The advantage of permanent magnet synchronous traction machines for elevators
(1) low wear. traction machine for elevators, the biggest advantage is that there is no transmission structure, in addition to the rotor shaft (it is also a traction axis) on a set of bearings, never any mechanical wear, no wear and tear, the natural extension of the drag lead the life of the machine. (2) energy-saving. The gearless traction machine because there is no transmission structure, there is no mechanical power loss, relatively speaking, it saves energy and running expenses. Load 1000kg elevator speed of 1.00m / s VVVF elevators, for example: OTIS gear traction machine (the traction ratio 1:1) need to 11kW; Weber gearless machine (traction ratio of 2:1) Just 6.7kW. (3) ease of installation. Drag wheel is fixed directly to the shaft of the motor, compact structure and small size, light weight, ease of lifting and transportation, on-site installation will be easier and more still load 1000kg, elevator speed 1.00m / s VVVF elevators, for example:OTIS gear traction machine 17CT, weight 1300kg; Weber gearless machine the WEB-1.0-1000, weight 300kg. (4) running smoothly. The absence of transmission structure, there is no belt drive lost turn, slip, elevator leveling of high precision, reliable operation; there is no gear noise and vibration, and thus the performance of the lift running smoothly, low noise, which is Elevator green revolution the salient features. (5) fuel efficient. Gearless traction machine Since no transmission structure, it eliminates the need for traditional deceleration box lubricants, only a sufficient amount of grease in the bearing memory. Daily lubrication replacement cumbersome Maintenance does not exist, and also to avoid the pollution lubricant leakage and maintenance difficulty, but also saves the lubricating oil costs. (6) is easy to use. Gearless traction machine for elevators with no liquid lubricants, there is no leak, not only there is no pollution, and can be any gesture installation, such as bottom-up hanging at the roof of the hoistway.

The fault of OTIS elevator pcb RCB-II
1.An elevator at runtime to not open the door of the flat layer, MCB board DIF lamp is not lit, replace the MCB board.
2. Elevator Express uplink normal, Parking Express under the parking not flat layer (just start) to replace the MCB board.
3. Elevator after closing is not running, the inside of the door panels minor relay sound, MCB board of DIF indicator does not light, the the door machine communication signal is lost, the replacement of the MCB board.
4. RCB-II board no lights, the MCB board OCF lights, unplug and RCB-II communications, OCF lamp has been lit, the power supply is normal, J5 normal power source, RCB-II board J2 normal, replace the RCB-II board MCB.
5. RCB2 board is powered, all outbound calls does not work, replace it.
6. Elevator outgoing call display highest downlink arrows, replace RCB2 board.
7. Elevator no display, the directive can not be registered. GL1 lights RCB2 panel does not light a 8.1 replace RCB2 board, check the thermal circuit, such as thermal circuit barrier, MCSS digital tube display a three-phase poor contact phenomenon of O 2, check the motor, such as poor inverter CURREUT FEEDBACK error (including the UDX contact) check motor three-phase insulation, if you have any questions, inverter CURRENT FEEDBACK SUM error check MCSS DBSS chip if there is poor contact phenomenon 5, DBSS internal failure.
9.The elevator car Dashboard the COP layer selection signal is not registered, the driver Elevator normal, replace the MCB board after normal.
10. DBD loop barrier: DBD the loop static when barrier, the elevator the MCSS display 0, for example, C relay normally closed contact does not make sense.

Working Principle of elevator safety light curtain
Elevator safety light curtain system is a newly developed set before the light curtain technology and price of the director of the manufacturers of high quality automatic control products, the use of the infrared scanning probe technology. Transmitting means and receiving means mounted on both sides, the internal microcontroller and a microprocessor controlled digital program, so that the infrared transceiver unit is formed in the high speed scanning mode, the infrared light curtain guard barrier, when people and objects into the light curtain barrier region, The control system quick conversion output level signal, so that the load operation, when the purpose of the people and objects leaving a light curtain guard zone, the load normally closed automatically, so as to achieve secure. Practical application of elevator safety light curtain controller is not required, only a transmitter and receiver, used by air plug socket or cable connection, the output can be directly the external various types of computer digital interface.
As shown in the figure is a safety light curtain detects an object (such as the hand) to enter the test schematic structure diagram. The figure, one side of the light curtain equidistantly mounted a plurality of infrared emission tube, the other side corresponding to the same number of the same ordered infrared receiver, an infrared-emitting tube corresponds with a corresponding infrared receiver, and is installed in the same a straight line. When the infrared emission control on the same line, there are no obstructions between the infrared receiver, infrared emission tube emitted modulated signal (light signal) can reach the infrared receiver. Infrared receiver to the modulation signal is received, the corresponding internal circuit outputs a low level, while in the case of obstacles, the infrared emission tube issued by the modulated signal (light signal) does not successfully reach the infrared receiver tube, then the infrared receiver The tube does not receive a modulation signal, the corresponding internal circuit output is high. When no object through the light curtain, all infrared emission tube issuing a modulated signal (light signal) can successfully reach the corresponding infrared receiver of the other side of the tube, so that all internal circuits output low. Thus, by analysis of the state of the internal circuit can detect the presence or absence of the information of the object.
Infrared transmitter and receiver of the safety light curtain path number theoretical maximum of 215, taking into account the spacing between the actual light curtain height and the vertical passage, and generally not more than 48.
