3.2.1 AUTO/OFF/MANUAL SWITCH
Use this three-position switch as follows:
• 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.
be possible.
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 pre-set level. To prevent
possible injury that might be caused by such
sudden starts, set AUTO/OFF/MANUAL switch
to OFF before working on or around the unit.
Then, place a “DO NOT OPERATE” tag on con-
trol console.
