3.2.2. Timing a CLOSE-OPEN Operation Using Contact Channel #1
The CLOSE-OPEN operation of a breaker simulates a condition where a breaker is closed on a
fault. There are three options when timing a CLOSE-OPEN operation:
1. Contact #1 CLOSE
The CT-7000 S2 will initiate a CLOSE operation. The open operation is then initiated after
contact channel #1 is closed. This option closes simulates the breaker closing on a fault
condition in the field.
2. Set DELAY
A delay from 10 to 500 ms can be set between the CLOSE command and the OPEN
command. The CT-7000 S2 will initiate the CLOSE operation and start the delay counter.
The OPEN operation will be initiated when the delay time has elapsed.
