PUSH BUTTONS OERATION
a.
Integral Trip Test:
•
Press the [TEST] button and hold for 3.5s to perform an integral test on the relay ranging from the
analog sensing circuitry to output contact(s) of the relay as well as the relay indicators and display.
•
During the testing process, the first 2s is to simulate the pre-fault alarm condition then follow by 1.5s
testing on the trip time delay. End of time delay, relay trip
b.
Leakage Fault Trip Reset: / Manual Test Trip Reset:
•
Press the [RESET] button once or through digital input port.
c.
ZCT Connection Fault Reset:
•
Press the [RESET] button once or through digital input port.
•
Reset is inhabited if the fault is not rectify.
d.
Parameters Viewing:
•
When the relay is operate normal and healthy condition, press the [RESET] button to step through
the various functions.
•
When step through the parameters, press [RESET] button and hold for 1.5 second to jump direct to
the default [FUNC].
