This allows defects within one subsystem 25 to be recognized by the other subsystem 25. Thus, redundancy within the locking arrangement 1 is provided.
  • the control devices 11 are set up to control magnetic coils 10.
  • Each subsystem 25 has at least one magnet coil 10, so that each magnet coil 10 of a subsystem 25 can be controlled by the control device 11 of the subsystem 25.
  • the magnetic coils 10 are part of a holding device 7 with which an armature 22 can be held in at least two different positions without energy having to be supplied from the outside.
  • the holding device 7 has an electromagnet. The electromagnet holds the armature 22 in a first position until a current pulse on one of the magnet coils 10 switches the electromagnet and thus moves the armature 22 into a second position different from the first position.
  • the electromagnet also holds the armature 22 in the second position until a current pulse on one of the magnet coils 10 switches the electromagnet over and moves the armature 22 into the first position.

The energization of an electromagnet is sufficient to move the armature 22 into the positions.

If a fault in the magnetic coil 10 of the subsystem 25 is detected, for example an interruption in the circuit of the magnetic coil 10, there is no guarantee that an activation of the magnetic coil 10 will release the sliding element 9. Due to the presence of several subsystems 25 within the hold-open arrangement 1, however, there is a further magnetic coil 10, so that the door 2 can be released by activating the further magnetic coil 10.
