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 13.
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 12.
Installation Options
Installation details vary widely depending on the
system requirements. This section shows three
typical installations. They are not actual system
designs. For assistance in designing a system to suit
your particular needs, contact your Graco distributor.
Installing and servicing this equipment requires
access to parts which may cause fire, explosion,
electric shock or other serious injury if work is not
performed properly.
• Do not install or service this equipment unless
you are trained and qualified.
• Be sure your installation complies with national,
state, and local codes for the installation of
electrical apparatus in a Class I, Division 1, or a
Group II, Zone 1 Hazardous Location.
• Comply with all applicable local, state, and
national fire, electrical, and other safety
regulations.

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
pin on the Discrete I/O cable to connect to the
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).

Discrete I/O
Discrete I/O
The controller can accept up to 19 I/O interface
signals. Systems can be designed to integrate from
1signaluptoall19signals. Theexamplesinthis
manual describe a basic integration (6 I/O signals
used) and a complex integration (all 19 I/O signals
used).
See Signals, page 19 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: Theisolationisnotdesignedtoisolate
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.
RE OTE 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,page36.
• 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 – P250 must be set
up prior to entering REMOTE mode. Preset P000
is the only preset which can be altered using the
Discrete I/O cable signals when the controller has
been placed in REMOTE mode.
RE OTE 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.

Use to signal detection of an error condition.
0: No error condition detected.
1: An error condition has been detected and reported.
NOTE: Reset by Error Reset input or by local confirmation.
8Ground
I/O Ground
Reference potential for I/O interface signals.
9 Analog Input
Current Setpoint Input
Use to set the current setpoint (µA) nominal value. The REMOTE current setpoint
input applies when Preset 0 (P000) is selected and the controller is in REMOTE
operation.
The input voltage or current is used to create a relational output current value for
the gun electrostatics power supply. The larger the input value, the greater the
electrostatics current setpoint.
0 – 10V (received input) ➔ 0 – 150µA (desired gun output)
OR
4 – 20mA (received input) ➔ 0 – 150µA (desired gun output)
The type of input is selected on SetupScreen3,page36
10 Analog Input
Voltage Setpoint Input
Use to set the voltage setpoint (kV) nominal value. The REMOTE voltage setpoint
input applies when Preset 0 (P000) is selected and the controller is in REMOTE
operation.
The input voltage or current is used to create a relational output voltage value for
the gun electrostatics power supply. The larger the input value, the greater the
electrostatics voltage at the gun.
0 – 10V (received input) ➔ 0 – max V* (desired gun output)
OR
4 – 20mA (received input) ➔ 0 – max V* (desired gun output)
The type of input is selected on SetupScreen3,page36
* max V = 100 kV (solventborne) or 60 kV (waterborne)
