5. When certain that input voltage is compatible with battery
charger ratings, turn OFF the power supply to the generator.
6. On the generator panel, set the Auto/Off/ Manual switch to
MANUAL. The engine should crank and start.
7. Let the engine warm up for about five minutes to allow inter-
nal temperatures to stabilize. Then, set the generator’s main
circuit breaker to its ON (or closed) position.
Proceed with caution! Generator power volt-
age is now supplied to the inverter. Contact
with live inverter parts will result in danger-
ous and possibly fatal electrical shock.
8. Connect the AC voltmeter test leads across terminal lugs E1
and neutral. Voltage reading should be 125-120 volts AC.
9. Set the generator’s main circuit breaker to its OFF (or OPEN)
position. Let the engine run at no-load for a few minutes to
stabilize internal engine generator temperatures.
10. Set the generator's AUTO/OFF/MANUAL switch to OFF. The
engine should shut down.
NOTE:
It is important not to proceed until certain that generator AC
voltage and frequency are correct and within the stated limits.

GENERATOR TESTS UNDER
LOAD
To test the generator set with electrical loads applied, proceed as
follows:
1. Set generator’s main circuit breaker to its OFF (or OPEN) posi-
tion.
2. Turn OFF all breakers on the load center of the inverter (if
equipped).
3. Set the generator's AUTO/OFF/MANUAL switch to MANUAL.
The engine should crank and start immediately.
4. Let the engine stabilize and warm up for a few minutes.
5. Set the generator’s main circuit breaker to its ON (or CLOSED)
position. The inverter is now powered by the standby genera-
tor.
6. Turn ON the load center of the inverter system.
7. Connect an accurate AC voltmeter and a frequency meter
across terminal lugs at the inverter.
Voltage should be greater than 120 volts and frequency
•
should be 60 Hz.
8. Let the generator run at full rated load for 20-30 minutes.
Listen for unusual noises, vibration or other indications of
abnormal operation. Check for oil leaks, evidence of overheat-
ing, etc.
9. When testing under load is complete, turn OFF electrical
loads.
10. Set the generator's main circuit breaker to its OFF (or OPEN)
position.
11. Let the engine run at no-load for a few minutes.
12. Set the AUTO/OFF/MANUAL switch to OFF. The engine should
shut down.
2.5
CHECKING AUTOMATIC
OPERATION
To check the system for proper automatic operation, proceed as
follows:
1. Set generator’s main circuit breaker to its OFF (or OPEN) posi-
tion.
2. Check that the AUTO/OFF/MANUAL switch is set to OFF.
5. Turn ON the power supply to the battery charger, using the
means provided (such as a line circuit breaker).
6. Set the generator's main circuit breaker to its ON (or CLOSED)
position.
7. Set the AUTO/OFF/MANUAL switch to AUTO. The system is
now ready for automatic operation.
8. Close or connect Remote 2-wire Start with a test switch
installed at the inverter.
With the AUTO/OFF/MANUAL switch at AUTO, the engine should
crank and start when the remote start contact switch is closed.
Let the system go through its entire automatic sequence of opera-
tion.
With the generator running and loads powered by generator AC
output, and the remote start contacts OPEN. The following should
occur:
About one minute after remote start contacts OPEN (OFF) the
•
engine should shut down.

USING THE AUTO/OFF/MANUAL SWITCH
(FIGURE 3.1)
n
With the switch set to AUTO, the engine may
crank and start at any time without warning.
Such automatic starting occurs when utility
power source voltage droops below a preset
level or during the normal exercise cycle. To
prevent possible injury that might be caused
by such sudden starts, always set the switch
to OFF and remove the fuses before work-
ing on or around the generator or transfer
switch. Then, place a “DO NOT OPERATE”
tag on the generator panel and on the trans-
fer switch.
1. “AUTO” Position – Selecting this switch activates fully auto-
matic system operation.
2. “OFF” Position – This switch position shuts down the engine.
This position also prevents automatic operation.
3. “MANUAL” Position – Set the switch to MANUAL to crank
and start the engine. Transfer to standby power will not occur
unless there is a utility failure.
