Operational Checks
NOTE: The following procedures require special tools
and skills. Contact an IASD to perform these tasks.
Self Test
Upon startup, controller goes through a system self test
which checks for utility voltage on the 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 generator MLCB (generator disconnect) is
OFF (OPEN).
3. Turn off all circuit breakers/electrical loads to be
powered by the generator.
4. Verify both auxiliary shutdown switches are ON (I).
5. Check coolant and engine lubricating oil levels.
See Inspecting Coolant Level and Hoses and
Checking Lubricating Oil Level and Drain Hose.
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.
Checking Manual Transfer Switch
Operation
See Manual Transfer Operation section of owner’s man-
ual for procedures.
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 generator MLCB (generator disconnect) is
OFF (OPEN).
3. Turn off all circuit breakers/electrical loads to be
supplied 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 verify utility power
source voltage across transfer switch terminals N1,
N2, and N3 (if three-phase). Normal line-to-line
voltage should be equivalent to rated unit voltage.
6. Verify utility power source voltage across terminals
N1, N2, and N3 (if three-phase) and the transfer
switch neutral lug.
7. Turn off utility power supply to transfer switch when
utility supply voltage is compatible with transfer
switch and load circuit ratings.
8. Press MANUAL on control panel to crank and start
engine.
9. Allow engine to warm up for approximately five
minutes. Set generator MLCB (generator discon-
nect) to ON (CLOSED).
10. Connect an accurate AC frequency meter across
transfer switch terminal lugs E1, E2, and E3 (if
three-phase) and verify correct rated frequency (50
Hz or 60 Hz).
11. Use an accurate AC voltmeter to verify generator
output voltage across transfer switch terminals E1
to E2, (E2 to E3 and E3 to E1 if three-phase). Nor-
mal line-to-line voltage should be equivalent to site
specific utility voltage.
12. Successively connect the AC voltmeter test leads
across terminal lugs E1 and Neutral, then E2 and
Neutral (and E3 and Neutral if three-phase). Line-
to-neutral reading in each case should match utility
voltage reading. Verify generator phase rotation
matches utility phase rotation if system is three-
phase.
13. Set generator MLCB (generator disconnect) to
OFF (OPEN).
14. Press OFF on control panel to shut engine down.

DANGER
Electrocution. High voltage is present at
transfer switch and terminals. Contact with live
terminals will result in death or serious injury.
