2. RELAY COMMISSIONING TOOLS
To help minimize the time required to test MiCOM relays the relay provides several test
facilities under the ‘COMMISSION TESTS’ menu heading. There are menu cells which allow
the status of the opto-isolated inputs, output relay contacts, internal digital data bus (DDB)
signals and user-programmable LEDs to be monitored. Additionally there are cells to test
the operation of the output contacts, user-programmable LEDs and, where available, the
auto-reclose cycles.
The following table shows the relay menu of commissioning tests, including the available
setting ranges and factory defaults:

2.1 Opto I/P status
This menu cell displays the status of the relay’s opto-isolated inputs as a binary string, a ‘1’
indicating an energized opto-isolated input and a ‘0’ a de-energized one. If the cursor is
moved along the binary numbers the corresponding label text will be displayed for each logic
input.
It can be used during commissioning or routine testing to monitor the status of the
opto-isolated inputs whilst they are sequentially energized with a suitable dc voltage.
