position. The switch is now powered by the
standby generator.
8. Turn ON the circuit breaker/electrical loads
p
owered by the generator.
9. Connect a calibrated AC voltmeter and a frequency
me
ter 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
m
inutes. 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
e
lectrical loads.
12. Move the Main Circuit Breaker switch on the
g
enerator control panel up to the OFF (or open)
position.
13. Allow the engine to run at no-load for 2-5 minutes.

. Press 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 a
fter installation to ver-
ify correct operation.
1. Verify auxiliary shutdown switches are ON (I).
2. Press MANUAL key on control panel keypad to
star
t 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
a
uxiliary switch, ver-
ify operation of second auxiliary switc
h.
• If engine does not stop, auxiliary
shutdown
switch is not functioning correctly. Contact an
IASD.
NOTE: Auxiliary
shutdown switches are not intended to
be a primary means to shut down generator under nor-
mal operating conditions. Accidental a
ctivation 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. Verify that the generator is OFF. A red LED on the
control
panel illuminates to confirm that the system
is in the OFF mode.
2. Install front cover of the
transfer switch.
3. Turn ON the utility power s
upply to the transfer
switch, using the means provided (such as a utility
main line circuit breaker).
NOTE: Transfer Switch will transfer
back to utility
position.
4. Move the Main Circuit Breaker switch on the
ge
nerator control panel up to the ON (or closed)
position.
5. Press AUTO on the control panel. The system is
no
w ready for automatic operation.
6. Turn OFF the utility power
supply to the transfer
switch.
With the generator ready for automatic operation, the
engine w
ill 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.
