Option details

Contact #1 CLOSE

The open operation is initiated after contact channel #1 is closed. If this
option is selected, the DigiTMR S2 will first initiate a CLOSE command
and then send an OPEN command only when it detects that the main
contact #1 is closed. This mode accurately simulates the closing of a
breaker on a fault condition.

Set DELAY

A delay from 10 to 500 milliseconds can be set between the CLOSE and
OPEN command. When a delay is used in the operation, it may not
represent a true breaker operating condition.

No DELAY

Both the CLOSE and OPEN commands are initiated by the DigiTMR S2
simultaneously.
