The invention relates to a system which consists in erasing the recording of an erroneous call either by a push button, which is closed at rest, placed on the line of the hold contact of the floor relays, or by a push button, which is open at rest, linked directly to the erasing floor relay. This applies to communal lifts and is according to type model. For locking lifts, the system consists in stopping at the first level encountered in order to be able to correct the call. The system comprises: an erasing relay 1 which closes the contacts 2 and 3, one of the speed contacts 4 and 5 already being closed when the lift is operated, holding then takes place and the lift decelerates once the relay 6 which is excited when one of the end-of-travel contacts or pulser closes with the arrival of the cabin in the deceleration area. The lift will stop normally in the gate area and the user may then correct his call. <IMAGE>
