DEVICE FOR THE POSITION DETECTION OF AN ELEVATOR CAR
The invention relates to a device for detecting the position of an elevator car (40) by means of a sensor and evaluation unit (20, 22, 24), accommodated in a sensor housing (10), which can be arranged on the elevator car, is designed for interaction with a strip (14) having a length and/or position coding and which is connected via a cable connection (26) to a switching unit that is accommodated separately from the sensor housing in a switching housing (12). The switching unit has a safety switch (30) and/or an interrupter contact for an emergency function, especially an emergency stop, of the elevator car. Means (34) are associated with the position detecting device for inputting and storing a speed threshold value, the safety switch or interrupter contact being activated when said threshold value is reached or exceeded. According to the invention, the means for inputting and storing comprise mechanical switching means (34) that are accommodated in the switching housing and that can be manually actuated.
