Xizi leads the pack of new and updated products for both elevators and escalators.
Noise-Reducing Brakes
With Xizi Noiseless Brakes, working air-gap noise stays below 58dB, reducing air-gap noise by 50% compared with conventional brakes under the same load. The brakes are attached to the outside of the traction machine for easy service and replacement. The integrated brake-releasing limit ensures operational safety in addition to the application of high-quality noise-absorbing elements for more than two million times, and vibration-damping materials for over three million times. The air-gap protection level is raised to IP42, up from IP40. Having undergone more than two million energy-absorption tests, the new brakes promise a desirable, long working life for users.
Upgraded Traction Machine
GETM 3.0R PMS is an upgraded traction machine by Xizi Forward for a velocity range up to 1.75 mps and a load range up to 1000 kg for both MR and MRL installations with enhanced reliability and new features including intelligent temperature control, twin cooling fans to optimize working conditions of the motor, automatically processed stator formation and automatically processed motor windings.
GETM 3.0R, equipped with the newly developed noiseless brakes, combines refined materials with state-of-the-art processing technology, including the automatic wire-winding by machine for higher insulation performance. Additional twin cooling fans start to reduce the motor’s heat accumulation at a preset temperature in order to increase the reliability and worklife cycle of the motor. A service button enables field technicians to inspect or replace the fans easily.
Controls for Escalators
Xizi Escalator Controls (IC/GC series) feature redundancy designs for safety and reliability. The integrated MSC board works by two CPUs and a set of 32-bit memory to achieve eight safety functions, meeting the SIL2 safety perfection level with zero failure rate. The eight functions check against over-speed and respond before the rated speed is exceeded by 20%; against unintentionally reversing travel; whether the braking distance keeps within 1.2 times of the allowed value; whether the secondary brake is functioning properly; against any missing steps and/or comb plates; the handrail belt speed against any deviation greater than 15% from the rated value for more than 15 s.; the opening of the operational brake; and the opening state or removal of any cover plates for service purposes in the truss zone.
The control over the secondary brake allows a power-off delay to prevent the escalator from making any emergency stops that are too abrupt for passengers, while the value setting and self-learning ability makes field installation easy.
BACnet Extends Elevator Bus
Carlo Gavazzi Inc. has launched an extension of its Dupline® two-wire elevator bus, the SBWEB BACnet Gateway. This product enables the company to provide complete solutions in building-automation systems for simplifying field-level wiring. The SBWEB allows Dupline input/output (I/O) modules, sensors and energy meters to be used as remote I/O for direct digital controllers (DDCs). The data is automatically converted into BACnet/IP objects, which most DDCs can access.
The SBWEB gateway can save up to 80% of wiring and installation costs by eliminating multi-conductor “home run” cables from field devices back to DDCs. It collects the signals from analog and digital field devices and sends them over long distances via a simple pair of wires. Since the SBWEB also increases the possible distance between field devices and DDCs, it reduces cost by decreasing the number of necessary controllers.
KLEEMANN Introduces Products
KLEEMANN introduced its Virtual Window and “KLEEMANN-talk2lift” at Interlift 2013 in Augsburg, Germany, last October. The former is the result of a partnership with DigiGage (ELEVATOR WORLD, October 2013), which utilizes modern software and motion-sensing technology to create the feeling of a virtual window within the elevator cabin. The latter is intended for those with special needs or reduced mobility. It enables speech recognition within the cabin that can control the lift by the vocalization of floor number and other keywords.
