Warnings
WARNING
Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When
these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific
hazard symbols and warnings not covered in this section may appear throughout the body of this manual where
applicable.
ELECTRIC SHOCK HAZARD
This equipment must be grounded. Improper grounding, setup, or usage of the system can cause
electric shock.
• Turn off and disconnect power at main switch before disconnecting any cables and before
servicing or installing equipment.
• Connect only to grounded power source.
• All electrical wiring must be done by a qualified electrician and comply with all local codes and
regulations.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component. See Technical Specifications in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Specifi-
cations in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete
information about your material, request MSDS from distributor or retailer.
• Do not leave the work area while equipment is energized or under pressure.
• Turn off all equipment and follow the Pressure Relief Procedure when equipment is not in use.
• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine
• manufacturer’s replacement parts only.
• Do not alter or modify equipment. Alterations or modifications may void agency approvals and create safety hazards.
• Make sure all equipment is rated and approved for the environment in which you are using it.
• Use equipment only for its intended purpose. Call your distributor for information.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not kink or over bend hoses or use hoses to pull equipment.
• Keep children and animals away from work area.
• Comply with all applicable safety regulations.
BURN HAZARD
Equipment surfaces and fluid that is heated can become very hot during operation. To avoid severe
burns.
• Do not touch hot fluid or equipment.
4 334784G
Warnings
WARNING
SKIN JECTION HAZARD
High-pressure fluid from dispensing device, hose leaks, or ruptured components will pierce skin. This
may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgi-
cal treatment.
• Do not point dispensing device at anyone or at any part of the body.
• Do not put your hand over the fluid outlet.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Follow the Pressure Relief Procedure when you stop dispensing and before cleaning, checking,
or servicing equipment.
• Tighten all fluid connections before operating the equipment.
• Check hoses and couplings daily. Replace worn or damaged parts immediately.
MOVING PARTS HAZARD
Moving parts can pinch, cut or amputate fingers and other body parts.
• Keep clear of moving parts.
• Do not operate equipment with protective guards or covers removed.
• Equipment can start without warning. Before checking, moving, or servicing equipment, follow the
Pressure Relief Procedure and disconnect all power sources.
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent fire and explosion:
• Do not use solvent-based adhesives that can create an explosive atmosphere when processed.
• Use equipment only in well-ventilated area.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic
drop cloths (potential static sparking).
• Keep work area free of debris, including solvent, rags and gasoline.
• Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes
are present.
• Ground all equipment in the work area. See Grounding instructions.
• Use only grounded hoses.
• Stop operation immediately if static sparking occurs or you feel a shock. Do not use equipment
until you identify and correct the problem.
• Keep a working fire extinguisher in the work area.
334784G 5
Warnings
WARNING
TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or
swallowed.
• Read Safety Data Sheets (SDSs) to know the specific hazards of the fluids you are using.
• Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.
PERSONAL PROTECTIVE EQUIPMENT
Wear appropriate protective equipment when in the work area to help prevent serious injury,
including eye injury, hearing loss, inhalation of toxic fumes, and burns. Protective equipment includes
but is not limited to:
• Protective eyewear, and hearing protection.
• Respirators, protective clothing, and gloves as recommended by the fluid and solvent
manufacturer.
PRESSURIZED ALUMINUM PARTS HAZARD
Use of fluids that are incompatible with aluminum in pressurized equipment can cause serious
chemical reaction and equipment rupture. Failure to follow this warning can result in death, serious
injury, or property damage.
• Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or
fluids containing such solvents.
• Do not use chlorine bleach.
• Many other fluids may contain chemicals that can react with aluminum. Contact your material
supplier for compatibility.

Overview
Overview
InvisiPac pattern control systems can be integrated with InvisiPac systems or stand alone with any other equipment.
For all installations, the advanced display module (ADM) is used to make programming easy.
PC-8 controllers operate in time or distance mode without an encoder. Up to 8 guns and 4 independent triggers are
supported.
PC-8e controllers include the same features as PC-8 with the addition of distance based control using an encoder,
and run up control using an I/P or V/P pressure regulator.
Features of the PC-8 and PC-8e:
Feature
Gun outputs
Trigger inputs
Encoder
Run up control
Program storage
PLC enable / disable
PLC alarm output
PLC program select

Connect Electrical Cord
Improper wiring may cause electric shock or other
serious injury if work is not performed properly.
Have a qualified electrician perform any electrical
work. Be sure your installation complies with all
National, State, and Local safety and fire codes.
The equipment must be grounded to reduce the
risk of electric shock. Improper grounding can
cause electric shock. Grounding provides an
escape wire for the electric current.
The pattern controller system is equipped with a ground
terminal. Have a qualified electrician ground the system
using this terminal.
Electrical power enters through the smaller cord grip on
the right side of the enclosure (see figure). The power
cord can be further secured inside the enclosure with
the provided zip-tie and tie mount.
Installation - External Models
2. Connect earth ground to the grounding terminal.
3. Verify that the cord grip securely tightens around the
power cord. Use a wrench to tighten, if necessary.
1. Install power wires (L1/L2 or L/N) into terminals 2
and 4 on the disconnect switch. The switch accepts
solid or stranded 12 AWG and 14 AWG wire. For
ratings, see Technical Specifications, page 64.
NOTE: The power switch housing can be removed
for easy wiring using the red tab on top of the
switch.

Wire Pattern Control Board
Encoder Installation
(PC-8e only)
1. Connect up to two encoders to monitor line speed.
NOTE: Line 1 and line 2 on the ADM.
NOTE: Encoder type must be quadrature differential
line driver (RS422). Scaling is entered in the
encoder setup screen using the live calibration feature.
NOTE: Some encoders have Z and Z’ connections.
These are not used and do not need to be connected.
Run Up Installation (PC-8e only)
1. Connect up to two “I/P” or “V/P” run-up air pressure
regulators to vary pump pressure based on line
speed. Hardware automatically detects whether an
I2P or V2P is connected.
NOTE: Pressure vs. line speed settings are entered
on the run-up setup screen. See Run Up Control,
page 42.

NOTE: Encoder direction can be reversed by swapping A and A’ with B and B’. Do this is the line speed
reads negative on the ADM.
