NOTES

Option details

• Contact #1 CLOSE

The open operation is initiated after contact channel #1 is closed. If this

option is selected, the DigiTMR 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

simultaneously.
