SECTION 1.6
OPERATING INSTRUCTIONS
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. 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 star t-up. Following star tup, 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: For instructions on manual operation of
prepackaged transfer switches, see 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.
7. Set the generator main line circuit breaker to its "On" or
"Closed" position. The generator now powers the
electrical loads.
MANUAL SHUTDOWN AND RETRANSFER
BACK TO "UTILITY"
To shut the generator down and retransfer electrical
loads back to the UTILITY position, proceed as
follows:
1. Set the generator main line circuit breaker to its OFF or
"Open" position.
2. Let the generator run at no-load for a few minutes, to
cool.
3. Set the generator Auto-Off-Manual switch to OFF. Wait
for the engine to come to a complete stop.
4. Turn off the utility power supply to the transfer switch
using whatever means provided (such as a utility source
main line circuit breaker)
5. Manually actuate the prepackaged transfer switch to its
UTILITY source side, i.e., load connected to the utility
source.
6. Turn on the utility power supply to the transfer switch,
using whatever means provided.
7. Set the generator Auto-Off-Manual switch to AUTO.
