GENERAL INFORMATION
SECTION 1.6
OPERATING INSTRUCTIONS
This DIP switch position is only read at board power
up. If the DIP switch position is changed, power to the
board must be cycled for the micro controller to recog-
nize the new DIP switch position.
Low speed exercise will be handled as follows:
1. The standard start sequence will be initiated.
2. The unit will run at 2,400 RPM.
3. If utility is lost during exercise, the controller will do the
following:
• Wait 10 seconds for utility to return.
• If utility returns within 10 seconds, continue to exer
-
cise at 2,400 RPM.
• If utility is still lost after 10 seconds, run the engine
up to 3600 RPM and transfer the load. At this time
the controller will exit the exercise routine and
assume full automatic operation.
PROTECTION SYSTEMS:
Unlike an automobile engine, the generator may have
to run for long periods of time with no operator pres-
ent to monitor engine conditions. For that reason, the
engine is equipped with the following systems that
protect it against potentially damaging conditions:
• Low Battery
• Low Oil Pressure Sensor
• High Temperature Sensor
• Overcrank
• Overspeed
• No RPM Sense
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 fol
-
lowing 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 installa-
tions 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 con-
tacts are at their UTILITY position, i.e., the load is
connected to the power supply. If necessary, manu-
ally 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 trans-
fer 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” (genera-
tor) 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 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 electri-
cal loads.
