5.3 Breakers
5.3.1 Breaker types
There are 2 breaker type settings.
Pulse
This setting is for breakers that have 2 separate coils for opening and closing the breaker.
The controller uses these outputs:
• To close the circuit breaker, the Close Gen breaker output is activated. The output is active until the Breaker Close Pulse
timer expires. You can configure a digital input as Breaker Close Feedback and a Breaker Feedback timer. If the
controller does not receive feedback before the Breaker feedback timer expires, a Close Failure alarm is shown. If
Breaker Close Feedback is not configured, then an alarm is not shown.
• To open the circuit breaker, the Open Gen breaker output is activated. The output is active until the Breaker Open Pulse
timer expires. You can configure a digital input as Breaker Open Feedback and a Breaker Feedback timer. If the controller
does not receive feedback before the Breaker feedback timer expires, an Open Failure alarm is shown. If Breaker Open
Feedback is not configured, then an alarm is not shown.
Continuous
This setting is for breakers that have a single coil for opening and closing the breaker.
The controller uses these outputs:
• To close the circuit breaker, the Close Gen Output is activated. You can configure a digital input as Breaker Close
Feedback and a Breaker Feedback timer. If the controller does not receive feedback before the Breaker feedback timer
expires, a Close Failure alarm is shown. If Breaker Close Feedback is not configured, then an alarm is not shown.
• To open the circuit breaker, the Open Gen Output is activated. You can configure a digital input as Breaker Open
Feedback and a Breaker Feedback timer. If the controller does not receive feedback before the Breaker feedback timer
expires, an Open Failure alarm is shown. If Breaker Open Feedback is not configured, then an alarm is not shown.
