DMK-4CSA-5 Pulse jet Timer Controller with digital display

The control device adopts a connection terminal of inset and pull type. When circuit board is replaced, it is not necessary to remove all connection leads, but only to pull out the plug so as to save maintenance time.

Manual

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.

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.

Time nixie light 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.

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.

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.

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.

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.

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.

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.
