Safety system for an elevator, elevator system, and method for operating such a safety system

A method for operating a safety system for an elevator comprising the steps of:

• providing a control unit for operating the elevator in at least two different operating modes;
• connecting an electronic lock with the control unit;
• providing an electronic key being connectable with the electronic lock, wherein when the electronic key is connected with the electronic lock the control unit only operates the elevator in one of the at least two different operating modes of a first subset of the at least two different operating modes, and when the electronic key is not connected with the electronic lock the control unit only operates the elevator in another of the at least two different operating modes of a second subset of the at least two different operating modes, and wherein a maintenance mode is only available in the second subset of the at least two different operating modes;
• and
• performing a first connection step establishing or interrupting the connection between the electronic key and the electronic lock.

An elevator system including an elevator and a safety system, the safety system comprising:

• a control unit for operating the elevator in at least two different operating modes;
• an electronic lock connected with the control unit;
• and
• an electronic key being connectable with the electronic lock, wherein when the electronic key is connected with the electronic lock the control unit only operates the elevator in one of the at least two different operating modes of a first subset of the at least two different operating modes, and when the electronic key is not connected with the electronic lock the control unit only operates the elevator in another of the at least two different operating modes of a second subset of the at least two different operating modes, and wherein a maintenance mode is only available in the second subset of the at least two different operating modes.
