CLEARING AN “ERROR” CODE
An error code occurs on the ASCO control board if
the generator set fails to start or there is some other
malfunction. BOTH

ing to the ASCO 65 owner’s manual.
This completes your installation and unit testing.
ALWAYS leave the system in automatic mode unless

hand toggle switch on the generator control panel
must be left in the “
ON” position.

insure high reliability and a long life for the generator
set and Automatic Transfer Switch.
*****************
***** WARNING *****
*****************
When performing any type of maintenance on this
equipment make sure the selector switch on the
generator set is in the off position. If you are work-
ing on the Automatic Transfer Switch, confirm with a
reliable meter that all power has been disconnected.
AUTOMATIC TRANSFER SWITCH
Clean and inspect the switch once a year. De-ener-
gize all power sources, both line and generator set,
then brush and vacuum away any excessive dust or
dirt accumulation.At this time, with the contactor de-
energized, you can remove the contactor covers and
check the contacts. Make sure contacts are clean
and not burned or pitted.
ENGINE GENERATOR SET
Service the engine in accordance with the engine
manufacturer’s manual provided with your new
equipment. Routinely remove debris and dirt from
around the inside generator enclosure. Insure that
the air intakes are free from leaves and other debris
at all times.
Clean and inspect battery terminals a least twice a
year. Check the battery water level at least twice a
year.
Other than keeping the generator set clean and
free of debris, there is no other routine or preventa-
tive maintenance required as long as the generator
is run biweekly to keep it dry and in good working
order.
COLD WEATHER OPERATION
Extreme cold weather operation requires special
considerations. Higher CCA batteries are required
for cold weather starting; 650 CCA or larger are rec-
ommended. In addition you should consider install-
ing an oil heater kit and a battery warmer for reliable
starting during cold weather.
