接入动力电、检测电压 Power connection and voltage detecting  待设备整体固定完成后，接入动力电（3L+1PE）进入总控箱；每根线径不低于 4mm， 材质为铜线。 After the lift is completely fixed, connect power (3L+1PE) into the main control box; each wire diameter no less than 4mm, made of copper wire.  使用万用表检测输入电压是否正常，输入电压不能超出或低于标准电压 10%； Using a multimeter to check if the input voltage is normal; the input voltage can not exceed or lower than the standard voltage of 10%;  电控箱接地需引入地下 1m 以下。 The grounding wire of control box should be 1m underground.  以上完成后，打开电控箱空气开关，观察电压检测显示是否正常，如果数字跳动，则表 示错相，或缺相。 错相解决方案：将输入的三相线中的任意两根互换即可解决。 缺相解决方案：检测三相线是否有一到两根线没有接入。 备注：如没有其他问题，且电控箱正面的电源指示灯为亮起状态，则接线正常，可以使用。 After completing the above steps, turn on the air switch in the electric control box and observe whether the voltage detection displays normal. If the digital jumps, it means there is Mis-phase, or Default phase . Mis-phase solution: exchange position any two of the 3phase wires for input power line. Default phase solution: check and see if there is one or two of the wires not connected to 3phase line. Note: if there is not other problems and the power indicator in front of the electric control box is on, then the wiring is normal for use.

手动测试电机转向 Manual test of motor rotation direction  检查完以上事项后，在电控箱面板处，将运行模式切换到手动状态下，按上\下按钮， 使升降机点动运行，检测运行方向和按钮是否相符，如果上、下颠倒，将电机动力线中 的任意两根，相互调换。 After checking the above items, switch the operation mode to the manual operation on the control box and press the up/down button, lift operated in press and hold mode. Check if the running direction matches the buttons. If the direction is upside down,exchange any two of the three lines for motor power line.

自动运行 Test run and put into use  以上全部功能及问题学习后，即可使用自动运行操作设备。 在电控箱面板处，切换自动模式，使用按钮盒，按动楼层按键，设备将总动运转到相应 的楼层后停止。 After learning all the above functions and notices, you can switch the lift into auto-run operation and put it into use. On the panel of the electric control box, switch to automatic mode, use the control panels on each floor, press the floor button, and the lift will be stopped after running to the corresponding floor.

日常维护 Routine maintenance 1. Examine and maintain the lift weekly or once a month according to the operating frequencies lift. 1) To check the platform connection pin nuts no loose, and falls off. 2) To check the hydraulic tubing no rupture, connectors no leakage and loose. 3) To check the electrical lines no linking, bare. 4) To check all joint of controlling box no loose, the light is working properly. 5) To check the electrical, hydraulic valves block, the control handle, the button operating flexible. 6) To check the switch of the lower and higher limit position no loose, damaged. 7) To check the lubrication state of strut and cylinder pin, handling into enough oil. 8) To maintain the glide path often in lubrication, wheel and the slide no dry friction. 2. Maintain the pit clean, do not have the water and other impurities.
