F5 门是由带垂直排列的滑动轮的齿带传动，门机由于垂直驱动轴而垂直安装在门头上，轿门由齿带操纵完成往复运动，因此省去了所有的附加操作元件。F5 doo

Door No:Date:Page:Original:ITSA-TD-2044/012004/09/275 of 6-10U driven by gear belt, car door is recurrently moving, thus obviating auxiliary components.F5 门机采用无齿轮交流异步电动机，变频器控制，其工作原理为，电子控制装置依据运行时间曲线计算门的位置，给出最佳运行速度。门控制器给出特定运行时间
6、曲线控制门的运动。运行时间曲线没有振动的限制，所有的运行时间参数取决于开门、关门、强迫关门和再开门操作的调整。Adopting gearless AC asynchronous motor, F5 door operator is controlled by frequency inverter. The mechanism of F5 door operator is as follows: electrically controlled device will determine door position based on running time curve, outputting o
7、ptimum running speed. Door control will output specific running time curve to control door movement. Running time curve is not limited by vacillation; all running time parameters are decided by the settings of door-open, door-close, door-nudge and door-reopen. 门机自动检测门是否到达终端位置并发出各自的终端位置信号给电梯控制系统，然后在各
8、自的控制信号作用下给出可微调的终端位置转矩。Door operator will automatically test whether door has reached terminal position and give off individual terminal position signal to lift control system, later output terminal position torque which can be find-tuned under the effect of individual control signals. 门保持在一定的终端位置可调节
9、范围内，给电梯控制系统的终端位置信号保持有效，不考虑相应信号是否发出，这种情况就好像终端位置开关一样。Door will remain in adjustable range of definite terminal position. Terminal position signals to lift control system will remain effective no matter whether corresponding signals have been sent or not. This circumstance is as the same as that of ter

According to
13、 safety regulations, all landing door locks should be in parallel connection with control circuit (all sub landing door electrical lock must be in parallel connection with this circuit). Only when all landing doors are closed and interlock hook is anchored with lock housing hook with engagement dept
14、h more than 7mm, door interlock electrical contact can be connected. 所有楼层厅门的门锁电气触点都接通以后，电梯的门回路接通，电梯才能启动运行；当任何一层厅门未关好，或关上后锁钩啮合不符合深度要求，致使电气接头未接通，电梯都将不能运行。After door electrical contacts of all landing door are closed, lift door circuit will be closed, so that lift can start moving. If any landing door
15、is not closed or hook engagement is not deep enough, electrical contact will not be closed, making lift unable to start moving. 厅门在门锁的作用下平时是紧闭着的，只有当轿厢到达某一层站并达到平层位置时，这一层的厅门才能被轿门上的开门刀拨开，否则，在电梯厅门外面就无法将门打开。 对于某些电梯，为了维修方便，生产厂家给每层厅门上都安装了三角钥匙锁，由电梯专业检修人员在某层的厅门外面用特制的三角钥匙可将厅门打开。图 5 门联锁装置No:Date:Page:Original:ITSA-TD-2044/012004/09/2710 of 6-10U otherwise, door can not be opened outside landing door. For some lifts, to facilitate maintenance, lift manufacturers equip each landing door with triangular key lock by which qualified technicians can open landing door outside a certain landing.
