CA 2248335

This monitoring equipment (1) for a drive control for lifts consists substantially of two modules, a safety circuit sensor system (2) and a motor-switching and/or brake- switching circuit (3), wherein the monitoring of a safety circuit (4) and the consequential actions resulting therefrom takes place exclusively by means of electronic components whilst avoiding electrically conductive separating locations. By the use of electronic components, electromechanical switching elements, which have electrically conductive separating locations, can be dispensed with. In addition, an appreciable reduction in the noise level is achieved, since switching noises no longer arise. This has an advantageous effect particularly in the case of lift installations without machine room. Furthermore, the manufacturing costs can be significantly reduced and a high security and reliability of the monitoring equipment (1) can be ensured by the use of usual electronic components.
