SPRAY / BELL APPLICATOR
TRIGGERING
If you are currently using an RMA-303 dual purge bell
applicator system and want to add the Evolver 303
dual purge 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 10 shows the
recommended 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 dual purge spray applicator system and plans to
use RMA-303 dual purge bell applicators as well.
Figure 10: Conversion Schematic
In Figure 10, the trigger solenoid must be an electroni-
cally 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/bear-
ing 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 P1T/P2T (Paint Trigger) valve. If any of
these solenoids are located inside a hazardous area,
they must be explosion proof.
