SWITCHING ON THE AUTOMATIC GUN

The automatic 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 AUTOMATIC GUN

7.4.1 SWITCHING OFF IN NORMAL OPERATION

The automatic gun is switched off differently depending on the type of powder injector.
In most cases, this process is performed by the coating system controller.
Note:
For each interruption of work, the automatic gun should be blown through (flushed) 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 the automatic gun should be switched off manually and the powder injector is not
suitable for automatic flushing mode, please proceed as follows:
Procedure:
1. The atomizing air has to remain open to prevent powder from penetrating into the
atomizing air channels and the cascade compartment during the flushing process.
2. Switch off the powder feed and high voltage generation.
3. If the settings of the feed and dosing air should not be changed, in order to continue
coating with the same powder cloud, remove the powder injector from the injector
connection of the powder tank.
4. When switching on again no more powder will be delivered.
5. Switch the powder feed on again to blow out any powder remaining in the gun.
6. The powder feed can now be switched off.

7.4.2 SWITCHING OFF THE AUTOMATIC GUN IN THE EVENT OF FAULTS OR EMERGENCIES

In the event of faults or emergencies the 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.
