The relay restarts and the ENABLED light is turned on to indicate
the option card was installed correctly.
After reconfiguration, the relay updates the part number, except
for the following indicated digits. These digits remain
unchanged, i.e., these digits retain the same character as before
the reconfiguration. Also, a communications card installed in
Slot C is reflected as an empty slot in the part number. A regular
4 DI/4 DO card and a hybrid 4 DI/4 DO card have the same
device ID. When interchanging these two cards, the part
number for the respective slots should be updated manually.
Use the Status command to view the part number.
Use the PARTNO command from the 2AC level to enter the
exact part number of the relay.
Step 19. Update the side-panel drawing with the drawing sticker
provided in the option card kit. If necessary, replace the rear
panel with the one applicable for the option card and attach the
terminal-marking label provided with the card to the rear-panel
cover. Also, contact SEL for an updated product serial number
label with the updated part number.
Step 20. Reconnect all connection plugs and add any additional
wiring/connectors required by the new option card.
