Preparing the spray gun
80351709 - PEM-T3 03/2008
• Connect the spray gun to the Tribo current measuring or display module with the electrical
cable.
• Connect the powder hose to the spray gun and to the powder injector.
• Connect the hose for Tribo air to the spray gun and to the control unit.
2.3 Grounding
For safety reasons, the spray gun must be properly grounded. This occurs through the
electrical cable.
0203_ .doc
Good grounding of the workpiece is also necessary for optimum powder coating.
A poorly grounded workpiece causes:
• dangerous electric charging of the workpiece
• back-spray onto spray gun and user
• uneven coating
• very bad wrap around
Warning
Sparks between workpiece and conveyor hooks (hangers) can occur if hooks or
other hanger parts are not completely cleaned!
These sparks can cause heavy radio frequency interference.

3. Working with the spray guns
3.1 Start up the spray gun
• Switch on the control unit.
• Select the type of gun Manual and charging Tribo on the control unit.
• Refer to the operating instructions of the control unit for this.
Caution
To reduce wear, the total of feed air and dosage air must range between
3.5 - 6 Nm3/h!
The total of feed air, dosage air and Tribo air should not exceed a maximum of
7.5 Nm3/h!
• Hold the manual gun in the spray booth, press the trigger and set the powder volume and
the powder speed to a test piece by adjusting the volume of feed air and dosage air.
• Only open the Tribo air until a Tribo current reading of 3 µA is attained.
Caution
The Tribo air must be reduced or shut off if the Tribo current (charging current) exceeds
3.5 μA!
The charging current depends on the type of powder used and should ideally lie between
2.5 and 3.5 μA.
3.2 Switching off the spray gun
The spray gun is switched off in different ways, depending on the type of powder injector.
Hint
The spray gun should be blown through (flushed) and cleaned from powder deposits
with every interruption of work. In this way powder deposits and surges on switching
on again are to a great extent avoided.
0302_.doc
The flushing procedure can be set on the control unit if the spray gun is connected to an
EPG-D1 or a Control unit Bravo in conjunction with the PI-F1 powder injector. In this case the
spray gun is blown free of powder as soon as the trigger is released.
If the spray gun is operated with an EPG 2008 control unit and a PI-P1 powder injector,
proceed as follows:
• Release the trigger on the spray gun so that the powder feed and high voltage generator
are switched off.
• Set the knob for the overall air quantity on the control unit EPG 2008 to maximum. No more
powder will be delivered when switching on again.
• Press the trigger on the spray gun so that the spray gun is blown free of powder.
• Switch off the control unit and secure against inadvertent switch on.
