Car Operating Features
1. Full Collective Operation:
The car shall answer calls in the order in which floors are reached, without respect to the time sequence in which the calls were registered.
Only car calls and up hall calls shall be answered when the car is traveling in the up direction, and only car calls and down hall calls hall be answered when the car is traveling in the down direction, except in the case of the highest or lowest calls which are answered as soon as they are reached, regardless of the direction of travel of the car.
When the car reaches the last registered call for the established direction, it shall reverse and proceed to answer calls in the opposite direction if they are present.
If an excessive number of car calls (quantity to be adjustable) are registered and the passenger load as determined by the weight sensors is less than a predetermined weight, all car calls shall be canceled requiring re-registration of calls.
3. Call Parking Recognition:
Car doors shall only open in response to car and hall demand. Cars being parked without call demand will be parked without door operation.
4. Direction Preference:
At the final stop (highest or lowest call), direction preference shall be given to the hall passenger whereby, if a passenger registers a car call for the original direction of travel before the doors close, it shall not be possible for a waiting passenger at another floor to call the car in the reverse direction.
5. Direction Reversal:
A car without registered car calls arriving at a floor where both up and down hall calls are registered and the hall call is the last one in that direction, shall first respond to the hall call in the direction that the car was traveling; and if no car call is registered for further travel in that direction, the car shall close its doors and immediately re-open them in response to the hall call in the opposite direction. The hall lantern shall always show the direction the car will travel when it leaves a floor.
6. Fan and Light Protection:
The cab's fan and light shall automatically turn off if the car is idle for a selectable period of time.
7. Hall Button Protection:
If the hall button signal system fails, all of the cars in the group
shall enter Hall Button Protection operation. Each car shall answer
all pending car calls. When each car has no further demand, each car
shall travel to the lobby and shut down with the doors open.
8. Landing Passing Tone:
An audible signal located in car operating panel shall sound when the
car passes or stops at a landing.
9. Load Weighing Bypass:
When a car is loaded to a predetermined percent of capacity, the weight sensing devices shall operate causing that car to bypass further hall calls. Operation of the weight sensing devices shall not affect the stopping of the car in response to car calls.
10. Platform Load Weighing:
A device shall measure car load so that proper starting torque is applied to motor.
11. [Special] Rear Openings:
The elevator(s) shall be arranged to serve rear openings at designated floors.
Each car shall be equipped with a power door operator for the rear openings, and the doors shall be arranged to open only at that entrance for which a car or hall call has been registered.
The front car operating panel shall include illuminated floor buttons for both front and rear openings served, and if one or more floors has both front and rear openings at the same level, it shall also contain door open and close buttons for the rear openings. A rear car operating panel shall also be provided.
[Special]. Select for Cars with at least one set of Front and Rear Openings at the same level ]Full Selective Operation shall allow the passenger, through car call button operation to determine whether both front and rear doors will open simultaneously when the car arrives at that landing, or whether front doors only or rear doors only will open. Front and/or rear doors will open in response to the appropriate hall call button.
[Special]. Select for Cars with all Front and Rear Openings at the different levels] Semi-Selective Operation shall determine which set of doors is to be opened when the car arrives at that landing. Front and rear doors shall not open at the same time.
12. Independent Service:
Actuation of the Independent Service switch shall remove that car from normal group operation, permitting it to respond only to calls registered on car buttons and making the door close operation subject to the Door Close Button. A car operating on Independent Service shall not respond to hall calls. Car and/or hall lantern operation shall be suspended.
A Call Cancel push-button shall be provided on the car operating panel. When the button is activated all registered calls shall be canceled and a traveling car will stop at the next landing.
[Include all paragraphs under Group Features unless elevator is operating as a simplex unit.] Group Operating Features: 13. Zoned Car Parking:
When the cars are parked, they shall be assigned throughout the building to predetermined zones. The lowest zone shall consist of the Main Floor and adjacent floor, above or below, as required to suit building design requirements. The remaining floors shall be divided into nearly equal zones with one car randomly assigned to each zone. The first car entering a zone shall become assigned to that zone. A car may run through an occupied, assigned zone in search of an unoccupied zone in which to park. While there are no calls registered the cars shall remain parked with doors closed.
