Introduction
About this Manual
Valco Cincinnati has prepared this manual as an aid for installing, operating, and servicing the VC3500 control.
This manual provides specific information about the unit, and general guidelines and references when discussing
other equipment such as glue systems, scanners, encoders, and dispensing valves.
If you need more information, please contact your Valco Cincinnati representative.
Product Description
Valco’s VC3500 is a sophisticated microprocessor control that provides precise adhesive delivery. The control can
be designed for either two-channel, two-valve applications or four-channel, four-valve applications.
The VC3500 is used for applications where consistent glue patterns are required at high machine speeds and during
speed changes. The VC3500 provides complex glue patterns that can be difficult or impossible to obtain with other
systems. The control operator can use the control’s front-panel touch-screen to edit glue patterns while the parent
machine is operating.
The VC3500 features a user-friendly, multi-language display; multiple pattern placement; speeds of up to 2000 feet
(610 m) per minute; internal flow control; and optional RS-232 communications with external devices. The VC3500
control can store up to 99 fully programmed jobs.

General Information
It is the purchaser’s responsibility to ensure that all local, county, state, and national codes, regulations, rules, and
laws relating to safety and safe operating conditions are met and followed.
The best safeguard is trained personnel. The purchaser is responsible for providing personnel who are adequately
trained to install, operate, and maintain Valco components and systems.
This section contains information that is essential to the safety of personnel. Safety information is included through-
out the rest of the manual as well. The following safety conventions are used to indicate potential safety hazards:
Warnings
All personnel involved with the installation, operation, and maintenance of the equipment must read and thoroughly
understand the following warnings:
WARNING! Promptly repair or replace all worn or damaged electrical wiring
and equipment wires to avoid danger to personnel.
WARNING! Properly route all electrical wires to avoid danger to personnel
and damage to moving parts of machine.
WARNING! Disconnect all power before opening the control. Only qualified
personnel should open and service the control.
WARNING! This symbol indicates the presence of un-insulated dangerous
voltage within the product’s enclosure. This voltage may cause electrical
shock or fire. Failure to observe precaution may result in death, personal
injury, and/or equipment damage.
WARNING! This convention is used to alert the user to important installation,
operation, and/or maintenance information. Failure to observe precaution
may result in personal injury or death.
CAUTION! This convention is used to alert the user to important installation,
operation, and/or maintenance information. Failure to observe precaution
may result in damage to equipment.

WARNING! When making adjustments or performing checkout procedures,
stay clear of any moving mechanical parts and do not touch exposed electri-
cal equipment or electrical connectors.
WARNING! Keep pump cover and electrical enclosures closed except during
setup,service, andcheckout procedures.
WARNING! Promptly repair or replace all worn or damaged parts.

Routing Low-Voltage Leads
When routing low-voltage leads, follow these guidelines:
•Do not route low-voltage leads in the same conduit as wires carrying a high-current load.
•Do not route low-voltage leads adjacent to, or across wires carrying a high-current load. If low-voltage
leads must cross or run parallel to wires carrying high current, keep the leads at least 6" (152 mm) from
high-current wires.
•Do not splice or solder leads.
•Trim leads to the required length. Leads should be only as long as necessary for installation.
•All wiring should be in conduits or wireways.
Connecting the Supply of Electrical Power
Electrical connections should be made only by experienced service per-
sonnel!
The control must be connected to a “clean” supply of electrical power. Use a dedicated circuit if possible—if a
dedicated circuit is not available, donot connect the control to a circuit that supplies high-amperage equipment. Use
another circuit such as a lighting circuit.
General Wiring Guidelines
Electrical installation should be accomplished only by experienced service
personnel!
