7.1.5 RELAY MAINTENANCE
PATH: COMMANDS  RELAY MAINTENANCE
This menu contains commands for relay maintenance purposes. Commands for the lamp test and order code are activated
by changing a command setting to “Yes” and pressing the ENTER key. The command setting will then automatically revert
to “No”. The service command is activated by entering a numerical code and pressing the ENTER key.
The
PERFORM LAMPTEST command turns on all faceplate LEDs and display pixels for a short duration. The UPDATE
ORDER CODE
command causes the relay to scan the backplane for the hardware modules and update the order code to
match. If an update occurs, the following message is shown.
There is no impact if there have been no changes to the hardware modules. When an update does not occur, the
ORDER
CODE NOT UPDATED
message will be shown.
The SERVICE COMMAND is used to perform specific G60 service actions. Presently, there is only one service action avail-
able. Code “101” is used to clear factory diagnostic information stored in the non-volatile memory. If a code other than “101”
is entered, the command will be ignored and no actions will be taken. Various self-checking diagnostics are performed in
the background while the G60 is running, and diagnostic information is stored on the non-volatile memory from time to time
based on the self-checking result. Although the diagnostic information is cleared before the G60 is shipped from the factory,
the user may want to clear the diagnostic information for themselves under certain circumstances. For example, it may be
desirable to clear diagnostic information after replacement of hardware. Once the diagnostic information is cleared, all self-
checking variables are reset to their initial state and diagnostics will restart from scratch.
