CONTROL PANEL OPERATION
Turning the key switch to the RUN position energizes the
ECU, all LEDs illuminate once and a startup screen is
displayed while a self test is performed. If the display beeps
for longer than one second, it indicates a self test fault. Users
can attempt to rectify the fault by restoring factory defaults.
Refer to the Configuration menu for details.
Refer to the Troubleshooting section on page 7 for fault
troubleshooting information. Contact Generac Mobile Prod-
ucts, LLC for assistance if the fault persists.
After the startup screen is cleared, the display shows read-
ings on its virtual gauges. Initially the analog gauges are
displayed, but the display uses the last displayed screen on
subsequent startups. Refer to “Preferred Screen Store” for
details.
If the ECU is preheating when the key switch is turned to
the RUN position, the Preheat LED is illuminated. Preheat
time varies with atmospheric and engine conditions. After
waiting for the Preheat LED to extinguish, the engine is
cranked by turning and holding the key switch in the START
position until the engine starts.
Figure 10 - Control Panel
Note: The ECU will not preheat unless conditions warrant. If necessary, starting the engine may be attempted by
turning the key to the START position without waiting for preheat to expire. The key switch is spring loaded to return
automatically to the RUN position when released.The key switch includes an interlock to prevent the key from being
turned to the START position while the engine is running. The key switch must be turned to the OFF position to reset
the starter interlock before the switch can be turned to the START position again.
THROTTLE CONTROL
The type of throttle operators installed, along with the configured values of minimum requested RPM, idle RPM,
intermediate RPM, run RPM and maximum requested RPM, determine throttle operation. The engine speed can be
adjusted above run RPM and below idle RPM, but the requests can not fall below the set minimum requested RPM
or above the set maximum requested RPM. The ECU determines how the engine responds to the throttle requests
and will not allow the engine speed to fall below the ECU minimum or exceed the maximum RPM.
Note: To change the minimum requested RPM and maximum requested RPM settings, contact Generac Mobile
Products, LLC.
RAMP THROTTLE (SPEED CONTROL SWITCH)
The standard ramp throttle uses a momentary rocker switch to adjust the requested engine speed. When first started,
the requested engine speed is Idle RPM. Pressing and releasing the Rabbit icon increases the speed requested
by 25 RPM. Pressing and holding the Rabbit icon causes the speed to accelerate to full speed in a few seconds.
Similarly, pressing the Turtle icon decreases the requested speed.
