Wiring examples
More information
See Wiring examples for controller functions, Breaker wiring in the Installation instructions for an example of pulse
breaker wiring.
Inputs and outputs
Assign the breaker inputs and outputs under Configure > Input/output. Select the hardware module, then select the input/output to
configure.
Table 5.3
Breaker configuration
Function I/O Type Details
Breakers > [Breaker] > Control > [*B]
close
Digital output Pulse The controller activates the Close output to close the breaker.
Breakers > [Breaker] > Control > [*B]
open
Digital output Pulse The controller activates the Open output to open the breaker.
Breakers > [Breaker] > Control > [*B]
trip
Digital output Continuous
The controller activates the Trip output when an alarm with a
trip breaker action activates.
The output remains active until all alarms with a trip breaker
action are resolved.
Breakers > [Breaker] > Feedback >
[*B] open
Digital input Continuous
Wire this feedback from the breaker, to inform the controller
when the breaker is open.
Breakers > [Breaker] > Feedback >
[*B] closed
Digital input Continuous
Wire this feedback from the breaker, to inform the controller
when the breaker is closed.
Breakers > [Breaker] > Feedback >
[*B] short circuit
Digital input Continuous
Optional: Wire this feedback from the breaker, to inform the
controller if a short circuit occurs.
Parameters
Configure the parameters under Configure > Parameters > Breakers > [Breaker] configuration > Configuration.
Table 5.4
Parameters for a pulse breaker
Parameter Range Default Notes
Breaker type
• Pulse breaker
• Compact breaker
• Continuous breaker
Pulse
breaker
This breaker requires a pulse signal to close, and a different pulse
signal to open.
Pulse time ON 0.0 to 10.0 s 1.0 s
The length of the synchronisation pulse (that is, the maximum
amount of time that the Breakers > [Breaker] > Control > [*B] close
output is activated).
If the controller receives breaker closed feedback within this time,
the controller stops activating the breaker close output.
Open point (de-
loading)
1.0 to 20.0 % of nominal
power
5 %
The breaker is de-loaded when the power flowing through the
breaker is less than this set point. The nominal power is the
nominal power of the source.
Sequence diagram
The following sequence diagrams show the sequences for closing and opening for a pulse breaker.
