CLO (Close)
Access Level 2
The CLO command asserts the CC Relay Word bit that can be programmed to
an output contact to close circuit breakers. See Section 4: Control Logic.
To issue the CLO command, enter the following:
=>>CLO <Enter>
Close Breaker (Y/N) ? Y <Enter>
Are you sure (Y/N) ? Y <Enter>
=>>
Responding y/y to both prompts asserts Relay Word Bit CC for one
processing interval. Typing N <Enter> after either of the above prompts will
abort the command.
The CLO command is supervised by main board jumper JMP24. If the jumper
is not in place (jumper JMP24 = OFF), the relay will not recognize the CLO
command and responds “Aborted: No Breaker Jumper.”
CON (Control)
Access Level 2
The CON command is a two-step command you can use to control Relay
Word bits RB1 through RB8, see Section 4: Control Logic. [At the Access
Level 2 prompt, type CON, a space, and the number of the bit you wish to
control (1–8).] The relay responds by repeating your command followed by a
colon. At the colon, type the Control subcommand you wish to perform (See
Tab le 7. 2).
The following shows the steps necessary to pulse Remote Bit 5 (RB5):
=>>CON 5 <Enter>
CONTROL RB5: PRB 5 <Enter>
=>>
You must enter the same remote bit number in both steps in the command. If
the bit numbers do not match, the relay responds “Invalid Command.”
See Remote Control Switches on page 4.9 in Section 4: Control Logic.
