AUTOMATIC START/STOP OPERATION
The pump can be configured to start automatically by adding dry-contact closure float
level switches. Ensure that the dry-contact closure float switch harness is connected to
the port on the back of the control box. Contact the Generac Mobile Products, LLC
Technical Service Department at 1-800-926-9768 for more information.

Port
Turning the key switch to the AUTO START position causes all LEDs to illuminate once the AUTO STANDBY indicator
is illuminated and the startup screen is displayed while a self test is performed. After the startup screen is cleared,
the display shows the transducer reading and switch status on the Transducer/Switch gauge. All other CANbus
values will show since the ECU is not energized at this time. After one minute, the display is powered down
to reduce battery drain. The automatic start/stop system is still functioning as indicated by the Auto Standby LED.
For electronically governed units, once the config-
ured automatic start condition exists, the display
powers up, the panel starts the engine and follows
the throttle control profile configured (refer to
Figure 12). The flexible throttle profile includes var-
ious speeds and times for a variety of scenarios.
When the configured stop conditions exist, the panel
reduces the engine speed per the throttle profile and
stops the engine. If the configured start conditions
exist before the shutdown process is complete, the
engine will return to the previous speed until the stop
condition exists.

WARNING
When the key switch is turned to the AUTO START position and a start condition
exists, the panel will start immediately. Always configure parameters by turning the
key switch to the RUN position. DO NOT configure the panel in the AUTO START
position. Always use lock out/tag out procedures when servicing autostart equipment.
Start and Stop Events
The start and stop events are determined by the combination of Start/Stop mode and function.
Start/Stop Modes:
Sngl Switch Switch one controls automatic operation.
Dual Switch Both switch inputs control automatic operation.
Transducer The transducer input controls automatic operation.
Xducer & Sw The transducer input controls automatic operation with dual switch mode as the backup. The switch
inputs override the transducer if actuated when the transducer is not calling for an automatic cycle.
Start/Stop Functions:
Empty Uses the selected mode to reduce the level or pressure.
