Control Panel Startup / Testing
36 Installation Guidelines for 60 Hz Air-Cooled Generators
Interconnect System Self Test Feature
This controller goes through a system self test at startup,
which checks for utility voltage on DC circuits. This test
prevents damage if installer incorrectly connected AC
utility power sense wires into the DC terminal block. The
controller will display a warning message and lock out the
generator if utility voltage is detected at the DC terminal
block, preventing damage to the controller. Power to con-
troller must be removed to clear this warning.
Utility voltage must be turned on and present at the N1
and N2 terminals inside the generator control panel for
this test to be performed and pass.
NOTE: All appropriate panels must be in place during
any operation of generator. This includes operation by a
servicing technician, while conducting troubleshooting
procedures.
Before starting, complete the following:
1. Verify generator is OFF.
2. Set generator MLCB (generator disconnect) to
OFF (OPEN).
3. Turn OFF all breakers to be supplied by generator.
4. Verify auxiliary shutdown switch(es) are CLOSED
(I).
5. Check engine crankcase oil level and, if necessary,
fill to oil dipstick FULL mark with recommended oil.
Do not overfill.
6. Inspect fuel supply. Gaseous fuel lines must have
been correctly purged and leak tested in accor-
dance with applicable fuel-gas codes. All fuel shut-
off valves in the fuel supply lines must be open.
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 by press-
ing OFF mode button and ENTER button, and restart up
to two more times if necessary. If unit fails to start, con-
tact an IASD for assistance.
