CHAPTER 7: COMMANDS AND TARGETS

7.1.4 Relay maintenance

COMMANDS  RELAY MAINTENANCE
 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
reverts to "No." The service command is activated by entering a numerical code and pressing the
— Turns on all faceplate LEDs and display pixels for a short duration.
PERFORM LAMP TEST
— This command causes the relay to scan the backplane for the hardware modules and update the
UPDATE ORDER CODE
order code to match. If an update occurs, the following message displays.
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 displays.
— Restarts the relay so that changes to configuration settings can take effect. In most cases, if changes are
REBOOT RELAY
made to the configuration settings these changes do not take effect unless the relay is rebooted.
With the CyberSentry option, the Administrator and Operator roles can initiate the Reboot Relay command.
— Performs specific B90 service actions. Presently, there are two service actions available. Code
SERVICE COMMAND
"20511" returns all settings to their factory default value. Code "101" is used to clear factory diagnostic information stored
in the non-volatile memory. If a code other than these two is entered, the command is ignored and no action is taken.
Various self-checking diagnostics are performed in the background while the B90 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 B90 is shipped from the factory, the user can want to clear the diagnostic information for
themselves under certain circumstances. For example, you 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 restart
from scratch.
— Saves this data to compact flash memory prior to shutdown. This allows the saved data to be as
SAVE VOLATILE DATA
recent as possible instead of relying on the periodic timer to save the data.
