  • coordination between the lock arrangement 10 and the door drives 300, 301 can be achieved.
  • the control device 110 sends the status “counter lock 200 in unlocked status”.
  • the door drive 301 can now open the passive leaf.
  • the control device 110 sends the status “lock 100 in unlocked status”.
  • the door drive 300 can now open the active leaf. If the control device 110 sends the state “lock 100 and counter lock 200 in the unlocked state”, the door drives 300, 301 can open both the active leaf and the passive leaf.
  • the actuator 180 and the counter-lock actuator 280 work together.
  • the actuator 180 is controlled to move the locking element 140
  • the counter-lock actuator 280 is controlled to move the first and second locking rod connections 250, 255.
  • the actuator 180 moves the locking element 140 via the lock mechanism 160
  • the counter-lock actuator 280 moves the first and second bolt rod connections 250, 255 via the counter-lock mechanism 260. Due to the division of labor between the actuator 180 and the counter-lock actuator 280, motors with a low power can be used for the actuator 180 and the counter-lock actuator 280.
  • the actuator 180 moves into the blocking position, whereby the movement of the locking element 140 is released.
  • the counter-lock actuator 280 also moves into the blocking position, whereby the movement of the locking bar connections 250, 255 is released.
  • the control device 110 and the controller 210 can exchange data to coordinate the activation of the actuator 180 and the opposing lock actuator 280. The data are exchanged via the electrical connection 20.
  • the control device 110 acts as a master and the controller 210 acts as a slave.
  • the control device 110 commands the controller 210 to control the counter lock actuator 280 for unlocking or blocking the counter lock 200.
  • the control device 110 can initially receive the opening command for transferring the counter lock 200 into the unlocked state of the counter lock 200 via the bus system 30 or the control line.
  • the control device 110 decides when it forwards the command to the controller 210.
  • the controller 210 reports the corresponding state of the counter lock 200 to the control device 110 after the successful transfer to the unlocked state or the locked state of the counter lock 200.
  • the control device 110 first causes the actuator 180 to move the locking element 140 into the retracted position. At the same time, the trap 150 is unblocked. The control device 110 uses the
  • Monitoring means 123 determines that the locking element 140 is in the retracted position. Only when the locking element 140 is in the retracted position does the control device 110 command the controller 210 to transfer the counter lock 200 into the unlocked state of the counter lock 200. This prevents the counter-lock actuator 280 from having to move the locking element 140 via the locking element actuator 240.
  • the counter lock 200 is first transferred to the blocked state before the lock 100 is transferred to the blocked state. This ensures that the bolt actuator 240 does not hinder or make the transfer of the lock 100 into the locked state more difficult.
  • the control device 110 decides for the lock 100 and the counter lock 200 when the unlocking period ⁇ T has ended.
  • the control device 110 decides for the lock 100 and the counter-lock 200 whether the unlocking period ⁇ T is started again on the basis of a second opening command ⁇ B2.
  • the control device 110 causes the actuators 180, 280 to move into the locked position before the end of the unlocking time period ⁇ T if a danger signal GS is present.
