Instruction Manual

一.接线说明Detail Connection Rules

二. 安装说明Installation

1.主机的安装Installation of the main body (Reading Instrument)

指示器的主机可以安装在配电柜的前面板上(参见图1)。

拆卸主机需按下主机壳上的金属弹片（参见图2）。

主机尺寸为：96×48×80mm

开空尺寸为：92（公差：+0.7，-0）×44（公差：±0.5）

The main body cable fixed on the front panel of distribution Cubicle.(See Fig.1).

Press the metal spring piece while removing the main Body(see Fig.2.)

Dimension of main body: 96×48×80mm

Dimension of hole-cut : 92（Tolerance：+0.7，-0）×44（Tolerance：±0.5）mm

2.短路电流传感器的安装Installation of short circuit current sensors

此传感器必须安装在环网供电线路的分支上，必须紧固的套接在被检测的电缆线路防止传感器滑动而造成光纤接口的松动或断裂（参见图3）。拆卸（参见图4）。短路电流传感器的尺寸为：40×43×26mm Each sensor must be installed on each phase of distribution cable line after branching. In order to avoid optical fiber terminals loosening or disconnecting due to sensor slipping, the sensor must be fixed tightly onto cable line.（see Fig.3）Removing (See Fig.4) Dimension: 40×43×26mm.

3. 接地电流传感器的安装Installation of earth-fault current sensor 此传感器安装在三芯电缆上，此传感器的磁轭应将三根导线包围起 来（参见图5）。外形尺寸为: 40×43×26mm

This sensor is installed on the 3-core cable. Its magnetic yoke shall encircuit the whole three conductors (See Fig.5) Dimension: 40×43×26mm

4. 导线的连接（参见图6，7，8）

Connection between sensors and main body. (See Fig.6,7,8)

两种传感器和主机的连线，均应连接紧固，防止松动和脱落。

连接光纤时要确保光纤插入到底，以保证指示器的正常工作。

本产品中的光纤长度标准配置为1.5米，可选配置为2.5米或3.5米 注意：光纤两端截面经过特殊处理，安装者绝不可随意剪短！

Please refer to the label on the main body. In order to ensure the indicator working properly, the connections between the sensors and the indicator must be fixed tightly, and the fiber must be push to the bottom of the sensors and the indicator. For the device, the fiber length options can be 1.5, 2.5, 3.5m or even longer based on user’s requirements.

NOTE: The fiber is not allowed to be cut short by users, as the fiber is specially polished.

三． 操作步骤Operational Procedure

1. 指示器的主机操作步骤Test

按下主机面板上的按钮并持续1秒钟后，主机报警指示灯应闪烁，同时，报警继电器应吸合。当再次按下此按钮时或等待三十秒后，报警状态解除，继电器恢复（参见图9） Press the button in the hole for one second, all of the alarming relays will pick up, and all of the LEDs start shining at same the time. After 30

seconds or press the button once again, the indicator will be on the free test state and then be reseted (See Fig.9)

2. 清除报警：Alarming resetting

当指示器处于报警状态时，按下面板上的按钮，或使用远程复位端子

5和6，均可将指示器复位，使其恢复正常状态。

The indicator can be reset from alarming state to normal state either with button or with remote resetting terminal 5and 6.
