Description of Commands
CHI
Use the CHI command to gather one-line descriptions of event reports.
CHI TERSE
The CHI TERSE command returns a Compressed ASCII event report
without the event report label lines.
CLOSE n
Use the CLOSE n command to close a circuit breaker. The main board circuit
breaker jumper (on connector J18C) must be in place. Further, you must set
relay setting NUMBK := 2 to issue a CLOSE 2 command.
The CLOSE 1 and CLOSE 2 commands assert Relay Word bits CC1 and
CC2, respectively. Relay Word bit CC1 is a variable in the factory default
manual close SEL equation BK1MCL Circuit Breaker 1. Typically, you
program Relay Word bit CC2 in the manual close SEL
OGIC control equation
BK2MCL for Circuit Breaker 2. The relay uses these equations and additional
relay logic to assert a control output (for example, OUT103 := BK1CL) to
close a circuit breaker. See Control Outputs on page U.2.7, and Section 2:
Auto-Reclosing and Synchronism Check for more information.
If the circuit breaker control enable jumper J18C is in place, the relay
responds,
Close breaker (Y/N)? When you answer Y <Enter> (for yes), the
relay prompts,
Are you sure (Y/N)? If you again answer Y <Enter>, the
relay asserts the Relay Word bit for one processing interval.