14. Delayed Car Protection:
Any car that fails to respond to a demand for service within a predetermined time interval shall be removed from group operation. This shall allow other cars in the group to pick up calls previously assigned to the delayed car.
15. Relative System Response Dispatching:
Optimized response to hall calls shall be achieved through use of a relative system response (RSR) time computed for each hall call registered. The computation of each car's RSR time to a call shall be based on, but not limited to, such relevant factors as distance, service to previously assigned car and hall calls, car load, direction, door and car motion status, and coincidence of car and hall calls. In order to even out waiting times and eliminate particularly long waits while maintaining optimal system performance, the weighting of the factors shall vary with system traffic. The car with the least RSR shall have the call assigned to it.
If for any reason the car is unable to respond to a hall call, the call shall be transferred to the car with the next lowest computed RSR.
16. Moderate Incoming Traffic:
When incoming traffic at the lobby floor increases, as indicated by two cars leaving the lobby in the "UP" direction filled nearly to capacity within a pre-determined adjustable time period, cars assigned to upper zones shall be called to the lobby without waiting for a lobby hall call.
Cars shall be automatically dispatched from the lobby when they become loaded nearly to capacity or if not loaded to capacity, shall be dispatched within a pre-determined time after the previous car had been dispatched.
The cars shall continue to operate in this manner until the lobby traffic has been reduced to a predetermined level.
16A. Rotational Selection:
This feature shall provide for the selection of elevators for dispatch at the lobby in a prearranged sequence in the event more than one car is at the lobby at one time.
16B. Variable Interval Dispatching
The assigned car with higher demand shall be dispatched at the expiration of a time interval calculated on the basis of the number of cars available at the lobby, the number of car calls registered in the last three cars to leave the lobby and the estimated round trip time of these three cars. A car that becomes loaded to a predetermined percentage of capacity at the lobby shall be dispatched immediately.
16C. Up Peak Clock Operation [optional]:
This feature shall initiate Moderate Incoming Traffic after a designated Up Peak Clock period begins and one car leaves the lobby loaded to a predetermined percent of capacity. Up Peak Clock shall maintain a group of elevators in this mode for the remainder of the designated Up Peak Clock period.
17. Moderate Outgoing Traffic:
This feature shall provide additional service during periods of heavy down hall call demand above the lobby. When activated, cars assigned to lobby or basement zones shall be dispatched to handle hall call demand above the lobby. Moderate Outgoing Traffic shall commence following the arrival at the lobby of two cars loaded to a predetermined percent of capacity within a selectable time interval and shall remain in effect for the same interval after the arrival of the last car loaded to the predetermined level.
17A. Down Peak Clock Operation [optional]:
This feature shall initiate Moderate Outgoing Traffic after a designated Down Peak Clock period begins and one car arrives at the lobby loaded to a predetermined percent of capacity. Down Peak Clock shall maintain a group of elevators in this mode for the remainder of the designated Down Peak Clock period.
17B. Up Hall Call Bypass [optional]:
During Down Peak Clock operation, any car traveling down with a "non-stop" load shall cause designated cars to bypass up hall calls. The number of cars operating in this bypass mode is adjustable as a function of building traffic. This operation shall remain in effect for the duration of Down Peak Clock operation.
Firefighter’s Service Operation Features: 18. Firefighters' Service Phase I:
When a building smoke sensor or a keyswitch located at the designated return landing is activated, all cars in the group shall perform an emergency return to the designated landing. The return operation shall be in compliance with applicable codes.

Optional general features: 29. Express Priority Service [Optional]
Express Priority Service shall be initiated by a landing key switch at [Enter landing designation(s)]. The car able to respond in the shortest time shall answer the registered call after canceling prior car calls. When the car reaches the landing registering the call, one of the following shall occur:
2) If a car call is entered and the Door Close Button is pressed, the car will serve the car call then resume normal operation. This operation shall be adjustable so that more than one car call may be entered and the car remains in Express Priority Service until no further car calls are present. When no car call is entered within a preset time, the car will close its doors and resume normal operation.
This feature shall include a Priority Service Light in Hall and will activate the "Please Exit When Doors Open" Message Indicator in the car when the car responds to the priority key switch signal.
