Operational Checks
NOTE: The following procedures require special tools
and skills. Contact an IASD or an authorized service pro-
vider to perform these tasks.
Self Test
Upon startup, controller goes through a system self test
which checks for utility voltage on DC circuits. This is
done to prevent damage if installer mistakenly connects
AC utility power sense wires into DC terminal block. If
utility voltage is detected, controller displays a warning
message and locks out the generator, preventing dam-
age to the controller. Remove power to controller to clear
this warning.
Utility voltage must be turned on and present at N1 and
N2 terminals inside generator control panel for this test to
be performed and pass.
Complete the following before starting:
1. Verify generator is OFF. A red LED on control
panel illuminates to verify system is off.
2. Verify MLCB on generator control panel is OFF
(OPEN).
3. Turn off all circuit breakers/electrical loads to be
powered by generator.
4. Verify both auxiliary shutdown switches are ON (I).
5. Check fuel level, coolant level, and engine lubricat-
ing oil level. See Check Fuel Level and Fill,
Check Coolant Level and Hoses, and Check
Lubricating Oil Level, respectively.
During initial startup only, generator may exceed normal
number of start attempts and experience an “over crank”
fault. This is due to accumulated air in the fuel system
during installation. Reset control board and restart up to
two more times, if necessary. If unit fails to start, contact
an IASD for assistance.
Check Manual Transfer Switch Operation
See manufacturer’s instructions.
Electrical Checks
Proceed as follows to complete electrical checks:
1. Verify generator is in OFF mode. A red LED on
control panel illuminates to verify system is off.
2. Verify MLCB switch on generator control panel is
OFF (OPEN).
3. Turn off all circuit breakers/electrical loads to be
powered by generator.
4. Turn on utility power supply to transfer switch using
the means provided (such as a utility MLCB).
5. Use an accurate AC voltmeter to check utility
power source voltage across transfer switch termi-
nals N1, N2, and N3 (if three-phase). Normal line-
to-line voltage should be equivalent to rated unit
voltage.
6. Check utility power source voltage across termi-
nals N1, N2, and N3 (if three-phase) and transfer
switch neutral lug.
Use UP ARROW or DOWN ARROW
to select either YES or NO.
Press ENTER.
Select YES to perform exercise at low speed.
Select NO to perform exercise at normal
operating speed.
• Set Exercise Time.
• Use UP ARROW or DOWN
ARROW to increment or decre-
ment hour. Press ENTER.
• Use UP ARROW or DOWN
ARROW to increment or decre-
ment minute. Press ENTER.
• Use UP ARROW or DOWN
ARROW to scroll to day of week.
Press ENTER.
In AUTO, engine starts and runs once each week
at the time and day specified. During exercise
cycle, unit runs approximately 12 minutes and
then shuts down. Transfer of loads to generator
does not occur unless utility power fails.

DANGER
Electrocution. Do not manually transfer under load.
Disconnect transfer switch from all power sources
prior to manual transfer. Failure to do so will result
in death or serious injury, and equipment damage.
(000129)
DANGER
Electrocution. High voltage is present at
transfer switch and terminals. Contact with live
terminals will result in death or serious injury.
