Phasor Measurement Unit One-Shot - GE t60 Instruction Manual

7 COMMANDS AND TARGETS
The date and time can be entered here via the faceplate keypad, but if the relay is synchronizing to an external time source
such as PTP, IRIGB or SNTP, the manually entered time will be quickly over-written. The time setting is based on the 24-
hour clock. The complete date, as a minimum, must be entered to allow execution of this command. The new time (if
entered) and date will take effect at the moment the ENTER key is clicked.
The timescale of the entered time should be local time, including daylight time where and when applicable.

 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 command turns on all faceplate LEDs and display pixels for a short duration. The
PERFORM LAMPTEST
command causes the relay to scan the backplane for the hardware modules and update the order code to
ORDER CODE
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
message will be shown.
CODE NOT UPDATED
The is used to perform specific T60 service actions. Presently, there is only one service action available.
SERVICE COMMAND
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 T60 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 T60 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.
The
REBOOT RELAY COMMAND
changes 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.