30. Executive Priority Service [Optional]:
Executive Priority Service shall be initiated by a landing key switch at [Enter landing designation(s)]. The car able to respond in the shortest time shall answer the registered call after answering prior car calls. When the car reaches the landing registering the call, one of the following shall occur:
1)If no car call is entered within a preset time, the car shall close its doors and resume normal operation.
2) If a car call is entered and the Door Close Button is pressed, the car will serve the car call then resume normal operation. This operation shall be adjustable so that more than one car call may be entered and the car remains in Executive Priority Service until no further car calls are present. When no car call is entered within a preset time, the car will close its doors and resume normal operation.
This feature shall include a Priority Service Light in Hall and will activate the "Please Exit When Doors Open" Message Indicator in the car when the car responds to the priority key switch signal.
31. [Optional] Car to Lobby Operation:
Provided at the main floor for each elevator shall be a keyswitch which, when actuated, shall cause the corresponding elevator to make a trip to the lobby (unless it is on a special service operation, in which case it shall make the trip to the lobby as soon as it is removed from the operation). While returning to the lobby after actuation of the keyswitch, the car shall make normal car and hall stops.
Once it has returned to the lobby, the car will park with its doors open, ready to provide normal service; or, if the car is placed on Independent Service and then the Car to Lobby keyswitch is held in the CLOSED position to close the doors, the car's drive unit will be shut down and the car will be locked out of service. It may be returned to normal service by moving the keyswitch to the OPEN position and then de-selecting Independent Service.
32. ADA Emergency Communications [Optional]:
This feature shall provide an "Alarm Received" message indicator in the car operating panel and a [Select <hall> or <lobby>] panel fixture having an "Alarm" message indicator, keyswitch, and buzzer. The message indicator and buzzer in the hall fixture shall be activated by an Alarm Button in the car operating panel. Activating the keyswitch in the hall fixture shall illuminate the "Alarm Received" message indicator in the car.
[Use of this feature requires that the hall fixture or intercom be in a position which is continuously monitored by an attendant who is available to take action when an emergency signal is activated. See Marketing & Sales Circular Letter CDE3 dated May 3, 1993 for a detailed description of features associated with the Americans With Disabilities Act Accessibility Guidelines.] 33. Intercom [Optional]:
Provision shall be made in the [Select <Main> or <Auxiliary>] car operating panel for an integrally mounted speaker / microphone.
34. Standby Power Operation [Optional]:
This operation shall return each car automatically to a designated landing when the system is initially switched to standby power. One or more cars are returned at a time. Preference is given to loaded cars over empty cars in order to reduce passenger waiting times. A car must respond by beginning to move toward the designated landing within a pre-determined time. If a car does not respond, it is automatically placed in a "Not Available" mode while other cars are moved. If a car was not returned to the designated landing on the first try, a second attempt is made. If the second attempt is not successful, the car will remain in a "Not Available" mode and can only be moved by manual means. Once each car has returned to the designated landing, the doors will remain open for a predetermined amount of time.When all cars have successfully returned to the designated landing or have attempted to move twice, automatic selection of the car(s to run on normal operation will occur.
If for any reason a car selected for normal operation under standby power is delayed for 60 seconds, the car will be placed in a "Not Available" mode and another car will be selected for normal operation based on the priorities listed above.
Manual Override of Standby Power Operation is achieved by a manual input for each car via a strip switch. A manually selected car may be run either in a return operation to a designated landing or in normal operation under standby power. If a manually selected car has not yet returned to the designated landing, it will perform this operation first then immediately go into normal operation. If a manually selected car is delayed, no other car can be selected in the group unless it is manually selected.
If car selection is changed by Manual Override while a car is running in return or normal operation under standby power, the newly selected car will not be permitted to run until the car that had been running has stopped, opened its doors, and gone into the Standby Power Wait state.
Door Control Features:
Glide P will use position and derived velocity feedback to implement a closed loop door control. The feedback topology will achieve conformance to the required position and velocity profiles, with optimum running results at all landings.
The Glide P Door Operator is a closed-loop, self correcting door system, so wind and temperature or even minor debris in the sill groove won’t hamper the doors.
