operation, preregister: operationcontrolinwhichsignals to stop are registered in advance by buttons in the car and at the landings. At the proper point in the car travel, the attendant in the car is notified by a signal, visual, audible, or otherwise, to initiate the stop, after which the landing stop is automatic. operation, signal: operation control by means of single buttons or switches (or both) in the car, and “UP” or “DOWN” direction buttons (or both) at the landings, by which predetermined landing stops may be set up or registered for an elevator or for a group of elevators. The stops set up by the momentary actuation of the car buttons are made automatically in succession as the car reaches those landings, irrespective of its direction of travel or the sequence in which the buttons are actuated. The stops set up by the momentary actuation of the “UP” and “DOWN” buttons at the landing are made automatically by the first available car in the group approaching the landings in the corresponding direc- tion, irrespective of the sequence in which the buttons are actuated. With this type of operation, the car can be started only by means of a starting switch or button in the car.
control room, elevator, dumbwaiter, material lift: an enclosed control space outside the hoistway, intended for full bodily entry, which contains the motor controller. The room could also contain electrical and/or mechani- calequipmentused directlyinconnectionwiththeeleva- tor, dumbwaiter, or material lift but not the electric driving machine or the hydraulic machine [see A17.1, Nonmandatory Appendix Q]. control space, elevator, dumbwaiter, material lift: a space inside or outside the hoistway, intended to be accessed with or without full bodily entry, which con- tains the motor controller. This space could also contain electrical and/or mechanical equipment used directly in connection with the elevator, dumbwaiter, or material lift but not the electric driving machine or the hydraulic machine [see A17.1, Nonmandatory Appendix Q]. NOTE: See 2.7.6.3.2 for an exception regarding the location of a motor controller. control system: the overall system governing the start- ing, stopping direction of motion, acceleration, speed, and retardation of the moving member. See ASME A17.1–2004, Nonmandatory Appendix A.
designated attendant: where elevator operation is con- trolled solely by authorized personnel (attendant ser- vice, independent, hospital service, and other similar operations). designated level: the main floor or other floor level that best serves the needs of emergency personnel for firefightingorrescue purposes identified bythe building code or fire authority. dispatching device, elevator automatic: a device, the principal function of which is to either (a) operate a signal in the car to indicate when the car should leave a designated landing, or (b) actuate its starting mechanism when the car is at a designated landing displacement switch: a device actuated by the displace- ment of the counterweight, at any point in the hoistway, to provide a signal that the counterweight has moved from its normal lane of travel or has left its guide rails. door: the movable portion(s) of an entrance that closes the openings. It consists of one or more solid face panels which are permitted to be equipped with a vision panel. door, horizontally sliding: a door that moves horizontally. center-opening: a horizontally sliding door con- sisting of two panels, so arranged to open away from each other.
