Parameters Setting
•
Step 1: Press [RESET] button to step to desired [FUNC] or parameter.
•
Step 2: Press [
] and [
] buttons simultaneously and hold for 1.5s to enter programming mode.
The [FUNC] digit blink to indicate the relay has enter into the programming mode.
•
Step 3: Press [
] or [
] button to increase or decrease the parameter value.
•
Step 4: To save the selected value, press [
] and [
] buttons simultaneously and hold for 1.5s. It
will exit the programming mode with [DATA] displaying the new setting.
To exit programming mode without saving the selected setting, press the [[RESET] button once.

DIGITAL INPUT PORT *
a.
This digital port is for remotely reset the relay when tripped or ZCT connection fault.
b.
To reset the relay, make a connection between terminals 4 and 5 of the relay.
5.
OUTPUT CONTACTS
Trip Contact
Activated and latch by leakage fault trip, manual test trip or ZCT connection fault
Positive Safety
Contact *
Activated when the relay is power up and function correctly with no tripping.
Pre-fault Alarm
Contact *
Activated when the measured leakage current > 50% of the I
∆
n and self reset when the
measured leakage current < 45% of the I
∆
n.
Activated and latch when the relay is tripped.
Table 3: Output contact description
6.
RECORDS
a.
Record the 3 latest tripped faults current or “tSt” for manual trip test.
b.
The records are stored in non-volatile memory.
c.
To clear the entire record database:
•
Step 1: When the relay is healthy, press [RESET] button to step to most recent trip fault record or
[FUNC] digit shown “A”.
•
Step 2: Press [
] and [
] buttons simultaneously and hold for 3.5s or the [DATA] show “0”. It will
clear the entire fault records database.
