1. Unlock: Hold "SET" button, for 10 sec., until the four LED flash to status of unlock. After unlock, it is back to normal operating mode.2. Lock: It is automatically locked if there is no button pressed in 60 sec. 3. NO/NC Setting: Press DIP switch to set NO or NC.4. Learn mode: Put fork part into the detected medium for 5 sec. and then operate "Unlock". After unlock, hold "LEARN" button for 5 sec., the LED1 ~ LED4 will flash orderly with frequency which is 1 time per sec. to start learning. If the four LEDs are all flash together, this learning is successful; if only the central two LEDs shine, this learning is failed and it is required to learn again.5. Sensitivity setting: Under status of unlock, press "SET" button to set sensitivity with checking the flash of LED1 to LED4. Sensitivity is from high to low by LED1 to LED4.Notice: To enter the second learning mode, please press "SET" button in 3 sec. after first learning finished. Otherwise the user shall be required to process the whole learning mode again to reset the setting. This function is to avoid of the false operation.Notice:1. The learning function of this type is not only to overcome the condition of the vibration absorption after the installation on the wall of tank but also to avoid of false operation caused by noise interference. 2. Factory setting is based on the density of water (1g/cm3). When the density of detected object is higher than or equal to 1g/cm3, it can be used normally without setting learning function. Otherwise it needs to reset learning function when the density of detected object is lower than 1g/cm3. 3. Sensitivity is set as the highest value in the factory and suitable to be used under the stable wave of medium. If the wave of medium fluctuates bigger, it is required to lower the sensitivity to avoid any error in warning.

1. Unlock: "SET" button for 10 secs until alternate red and green lights flash. The unit unlocks and returns to the operation mode. The red and green light stop flashing when "SET" button is released.2. Lock: It is automatically locked when there is no operation within 60 secs.3. NO / NC setting: Under the unlock condition, hold "SET" button for 3 secs and then the alternate red and green lights flash. When the green LED flashes, release the button to enter NO / NC setting mode and then press "SET" button once to adjust the required status.

4. Learning mode: Put the fork part into the detected medium with stability for 5 secs. Under the unlock condition, hold "SET" button for 3 secs and then the alternate red and green lights flash. When the red LED flashes, release the button. The red LED flashes once in a second orderly to express the status of waiting for learning. The red LED flashes and goes out twice to express the status of learning. The learning setting is successfully finished when the alternate red and green lights flash quickly. Otherwise, the red and green light flashes together and the user has to set the learning function again. To reset the learning, just press "SET" button again to enter second learning mode. Notice: To enter the second learning mode, please press "SET" button in 3 sec. after first learning finished. Otherwise the user shall be required to process the whole learning mode again to reset the setting. This function is to avoid of the false operation.Notice:1.

！

► Bore a hole in the pipe or housing wall with the external diameter of the adapter (max. oversize: 0.2 mm). ► If possible, screw a cover plug into the adapter .

2. Welding operation

！The power of the welding device must be adapted to the thickness of the wall.

position for the spanner.2

► Fix the adapter at several points with sufficient holding force. Apply the fixing points at equal distance opposite each other.

► Apply the welding seams between the fixing points opposite each other. Ensure sufficient intervals between the individual sections(cooling phases to avoid glowing through / warping of the adapter due to overheating).

3. After welding

► Let the adapter cool down. ► Clean the thread from welding residues.

2

The welding operation must be carried out by authorised personnel. It must be carried out carefully and according to state-of-the-art technology. During welding and the following cooling phase the sensor must notbe in place. The surfaces must be free from any soiling. Welding tools must be suitable for the adapter and wall material.

►

► Adapter alignment:Tighten the sensor by a spanner until you can feel the end stop (this corresponds to a maximum tightening torque of 35 Nm). Note: Further tightening may affect the sealing effect.

Screw the sensor into the adapter. Avoid damage to the sealing areas.

Note: If the sensor can only be screwed into the thread with great resistance, stop the force. If it is not possible to rectify the thread, remove the adapter and weld in a new one.

横向安装，料位开关上方有挡板(长度约为10"(250mm)，宽度约

为8"(200mm))，可防止(d)物料在料位开关周围的不当堆积，并

可降低物料对于料位开关的冲击。

安装于卸料斗内，料位开关螺牙底端与桶壁之间的最大距离不超

过2.4"(60mm)，可避免因物料的不当堆积而发生误报警的情况。

不正确的安装：

水平安装在填充壁上或进料口下方。

安装角度不正确(振动棒的表面因承受进料和卸料的高负荷压力而

容易出现故障)。

在管道中安装：注意叉体和水流方向，以便开关在管道中正确安装。

正确安装：

顶部安装，振动棒垂直向下，可安装在顶部(远离进料口)的任何

位置。泡沫对料位开关无影响。

横向安装，以減少物料的冲击及挂料现象的发生。

横向安装，料位开关上方有挡板(长度约为10"(250mm)，宽度约

为8"(200mm))，可防止(d)物料在料位开关周围的不当堆积，並

可降低物料对於料位开关的冲击。

安装於卸料斗内，料位开关螺牙底端与桶壁之间的最大距离不超

过2.4"(60mm)，可避免因物料的不当堆积而发生误报警的情况。

不正确的安装：

水平安装在填充壁上或进料口下方。

安装角度不正确(振动棒的表面因承受进料和卸料的高负荷压力而

容易出现故障)。

1、安装时，可将开关以水平向下呈15~20度之夹 安装，以減少 物

料的冲击和掛料现象的发生。

2、安装时应尽可能远离桶槽的进料口以避免物料冲击和誤报警的发

生。如无法避免时，须在进料口与料位开关之间加装隔板保护。

3、接線盒入線口必须朝下，电源線入線口的固定螺母必须锁紧。

4、工作人员於桶槽内工作时，严禁利用振动棒攀爬或悬掛任何绳索

及物品。

1. 前期准备

焊接操作必须由已授权人员进行实施。按照当前技术水平来仔细操作。在焊接和冷却阶段，音叉开关不可移动。表面必须无任何腐蚀。焊接工具必须适合连接件和管壁材料。

！

在管壁或者外壳壁钻一个孔，和适配器的外径一致。(最大超出0.2mm)如果可以，向适配器中拧入一个插头外盖。

2. 焊接操作

！ 焊接设备的功率必须适用於外壁的厚度。

适配器对齐： 旋转标记 到音叉开关正面显示的位置；

扳手标记 供扳手可旋转的位置；

12

用足够的夹持力在某些点修复适配器，在对立面的相同距离应用修覆点。

在修覆点相互对立间应用焊键。在相互独立的区域间保证是有效的间隔（冷却阶段应避免由过热造成的透光或适配器翘曲）

3. 焊接后处理方式

让适配器冷却下来。

清理螺纹焊接残留物。

4. 适用於卫生级音叉开关的焊接式适配器安装方式

用一个扳手将 拧紧,直到感觉已经达到了终点(这与最大扭矩35Nm一致)

註:进一步拧紧将会影响密封圈效果。

开关

将 拧入适配器,避免搅坏密封圈。

注意：若开关拧入螺纹内，並带有很大阻力，不要强迫这种拧法。如果不可能矫正螺纹，去掉此适配器，並且重新焊接一个新的。

开关

检查(A)处与(C)处是否有密封圈,缺一不可安装。

用润滑膏(B)涂抹开关螺纹。润滑膏必须通过应用批准，並且和弹性体的使用相兼容。A
