GE Multilin L30 Line Current Differential System 7-37 COMMANDS AND TARGETS 7.1 COMMANDS77.1.5 RELAY MAINTENANCEPATH: COMMANDS RELAY MAINTENANCEThis menu contains commands for relay maintenance purposes. Commands for the lamp test and order code are activatedby changing a command setting to “Yes” and pressing the ENTER key. The command setting will then automatically revertto “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 UPDATEORDER CODE command causes the relay to scan the backplane for the hardware modules and update the order code tomatch. 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 ORDERCODE NOT UPDATED message will be shown.The REBOOT RELAY COMMAND reboots the relay so that changes to configuration settings can take effect. In most cases, ifchanges are made to the configuration settings these changes do not take effect unless the relay is rebooted.With the CyberSentry option, the Administrator or Operator role can initiate the Reboot Relay command.The SERVICE COMMAND is used to perform specific L30 service actions. Presently, there is only one service action available.Code “101” is used to clear factory diagnostic information stored in the non-volatile memory. If a code other than “101” isentered, the command will be ignored and no actions will be taken. Various self-checking diagnostics are performed in thebackground while the L30 is running, and diagnostic information is stored on the non-volatile memory from time to timebased on the self-checking result. Although the diagnostic information is cleared before the L30 is shipped from the factory,the user may want to clear the diagnostic information for themselves under certain circumstances. For example, it may bedesirable 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.SAVE VOLATILE DATA saves this data to compact flash memory prior to shutdown. This allows the saved data to be as recentas possible instead of relying on the periodic timer to save the data.
