Interconnect System Self-Test

Upon power up, the controller will go through a system self-test which will check for utility voltage
on the DC circuits. (Nexus & Evolution only)

This is done to prevent damage if you have mistakenly connected AC utility power sense wires into
the DC terminal block.

If utility voltage is detected, the controller will display a warning message and lock out the
generator to prevent damage to the controller.

Power to the controller must be removed to clear this warning.

Utility power must be turned on and present at the N1 and N2 terminals inside the generator control
panel for this test to be performed and passed.
1. Ensure that the generator is OFF.
2. Set the generator's main circuit breaker to the OFF (or OPEN) Position.
3. Turn off all breakers that will be powered by the generator.
4. Check the engine crankcase oil level and if necessary fill to the dipstick Full mark. The generator
comes from the factory with SAE 30 Organic oil.
5. Check the fuel supply. Gaseous fuel lines must have been properly purged and leak tested. All fuel
shutoff valves must be fully open.
 Note: The generator is to be run with all appropriate panels in place, including during trouble
shooting by a technician.
During Initial Startup Only:
 The generator may exceed the normal number of start attempts and experience an Overcrank fault.
 This is due to accumulated air in the fuel system during installation.
 Reset the control board, and restart, up to two more times if necessary.
 If the generator fails to start, contact a service dealer for assistance.
