OTIS SKY
Since giving rise to the elevator industry more than 150 years ago, Otis has been at the forefront of elevator technology. Through the years, Otis team of professional engineers and designers initiated nearly every major advance and breakthrough in the industry. Being the latest in a long line of reliable products, the SKY System is built on the concept of excellence in safety and performance. With the new permanent magnet (PM) gearless machine and the latest generation of Otis intelligent microprocessor controllers, the SKY System simplifies maintenance procedures and reduces energy consumption. High in operation performance and superior in ride quality, the SKY System is the ideal solution for a wide range of commercial and residential buildings. Features: 1 Permanent Magnet (PM) Gearless Machine 2 Controller and Drive 3 Governor 4 Door Control System
PM Gearless Machine Permanent Magnet (PM) Gearless Machine The SKY System is one of the first elevator systems to use a permanent magnet gearless machine, replacing the induction motor with the traditional worm gear arrangement. The absence of the frictional resistance of machine gears allows the SKY System to economise on energy consumption costs and minimise overall environmental impact. Passengers will not experience the vibration and noise generally associated with geared machines. Additionally, the reduction of moving parts in the PM gearless machine results in reduced mechanical wear and tear. ACD Controller Reliable Controller Designed for groups of up to four cars, the modular controller incorporates a new generation of printed circuit boards and software to provide optimal response times. The digital closed-loop Variable Frequency (VF) drive, with vector control technology, further increases efficiency and accuracy, and a digital speed encoder ensures correct car speed and positioning. The result is a system of exceptional reliability. Speed Time Profile Optimised Speed Profile As the elevator moves through the hoistway, car locations are monitored and precisely measured to ensure that the elevator is guided to the registered floor at its optimum speed profile. A closed loop control system enables floor levelling within five millimetres. This control mechanism not only saves energy, but also ensures a safe and comfortable ride. An Economical Solution When a hall button is pressed, Otis Relative System Response (RSR) dispatcher instantaneously selects the most eligible car in the elevator group to answer the call. In a split-second, the RSR dispatcher analyses a set of parameters based on response time estimates and ideal group control practices. By maximising system performance, RSR enables passengers to benefit from dramatically reduced waiting times.
LAMBDA LC Door Protection Device Otis LAMBDA LC infrared curtain door protection system casts an invisible safety net of beams across the elevator entrance. The door protection device scans with more than 70 infrared beams per second, in a response time of less than.1 second. If the system detects an obstruction, the doors swiftly and smoothly open to avoid any contact. Door Systems designed to meet varied passenger demands Door Systems Otis offers different door systems to configure to the building s passenger demands. The car and landing doors are driven by a direct current (DC) permanent magnet motor. A speed encoder mounted on the operator axis controls the doors opening and closing positions. This allows accurate and smooth operation, enhancing the system s safe performance. For higher traffic applications, a closed-loop VF door operator is available. It allows flexibility in adjusting and setting door operation, meeting a variety of different operating profiles to suit the building s needs.
Standard Features Control Cut-off Hall Call Switch When activated this feature disables all hall calls, but allows the normal operation of car calls. When the car has no further demand, it parks with its doors opened at the last landing served. Full Collective Operation Registered car and hall calls are answered in the order in which the landings are reached. The direction of travel is established by the first registered car command or hall call. Load Non-stop When a car is loaded to a predetermined percentage of capacity, weight-sensing devices are activated, causing the car to bypass further hall calls. Separate Car and Hall Call Door Times The time that an elevator door remains open after a stop differs between hall and car calls. Generally, more time is needed for a car to respond to hall calls. Communication Alarm Bell on Car When an alarm button is pressed, the buzzer on top of the car will be activated. Car Position Indicator This feature displays car position, running direction, fire service and overload signals. Hall and Car Direction Indicator The elevator running direction is displayed by LED segments. Hall Position Indicator This feature includes a 16-segment LED position and direction indicator. Comfort Extra Door Time This feature extends the length of time the doors remain open. Emergency Emergency Car Light Unit To ensure the minimum lighting requirement in a car, a rechargeable emergency supply will automatically switch on if the normal lighting supply fails. Safety Door Time Protection When the doors fail to open or close, the elevator will remove itself from group control, retry to open or close its doors and sound the buzzer in the car. After three unsuccessful attempts, the car will be shut down. Motor Protection Device When the temperature of the motor exceeds a designated value, the elevator will shut down automatically. Misuse Prevention Anti-Nuisance Car Call Protection When the weight of passengers in the car is not more than 10% of rated car duty, and four or more car calls are registered, all car calls are cancelled automatically. Car Call Cancellation When a car call button is incorrectly selected, it can be cancelled by pressing twice on the same button. Nudging If the doors are prevented from closing for a fixed period of time, a buzzer sounds and the doors begin to close at a reduced speed. Service Failure Auto Diagnosis The controller detects and records the elevator s operation status automatically. If failure occurs, this function will help minimise maintenance time.
Optional Features Control Advanced Door Opening Attendant Service Operation Independent Service Parking and Shutdown Operation Two-Four Cars Group Operation Control To improve performance time, the doors will begin opening as the car approaches a landing. By activating this switch located in the COP, the car can be manually operated, independently from other cars in the group. By activating this switch in the COP, the car will be disconnected from the group, permitting it to respond to registered car calls independently. When this feature is activated, the car will discontinue serving any hall or car calls. After responding to the last car call, the car will go to a designated floor and shut down. The elevator control system can handle two to four cars in a group. This feature will dispatch cars to respond to calls according to traffic status and relevant service requirements. Communication Car Chime CCTV Cable When the car arrives at a landing, the chime on top of the car will be activated as an arrival tone. A video cable can be provided to connect a CCTV camera in the car to the machine room. (Video camera and monitoring device not supplied by Otis) Comfort Door Hold Button Fan (Manual) Second Car Operating Panel The elevator doors will remain open for a specified period of time if this button is pressed. A manual switch in the COP controls fan operation. A Second Car Operating Panel can be installed in the car for more convenient passenger floor selection. Emergency Delayed Car Protection Emergency Fireman Service Top of Car Emergency Exit When the doors are prevented from closing or the car does not respond to assigned hall calls, the delayed car will be removed from group operation and its doors will close. This feature automatically places the car at the designated return landing with the doors fully open; the fireman can then enter and manually operate the elevator. The emergency car top exit can be manually opened from the outside and used for the rescue and evacuation of passengers.
