> elevator service.
>
> 2.1.2 Brakes
>
> Provide the manufacturer\'s standard code approved, spring actuated,
> electrically released brake assembly designated to assure smooth
> stopping under varying loads and for holding car at not less than 125%
> of rated load capacity.
>
> 2.1.3 Bedplates and Mounting
>
> Mount the elevator machine, motor, and brake assembly on heavy cast
> iron or steel plate. Mount the bedplate on support beams or on
> foundation with vibration isolators which effectively eliminate the
> transmission of machine vibration to the building structure. The
> machine shall be located directly over the hoistway on structural
> beams furnished in place by the Elevator Contractor.
>
> 2.1.4 Automatic Leveling Device
>
> The elevator shall be provided with a leveling device designed to
> automatically bring the car to the floor landing. This leveling shall,
> within its zone, be entirely independent of the operating device and
> shall automatically correct over-travel and maintain the car
> approximately level with the landing regardless of change in load
> affecting the stretch of the hoist ropes.
>
> 2.1.5 Sheaves and Beams
>
> Deflecting sheaves shall be a heavy allow iron, accu­rately grooved to
> fit ropes, of suitable size according to conditions, and fitted with
> heavy steel shaft. The sheaves shall be supported by structural beams.
>
> 2.2 [Variable Voltage Control]{.underline}
>
> Provide variable voltage control to assure smooth, accurate speed
> regulation and efficient operation. During acceleration and
> deceleration, the voltage applied to the elevator motor shall be
> gradually varied by automatically varying the field strength of the
> generator without interruption of power.
>
> 2.2.1 Motor Generator Set
>
> The elevator shall be provided with a Motor-Generator Set, compact in
> design, of two-bearing ventilated type with the rotating element
> provided with a single contin­uous steel shaft. The motor-generated
> shall be designed
>
> to operate the moderate speed with high efficiency and low power
> consumption, and to withstand temporary over­loads without undue
> heating. The generator shall be wound for direct current and shall be
> of the multi-polar type provided with interpoles. The A.C. motor shall
> be wound to suit the power supply. Overload relays shall be provided
> to protect the driving motor of the motor-gener­ator set against
> overloads or phase failure, and also to protect the elevator motor and
> generator armature against overload. The motor-generator shall be
> mounted on vibra­tion isolators to minimize transmission of noise and
> vibration to the building structure.
>
> 2.2.1.1 Starter
>
> Magnetic switches for starting the motor-gener­ator set shall be
> provided in the machine room. These switches shall have contact
> provided with suitable springs to maintain proper contact pressure,
> and arc chutes or blowouts to quickly extinguish any arc.

> devices mounted on non-hydroscopic asbestos panels or similar
> material. Provide equipment designed to control starting and stopping,
> to prevent damage to the motor from overload or excess­ive current, and
> to automatically cut off the power supply, apply the brake, and bring
> the car to rest in the event of a safety device operation or a power
> failure. Provide relays to prevent elevator operation in case of phase
> reversal or low voltage or other possible failures which might result
> in malfunction of elevators.
>
> 2.3.1 Controls Duplex Selective Collective Automatic Operation
>
> Control of the elevator shall be automatic in operation by means of
> pushbuttons in the car numbered to correspond to floors served, for
> registering car stops, and by \"up-down\" pushbuttons at each
> intermediate landing and \"call\" pushbuttons at terminal landings.
> The momentary pressing of one or more buttons shall dispatch the car
> to the designated landings in the order in which the landings are
> reached by the car, irrespective of the sequence in which the buttons
> are pressed. Each landing shall be cancelled when answered. When the
> car is traveling in the up direction, it shall stop at all floors for
> which car buttons or \"up\" hall buttons have been pressed. It shall
> not stop at floors where \"down\" buttons only have been pressed,
> unless the stop for that floor has been registered by a car button, or
> unless the down call is at the highest floor for which any buttons
> have been
>
> pressed. Likewise, the pressing of an \"up\" button when the car is
> traveling in the down direction shall not intercept the travel unless
> the stop for that floor has been registered by a car button, or unless
> the up call is the lowest for which any button has been pressed.
>
> When the car has responded to its highest or lowest stop, and the
> stops are registered for the opposite direction, its travel shall
> reverse automatically and it shall then clear the calls registered for
> that direction.
>
> Should both up and down calls be registered at an inter­mediate floor,
> only the call corresponding to the direc­tion in which the car is
> traveling shall be cancelled upon the stopping of the car at the
> landing. Should there be no outstanding calls, one car shall rest at
> the first floor with the other car at rest on the third floor.
>
> 2.3.2 All Cars
>
> The operating buttons in the car and at the landings shall be mounted
> in flush plates of finish selected. The car panel shall also contain
> an emergency stop switch to interrupt the power supply and apply the
> brakes indepen­dently of the regular operating device. The opening of
> the stop switch shall not cancel the registered calls and, after this
> switch is again closed, the car shall continue to answer its various
> calls. The car panel shall also contain a key operated car light
> switch and a fan switch. A main and an auxiliary car panel shall be
> furnished in each car.
>
> The buttons in the car and hall stations shall be of the light-up type
> which will be illuminated when the button is pressed indicating that a
> call has been registered for that landing.
>
> 2.3.2.1 Independent Service
>
> A key operated switch shall be provided for each elevator for
> selection Independent Service oper­ation. When this switch is in the
> Independent Service Position, the elevator shall be discon­nected from
> the control system and all hall calls will be transferred to other
> cars. The elevator taken out of service may then be run from its car
> buttons for any special usage.
>

> \"up\" or \"down\" service. At terminal landings, provide
> single-button stations. When a button is pressed, it shall light up to
> show the call is registered and shall remain illuminated until the
> call is answered.
>
> 2.3.3.3 Car Position Indicator
>
> A car position indicator shall be provided in the car. Indicator shall
> be arranged so that as the car travels through the hoistway, its
