Transfer Switch & Engine Generator
Automatic (remote) Operation
This procedure checks the electrical operation of
the automatic transfer switch. If the actual operation
does not follow this procedure, consult the trouble-
shooting section in the transfer switch manual.
. Turn on the preferred source (utility) circuit
breaker. The Utility Acceptable Light should now
come on as well as the Load On Utility Light. If
these lights fail to come on recheck your incoming
power to insure you have 240 volts nominal. If not,
troubleshoot your utility source before continuing.
2. Press and release the Auto button on the
engine control module (ECM). The auto mode icon
will appear on the screen. The unit is now ready to
be operated from the Automatic Transfer Switch.
3. Turn on the alternate source (generator) circuit
breaker.

DESCRIPTION
The digital controller provides sensing, timing, and
control functions for the ATS. This micro-processor-
based controller includes built-in control buttons and
status lights for control of the ATS and the generator.
PUSH BUTTONS
On the front control display are three push buttons
that control the operation of the generator and the
ATS.
**** CAUTION ****
Before using the transfer test button, be sure
that conditions are safe for running the genera-
tor and for load transfer
TRANSFER TEST Use this button to test the
system. This operation starts the generator and
transfers the load. The controller is shipped with a
load transfer set by default. Changing the exercise
without a load will be discussed later. Be sure that
conditions are safe to do this operation.
BYPASS TIME DELAY Use this button to cancel
the active time delay or exercise period (stops the
generator after cooldown).
SET ENGINE EXERCISER Use this button to set
the automatic exerciser.
INDICATOR LIGHTS
On the front control display are five lights that indi-
cate the status of the sources and the ATS.
UTILITY ACCEPTABLE This light indicates that
the utility voltage is acceptable for connection to the
load.
GENERATOR ACCEPTABLE This light indicates
that the generator voltage and frequency is accept-
able for connection to the load.
LOAD ON UTILITY This light indicates that the
generator voltage is acceptable for connection to the
load.
LOAD ON GENERATOR This light indicates that
the generator voltage and frequency is acceptable
for connection to the load.
