will continue to operate
normally. Baseload mode takes priority over System
Control mode and System Sync mode.
Baseload mode should only be used in parallel with the
utility except as a troubleshooting tool. Baseload Mode
is configurable as a digital input.
Range: False - True
Default: False
System Load Control
System Load Control mode is intended for use in parallel
with a utility source. Setting this input to true will place all
the controllers in the paralleling system in system
control mode (unless baseload mode is also asserted
on the controllers). System control mode controls the
real and reactive power of each generator to targets set
by the external speed and voltage bias, which is 50%
(2.5V equivalent) when the external bias inputs are
disabled. System Load Control mode can be
configurable as a digital input.
Range: False - True
Default: False

System Sync Control
System Sync Control mode is intended for use in
applications where it is necessary to synchronize a
paralleling bus containing multiple generators to a utility
source. System Sync mode causes all generators in a
paralleling system to accept a speed and voltage bias
from the external inputs of a single generator (as long as
external bias is enabled). This allows external gear to
synchronize an entire bus of generators as if it were a
single generator. System Sync Control mode can be
configurable as a digital input.
Range: False - True
Default: False
Enable Trims
Enable Trims allows activating/de-activating of the
frequency and voltage trim functions that are available
while in load sharing mode. There are few applications
where the trims should be disabled, but it provides a
good interface for troubleshooting.
Range: False - True
Default: True
kW Control Mode
Determines the method of controlling generator real power
between the following modes:
Electrical Power Control Mode. The generator
D
controller controls power based on the electrical
power that is produced by the alternator. This is the
normal mode of operation.
Engine Torque Control Mode. The generator
D
controller controls power based on the mechanical
torque as measured or calculated by the engine ECM.
This mode is typically used if one of the generators in
a paralleling system has a mechanical load which is
also coupled to the engine.
Note: Not all applications support this parameter.
Range: Invalid = 0, kWe mode = 1, kWm mode = 2
Default: kWe mode
