20 Voltmaster Engine-Driven Generators
Operation: Operating the generator
3.2 Operating the generator
3.2.1 Ground-fault protection
The generator features total ground-fault protection. When a
ground fault occurs on any receptacle:
■
The ground-fault circuit interrupter (GFCI) fault-sensing module
trips the generator’s main circuit breaker
■
Power to all receptacles is disengaged
■
A red LED on the control panel lights up, indicating a ground fault
If a ground fault occurs:
1. With the engine running, remove all loads.
2. Push the reset button on the GFCI fault-sensing module
3. Switch the main circuit breaker to the on position.
4. If the ground-fault condition continues with no load on the
generator, contact an authorized service center.
5. If the condition continues after putting a load on the generator:
a. Repeat steps 1 through 3.
b. Try a different load using any receptacle.
c. If the ground-fault condition does not reoccur, the problem is
likely with the equipment or cord that was connected when
the fault reoccurred.
d. If the ground-fault condition reoccurs, contact an authorized
service center.
Test the GFCI module at least once a month, and more regularly if
the generator is being used often, by starting the generator and
pushing the test button on the GFCI module. The test is successful if
the reset button pops with an audible “click” and the red LED
indicator lights up. To reset the generator after a successful test,
follow steps 1 through 3, above.
