U402 流量式閥位指示器 V010

1、 RDFK Hydraulic Valve Remote Control System USER MANUAL For For Flow Meter Position Indicator 5. 0 現(xiàn)場調(diào)試 由于現(xiàn)場液壓管路的長度及 被控制的閥門直徑大小不同， 需要 在現(xiàn)場實(shí)地進(jìn)行如下調(diào)試 注意： 在現(xiàn)場調(diào)試前，必 須檢查全部液壓管路的清 潔， 以免液壓管路內(nèi)的垃圾 和其他雜質(zhì)進(jìn)入指示器或 電磁閥， 使系統(tǒng)不能正常工 作。 在調(diào)試前首先要將液壓管路 內(nèi)的空氣盡量排除。 同時(shí)按著 S1 / S2 通電, 開 機(jī)初始化。 按一下 S3 鍵進(jìn)入設(shè)定 A 模 式， L1 燈閃亮，顯示當(dāng)時(shí)計(jì) 數(shù)值。 操

2、作該閥門，使其完全關(guān)閉， 按一下 S1 鍵，清零計(jì)數(shù)值， L1 燈常亮。 再操作該閥門，使其完全開 啟， 按一下 S2 鍵， 將當(dāng)時(shí)的 計(jì)數(shù)值存儲，作滿度值，右側(cè) 八個 LED 燈亮。 用萬用表測量 全開啟是否是 20mA 輸出，如 果電流不準(zhǔn)， 可以通過調(diào)節(jié)內(nèi) 部電位器. 再按一下 S3 鍵， 設(shè)定補(bǔ)償修 正值，本值僅是參考值，用于 補(bǔ)償由液壓系統(tǒng)延遲引起閥 門繼續(xù)轉(zhuǎn)動的角度， 若補(bǔ)償不 足可加大。 再按三下 S3 鍵， 顯示狀態(tài)經(jīng) 過 L1-L11 交叉閃亮后，回到 顯示液壓閥百分比狀態(tài)， 此時(shí) 因?yàn)殚y門全開，所以 L1-L11 全亮，顯示 100%開啟度。 最后， 可反復(fù)操作液壓控制閥

3、U403 10 V0. V0.1 10 .08 .02 20 2010 10. 08. 5.0 Site adjusting Due to the deferent pipe length and the deferent diameter size of valves, it is necessary to adjust this indicator again on site as follows: Note: Before adjusting on site, it must check with the cleanness of all hydraulic pipe lines in

4、order to avoid the refuse and other impurities in the pipe lines coming into the indicator or the solenoid valve and thus the system cannot function properly. First remove the air in the pipe lines as far as possible before adjusting. Switch on power supply after pressing pushbuttons of S1 and S2 si

5、multaneously for initialization of start up. Enter setting mode A by pressing S3 , meanwhile LED lamp L1 lights with flashing to display current count value. Operate this valve to make it full closed, then press S1 to clear count. Now the LED L1 is lighting steady. Operate this valve again to full o

6、pen position, then save current count value as full scale value by pressing S2 , meanwhile 8 LEDs on right side light. After that measuring the output current of full scale to see if it is 20mA output. If this current is not correct, it may adjust the inner potentiometer on PCB to calibrate. Press S

7、3 again to set compensation value. Note that this value is only for reference value which used to compensate the angle of valve continuous moving caused by delay effect of hydraulic system. Compensation may be increased if insufficient. Press S3 again, LEDs now show the valve position indication at

8、the form of percentage after L1-L11 cross flashing. At that time the valve is located at full opened position, all of L1-L11 light to show 100% opening degree. 1/30/11 10 of 12 第 10 頁 共 12 頁 RDFK Hydraulic Valve Remote Control System USER MANUAL For For Flow Meter Position Indicator 的全開啟和全關(guān)閉操作， 檢驗(yàn) 閥

9、位指示器的準(zhǔn)確性， 正常后 斷電待用。 U403 10 V0. V0.1 10 .08 .02 20 2010 10. 08. Finally, repeated operation the valve with full open and full close action to check the veracity of valve position indictor. Switch off the power supply and the indicator is ready for use after indication is normal. 60 常見故障分析： 6.1 液壓控制閥

10、開度指示器 與閥門實(shí)際位置不一致 如果用應(yīng)急操作手動泵對液 壓遙控閥門操作后， 閥門的開 啟度改變， 使實(shí)際的閥門開啟 度與指示的不一致。此時(shí)， 僅 僅需要將該閥門從全關(guān)閉 全開啟全關(guān)閉， 操作一個周 期， 該指示器就恢復(fù)原來正常 的工作狀態(tài)。 同樣， 當(dāng)液壓管路壓力卸壓后 斷電， 當(dāng)管路壓力重新達(dá)到工 作壓力，上電后，也會使實(shí)際 的閥門開啟度與指示的不一 致。 僅僅需要將該閥門從全關(guān) 閉全開啟全關(guān)閉， 操作一 個周期， 該指示器就恢復(fù)原來 正常的工作狀態(tài)。 如果操作后還不能夠消除故 障， 參見第 4 節(jié) “調(diào)試及設(shè)定” 的方法，對該指示器重調(diào)試。 6.0 Troubleshooting: 6

11、.1 The indication of indicator is deferent from valve actual position The position indication shall be differed from valve actual position after hydraulic valve was emergency operated by the hand pump and therefore the valve opening degree was changed. In this case, the valve should be operated for

12、one cycle from full close to full open and from full open to full close again, the position indicator will be recovered to original normal working condition All the same, when the pressure in the pipe line re-applies to working pressure and switch on the power supply again after relieving the pressu

13、re of the hydraulic pipe and switch off the power supply, it is only necessary to operate the valve for one cycle from full close to full open and from full open to full close again, the indicator will be recovered to normal working condition. .If the faults is still existed after above operation, i

14、t is necessary to re-adjust the indicator according to section of “4.0 Adjusting and setting”. 6.2 閥位顯示停止不動 首 先 打 開 面 板 ， 按 一 下 S3 鍵，開啟閥門，查看顯示屏上 指示燈（脈沖）是否變化。 如果沒有變化，再打開線路 板，觀察下面齒輪是否轉(zhuǎn)動， 如果不轉(zhuǎn)動說明齒輪被卡住。 拆開清除齒輪上的垃圾再試。 6.2 The valve position indication does not change First open the front panel, press S3 and the switch on the valve. Check the LEDs (pulses on the display panel to see whether it is changed or not. If there is no change, and then open circuit,
