Select 2
nd
Dynamics
One of the 3 configurable discrete contacts can be configured as Select 2
nd
dynamics. In menu I**Dynamics #2** the parameter enable dynamics 2 w/CB should
be configured at TRUE to enable the 2
nd
dynamics. This contact can be connected to
a clutch-feedback or when a different operating mode of the engine is used to
activate the 2
nd
dynamics, when a separate set of PID settings are necessary.
Shutdown Internal
There are six shutdowns that can affect the fuel demand of the actuator output:
Overspeed
MPU Fail
Analog Input #1 Fail
Analog Input #2 Fail
Test Mode
External Shutdown
Any internal shutdown will cause the fuel demand to go to 0% on a forward-
acting actuator. On a reverse-acting actuator, any internal shutdown will cause
the fuel demand to go to 100%. This will cause the mechanical backup flyball
governor to take control.
To reset an internal shutdown, the reset can be given by a reset input if
configured, or the Run/Minimum Fuel contact 31 should be toggled. After a
shutdown has occurred (for example an overspeed or an MPU failure), you can
only reset the control when the engine speed is zero.
Shutdown External
One of the 3 configurable discrete contacts can be configured as External
shutdown. When the contact is open, the control operates normally, Closing the
contact will cause the engine to go to 0% fuel demand on a forward-acting
actuator, and 100% fuel demand on a reverse-acting actuator. Reverse-acting
actuators should always contain a mechanical ballhead governor. When the
contact is opened again, a reset should be given before the engine can be
started again. The reset can be given by a reset input if configured, or the
Run/Minimum Fuel contact 31 should be toggled.
Rated Speed
The external contact used to activate the Rated Speed command connects to
terminal 33 (default). This discrete input changes the control operation by
increasing the speed reference to RATED SPEED and decreasing the speed
reference to IDLE SPEED. When the switch or relay contacts are closed, the
speed reference will ramp for a time set by the Accel Time to the rated speed
control point. When the switch or relay contacts are open, the speed reference
will ramp for a time set by the Decel Time to the idle speed control point. The Idle
Speed function is disabled by internal logic when the generator breaker is closed.
The Rated Speed input should be left closed when the generator breaker is
closed. If the application does not require an idle speed setting, the Rated Speed
input can be left closed at all times. This can be done by connecting it directly to
the positive Discrete Input Power source.
