SEL-387E Instruction Manual
CLO n (Close)
Access Levels B, 2
The CLO n command asserts the CCn Relay Word bit. This bit must be included in the CLn
Close Logic setting for Breaker n, in order for closing to take place. This logic is described in
Section 4: Control Logic.
To close the circuit breaker with this command, type CLO n <Enter>. The prompting message
“Close Breaker n (Y/N) ?” is displayed. Then “Are you sure (Y/N)?” Typing N <Enter> after
either of the above prompts aborts the closing operation with the message “Command Aborted.”
If both questions are answered Y <Enter>, the breaker will be closed, an automatic message
summarizing the close operation will be sent, and an Event Report will be created.
If the main board jumper JMP6B is not in place, the relay responds: “Aborted: Breaker Jumper
Not in Place.”
CON n (Control RBn)
Access Level 2
This command is used to control the Relay Word bit RBn, or Remote Bit n, n having a value of 1
to 16. The relay responds with CONTROL RBn. The user must then respond with one of the
following: SRB n <Enter> (Set Remote Bit n), or CRB n <Enter> (Clear Remote Bit n), or
PRB n <Enter> (Pulse Remote Bit n). The latter asserts RBn for one processing interval, one-
eighth cycle. The Remote Bits permit design of SEL
OGIC
control equations that can be set,
cleared, or momentarily activated via a remote command.
COP m n (Copy Settings)
Access Level 2
The COP m n command copies settings and logic from setting Group m to Group n (m and n can
be any combination of 1 through 6). After entering the settings into one setting group with the
SET command, copy it to the other groups with the COP command. Use the SET command to
modify copied setting groups. The ALARM output contact closes momentarily when you
change settings in an active setting group but not in an inactive setting group.
