Ground Fault Test
This function will test the ground fault trip function of the
controller to ensure proper operation. When selected, the
controller
will
generate
an
artificial
ground
fault
current; if
the ground fault current is sensed as being greater than 30
mA, the test passes. The GF test function will verify actual
ground fault current and heater trip. Status of the test will
be
displayed
as
pass
or
fail.
If
this
test
has
been
invoked
by the “Now” option and it
passes, the user is prompted to reset the ground fault
trip, at which time the load is capa- ble of being re-
energized as required. If this test has been invoked by
the “Autotest” option and it passes, the load is allowed
to be reenergized as required. If this test has been
invoked by the Autotest cycle and it fails, an Autotest
alarm is generated but the load is allowed to be
reenergized as required.
