Ransburg Evolver 303 Solvent Applicator A11976-XXX - Manual (Page 25)

SPRAY / BELL
APPLICATOR
TRIGGERING
If you are currently using an RMA-303 bell ap-
plicator system and want to add the Evolver 303
spray applicator system to spray using the same
tubing bundle, a simple conversion must be made
in order to allow for switching between spray and
bell applicators. Figure 7 shows the recommend-
ed system that should be placed in the bearing
air line between the main air input and the robot
manifold plate. It is suggested that this circuit
be placed on the robot arm. This system should
also be used when the user is implementing the
Evolver 303 spray applicator system and plans to
use RMA-303 bell applicators as well.
Figure 7: Conversion Schematic
In Figure 7, the trigger solenoid must be an elec-
tronically activated, normally closed valve with
exhaust, or a 3-way valve, with 100 psi max.,
24VDC. Typically this solenoid already exists in
the robot arm and can be used in this circuit. The
spray applicator trigger/bearing air select valve
must be a pneumatically activated, normally open
solenoid. A suggested solenoid is P/N 11678-01.
An additional solenoid must be used to activate the
PT (Paint Trigger) valve. If any of these solenoids
are located inside a hazardous area, they must
be explosion proof.
