position. The switch is now powered by the
standby generator.
8. T
urn ON the circuit breaker/electrical loads
powered by the generator.
9. Con
nect a calibrated AC voltmeter and a frequency
meter across terminal lugs E1, E2, and E3 (if three
phase). Voltage should be approximately unit rated
voltage. Check with clamp on amp meter to ensure
unit is not overloaded.
10. L
et 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. Whe
n testing under load is complete, turn OFF
electrical loads.
12. Move
the Main Circuit Breaker switch on the
generator control panel up to the OFF (or open)
position.
13. Allo
w the engine to run at no-load for 2-5 minutes.
14. Pr
ess OFF on the control panel to shut the engine
down. A red LED illuminates to confirm that the
system is in the OFF mode.
Test Auxiliary Shutdown Switch Operation
The generator is equipped with an independent means of
shutting down prime mover (engine) for use in emer-
gency situations. The shutdown mechanism, when acti-
vated, requires a mechanical reset.
See Figure 3-6. Generators 15 kW and larger are
equipped
with two auxiliary shutdown switches. One aux-
iliary shutdown switch (A) is located
on the generator roof
above and to the right of the viewing window. The second
auxiliary shutdown switch (B) is inside the control panel
enclosure.

Figure 3-6. Auxiliary Shutdown Switches
Test auxiliary shutdown switches
after installation to ver-
ify correct operation.
1. V
erify auxiliary shutdown switches are ON (I).
2. Pre
ss MANUAL key on control panel keypad to
start engine.
3. With
engine running, set one auxiliary shutdown
switch to OFF (O). Engine should shut down imme-
diately.
If
engine stops, set auxiliary shutdown switch to
ON (I), clear alarm on controller, and restart engine
to verify generator is operating normally. After veri-
fying normal operation of first
auxiliary switch, ver-
ify operation of second auxiliary s
witch.
If
engine does not stop, auxiliary shutdown
switch is not functioning correctly. Contact an
IASD.
NOTE: Aux
iliary shutdown switches are not intended to
be a primary means to shut down generator under nor-
mal operating conditions. Accide
ntal activation of an aux-
iliary shutdown switch will prevent
generator from
operating during a power outage.
Check Automatic Operation
To check the system for proper automatic operation,
proceed as follows:
1. V
erify that the generator is OFF. A red LED on the
control panel illuminates to confirm that the system
is in the OFF mode.
2. Inst
all front cover of the transfer switch.
3. T
urn ON the utility power supply to the transfer
switch, using the means provided (such as a utility
main line circuit breaker).
NOTE: T
ransfer Switch will transfer back to utility
position.
4. Mo
ve the Main Circuit Breaker switch on the
generator control panel up to the ON (or closed)
position.
5. Pre
ss AUTO on the control panel. The system is
now ready for automatic operation.
6. T
urn OFF the utility power supply to the transfer
switch.
With the generator ready for automatic operation, the
engine
will crank and start when the utility source power
is turned OFF after a 10 second delay (factory default
setting). After starting, the transfer switch connects load
circuits to the standby side. Let the system operate
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 system transfers back to the
utility position and then runs through the cool down cycle
and shuts down.
