description The invention comprises a control unit for a lift system, wherein the at least one isolation element (12, 31, 32, 33, 34, 35) is designed according to the invention such that the safety circuit (3) can be interrupted for less than 5 msec, preferably less than 2.5 msec, more preferably less than 3 msec, in order to capture the proper operating state of the lift system, in particular a maintenance bridge (5) with which contact is made in the safety circuit (3) and/or a short circuit caused by a fault, in the active state of the safety element (7), in particular of the main contactor (8) or of a functional unit of the drive unit (2), by means of at least one test action.
