DOF.2004 -
“ACB steady opening command”.
DOF.2034 -
“GCB steady closing command”.
DOF.2044 -
“BCB steady opening command”.
DOF.2054 -
“LCB steady opening command”.
For the GCB: the controller disables this output when it must open the breaker.
For the other circuit breakers: the controller enables this output when it must open the
breaker.
HS315 ensures that the DOF.2001 feature «if available» has been active for at least
0.5 seconds.
The digital inputs of the controller can be used for various purposes, when managing circuit
breakers.
The following functions are used by the controller for acquiring the feedbacks of the circuit
breakers:
•
DIF.3001 -
“Status of GCB circuit breaker”.
•
DIF.3002 -
“Status of ACB circuit breaker”.
•
DIF.3006 -
“Status of BCB circuit breaker”.
•
DIF.3007 -
“Status of LCB circuit breaker”.
The controller uses these inputs for:
•
Issuing failed opening or failed closing warnings.
•
For its own operating sequence.
•
It is also used to detect the status of the circuit breaker when it is commanded by
external devices.
•
To show the status of the circuit breakers on the front panel LEDs.
The delay associated to the input is used as maximum time for opening or closing the breaker.
In theory, the controller could operate even without this feedback. In this case, the controller
considers that the breaker is closed once the closing command is issued; it considers that the
breaker is open once the opening command is issued. It is always better to connect the
feedback.
The circuit breakers, normally, include an over current protection. The circuit breaker signals
the activation of this protection by means a contact: it can be acquired by HS315 by its digital
inputs. The following functions are provided:
•
DIF.3011 -
“Trip of GCB circuit breaker”.
•
DIF.3012 -
“Trip of ACB circuit breaker”.
•
DIF.3016 -
“Trip of BCB circuit breaker”.
•
DIF.3017 -
“Trip of LCB circuit breaker”.
