  • a priority code is provided between these two types of command: priority belongs to the order that received the most recent order.
  • Control orders applied to TL and CT terminals correspond to edges, which means that the last validated edge imposes its state on the electromagnet 36.
  • the operation of the remote control unit 16 is carried out as follows:
  • each remote control command issued by the rocker 82 to the static power switch 80 causes the excitation of the electromagnet 36 and a change of state of the main movable contacts 33 of the poles 12, 14.
  • This remote control command can come either from the first impulse command associated with the input terminal TL (closing of the push button 74), or from the second assignable command according to the state of the selector S, and associated at the CT input terminal (closing of contact 76).
  • the first command corresponds to an operation of the device 10 in remote control mode, each pulse applied to the input terminal TL causing a change of state of the main contacts 33.
  • Contact 76 can be activated by a clock, timer or automaton (not shown), so as to apply control slots to the input terminal CT, each slot having a width generally greater than that of the pulses of the first control ( see fig. 5).
  • the order of control at the output of the NAND circuit 120 depends on the state of the contact 76 generating the slot at the input terminal CT, and on the state of the detector 98 representing the position of the movable main contacts 33.
  • the passage in the logic 1 state of the output of the NAND circuit 120 corresponding to an order to change the position of the contacts 33 requires that the contact 76 and the detector 98 are at logic levels different from each other, c that is to say that the main contacts 33 are open when the control contact 76 is closed, or that the contacts 33 are closed when the contact 76 is opened.
  • the closure of the contact 76 generates a rising edge of the slot which causes the closing of the main contacts 33.
  • the opening of the contact 76 generates a falling edge of the slot which controls the opening of the main contacts 33.
  • FIGS. 7 and 8 show, in the active position of the selector S, a detailed phase of a timing diagram in contactor mode showing the signals A to P at different points of the electronic circuit 66 of FIG. 4, respectively during a remote control for closing and opening the main contacts 33.

  • the second branch circuit 118 which applies a pulse F to the input E3 of the NAND gate 110 instead of the permanent logic 1 state of the signal B during an opening remote control (FIG. 8) .
  • the presence of the branch circuits 116, 118 creates an asymmetry between the control signal CT and the signal C of the detector 98, which is used only to validate or invalidate the control signal CT. This asymmetry does not occur during the normal closing or opening remote control phases, but is essential in the event of manual closing or opening operation by the handle 60 generating forced operation of the device 10. This property is illustrated on the right side of figs. 7 and 8. In FIG. 7 is simulated beyond the instant t1, a manual opening by the lever 60 intervening after a remote control for closing the contacts 33.
  • This forced manual opening causes a change of state of the detector 98 resulting the switching of signals C and G.
  • the output signal K of the NAND gate 120 is in logic state 0, which means that the device 10 accepts forced operation.
  • the absence of the first branch circuit 116 would signify a permanent logic state 1 of signal E, which would induce a counter-command (logic state 1 of signal K) resulting in a remote-controlled closing of the contacts 33 by the electromagnet 36.
  • FIG. 8 is simulated beyond the instant t2, manual closing by the lever 60 intervening after a remote control for opening the contacts 33.
  • the withdrawal of the contact pad of the selector S neutralizes the action of the detector 98 of the position of the contacts 33, and prohibits the operation of the second control in contactor mode.
  • the input terminal CT nevertheless remains accessible to form a command input by pulses, decoupled from the first command associated with the input terminal TL.
  • the input terminals CT and TL of the electronic control circuit 66 are practically insensitive to the capacitive currents likely to appear on a very long connection cable connecting the contacts 76, 74 to the corresponding terminals CT, TL.
  • the voltage VN between the supply terminal N and the earth of the electronic circuit 66 is constituted by a periodic signal with positive half-waves, determined by a diode 78 of the rectifier bridge 77.
  • the leakage capacity of the connecting cable is positively charged at a value substantially equal to the average voltage of VN.
  • the voltage at the input of the inverter 102 of the logic circuit 84, and of the inverter 86 of the monostable flip-flop 82 is close to zero.
