Method and elevator
A method for controlling movement of an elevator car includes driving the car vertically to a landing; activating a park brake; and holding the car immovable with the park brake. The holding includes compressing a guide rail by compression members with a first compression force; opening a door for allowing loading and/or unloading the car; maintaining the door open for allowing loading and/or unloading the car while the car is held immovable; and starting closing movement of the door. After the starting closing movement of the door, relieving the brake for allowing the elevator car to start to move vertically. The relieving includes reducing the compression force of the brake, to be smaller than the first compression force, such that the compression members start sliding vertically against the guide rail; maintaining compression with a smaller compression force than the first compression force, allowing the compression members to continue to slide vertically against the guide rail; and thereafter removing the compression.

Elevator safety system
An elevator safety system (20) for an elevator system (2) with a self-diagnostic functionality includes at least two safety channels (22a, 22b), wherein each safety channel (22a, 22b) is configured for supplying a safety signal (23a, 23b) in case a safety issue has been detected. The elevator safety system (20) comprises a self-diagnostic evaluator (24), which is configured for receiving any safety signals (23a, 23b) supplied via the safety channels (22a, 22b); starting a timer (25) for measuring a predetermined period of time in case a safety signal (23a, 23b) is supplied on one of the safety channels (22a, 22b); and stopping any further operation of the elevator system (2) in case the received signal (23a, 23b) is still supplied after the predetermined period of time has expired.
