operating panel corresponding to the landings served and a single riser of landing


hall buttons, electrically connected to controller, govern floor selection and direction of travel.

B. Operation: 1. When car is idle and one or more car or landing buttons above the

landing at which car is standing is pressed, the car starts in the Up direction. The car stops on the Up trip at each landing for which a car button or Up landing button is pressed sufficiently in advance of the car arrival at such landings to permit these stops to be made. After each stop, the car proceeds in the Up direction until it reaches the highest landing for which a car or landing call is registered. Stops are made in the order in which the landings are reached, irrespective of sequence in which buttons have been pressed. The car will not stop on the Up trip at any landing in response to a Down landing call unless this call is the highest call registered.

a. Similarly, if car is idle and one or more landing buttons below the landing at which the car is standing are pressed, the car starts in the Down direction, proceeding to the lowest landing for which a button is pressed and stops at each intermediate landing for which car button or Down landing button is pressed.

2. When the car is idle and a button above the car and a button below the car is pressed, the car starts toward the landing corresponding to the button first pressed. The call registered for the landing in the opposite direction from the car will be answered after the car has responded to the farthest call in the direction established by the first button pressed.

3. The minimum time from audible and signal notification that the elevator car is answering a landing call until the doors start to close is 6 seconds (doors fully open for a minimum of 3 seconds), to enable passengers to enter or leave the car. Pressing a car button for another landing before this time elapses, causes the car to start, provided the car door and hoistway doors are closed and interlock circuits established. When the car has answered the farthest call, this interval will permit a car button call to be registered to establish the direction of car travel, even if other landing calls are registered.

4. When all calls have been answered, car remains at landing last served. 2.05 ADDITIONAL CONTROL FEATURES FOR EACH ELEVATOR A. Top of Car Operating Device: 1. Function: Used for inspection and maintenance procedures. 2. Design: Up and Down direction buttons and emergency stop button in

C. Automatic Leveling: 1. Function: Causes elevator to make accurate stops at each landing and

makes adjustments to keep elevator within specified tolerances at the landing.

2. Operation: a. Adjusts elevator if car is more than 1/4 inch above or below

landing level when the car has come to rest at any landing, irrespective of load in car within specified capacity and irrespective of direction of travel.

b. If car is displaced from the floor for any reason other than operation of control buttons, the car returns automatically to a position, level with the landing within 1/4 inch above or below.

D. Independent Service: 1. Function: Causes car to operate only from its car button, and becomes

independent of the hall buttons. 2. Operation: a. When key operated switch is in On position car is removed from

normal style of operation. b. All previously registered car calls are cancelled. c. Car door and hoistway door remain open when car is at a floor,

until a car button for another landing is momentarily pressed. d. If several calls are registered after each stop, a car button must

be pressed to effect door closing. e. Previously registered hall calls shall not be cancelled, but

answered when car is back in normal automatically operation. PART 3 EXECUTION 3.01 INSTALLATION
