See 9.8.3.
The GCB circuit breaker is closed, unless the conditions described in 9.8.4.
See 9.8.3.
The GCB circuit breaker closure depends whether the TEST is with or without load (see 9.1)
and on the conditions described in 9.8.4.
From version 1.09, if the bit 3 of the parameter P.0249 is set to "1", after HS315 has arranged
the circuit breakers as described above, the operator has the option of manually open/close
them (see 9.8.9).
See 9.8.3.
The GCB circuit breaker is closed, unless the conditions described in 9.8.4.
When using motorized circuit breakers, we suggest using
the “pulse” commands for both
opening and closing. If the use of the “minimum voltage coil” is required, remember that for
ACB, BCB and LCB it works in the opposite way (the controller activates the command to open
the circuit breaker): in this way, if HS315 is not supplied, those circuit breakers are not opened.
When using contactors, we suggest the use of the stable commands; remember that for ACB,
BCB and LCB they work in the opposite way (the controller activates the command to open
the circuit breaker): in this way, if HS315 is not supplied, those circuit breakers are not opened.
The JI connector provides the exchanging contacts free of potential for the digital outputs 07
and 08. Please use these outputs for the stable commands for GCB and BCB (or for the
command for the “minimum voltage coils”): the command for GCB must be connected on the
NO contact, while the command for BCB must be connected to the NC contact. If the
commands for ACB and LCB are also required, you must use the NC contact of external relays
commanded by other digital outputs of the controller.
Using parameter P.0220, it is possible to set a minimum time below which it is not possible to
invert the command of any circuit breaker. For example, if you set P.0220 to
“2.0”, an opening
command will be activated at least after two seconds from the previous closing command, and
vice versa.
The panel lamps are switched on when the relevant breaker is closed and are switch off when
it is open. In details:
