產品概述 Description
脈沖噴吹控制儀是脈沖袋式除塵器噴吹清灰系統的主要控制裝置。它的輸出驅動電磁脈沖閥，進而控制壓縮空氣對濾袋循序噴吹清灰，使除塵器的運行阻力保持在設定的范圍內，以保證除塵器的處理能力和收塵效率。
Pulse jet control device is a main control device in a jet dust-cleaning system of a pulse bag-house. It outputs driving electromagnetic pulse valve, to control compressed air, to jet dust on the filtration bag in a proper sequence, and to keep the operation resistance to clear dust within the set range, so as to guarantee the processing capability and dust-Collection efficiency of the bag house.
控制儀每次輸出一位的驅動電壓，一個驅動電壓持續時間，稱為脈沖寬度。相鄰二個輸出驅動電壓之間的間隔時間，稱為脈沖間隔。控制儀完成對所有位的電磁閥驅動輸出所需要的時間，稱為脈沖周期。兩個脈沖周期之間的停頓時間，稱為循環間隔。
The control device creates driving voltage output every time. One driving voltage has duration, called a pulse width. The interval time between the two interfacing output-driving voltages is called as pulse interval. The time
necessary for the control device to complete electromagnetic valve outputs of all bits is called as pulse cycle. Pause time between the two pulse cycles is call as cycle interval.
根據除塵器的清灰要求設定控制儀的循環間隔、脈沖間隔和脈沖寬度參數，保證除塵器運行阻力在設定的范圍內。
According to the dust-cleaning requirement of bag house, control device parameters, such as cycle interval, pulse interval and pulse width, are set, to guarantee that the operation resistance of the bag house is within the set range.

使用說明 Manul
1.運行控制： 接上電源后。線路板“停止/運行”輸入端子上若，
（1）外接的觸點沒有閉合，則控制儀停止運行，等待外接的觸點閉合；
（2）外接的觸點閉合，則控制儀開始運行，從第一位開始輸出驅動脈沖閥，經脈沖寬度延時，
停止輸出。再經脈沖間隔計時后移至下一位進行輸出，至終位后停止脈沖輸出，再經循環間隔計時后重新從第一位輸出，進行新的循環。
Run Control：
After power on, the input terminal of “Stop/Run” on the circuit board has the following:
(1)The contact of external connection is not closed, and the control device stops operation, to wait for the contact to close;
(2)The contact of external connection is closed, and the control device starts operation. starts to output driving pulse valve from the 1st digit. After the pulse is delayed by a pulse width, it stops output. Then after pulse interval is time-kept, it shifts to the next digit to output and then to the last digit and pulse output stops. After cycle interval is time-kept, the 1st digit starts to output again, and a new cycle starts.
2.停止方式： 控制儀運行時，當線路板“停止/運行”輸入端子上外接的觸點斷開，有二種停止運行的方式：
（1）線路板上J1的插塊使1、2針腳相連時，控制儀馬上停止運行。當線路板“停止/運行”輸入端子上外接的觸點再閉合后，從停止運行時的下一位繼續開始輸出運行。
（2）線路板上J1的插塊使2、3針腳相連時，控制儀不馬上停止運行，要工作到控制儀最后一位輸出后才停止運行。當線路板“停止/運行”輸入端子上外接的觸點再閉合后，從第一位開始繼續輸出運行。
Stop Mode:
When control device is operating, and if the contact of external connection on input terminal of “Stop/Run” on the circuit board is disconnected, there are 2 stop operation modes:
(1)J1 insert block on the circuit board makes pin 1 and pin 2 joined, and the control device stops operation at once. If external contact of input terminal of “Stop/Run” on the circuit board is closed again, the next digit, from the last time when operation stops, continues output operation.
(2)J1 insert block on the circuit board makes pin 2 and pin 3 joined, and the control device does not stop operation at once, and stops operation until the last digit output of the control device. If external contact of input terminal of “Stop/Run” on the circuit board is closed again, it starts to continue output operation from the 1st digit.
3.數碼顯示： 控制運行時，顯示的是脈沖間隔或循環間隔計時的剩余時間；數碼管閃爍顯示時，顯示的是循環間隔剩余時間；不閃爍顯示時，顯示的是脈沖間隔剩余時間；停止運行時，顯示“0”；參數設定時，顯示的是所設定的參數值。
Number display:
Under control operation, display is the remaining timekeeping of pulse interval or cycle interval; if nixie light display is blinking, the display is the remaining time of cycle interval; if nixie light display is not blinking, the display is the remaining time of pulse interval; if operation stops, the display is“0” when a parameter is set up, the display is the set parameter value.
4.手進輸出： 按動線路板上的“手進”鍵能停止當前的脈沖間隔計時，馬上進行下一位的脈沖閥驅動輸出，這樣可快速依次檢查電磁脈沖閥的工作情況。
Step output:
Pressing “Step” key on the circuit board can stop the current pulse interval timekeeping, to go to the next pulse valve driving output at once. In this way, the working status of the electromagnetic pulse valve can be checked in sequence quickly.
