Vickers 威格士比例阀英文翻译说明General DescriptionThe power amplifier has five voltage inputs (one inverting) and a current input 0-20mA. Adjustments for set zero point or deadband compensation and for gain allow the amplifier to be easily tuned to the proportional control valve The ramp fnction generator can be switched on and off using the “ramp enable" control.一般的描述功率放大器有五个电压输入(反相)和电流输入0-20mA设置零点或死带补偿的调整，增益 允许放大器容易调谐到比例控制阀，坡度fn功能发生器可以使用“斜坡启用”控制开关开启 和关闭Monitor points on the front panel allowmeasurement of the conditioned command signal, and either of spool position signal or for valves without LVDT) of solenoid current. (“Conditioned command signal” is the input signal modified according to settings of set zero point or deadband compensation, gain and ramp functions.) 在面板上的监视器点允许测量了条件指令信号，以及阀芯位置信号或无LVDT阀的电磁电流。

For effective protection, the user's electrical cabinet, the valve subplate or manifold and the cable screens should be connected to efficient earth (ground) points. The metal 7-pin connector part no. 934939 should be used for the integral amplifier.In all cases, both valve and cable should be kept as far away as possible from any source of electromagnetic radiation such as cables carrying heavy current, relays and certain kinds of portable radio transmitters, etc. Difficult environments could mean that extra screening may be necessary to avoid the interference.警告:电磁兼容(EMC)有必要确保该单元按照本单张所显示的连接安排连接。
对于有效的保护，用户的电气柜，阀 瓣或阀箱和电缆屏幕应该连接到有效的地球(地面)点金属7针连接器部件应该用 NO.934939作积分放大器在所有情况下，阀门和电缆都应尽可能远离电磁辐射的任何来源,如电缆承载着沉重的电流、 继电器和某些种类的便携式无线电发射器等恶劣的环境可能意味着需要额外的屏蔽，以避 免干扰汐ZZ 4币秋5Q说Jb2 - IW;各 mA 爭 22 J5H50mA冲Alarm outjNjIF^iinp adruie ndicalorO^noad EnabledRampsAcc.
