OPERATING INSTRUCTIONS

CONTROL PANEL
GENERAL:
See Figure 1. The front face of this panel mounts
(a) an Auto-Off-Manual switch, (b) a 15 amp fuse,
(c) a 7.5 amp fuse, (d) a set exercise switch and
(e) the protection systems.
120 VAC GFCI OUTLET:
The generator is equipped with an external, 15 amp,
120 volt, GFCI convenience outlet that is located in
the right rear of the generator enclosure. When the
generator is running, in the absence of utility power,
this outlet may be used to power items outside the
home such as lights or power tools. This outlet may
also be used when utility power is present by running
the generator in manual mode. This oultlet does not
provide power if the generator is not running. This
outlet is protected by a 7.5 amp circuit breaker
located in the generator control panel. (Figure 1).

AUTO-OFF-MANUAL SWITCH:
Use this switch to (a) select fully automatic operation,
(b) to crank and start the engine manually, and (c) to
shut the unit down or to prevent automatic startup.
1. AUTO position:
a. Select AUTO for fully automatic operation.
b. When AUTO is selected, circuit board will
monitor utility power source voltage.
c. Should utility voltage drop below a preset level
and remain at such a low level for a preset time,
circuit board action will initiate engine cranking
and startup.
d. Following engine startup, circuit board action
will initiate transfer of electrical loads to the
"Standby" source side.
e. On restoration of utility source voltage above a
preset level, circuit board action will initiate
retransfer back to the "Utility Source" side.
f. Following retransfer, circuit board will shut the
engine down and will then continue to monitor
utility source voltage.

2. OFF Position:
a. Set the switch to OFF to stop an operating
engine.
b. To prevent an automatic startup from occurring,
set the switch to OFF.
3. MANUAL Position:
a. Set switch to MANUAL to crank and start unit
manually.
b. Engine will crank cyclically and start (same as
automatic startup, but without transfer). The unit
will transfer if utility voltage is not available.
DANGER: WHEN THE GENERATOR IS
INSTALLED IN CONJUNCTION WITH AN
AUTOMATIC TRANSFER SWITCH, ENGINE
CRANKING AND STARTUP CAN OCCUR AT
ANY TIME WITHOUT WARNING (PROVIDING
THE AUTO-OFF-MANUAL SWITCH IS SET TO
AUTO). TO PREVENT AUTOMATIC STARTUP
AND POSSIBLE INJURY THAT MIGHT BE
CAUSED BY SUCH STARTUP, ALWAYS SET
THE AUTO-OFF-MANUAL SWITCH TO ITS
OFF POSITION BEFORE WORKING ON OR
AROUND THIS EQUIPMENT.
15 AMP FUSE:
This fuse protects the DC control circuit (including the
circuit board) against overload. If the fuse element
has melted open due to an overload, engine cranking
or running will not be possible. Should fuse
replacement become necessary, use only an identical
15 amp replacement fuse.
7.5 AMP FUSE:
This fuse protects the 12 VDC accessory socket
against overload. If the fuse element has melted open
due to an overload, the 12 VDC socket will not
provide power to accessories. Should fuse
replacement become necessary, use only an identical
7.5 amp replacement fuse.
THE SET EXERCISE SWITCH:
The air-cooled, prepackaged automatic standby
generator will start and exercise once every seven (7)
days, on a day and at a time of day selected by the
owner or operator. The set exercise time switch is
provided to select the day and time of day for system
exercise.
See Section 5 ("The 7-Day Exercise Cycle") for
instructions on how to set exercise time.
DANGER: THE GENERATOR WILL CRANK
AND START WHEN THE SET EXERCISE TIME
SWITCH IS SET TO "ON". DO NOT ACTUATE
THE SWITCH TO "ON" UNTIL AFTER YOU
HAVE READ THE INSTRUCTIONS IN PART 5.
