COMMISSION TESTS
Autoreclose test No Operation
No operation / 3 pole test /
Pole A Test / Pole B test /
pole C test
Where the relay provides an auto-reclose function, this cell will be available for testing the
sequence of circuit breaker trip and auto-reclose cycles with the settings applied.
Issuing the command ‘Trip 3 Pole’ will cause the relay to perform the first three phase
trip/reclose cycle so that associated output contacts can be checked for operation at the
correct times during the cycle. Once the trip output has operated the command text will
revert to ‘No Operation’ whilst the rest of the auto-reclose cycle is performed. To test
subsequent three phase auto-reclose cycles repeat the ‘3 Pole Trip’ command.
Similarly, where single pole auto-reclosing is available, the cycles for each single pole can
be checked by sequentially issuing the ‘Trip Pole A’, ‘Trip Pole B’ or ‘Trip Pole C’, as
appropriate.
Note: The factory settings for the relay’s programmable scheme logic has the ‘AR
Trip Test’ signal mapped to relay 3. If the programmable scheme logic has
been changed, it is essential that this signal remains.
Red LED Status 000000000000000000
This cell is an eighteen bit binary string that indicates which of the user-programmable
LEDs on the relay are illuminated with the Red LED input active when accessing the relay
from a remote location, a ‘1’ indicating a particular LED is lit and a ‘0’ not lit.
Green LED Status 000000000000000000
This cell is an eighteen bit binary string that indicates which of the user-programmable
LEDs on the relay are illuminated with the Green LED input active when accessing the
relay from a remote location, a ‘1’ indicating a particular LED is lit and a ‘0’ not lit.

24/27V, 30/34V, 48/54V, 110/125V,
220/250V, Custom
Sets the nominal battery voltage for all opto inputs by selecting one of the five standard
ratings in the Global Nominal V settings. If Custom is selected then each opto input can
individually be set to a nominal voltage value.

24/27V, 30/34V, 48/54V, 110/125V,
220/250V
Each opto input can individually be set to a nominal voltage value if custom is selected for
the global setting.
Opto Filter Ctrl 0×FFFFFFFF
This menu is used to control the relay’s opto-isolated inputs L1 (last digit) to L32 (first digit).
Hexadecimal values, from 0 (hexa) = 0000 (binary) to F= “1111”, are used to control four
opto-isolated inputs. . A binary ‘1’ indicates an energized and operating relay, a binary ‘0’
indicates a de-energized.
