Pulse on (Parameters > Breakers > [Breaker] >
Pulse time ON)
To trip a pulse breaker:
1. Number of trip breaker alarms: The number of active
alarms with a Trip [breaker] (or similar) alarm action.
2. Trip breaker: Breakers > [Breaker] > Control > [*B] trip
(digital output). The controller activates this output until
all alarms with a Trip [breaker] (or similar) alarm action
are not active.
3. Open breaker: Breakers > [Breaker] > Control > [*B]
open (digital output). The controller activates this output
until there is breaker open feedback, or for the Pulse
time ON.
4. Breaker closed feedback: Breakers > [Breaker] >
Feedback > [*B] closed (digital input). This input is
deactivated when the breaker is opened.
5. Breaker open feedback: Breakers > [Breaker] >
Feedback > [*B] open (digital input). This input is
activated when the breaker is opened.
5.3.4 Continuous breaker
CAUTION
Due to class requirements, this breaker type is not suitable for marine use. This is because, if the controller failed, then the
breaker would open and the ship would lose power.
You can configure a continuous breaker to use a open breaker signal, an close breaker signal, or an open and a close breaker
signal to open and close the breaker. Configuring both an open and a close breaker signal for a continuous breaker ensures that
synchronisation is precise and that AC protections meet the required operation times.
