Introduction
Introduction
The Pro Xpc Auto Controller is designed exclusively
for controlling a Graco electrostatic spray gun as part
of a paint coating system.
The controller sends power to the gun power supply,
which increases the voltage to the level set at the
controller. The fluid is charged by the spray gun
electrode. The charged fluid is attracted to the
nearest grounded object, wrapping around and
evenly coating all surfaces.
Controller Features and
Options
• The full voltage setting is 100 kV for solventborne
guns and 60 kV for waterborne guns.
• The controller can be flush mounted at the front
plate or wall mounted. See Mounting, page 14.
The Pro Xpc Auto Controller provides the ability to:
• Display and set the voltage and current.
• Create and store spray presets.
• Operate the spray gun remotely via discrete I/O.
The controller has three interlocks. These interlocks
must be satisfied before the system will operate.
Check and follow all National, State, and Local codes
regarding properly interlocking your spray system.
Also see Ventilate the Spray Booth, page 13.

Pre-Installation Steps
Pre-Installation Steps
Ventilate the Spray Booth
Provide fresh air ventilation to avoid the buildup of
flammable or toxic vapors when spraying, flushing,
or cleaning the gun. Do not operate the gun unless
ventilation fans are operating.
Electrically interlock the controller (B) with the
ventilators to prevent gun operation without
ventilating fans operating. Use the 24 VDC Interlock
pinontheDiscreteI/Ocabletoconnecttothe
ventilator interlock. Check and follow all National,
State, and Local codes regarding air exhaust velocity
requirements.
NOTE: High velocity air exhaust will decrease the
operating efficiency of the electrostatic system. The
minimum allowable air exhaust velocity is 60 ft/minute
(19 linear meters/minute).

signals. Systems can be designed to integrate from
1 signal up to all 19 signals. The examples in this
manual describe a basic integration (6 I/O signals
used) and a complex integration (all 19 I/O signals
used).
Discrete I/O input signals are only monitored
if the Pro Xpc Auto Controller has been
placed in the Discrete I/O mode. See
Setup Screen 2 (Discrete I/O Select), page 41.
See Signals, page 20 for available signals.
Isolation
The discrete I/O interface signals are isolated from
circuit ground. Isolation is required to prevent
disturbance of the measurement of the spraying
current.
NOTE: The isolation is not designed to isolate
hazardous potentials.
I/O Grounding
Pins 8, 12, and 17 are the I/O Ground pins. Connect
a ground from each connecting device to one or more
of these pins. This will match the potential of the Pro
Xpc Auto Controller and the connecting device.
R MOT Input Operation
In order to accept remote input commands from the
discrete I/O interface, the following conditions must
be met:
• The discrete I/O interface must be selected by
setting Parameter P02 = 1.
See SetupScreen2(DiscreteI/OSelect),page41.
• The REMOTE Enable input, on the Discrete I/O
cable, pin 4, must have 24VDC (logical “1”) applied
to it to select REMOTE mode.
Connect the desired input signals. During REMOTE
input operation, error confirmation is the only local
input (using the keypad) possible.
NOTE: Values for presets P001 – P003 must be set
up prior to entering REMOTE mode. Preset P000
istheonlypresetwhichcanbealteredusingthe
Discrete I/O cable signals when the controller has
been placed in REMOTE mode. Presets P004 - P250
are not accessible in REMOTE mode.
R MOT Output Operation
Connect the desired signals. Digital output signals
are generated unconditionally. Analog output signals
require 24VDC on Analog Output External Power (pin
16) on the discrete I/O Interface cable.

The values for Presets P001–P003 must be entered locally, using the keypad, prior to
placing the controller in REMOTE mode. It is not possible to change the values of these
Presets remotely.
Presets P004–P250 are not accessible in REMOTE mode.
