Do not attempt manual transfer switch opera-
tion until all power voltage supplies to the
transfer switch have been positively turned off.
Failure to turn off all power voltage supplies
will result in extremely hazardous and possibly
fatal electrical shock.
4. Manually set the transfer switch to the STANDBY
position, i.e., load terminals connected to the
generator's E1/E2 terminals. The transfer switch
operating lever should be down.
5. Set the generator's Auto/Off/Manual switch to
MANUAL. The engine should crank and start
immediately.
6. Let the engine stabilize and warm up for a few
minutes.
7. Set the generator's main circuit breaker to its ON
(or closed) position. Loads are now powered by
the standby generator.
8. Turn ON electrical loads. Apply an electrical load
equal to the full rated wattage/amperage capacity
of the installed generator.
9. Connect an accurate AC frequency meter across
terminal lugs E1 and E2. Voltage should be
greater than 230 volts; frequency should be
greater than 58 Hertz.
10. 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 overheating, etc.
11. When testing under load is complete, turn OFF
electrical loads.
12. Set the generator's main circuit breakers to their
OFF (or open) positions.
13. Let the engine run at no-load for a few minutes.
14. Set the Auto/Off/Manual switch to OFF. The
engine should shut down.

CHECKING AUTOMATIC
OPERATION
To check the system for proper automatic operation,
proceed as follows:
1. Check that the Auto/Off/Manual switch is set to
OFF .
2. Manually set the transfer switch to the UTILITY
position, i.e., load terminals connected to the util-
ity power source side.
3. Turn ON the utility power supply to the transfer
switch, using the means provided (such as a util-
ity main line circuit breaker).
4. Set the Auto/Off/Manual switch to AUTO. The sys-
tem is now ready for automatic operation.
5. Turn OFF the utility power supply to the transfer
switch.

With the Auto/Off/Manual switch at AUTO, the engine
should crank and start when the utility source power
is turned OFF . After starting, the transfer switch
should connect load circuits to the standby side. Let
the system go through its entire automatic sequence
of operation.
With the generator running and loads powered by
generator AC output, turn ON the utility power sup-
ply to the transfer switch. The following should
occur:
• After about six seconds, the switch should transfer
loads back to the utility power source.
• About one minute after retransfer, the engine
should shut down.

SETTING THE EXERCISE TIMER
Your generator is equipped with an exercise timer
(Figure 1.2). Once it is set, the generator will start
and exercise once every seven days, on the day of the
week and at the time of the day that you complete the
following sequence. For example, if you want the gen-
erator to exercise on sundays at 6:00 PM, you will
need to complete the sequence at that exact time.
1. Verify or place the "Auto/Off/Manual" switch in the
AUTO position.
2. Hold down the "Set Exercise Timer" switch until
the generator starts (approximately 10 seconds)
and then release.

Set Exercise Timer
3. The generator will start and run for approximate-
ly 12 minutes and then shut down automatically.
The exerciser is now set to run at the same time
and day every week.
The exerciser will only work in the AUTO mode
and will not work unless this procedure is per-
formed. The exerciser will need to be reset every
time the 12 volt battery is disconnected and then
reconnected. The exerciser WILL NOT work if dip
switch 2 (Remote Not Auto) is ON.
