一般情况下，电梯按先上后下的原则安排运送乘客的次序，规定在运行方向确定之后，不响应中途的反向呼唤要求，直到到达本方向的最远站点才开始返程。
轿厢的启动与运行轿厢在运行方向确定且轿厢门已关好时启动运行，运行的初始阶段是加速运行阶段，其后是稳定运行阶段。
轿厢的平层与停车轿厢运行后需确定在哪一层站停车，平层即是指停车时，轿厢的底与门厅“地平面”应相平齐，一般有具体的平层误差规定，如平层时两平面相差不得超过5mm。
合理的结构设计，严格的选材，精良的生产加工，严格的质控程序，保证产品在实际应用中效果良好。

AC电源AC输入型PLC的输入接线AC电源AC输入型PLC的输入接线这种类型的PLC（基本单元和扩展单元）采用AC100～120V供电，该电压除了供给PLC的电源端子外，还要在外部提供给输入电路，在输入接线时将AC100120接在COM端子和开关之间，开关另一端接输入端子。
扩展模块的输人接线扩展模块的输入接线由于扩展模块内部没有电源电路，它只能由外部为输人电路提供DC24V电压，在输入接线时将DC24V正极接扩展模块的24＋端子，DC24V负极接开关，开关另一端接输人端子。
Purpose: the self-supporting non-filled cable is suitable for the urban and township telecommunication lines of local telecommunication network, and also for the special network lines connecting to the public network. It is economical and practical to use the same outer protective layer for hoisting line and cable. The mechanical and electrical properties of the cable remain unchanged under conditions of 30~C - 60~C. Structure: wire: annealed bare copper wire, copper wire diameter is 0. 4, 0. 50, 0. 60, 0. 70, 0. 80, 0. 90 mm. Insulating material: high density polyethylene or ethylene-propylene copolymer. The color of the insulated wire is in accordance with the full chromatographic standard. Pair of insulated wires: two different colored insulated wires are twisted in pairs according to different pitch and are identified by a specified chromatographic combination. Core structure: with 25 pairs as the basic unit, more than 25 pairs of cables are assembled according to the unit, each unit is wired with the unit of specified chromatogram to identify different units. 100 pairs or more of cables plus 1% of the reserve pair. Core tape: wrap with a polygrease film tape. Shielding: the two sides are overlapped with or without corrugated metal strip, beyond the cable core of the longitudinal capsule. The plastic film coated on the surface of the shielding belt and the bonding sheath of the protective layer: black low density polyethylene. Hoisting line: the hoisting line is 7 strands of galvanized steel strand, nominal outside diameter is 6. 3 and 4 mm. The tensile strength of two types of 75mm is not less than 3000kg and 1800kg respectively. The suspension wire is coated with thermoplastic paint to prevent the steel wire from corrosion. Identification and length marking
Allowable bending radius of cable laying and installation: non-armoured layer cables shall not be less than 6 times of the outer diameter of the cable; The armoured or shielded cable shall not be less than 12 times the outer diameter of the cable. The soft cable of shield layer structure should not be less than 6 times the outer diameter of the cable.
