If you are currently using an RMA-202 bell
applicator system and want to add the Evolver 202
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 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 202
spray applicator system and plans to use RMA-
202 bell applicators as well.

In Figure 7, the trigger solenoid must be an
electronically 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 ITW P/N 11678-
01. An additional solenoid must be used to activate
the P1T (Paint 1 Trigger) or P2T (Paint 2 Trigger)
valves. If any of these solenoids are located inside
a hazardous area, they must be explosion proof.
