Control unit

A method for installing an elevator system, the method comprising steps of:

• using an at least partially installed traveling body as a movable working platform in the elevator system during an installation of the elevator system, wherein the traveling body is supported by a traction means, and the traveling body has an electronic safety brake;
• creating an operating state of the electronic safety brake by using a control unit adapted to control the electronic safety brake, the control unit including a safety sensor, a processing unit and a signal output;
• connecting the signal output to the electronic safety brake;
• generating a control signal by the processing unit at the signal output, wherein the control signal controls activation of the electronic safety brake;
• detecting an unsafe operating state of the working platform by the safety sensor;
• controlling the signal output due to the detection of an unsafe operating state by the processing unit such that the electronic safety brake is activated by the control signal;
• and
• removing the control unit when the installation of the elevator system is complete.
