Graco Air Controllers are labeled with the same
reference letters as the applicator, for easier
matching.
NOTICE
NOTICE NOTICE
Use filtered air to prevent contamination of the
paint finish and to prevent damage to the air
bearing. Air that is not adequately filtered can clog
bearing air passages and cause bearing failure.
The ProBell Rotary Applicator Manual contains
detailed filtering specifications.
Note
For the turbine air (TA), bearing air (B),
shaping air inner (SI) and shaping air outer
(SO) lines, use 8 mm (5/16 in) OD tube with
1 mm (0.04 in) wall. For the bearing air return
(BR) and the three triggers (DT, PT, and ST),
use 4 mm (5/32 in) tube.
NOTICE NOTICE NOTICE
Take great care to connect the air lines to the
correct ports. Incorrect air line connections will
damage the applicator.
1. Connect all nine required air lines to the
applicator first. See your applicator manual for
instructions.

5. Connect the main air supply line into the main air
fitting (MA, Ref. 7) on the side of the box.
Note
Once the air is applied, it will flow freely
out Port B. The controller has no option
to turn this air off. (Manual Controller

Connect Communication Communication Cables
Connect Connect Communication
The air controllers (Manual or Electronic)
communicate to the rest of the system over Graco
CAN cables. Each component and the power supply
must be on the Graco CAN network. The best
connection pattern depends on whether the Air
Controller is electronic or manual.
1. Connect a Graco CAN cable from the system
logic controller (DD) to the electrostatic controller
(EE) or directly to the electronic air control (BB)
for non-electrostatic systems.
2. If the power supply is attached to the Air
Controller, install the termination resistor (201)
on the splitter inside the box.
Note
If the Air Controller was purchased as
part of a system, the termination resistor
will be installed at the factory. If not, the
resistor comes with the power supply.
3. Manual Air Controller:
a. Connect a Graco CAN cable from the power
supply (AA) to the right (inside) port on the
Air Controller (BB).
b. Connect a Graco CAN cable from the
other port on the Air Controller (BB) to the
Electrostatic Controller (CC).

4. Electronic Air Controller (with Speed Controller):
a. Connect a Graco CAN cable from the power
supply (AA) to the lower/rear port on the
Speed Controller (EE).
b. Connect a Graco CAN cable from the Speed
Controller (EE) to the Air Controller (BB).
c. Connect a Graco CAN cable from the Air
Controller (BB) to the Electrostatic Controller
(CC).
