To test the automatic start Transfer Switches follow the instruction
in the operator’s manual you received with your transfer switch. If
you get a fault light during the initial start up or prior to start up it
is most likely a false warning light. Simply reset the ATS and
start over.
Once you have completed testing of the ATS, be sure you
ALWAYS leave the system in standby mode unless servicing the
unit. For standby operation, press the AUTO button on the front of
the engine control. The green light should light up next the AUTO
button.
SETTING THE EXERCISER CIRCUIT
For all ATS see the instruction manual shipped with the ATS for
instruction on setting the exercise circuit in your ATS
