the actual stopping of the engine.

Note: This menu is divided into 3 sections for controlling the source line breakers Q1..3.
P07.n.01 - Alphanumeric description which identifies the line breaker on the display synoptic panel.
P07.n.02 - Interlock time from the opening instant of the breaker n to the closing of another breaker.
P07.n.03 - Timeout between sending of a control from a line breaker and the actual execution of the operation. After
having sent an opening or closing control to the breaker, alarms A03 or A04 are generated if it is not positio-
ned correctly before the timeout. It works when the auxiliary state contacts of the breakers is programmed
and wired.
P07.n.04 - Minimum opening control time, when the breaker control is defined by means of a pulse (P08.01 = Pulse
breaker). For applications with motorised line breakers, this must be set to a sufficient time to allow complete
charging of the springs. This time is considered also when working in continuous control mode.
P07.n.05 - Closing control pulse time.
P07.n.06 – Otherwise, the breaker control is selected as continuous (P08.01 = Continuous breaker), defines the behaviour
of the board when it switches to the OFF operating mode. OFF = The control relays are de-energised. NOC =
The control relays remain in in their original state (No Change).
P07.n.07 - In case of timeout caused by the line breaker n failing to close (open feedback contact) causes the transfer of
the load on an alternative line.
P07.n.08 - Minimum coil deactivation pulse duration for breaker opening pulse.
P07.n.09 - Time elapsed between minimum voltage opening pulse and breaker spring loading control.
P07.n.10 - This defines whether in case of failure to close the ref. 422684422684 must perform a retry consisting of a
cycle of opening/spring recharging cycles followed by a new closing attempt. The failed closing alarm will be
generated if the second attempt also fails. OFF = Closing is not retryed.
AUT = Retry is manual only. AUT+MAN = Retry enabled in both modes. CLOSING = Closing retry is executed
in AUT or MAN only in case of failed closing but not when breaker opens unexpectedly.
P07.n.11, P07.n.12- Conditional enable of breaker. OFF = Breaker is enabled normally. (Any other setting) = The brea-
ker is enabled only if the selected variable is active. When the variable is not active, if the breaker is open, its
closing will be avoided. If the breaker is closed, it will be opened.
