Inspection control system switches elevator system between normal and inspection modes and includes: operating device and at least one emergency stop switch in elevator shaft for deactivating normal and/or inspection mode, for preventing and/or interrupting movement of car. In inspection mode, car is manually controlled by operating device via electric motor, wherein elevator system is switched to normal mode or inspection mode by switch of operating device. Inspection control system also includes: detection device for detecting open and/or closed shaft door, alarm generator, operating switch for activating and/or blocking electric motor, control unit that monitors switching state and actuation sequence of switch and emergency stop switch and compares both with reference switching state and reference sequence with regard to detected state of shaft door. Alarm generator generates alarm signal and operating switch blocks electric motor if switching state deviates from reference switching state or actuation sequence deviates from reference sequence.
