4.3 Test Button Uses
The test button can be used for three purposes:
1. With the GFPD-600V in normal mode, pressing the
test button conducts a system test that opens the
breaker, shows a red solid LED, and sounds the buzzer.
2. When a ground-fault error has occurred, pressing the
test button resets the GFPD-600V to the normal condi-
tion.
3. When a wiring error / open breaker alarm has
occurred, pressing the test button resets the GFPD-600V
to the normal condition.
4.2 LED Indications and Audible Warnings
A bi-color LED and buzzer indicate operating status, a