The system’s closed-loop control constantly monitors the speed and position of the elevator doors and compared the data to predefined opening and closing profiles.
Closed Loop Control:
The Glide P closed loop control will allow for smooth operation under varying environmental influences such as, temperature, wind, friction, and component variation. It will meet the specified door times and required position and velocity profiles, with consistent running results at all landings.
Opening and Closing Times:
Opening and closing speeds are adjustable. The system will limit closing speed (and hence the time) based on the code requirement of kinetic energy, which depends on the door mass. The code may limit the speed of a heavy bronze lobby door, but at another floor we can move the doors quicker. Glide P has two door closing speed profiles that can be used to improve the system response The heavy & standard door profiles can both used to enhance a system performance.
Limited Door Reversal:
After the doors start to close, if a person or object interrupts one or more of the beams of the Car Door Protective Device, the doors shall stop and reopen to clear the detection zone. Once the opening is cleared, the doors shall immediately resume closing at normal speed.
Door Noise: Door noise will be 50 dBA.
Door control to open doors automatically when car arrives at a landing in response to a normal hall or car call.
Elevator doors shall be provided with a reopening device that will stop and reopen the car door(s) and hoistway door(s) automatically should the door(s) become obstructed by an object or person.
Primary door protection shall consist of a two dimensional, multi-beam array projecting across the car door opening. Under normal operation and for any door position, the system shall detect as a blockage an opaque object that is equal to or greater than 1.3 inches (33 mm) in diameter when inserted between the car doors at vertical positions from within 1 inch (25 mm) above the sill to 71 inches (1800 mm) above the sill. Under degraded conditions (one or more blocked or failed beams), the primary protection shall detect opaque objects that are equal to or greater than 4” (100 mm) in diameter for the same vertical coverage. If the system performance is degraded to the point that the 4” object cannot be detected, the system shall maintain the doors open or permit closing only under nudging force conditions.
Door nudging operation to occur if doors are prevented from closing for an adjustable period of time.
Adjustable Door Dwell Time:
The time interval that elevator doors stand open after a stop shall be independently adjustable for car call stops and hall call stops. A separate door time shall be adjustable for lobby door hall calls.
Advance Door Opening (not available at 350 - 700 FPM):
The car and hall doors shall begin to open while the car is preparing to stop at a landing to answer a call. The distance from a landing at which the doors begin to open shall comply with applicable codes.
If the doors are prevented from closing for a fixed time period, the Car Door Protective Device shall be rendered inoperative, a buzzer shall sound on the car and the doors shall close at approximately half speed and torque. Normal operation shall resume at the next landing reached by the car.
Door Time Open Protection:
If the car doors do not open completely within a predetermined time, the car shall extinguish its hall and car direction lanterns (if provided), sound the in-car alarm buzzer, and shall if part of a group, remove itself from group operation. Then the car shall proceed to the next landing in its direction of travel (or reverse direction from a top or bottom landing) and again attempt to open its doors fully. If the car moves to three consecutive landings without being able to open its doors fully, it shall shutdown with the doors closed.
Door Time Close Protection:
If the Nudging Operation does not completely close the car doors within a predetermined time, the car will extinguish its hall and car direction lanterns (if provided), sound the in-car alarm buzzer, and shall, if part of a group, remove itself from group operation. Then the car shall open its doors fully and again attempt to close them. If the car cannot fully close its doors after three attempts, it shall shutdown with the doors open. Every two minutes the car shall retry closing its doors.
Car & Hoistway Doors
Doors on the car and at the hoistway entrances shall be power-operated by means of an operator mounted on top of the car. The motor shall have positive control over door movement for smooth operation. Each car door shall be provided with a protective device.
An approved positive interlock shall be provided for each hoistway entrance. The interlock shall prevent operation of the elevator unless all doors for that elevator are closed and it shall keep the
hoistway doors closed while the elevator is away from the landing. Emergency access to the hoistway as required by governing codes shall be provided.
[Select the following for ASME/ANSI A17.1 Code] The car door system shall be designed so that the car doors may not be opened more than 4 inches (102 mm) from the inside of the car if the car is outside the unlocking zone of a landing.
