and T2. Apply an electrical load equal to the full rated
wattage/amperage capacity of the installed generator.
10.Connect an accurate AC voltmeter and a frequency
meter across terminal lugs E1 and E2. Voltage should
be greater than 230 volts; frequency should be greater
than 58 Hertz.
11.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.
12.When testing under load is complete, turn OFF electrical
loads.
13.Set the generator main circuit breaker to its OFF (or
open) position.
14.Let the engine run at no-load for a few minutes.
15.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. Set generator main circuit breaker to its OFF (or open)
position.
2. Check that the AUTO-OFF-MANUAL switch is set to
OFF.
3. Turn off the utility power supply to the transfer switch,
using means provided (such as a utility main line circuit
breaker).
4. Manually set the transfer switch to the UTILITY position,
i.e., load terminals connected to the utility power source
side.
5. Turn ON the utility power supply to the transfer switch,
using the means provided (such as a utility main line
circuit breaker).
6. Set the AUTO-OFF-MANUAL switch to AUTO. The
system is now ready for automatic operation.
7. 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 supply
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.
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 day you complete the following sequence.
During this exercise period, the unit runs for
approximately 12 minutes and then shuts down.
Transfer of loads to the generator output does not
occur during the exercise cycle.
A switch on the control panel (see Figure 1, Page 1.6-1)
allows you to select the day and time for system
exercise. To select the desired day and time of day, you
must perform the following sequence at that time.
1. Verify that the AUTO-OFF-MANUAL switch is set
to AUTO.
2. Hold down the set timer switch until the generator starts
(approximately 10 seconds) and then release.
3. The generator will start and run for approximately 12
minutes and then shut down on its own. The exerciser
will then be set to run at that time of day every week.
NOTE:
The
exerciser
will
only
work
in
the
AUTO
mode
and
will
not
work
unless
this
procedure
is
performed.
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)
on
the
controller
printed
circuit
board
is
“ON.”
