terminals in ATS panel.
. Defective transfer switch controller.
3. Defective mechanically switching solenoid in
Automatic Transfer Switch.
4. Retransfer delay still timing out.
NO AC OUTPUT FROM GENERATOR
1. Defective diode.
. Defective voltage regulator.
3. Defective rotor.
4. Defective stator.
5. Defective exciter rotor.
6. Defective exciter stator.
7. AC short in the output leads.
8. Defective field circuit breaker.
CHANGING THE FUEL TYPE
**** CAUTION ****
EQUIPMENT DAMAGE - Do not make any fuel adjustments
or governor adjustments until all pressure readings are in
compliance with specification. See fuel pressure charts (tables
1, 2, and 3).
These engine/generator sets are very easy to convert between
LP or NG. As the engine timing is controlled by the ECU on the
engine you only need to tell it what fuel you want to operate on.
A small rocker switch has been provide on the underside of the
engine control cabinet (see ref L on Page 13) for this purpose.
Opening the rocker switch will tell the ECU mounted on the
engine that you are operating on NG Fuel. Closing the rocker
switch will tell the ECU that the fuel being supplied is LP. The
Advance Power Controller has an idicator light for LP. When this
light is lite the engine is set-up for LP, when the LP light is out the
engine is set up for NG. The ECU will then reprogram the engine
to operate on the proper fuel.
