ASCII Command Reference
Description of Commands
Undetermined - check wiring). See Disconnect Switch Close and Open
Control Logic on page P.12.2. Use the 89OPENn Relay Word bit as part of a
SEL
OGIC Output control equation to open the appropriate disconnect switch.
If the relay is disabled and you attempt an 89OPEN n command, the relay
responds
Command aborted because the relay is disabled. If the circuit
breaker control enable jumper J18C (BREAKER) is not in place, the relay
aborts the command and responds
Aborted: the breaker jumper is not
installed
.
When the 89OPEN n command is issued and the circuit breaker control
enable jumper is in place, the relay responds
Open DISNAMn (Y/N)? If you
answer Y <Enter>, the relay responds
Are you sure (Y/N)? If you answer Y
<Enter>, the command is executed. If the response to either prompt is not y or
Y, the relay responds with
Command Aborted.
AACCESS
Use the AAC command to gain access to Access Level A (automation). See
Access Levels on page P.10.6 for more information.
ACCESS
Use the ACC command to gain access to Access Level 1 (monitor). See
Access Levels on page P.10.6 for more information.
BACCESS
Use the BAC command to gain access to Access Level B (breaker). See
Access Levels on page P.10.6 for more information.
BNAME
The BNA command produces ASCII names of all relay status bits for Fast
Meter Compressed ASCII. See Section 2: SEL Communications Protocols in
the Communications Manual for more information on Fast Meter and the
Compressed ASCII command set.

NOTE: The number of disconnects
supported depends on the pre-
defined one-line diagram selected by
the Bay Control Setting, MIMIC.
NOTE: If a disconnect switch is not
defined in the one-line diagram
selected, the open and close logic for
the undefined disconnect switch still
operates.
