DIRECTIONS FOR USE
Safety rules for electrostatic Powder coating
1. This equipment can be dangerous when not operated according
to the following standards:
EN 50 050 (or VDE 0745 Part 100),
EN 50 053 Part 2 (or VDE 0745 Part 102),
and specification sheet, ZH 1/443 Electrostatic Powder Coating.
2. All electrically conductive parts within 5 m of the coating area,
especially the workpieces, must be grounded.
3. The floor in the coating area must be electrically conductive
(normal concrete is generally conductive).
4. The operating personnel must wear electrically conductive foot-
wear (i.e. leather soles).
5. The operating personnel should hold the powder gun in the bare
hand. If gloves are worn they must be electrically conductive.
6. Connect the grounding cable (green/yellow) supplied to the
grounding screw of the electrostatic manual powder coating
equipment. The grounding cable must have a good metal to metal
connection with the powder coating booth, the powder recovery
equipment and the chain conveyor or the hangers of the objects.
7. The electric cables and powder hose to the guns must be laid out
so that they are protected from possible mechanical damage.
8. The powder coating equipment must switch on only after the
powder booth is in operation. If the booth breaks down, then the
powder coating equipment must switch off.
9. The grounding of all conductive parts is to be checked at least
once a week.
10. When cleaning the powder gun and when replacing nozzles the
control unit must be switched off.

EASYTRONIC CONTROL UNIT
Field of Application
The electrostatic EasyTronic Control Unit is designed exclusively for the
controlling powder coating with the EasySelect manual powder gun.
This equipment is not to be used for any other purpose. Any damage
resulting from its misuse is not the responsibility of the manufacturer,
the entire risk is carried by the customer alone.
All settings for efficient powder coating have been made simple and
reproducible on the EasyTronic. The built-in electronics permit exact
setting of the optimum powder output, and the values set can be seen
on the digital display windows and can even be checked from a
distance. According to the selected application mode, the spray voltage
is set automatically and spray current is limited automatically.
The EasyTronic Control Unit can be connected to all usual mains
voltages.
For a better understanding of the relationships in powder coating it is
recommended to read the operating instructions of other components,
thoroughly, so as to be familiar with their functions also.
Operating mode
The EasyTronic Control Unit is foreseen as standard for operation with
all manual coating equipment in the EASY range. The desired
functionality must, however, be determined by means of a "jumper" on
the electronic board inside the control unit. If the control unit is supplied
as a component of an EASY unit, then the "jumper" will be
correspondingly set in the correct position at the factory.
In every other case, it is recommended to check the setting of the
"jumper" (see also the corresponding section "Setting the operating
mode on the electronic board ").
An incorrectly set "jumper" can lead to malfunctioning or to
reduced functioning of the Vibration, Fluidization or Stirrer!
NOTICE

2EasyTronic
Issued 07/02
The operating panel of the EasyTronic control unit consists of 4 main
areas: Diagnostic LEDs, Displays, "+/–" Keys, and Function keys.
1. The Diagnostic LEDs 1–8 serve to show the status of the equip-
ment, and equipment faults. Detailed information is found in the
"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 a key is pressed once, the value is increased or decreases,
respectively, by one step. If a 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.
ITW Gema recommends leaving the electrode rinsing air
switched on, but can, however, remain switched off for
applications with very small amounts of powder.
•Application keys: With these keys the electrostatic (High-
voltage, and current) are automatically set so that the setting
for the selected application is the optimum.
– Settings for flat parts
– Settings for complicated parts with depressions
– Settings for coating parts already coated
High-voltage and current can be deactivated, when the
corresponding key pad with the illuminated LED is pressed for
longer than 1 second.
The EasyTronic control unit is switched on and off with a Push button.
If the equipment is switched on, the yellow lamp is illuminated.
When the equipment is first switched on the preselected factory
settings displayed:
60% 4.0 Nm3/h
Flat jet rinsing Complicated parts
After switching the equipment off (also when the equipment is discon-
nected from the Mains) the actual settings are retained.

powder gun.
6. Plug the injector in, and
connect the powder hose
to the injector and to the
powder gun.
7. Connect the red hose for
the conveying air to the
corresponding output - 1.2

DAILY START UP
a) Setting 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 more information, also 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
being 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 coat-
ing thickness.
The selection takes place with the aid of the + or – keys, 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.
4. Check the fluidizing of the powder
5. Point the powder gun into the booth and press the powder gun
trigger
6. Select the correct electrode rinsing
When using flat jet nozzles:
- Press the key with the corresponding symbol . The LED of the
corresponding key illuminates.
When using round jet nozzles with air rinsed deflector plates:
- Press the key with the corresponding symbol . The LED of the
corresponding key illuminates.
7. Adjust the powder cloud to a test object
When using flat jet nozzles:
- Unscrew the threaded sleeve approximately 45°, so that the flat
jet nozzle (or extension) can only be turned slightly
- Turn the flat jet nozzle to the desired axial position
- Tighten the threaded sleeve again
When using round jet nozzles with air rinsed deflector plates
- Exchange the deflector plate (ø 16, 24, and 32 mm supplied with the
powder gun)

however, do not point it at an object to be coated yet
2. Select the application setting
Press the corresponding application key
on the control
unit. The LED of the corresponding key illuminates.
3. Press the powder gun trigger
4. Coat the object(s)
d) Switching off
1. Release the powder gun trigger
2. Switch off the control unit
The settings for high-voltage, rinsing air, and powder output are
retained.
c) Remote control through the Powder gun
The different functions can be remotely controlled with the aid of the +
and – keys on the rear of the powder gun:
1. Select the application setting
Press the + and – keys on the powder gun simultaneously
Check by observing the LED display on the powder gun:
Red = Flat parts
Green = Complicated parts
Red/Green (alternating) = Spraying over
2. Change the powder output
Press the + or – keys on the powder gun. The powder output is
correspondingly increased or decreased.
