Warning: Electromagnetic Compatibility (EMC) 警告：电磁兼容性（EMC ）

It is necessary to ensure that the valve is wired up in accordance with the connection arrangements shown in this leaflet. 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.

必须确保阀的配线符合本文件中所示的连接布置图。为了有效保护，用户的电气柜、阀的底板或集管以及电缆屏蔽线应被连接至有效的接地点。金属７针引脚连头部件编号为934939应用于整体放大器。

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.

在任何情况下，阀和电缆都应尽量远离任何电磁辐射源，例如带强电流的电缆、继电器和某些便携式无线电发射机等。困难的环境指需要附加屏蔽以避免干扰。

For p/Q control with automatic switch-over, connect d16 to z2 (+10V). 对于自动切换的p/Q控制，连接d16至z2 (+10V)。 The flow command signal (Q) is applied to the feed-forward input, d8, and the desired pressure setpoint voltage applied to a

command signal input (b6/8/10 or z6/8/10). The pressure feedback sensor is connected to the sensor input d2, or d6 as required.

流量指令信号（Q ）适用于前馈输入，d8，预期压力设定点电压适用于命令信号输入（b6/8/10或者z6/8/10）。按照要求，压力反馈传感器与传感器输入d2或d6相关。

The pressure control loop will override the flow command to limit the pressure to the level determined by the pressure setpoint voltage. Adjust P, I and D gains for best performance. 压力控制回路将超控流量指令来限制由压力设定点电压控制的液面压力。调整P 、I 和 D 增益，以取得最优性能。

The switches D3, D4 and D5 belong together. They limit the I output volts between 100% (10V) and 5% (0,5V) as follows:

开关D3、D4和 D5合成整体。它们限制I 输出电压在100% (10V) 和 5% (0,5V)之间，如下：

Reconfiguration of Controller

控制器的重新配置 Parameters 参数

Once the controller parameters have been optimized and set, they can be measured by means of an ohmmeter.

一旦优化及重新设定控制器参数，可用欧姆表测量。 This allows easy reconfiguration of the controller on different cards for use as spare parts or on standard machine series.

这使得不同电路板上的控制器可简单地被重新配置，用作备用零件，或用于标准机器系列。

Four test points are located on the PID-module for this purpose, see diagram for locations. The

resistance between the appropriate test point and ground (at the front panel monitor point) determines the controller parameters:

为此，四个测试点位于比例积分微分模块上，位置见图表。适当的测试点和地面（在前面板监测点上）之间的电阻决定了控制器的参数： P = P-gain／P-增益 I = I-gain／I-增益 D = D-gain／D-增益

Application Notes 应用说明

Operation of the Integrated Test Mode 综合试验方法的操作

The basic operation of the hydraulic actuator can be tested by using the 3-position mode switch mounted on the front panel. To select different modes the toggle switch must be lifted slightly before turning it to a new position. 可使用安装于面板上的3位模式开关来

测试液压致动器的基本操作。在将拨动开关 转至一个新位置前，必须将拨动开关轻微提 升，以选取不同模式。

Caution 注意：

Before setting the mode switch to either “Test valve” or “Test loop” make sure the test potentiometer is set to “0”.

在设定模式开关至“测试阀”或“测试 回路”之前，确保测试电位计设为“0”。 Otherwise sudden movements of the actuator may occur.

否则致动器可能会突然移动。

The mode switch has three positions: 模式开关有三个位置： AUTO 自动

The controller operates in closed-loop mode, using the external command signal. The test potentiometer is disconnected.

控制器在闭路模式下操作，使用外部命 令信号。不连接测试电位计。

TEST VALVE 测试阀

An open-loop command signal for the valve comes directly from the

potentiometer. The external input signal is disconnected. The hydraulic part of the system may be tested in this configuration.

阀的开路命令信号直接来自于电位计。不 连接外部输入信号。系统的液压部分可在 此配置中进行测试。

TEST LOOP 测试回路

The closed-loop command signal for the PID-controller comes directly from the potentiometer. The external signal input is disconnected. This configuration allows for verification of the valve polarity and the control parameters.

比例积分微分控制器的闭路命令信号直接 来自于电位计。不连接外部信号输入。该 配置考虑了需确定阀的极性和控 制参数。
