OFF — The generator will not start and run in this position.
MANUAL — The control board will start and run the generator whenever the switch is in the manual posi- tion.
AUTO — The control board will monitor the
DANGER
With switch set to AUTO, engine can crank and
!start suddenly without warning. Such automat- ic start up normally occurs when utility source voltage drops below a
NOTE:
If the generator is installed in conjunction with an engineered GTS type transfer switch, refer to the applicable transfer switch manual for exact oper- ating parameters and timing sequences.
For proper battery charger operation, it will be nec- essary to supply a fused 240VAC utility fed supply to terminals N1 and N2 in the control panel.

3.2.1 AUTO/OFF/MANUAL SWITCH
Use this
•Set the switch to AUTO for fully automatic opera- tion. See “Automatic Operation” (Section 3.5).
•Set switch to MANUAL position to crank and start the generator engine.
•Set switch to OFF position to shut down an oper- ating engine. With OFF selected, operation will not be possible.
This fuse will not remove the + battery input power from the PCB when it opens. This means the exercise timer will not be reset.
3.2.5 SET EXERCISE TIME SWITCH
This switch allows programming the generator to start and exercise automatically. “See Weekly Exercise Cycle.”
