DESCRIPTION OF FUNCTION
Main compressed
air connection
The arrows always show the direction of flow
Figure 2
The fluidized powder in the powder hopper is sucked into the injector
by means of the conveying air (1- red hose). The powder/air mixture
reaches the powder gun through the powder hose (2). The powder is
electrostatically charged at the nozzle of the gun. In addition, an elec-
trostatic field is created between the gun nozzle and the grounded
object. The charged, and sprayed powder adheres to the surface of the
object.
The powder is fluidized by air forced through a porous plastic plate
from below. The powder acquires, thereby, fluid-like characteristics.
The conveying air, supplementary air, and rinsing air are set on the
control unit, and the fluidizing air is set on the fluidizing unit (3) on the
rear side of the control unit. The functioning of the injector is described
in the EasyFlow injector operating instructions.

areas: Diagnosis LEDs, Displays, "+/–" Keys, and Function keys.
1. The Diagnosis LEDs 1 – 8 serve to show the status of the
equipment, and equipment faults. Detailed information is found in
Chapter "Troubleshooting guide".
2. There are two Displays with whose help the following values are
displayed:
•Powder output (Setting range 0 – 100 %) Powder output in
% always refers to the max. possible output volume to the
total air volume setting.
•Total air volume (Setting range 1.6 – 6.0 Nm3/h)
3. The Keys "+" and "–" are for setting the powder output, and the
total air volume used.
If the Key is pressed once, the value is increased or decreases,
respectively, by one step. If the Key is pressed continuously, the
setting change rapidly.
4. The Function keys have the following functions:
•Electrode rinsing air for flat jet nozzles
•Electrode rinsing air for round jet nozzles
When a Key is pressed once, the corresponding function is
activated, and the corresponding LED illuminates.
If a Key with an illuminated LED is pressed for longer than 1
second, the function is deactivated.

DAILY START UP
A) POWDER FLUIDIZING
The fluidizing of the powder is dependent on the type of powder, the
humidity of the air and the ambient temperature. The fluidizing func-
tions with the switching on of the control unit.
Proceed as follows:
1. Release the clamp holding the cover, and lift off (complete with
the injector, and the venting hose) from the powder hopper.
Take care that the suction tube is not damaged.
2. Slowly increase the fluidizing air on the fluidizing air unit (9)
The powder should only “boil” lightly, but evenly. If necessary,
stir the powder with a stick.
3. Replace the cover and refasten the clamp.
B) REGULATING THE POWDER OUTPUT, AND POWDER CLOUD
The powder output is dependent on the powder, and the setting of the
total air volume.
1. Switch on the control unit
2. Set the total air volume (For further information see the EasyFlow
Operating Instructions)
The total air volume is dependent on the powder hose length, the
number of turns of the hose, the hose diameter, and the object
to be coated.
The value set for the total air volume can be left as it is, as long
as the same powder hose is used. If the hose length and/or the
hose diameter are changed, then the total air volume must be
reset.
3. Select the powder output volume according to the desired
coating thickness.
The selection takes place with the aid of the Keys + and – either
on the control unit or on the rear of the powder gun.
To start, a standard setting of 60% is recommended. The total air
volume is maintained constant automatically.
