During the power-up sequence of the relay self-testing is performed as indicated by the
messages displayed on the LCD. If an error is detected by the relay during these self-tests
then an error message will be displayed and the power-up sequence will be halted. If the
error occurs when the relay application software is executing then a maintenance record will
be created and the relay will reboot.
Test Check Action
1
Is an error message or code permanently
displayed during power up?
If relay locks up and displays an error
code permanently then proceed to test 2.
If the relay prompts for input by the user
proceed to test 4. If the relay re-boots
automatically then proceed to test 5
2
Record displayed error, then remove and
re-apply relay auxiliary supply.
Record whether the same error code is
displayed when the relay is rebooted. If no
error code is displayed then contact the
local service centre stating the error code
and relay information. If the same code is
displayed proceed to test 3.
