测试装置适用于控制和功能测试带集成电子装置、工作电压为±15 V或+24 V的比例伺服阀。
运行模式
外部运行 → 将控制柜的工作电压和指令值接入阀
内部/外部运行 → 通过测试仪预设指令值；工作电压由控制柜提供
内部运行 → 通过独立电源装置提供工作电压；通过测试仪预设指令值
通过 BNC 插座预设指令值 → 工作电压可选
注意：
测试装置仅可由熟悉装置、阀及液压系统的人员使用。采用相应设置时，装置会忽略系统控制信号，从而使控制侧原有安全防范失效。
对于操作不当造成的损坏，不承担责任。
根据阀所需工作电压，测试装置可采用+24 V或±15 V供电。调试前必须相应设置“power selector”电源选择开关。
内部 DC/DC 转换器产生所需的 ±15 V 辅助电压，供内部指令值预设使用。
“power selector”电源选择开关还会将内部参考电位L0切换至相应的外接地电位。
开关位置“+24 V”→ 输入插针 B = 参考电位
开关位置“±15 V”→ 输入插针 C = 参考电位
连接
输入接头 ES（1）及 4 mm 输入插孔：左侧输入接头 ES（1）用于连接来自控制器或控制柜的电缆。根据操作元件的设置（参见操作及显示元件），左侧 4 mm 插孔直接连接至输入接头 ES（1）的插针，因此可在插孔处测量控制器输入的全部信号。测试仪和阀运行时，必须具备所需的 +24 V 或 ±15 V 工作电压，具体取决于阀型。若控制柜侧尚未提供工作电压，可在输入接头 ES 处连接相应电源装置。
输出插座 AB（16）及 4 mm 输出插孔：右侧输出插座 AB（16）用于连接阀。右侧 4 mm 插孔直接连接至输出插座 AB（16）的插针，因此可在插孔处测量所有往返于阀的信号。借助短接插头，可分别断开连接电缆中的任一导线，例如用于测量电流。
BNC 插座：可通过标准 50 Ω 电缆将外部产生的指令值信号输入 BNC 插座。此时，指令值选择开关“setpoint selector”应置于“BNC”位置。
PE 插孔：PE 插孔直接连接至输入接头 ES（1）的 PE 端子。输出插座 AB（16）不设 PE 连接。

注意事项：
不带使能输入的运行模式：采用集成电子装置、工作电压为 +24 V 且无使能输入的阀，以 C 端子作为阀实际值的参考电位。此时，“enable”使能开关应置于“off”位置。
带使能输入的运行模式：采用集成电子装置、工作电压为 +24 V 且带使能输入的阀，以 B 端子作为阀实际值的参考电位。此时，“enable”使能开关应置于“on”位置。