5.最大輸出位數： 控制儀有最大輸出位數選擇短接塊，將J2選擇插塊移至需要的輸出位數插座上，使該位置上下兩針腳相連，即可實現選擇需要的最大輸出位數。
Maximum output digit:
There is a selection short connection block of maximum output digit for control device, to move J2selection insert block to the required socket of the output digit and make the upper and down pins on the location jointed, so as to realize the required selection of maximum output digit.
6.脈沖寬度參數： 按動線路板上“脈沖寬度”處“∨”和“∧”鍵,可使脈沖寬度參數在1～99數字之間調節，該參數單位為10毫秒，相對應的脈沖寬度可調范圍為10～990毫秒。
Pulse width parameter:
“∨”and “∧”key is pressed at “pulse width” on the circuit board, pulse width parameter can be adjusted between digits 1～99. The parameter unit is 10 millisecond,and the adjustable range of the corresponding pulse width is 10～990 millisecond.
7.脈沖間隔參數： 按動線路板上“脈沖間隔”處“∨”和“∧”鍵,可使脈沖間隔參數在1～99數字之間調節，該參數的單位為1秒，相對應的脈沖寬度可調范圍為1～99秒。
Pulse interval parameter:
“∨”and “∧”key is pressed at “pulse interval” on the circuit board, pulse interval parameter can be adjusted between digits 1～99. The parameter unit is 1 second,and the adjustable range of the corresponding pulse interval is 1～99 second.
8.循環間隔參數： 按動線路板上“循環間隔”處“∨”和“∧”鍵,可使循環間隔參數在1～99數字之間調節，該參數的單位為“分”，對應的循環間隔可調范圍為1～99分。
Cycle interval parameter:
“∨”and “∧”key is pressed at “cycle interval” on the circuit board, cycle interval parameter can be adjusted between digits 1～99. The parameter unit is“minute”. Adjustable range of the corresponding cycle interval is 1～99 minutes.
9.參數保存： 當控制儀處于參數修改狀態，停止計時及脈沖輸出。以上三個參數，在第一次按動“∨”或“∧”鍵時，數碼管顯示的是原來的參數值。以后按動后顯示的是改動后的參數值，3秒內沒有按動任何的“∨”或“∧”鍵，則當前改動后的參數值將被保存。控制和顯示返回到參數修改前的狀態，并以修改后的參數來控制運行。在修改某個參數時，可隨時修改另一個參數，保存時所有修改過的參數都被保存。
Parameter saving:
Under parameter modification status of control device, timekeeping and pulse output stops. For the above 3 parameters, when “∨”or “∧”key is pressed for the 1st time, the display on the nixie light is the original parameter value. After afterwards pressing, the display is the modified parameter value; if there is not any pressing “∨”or“∧” key in 3 seconds, the parameter value of the current modified value is saved, and the control and display return to the status before the parameter is modified, and the modified parameter controls operation. When any parameter is under modification, another parameter can be modified at any time and the modified parameter is all saved during saving period.
維護保養 Maintenance
1.控制儀接上電源后，線路板上5V、12V、24V的LED指示燈都不亮，應檢查電源線與接線端子是否松動，電源0.315A熔絲是否熔斷，電源變壓器是否正常、電源部分有無斷線、脫焊等現象。
After the control device is powered on, 5V, 12V and 24V LED indicator on the circuit board is not lit. It is necessary to check if power line is loose with connection terminal, if 0.315A fuse of power supply is broken, if power transformer is normal and if there is any phenomena like a broken line, loose soldering, etc. in the power supply part.
2.若5V或12V的LED指示燈不亮，說明負載發生短路，很可能是個別元件損壞，應逐一檢查，如斷開負載后5V或12V仍不正常，應檢查三端式穩壓電路是否正常。
If 5V or 12V LED indicator is not lit, it shows that there is a short circuit in the load, and some component is damaged. It is necessary to check one by one. If load is disconnected, 5V or 12V is still abnormal, and 3-terminal stabilized circuit must be checked to see if it is normal.
3. 若24V的LED指示燈不亮，一般是負載端電磁脈沖閥及導線引起過載或短路造成的。
If 24V LED indicator is not lit, the general status is that there is overload or short circuit of electromagnetic pulse valve and lead at the load side.
4.控制儀通電后數碼管顯示和按鍵輸入正常：
(1)輸出LED指示燈沒有亮，電磁脈沖閥也不動作，則有可能MCU電路損壞。
(2)輸出LED指示燈亮，而電磁脈沖閥不動作，則有可能相應的電子開關管損壞。
After the control device is powered on, nixie light display and key input is normal:
(1)Output LED indicator is not lit and electromagnetic pulse valve does not work. And it is possible that MCU circuit is damaged.
(2)Output LED indicator is lit and electromagnetic pulse valve does not work. And it is possible that the corresponding electronic switch tube is damaged.
5.若某一電磁脈沖閥常吸，應檢查對應的電子開關管是否漏電、擊穿。
If a electromagnetic pulse valve is always magnetized, it must be checked if the corresponding electronic switch tube is in electric leakage or broken-down.
6.若電磁脈沖閥全部不吸，應檢查閥用公共線端子外的接線是否正確可靠。
If electromagnetic pulse valve is not always magnetized, it must be checked if the connection outside of the terminal of common lead of the valve is correct and reliable.
