SECTION 1.6
OPERATING INSTRUCTIONS
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 Page 5.1-3 ("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.
PROTECTION SYSTEMS:
Unlike an automobile engine, the generator may have
to run for long periods of time with no operator
present to monitor engine conditions. For that reason,
the engine is equipped with the following systems that
protect it against potentially damaging conditions:
❏ Low Oil Pressure Sensor
❏ High Temperature Sensor
❏ Overcrank
❏ Overspeed
There are LED readouts on the control panel to notify
you that one of these faults has occurred. There is
also a System Set LED that is lit when all of the
following conditions are true:
1. The AUTO-OFF-MANUAL switch is set to the AUTO
position.
2. The NOT IN AUTO dip switch is set to the OFF position
on the control board.
3. No alarms are present.
TO
SELECT
AUTOMATIC
OPERATION
The following procedure applies only to those
installations in which the air-cooled, prepackaged
automatic standby generator is installed in
conjunction with a prepackaged transfer switch.
Prepackaged transfer switches do not have an
intelligence circuit of their own, as do Generac "GTS"
type transfer switches. Instead, automatic operation
on prepackaged transfer switch and generator
combinations is controlled by circuit board action.
To select automatic operation when a prepackaged
transfer switch is installed along with a prepackaged
home standby generator, proceed as follows:
1. Check that the prepackaged transfer switch main
contacts are at their UTILITY position, i.e., the load is
connected to the utility power supply. If necessary,
manually actuate the switch main contacts to their
UTILITY source side. See Part 5 of this manual, as
appropriate, for instructions.
2. Check that utility source voltage is available to transfer
switch terminal lugs N1 and N2 (2-pole, 1-phase
transfer switches).
3. Set the generator AUTO-OFF-MANUAL switch to its
AUTO position.
4. Actuate the generator main line circuit breaker to its "On"
or "Closed" position. With the preceding Steps 1 through
4 completed, a dropout in utility supply voltage below a
preset level will result in automatic generator cranking
and start-up. Following startup, the prepackaged transfer
switch will be actuated to its "Standby" source side, i.e.,
loads powered by the standby generator.
MANUAL
TRANSFER
TO
"STANDBY"
AND
MANUAL
STARTUP
To transfer electrical loads to the "Standby"
(generator) source and start the generator manually,
proceed as follows:
1. On the generator panel, set the AUTO-OFF-MANUAL
switch to OFF.
2. On the generator, set the main line circuit breaker to it's
OFF or "Open" position.
3. Turn OFF the utility power supply to the transfer switch,
using whatever means provided (such as a utility source
line circuit breaker).
4. Manually actuate the transfer switch main contacts to
their “Standby” position, i.e., loads connected to the
“Standby” power source side.
NOTE:

switches,

Part
5.
5. On the generator panel, set the AUTO-OFF-MANUAL
switch to MANUAL. The engine should crank and start.
6. Let the engine warm up and stabilize for a minute or two
at no-load.
