SEL-387E Instruction Manual
OPE n (Open)
Access Levels B, 2
The OPE n command asserts the OCn Relay Word bit. This bit must be included in the TRn trip
logic setting for Breaker n in order for opening to take place. This logic is described in
Section 4: Control Logic.
To open circuit Breaker n by this command, type OPE n <Enter>. The prompt “Open Breaker n
(Y/N) ?” is displayed. Then “Are you sure (Y/N) ?” is displayed. Typing N <Enter> after either
of the above prompts aborts the opening operation with the message “Command Aborted.” If
both questions are answered Y <Enter>, the breaker will be opened, an automatic message
summarizing the trip will be sent, an Event Report will be created, and the TRIP LED on the
front panel will light. This must be turned off by a TAR R command or by the TARGET
RESET pushbutton on the front panel.
If the main board jumper JMP6B is not in place, the relay responds: “Aborted: Breaker Jumper
Not in Place.”
