Date Code 20171006 Instruction Manual SEL-400 Series Relays
ASCII Command Reference
Command Description
within 30 seconds, the relay exits the 89OPEN command and reads the status of
the disconnect inputs. The state of Relay Word bits 89AMn and 89BMn deter-
mine which disconnect status message the relay displays (
Disconnect OPEN,
Disconnect CLOSED, or Status Undetermined - check wiring). Use Relay
Word bit 89OPENn 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 with
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 with
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.
