  • a first actuation signal is generated on the actuated direction button 22, by means of which the control unit 5 can recognize the direction in which the elevator car 9 is to be shifted, and accordingly can supply the drive motor 13 with power.
  • the maintenance technician can hold the release button 19 and the respective direction button 22 pressed until the elevator car 9 has been moved to just before a desired target position.
  • the maintenance technician can initiate a controlled braking operation of the elevator car 9 using the maintenance control panel 3.
  • the maintenance technician can continue to depress the actuating element 27 of the direction button 22 held in the first actuated state until its second actuated position 71 and thus the second actuated state B2 are reached.
  • This direction button 22 then generates the second actuation signal.
  • the control unit 5 receives this second actuation signal, it begins to continuously reduce the power supply to the drive motor 13 in a controlled manner.
  • the elevator car 9 is braked in a controlled manner in this way.
  • the control unit 5 can additionally activate its safety brake.
  • the maintenance technician can then release the actuation of the release button 19 and the previously actuated direction button 22 again at time t 2 , and for example to one Deactivate the maintenance control panel 3 at time t 3 and, if necessary, end the maintenance process.
