SWITCHING ON THE SPRAY GUN
The spray gun is switched on via the superordinated control unit of the system. At the
same time the high-voltage and the coating material supply are activated.
7.4
SWITCHING OFF THE SPRAY GUN
The spray gun is switched off diff erently depending on the type of powder injector. In most
cases this process is performed by the control of the coating system.
Note:
On each interruption to work, the spray gun should be blown through (purged) and
powder residue removed. In this way powder deposits and a surge the next time the spray
gun is switched on can be largely avoided.
If a manual switch-off is required and provided that the powder injector is not suitable for
the automatic purging mode, please proceed as follows:
Procedure:
1.
The atomization air has to remain open to prevent powder from penetrating into the
atomization air channel and the cascade compartment during the purging process.
Switch off the powder feed and the high-voltage generation.
2.
If you do not want to modify the settings of the feed and dosage air to continue
coating with the same powder cloud, remove the powder injector from the injector
connection of the powder container. When switching on again no more powder will
be delivered.
3.
Switch on again the powder feed to blow out any powder remaining in the spray
gun.
4.
The powder feed can now be switched off .
7.5
SWITCHING OFF THE SPRAY GUN IN THE EVENT OF FAULTS OR EMERGENCIES
In the event of faults or emergencies the spray gun together with the system can
be switched off by means of the emergency stop equipment. At the same time the
high-voltage and the coating material supply are switched off .
