FORM 1 - TEST RECORD
GROUND FAULT TEST – D64RPBH13
G/F TEST INTERNAL
Double-clicking the built-in RESET – TEST pushbutton invokes a test which switches an AC voltage
onto the processor’s CT sensor input. The voltage is scaled to simulate a Ground fault current of 1.5
times the G/F trip level set point. The output circuit breaker will trip on G/F after the set delay (plus 0.4 s)
and the AC test voltage will be switched off. The red LED will turn on solid. This proves that the internal
electronics and output circuit breaker are functioning. Optionally, pressing the reset button again will
reset the red LED enabling the green RUN LED. Reclose the circuit breaker (Normal position). No
external power supply is required.
Provision is made for external testing if required. Refer to Figure 1. Select a momentary contact single
pole normally closed pushbutton rated at least 3 Amps at 10 Volts ac. Connect as shown in Figure 1.
When pressed the circuit to the external CT is opened. This results in a trip and the red LED will flash
four 0.25 s flashes (CT Open Circuit). This proves that the current transformer is connected and the
windings are okay, the CT monitor's detection circuit is operating, and the internal electronics and output
circuit breaker are functioning.
RESET
The built-in RESET – TEST pushbutton is used to optionally reset the red LAST TRIP LED in the
D64RPBH13.
The external pushbutton cannot be used to reset the red LAST TRIP LED.
This form provides spaces to record the date the test was performed and the results. Those in charge of the
building’s electrical installation should retain the form in order to be available to the authority having jurisdiction.
