Main Page Air/Powder Ratio Control Segments
Picking the second option which is the Controlling via Air Flow, the user will see the below icons on the segments, Powder Transfer
Air and Assistant Air Flows will be set independently. This method is mostly used on Manual System Configurations.
Suggestion:
For the best surface finishing in automatic systems, it is best to adjust the air flow with Ratio Control.
Info:
Air Flows can be selected from C1-4 parameter and also can be seen as Nm
3
/h lt/min.
Info:
Air Flows Control mode (as explained on installation) can be adjusted with C1-3.
The E-COAT Corona type powder gun includes High Voltage output the tip of the nozzle, powder output nozzle and nozzle air. This
nozzle air can be adjusted. It should be noted that every other nozzle types’ optimal adjustment values are different. Nozzle air
adjustment can be made from the second page of the interface from the first segment. Like the other air adjustments the user
can also see the values in Nm
3
/h or lt/min.
Nozzle Air Adjustment Segment
Suggestion:
As Factory Preset, for the Flat type nozzle groups the Nozzle Air Flow is set to 0,2 Nm 3 /S, for the Circle type and
Deflector type nozzle groups it is set to 0,5 Nm
3
/S.
Correctional Factor Adjustment:
On the E-COAT Master configuration screen, C2-1 and C2-2 includes two different powder ratio correction factors. One of the
correction factors is to adjust the minimum powder level and the other one is to synchronize the system if there is more than one
control unit available for use. The first parameter adjustment is 4.0 Nm 3 /S of total air and the powder ratio is %0 while there is
10gr of powder output. This ensures a better curve on the powder ratio control graphic and removes the “dull” zone. The second
parameter is needed because of the multiple gun usage and the different sizes of the gun hoses in the automatic systems. C2-2
removes the possibility of different flow output rates on different guns in the same system thus a better surface finish.
The user should follow the procedure below when adjusting the correction factors.
The user should follow the procedure below when adjusting the correction factors.
1.
If the Air Control mode is not on Ratio Control type, the device should be changed to Ratio control. Press and hold the B1
interface button on the Main Page for 5 consecutive seconds and reach the Calibration Pages. Adjust the C1-3 parameter to 0
(zero) then press B1 button again to get back to the Main Page.
2. On the Main page the Total Air Flow should be adjusted to 4.0 Nm
3
/h or 67 lt/min.
3. Press and hold the B1 interface button on the main page and reach the Calibration page again.
4. Press the B2 interface button and reach the Calibration Page -2 where C2-1 and C2-2 parameters are located. You will need
a filter type powder bag to measure the powder weight output from the spray gun.
5. Put the powder bag at the tip of the gun.
6. Press the trigger for a whole 60 seconds and stop the trigger.
7. Release the bag from the tip of the gun and weight it.
8. The ideal weight should be between 10g and 15g, if the weight is below 10g increase the C2-1 parameter and if it is more than
15g decrease it.
