Definitions

  • An accumulation mechanism generally comprises an opening spring and a closing spring intended to ensure a sudden closing and / or opening of the contacts of the device.
  • a single spring can serve as an opening and closing spring, with different reset positions for opening and closing.

  • the voltage U5 is applied to the supply input 24a via suitable contacts for actuating the arming motor.
  • voltage U5 can be applied to input 24a via an opening limit switch contact, which is closes when the device is closed, connected in series with a spring arming limit switch contact, closed when the spring is not armed. This results in automatic start of the spring after closing the contacts of the device and its stop when the spring has reached its reset position.
  • the motor supply circuit 29 can also be used to replace the motor with a standard motor.
  • a standard control device 5 can be used regardless of the type of control desired.
  • the main advantages of the circuit namely the use of standard 3 and 4 relays, independent of the available voltages, and the priority of an opening order over a closing order, are found in all cases, even if the tripping coils Yo and Yf of FIG. 20 remain adapted to the input voltages.
  • the use of a standard motor can be made possible thanks to a suitable motor supply circuit, comprising a chopper-series controlled by a control circuit with pulse width modulation.
