Operation
Figure 3-35. Throttling Menu
Idle RPM
Selects the RPM that the control system will request for
idle speed. Idle can be set to compensate for parasitic
loads such as hydraulic pumps or compressors. Idle RPM
is the low speed setting of the optional two state or three
state throttle switches.
NOTE: The minimum engine speed is set by the ECU.
Requesting a lower speed causes the engine to run at the
ECU minimum speed. RPM limits are programmed into
the panel to limit the requested speed. Contact Generac
Mobile Products for information on changing the panel
minimum requested RPM and maximum requested RPM.
Intermediate RPM
Selects the RPM that the control system will request for
intermediate speed. The intermediate speed can be used
to prime pump or charge lines during automatic start and
stop operation. Intermediate RPM is the middle setting of
optional three state throttle switches.
NOTE: Setting the Intermediate RPM to the same speed
as Idle RPM and Ramp to Run to zero seconds is
effectively two speed automatic operation.
Run RPM
Selects the RPM that the control system will request for
run speed. The run speed is the normal operating speed
during automatic start and stop operation. Run RPM is the
high speed setting of the optional two state or three state
throttle switches.
Ramp Up/Down
This submenu configures the speed profile for automatic
start and stop operation.
Figure 3-36. Ramp Up/Down Menu
Warm Up s
Selects the number of seconds to operate at idle speed
before beginning the ramp to intermediate speed. The
warm-up time begins when the starter is disengaged.
Ramp Up s
Selects the number of seconds to ramp from idle speed to
intermediate speed after warm-up.
Intermediate s
Selects the number of seconds to operate at intermediate
speed before ramping to run speed.
Ramp to Run s
Selects the number of seconds to ramp from intermediate
speed to run speed after intermediate warm-up.
Ramp Down s
Selects the number of seconds to ramp from current speed
to idle speed. The ramp down time begins when the
automatic start and stop system detects a stop event.
Cool Down m
Selects the number of minutes to operate at idle speed
after ramp down time. At the end of the cool down period,
the engine will be stopped.
Servo
Configures the servo profile for autostart maintain modes.
Figure 3-37. Servo Menu
Gain
Controls the aggressiveness of the maintain servo modes.
Delay 10mS
Controls how quickly the maintain servo mode responds
to changes in level.
Transducer
This submenu configures the transducer type and set
points.
Type
Selects between Level and Pressure CANplus
Configurator.
