Valco Cincinnati has prepared this manual as an aid for installing, operating, and servicing the VC350A Flexoseal®
control (Figure 1). 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, contact your Valco Cincinnati representative.
Product Description
The VC350A Flexoseal® system is an electronically controlled lap-gluing system. Using an enclosed glue system,
the Flexoseal®equipment applies accurate glue patterns to inside or outside laps at speeds of up to 2000 feet per
minute (610 meters per minute). The VC350A applies adhesive directly to the product through glue valves. The
valves deliver a precise, uniform application of adhesive through the system’s fluid-flow-control component. The
VC350A Flexoseal® system is used on corrugated box board processing equipment to produce high-quality seals.
The VC350A Flexoseal®system consists of three main components:
•VC350A control—Control boards, encoder
•Glue delivery system—DD-1 pump, air filter/regulator, glue filter, glue-pressure regulator, gauge, and
gaugeprotector

What to Do if Contact with Hot Adhesive Occurs
WARNING! The heat that is contained in hot-melt material will continue to
penetrate and deeply burn the skin unless rapidly cooled by external means
such as water. Do not attempt to remove set hot-melt adhesive from the skin.
OTHERWISE, PERSONAL INJURY COULD OCCUR.
If hot adhesive comes in contact with the skin, do the following:
1. Immediately immerse the contacted area in clean, cold water.
Note! It is recommended that a source of clean, cold water be provided near the hot-melt
work area.
2. Cover the affected area with a clean, wet compress and see a physician immediately.
What to Do if Adhesive-Related Fire or Explosion Occurs
During the heating and melting process, the surface of the adhesive will be exposed to air. The mixture of polymer
fumes and air can catch fire if the hot-melt is overheated.
WARNING! Poor ventilation, smoking, and open flames can cause overheated
hot-melt to ignite. Adequate ventilation must be provided. Smoking should
be prohibited in the immediate vicinity of the molten adhesive. Open flames
must be kept away from the area around molten adhesive. OTHERWISE,
DEATH, PERSONAL INJURY, OR DAMAGE TO EQUIPMENT COULD OCCUR.
WARNING! Exposed arcing may ignite the fume/air mixture. Shield all electri-
cal equipment from melt fumes to avoid exposed arcing. OTHERWISE, PER-
SONALINJURY OR EQUIPMENTDAMAGE COULD OCCUR.
WARNING! Do not use a water extinguisher to extinguish the fire! OTHER-
WISE, PERSONAL INJURY OR EQUIPMENT DAMAGE COULD OCCUR.
If the hot-melt adhesive ignites, promptly perform the following steps:
1. Sound a fire alarm.
2. Evacuate the immediate area.
3. Turn off all local electrical equipment at the source.
4. Fight the fire in one of the following ways:
•Smother the fire with a fire blanket.
•Aim a CO2fire extinguisher at the base of the flames.
•Aim a dry-powder fire extinguisher at the base of the flames.

Section 3—General Wiring Guidelines
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
WARNING! Electrical connections should be made only by experienced
service personnel! OTHERWISE, DEATH, PERSONAL INJURY, OR EQUIP-
MENTDAMAGECOULD OCCUR.
When connecting the supply of electrical power, follow these guidelines:
•Connect the control to a “clean” supply of electrical power. Use a dedicated circuit if possible.
Note! If a dedicated circuit is not available, do not connect the control to a circuit that supplies high-
amperage equipment—use another circuit such as a lighting circuit. Otherwise, equipment may not
function properly.
WARNING! Electrical installation should be accomplished only by experi-
enced service personnel! OTHERWISE, DEATH, PERSONAL INJURY, OR
EQUIPMENT DAMAGE COULD OCCUR.

Storage Instructions
•Protect the adhesive from freezing.
•Store adhesives away from outside walls.
•Store adhesive at room temperature for three to four days before use.
Notes
•Fast-setting formulas will dry on nozzles more quickly. Therefore, it is necessary to wipe nozzles clean
before starting the system—even after very short periods of downtime.
•Always use a good machineable grade of adhesive. You will have fewer problems if the adhesive does
not shear. Shearing adhesive can be responsible for clogged glue valves, clogged applicator heads, and
clogged nozzles.
•Never use latex or starch adhesives.
•Never use adhesives with extenders (fillers).
•Do not mix resin-based and dextrin-based adhesives. Always check adhesive compatibility before
mixing.

Mechanical Installation of the Control
The control should be installed on the operator’s side of the parent machine, in a location where there are a mini-
mum of vibrations. The control should require less than 25 feet (8 m) of wiring to reach the glue station, sensor,and
shaft encoder (longer wiring is available on request). A 5/16" (8 mm) hex wrench (included with control) can be
used to unlock the door of the control enclosure.
To install the control, follow these steps:
1. Install the wall-mounting rail to the machine wall. (Ensure that the rail is level.)
Note! The center distance between the rail’s two mounting holes is 9.5" (241.3 mm).
Note! If the wall can be tapped, use a .203-diameter pilot drill and 1/4-20 tap. If wall is too thin, use a 0.281
diameter clearance drill and the supplied lockwashers and nuts.
2. Install the 1/4-20 x 1.5" socket-head capscrew into the wall mounting rail. (See Figure 6 for orientation of
rail.) Do not thread screw completely into rail.
3. Using 1/4-20 x 1/2" socket-head capscrews, install the cabinet-mounting rail to the upper set of mounting
holes in the rear of the cabinet. (See Figure 6-3 for orientation of rail.)
4. Ensure that the slot in the rail is facing away from the cabinet.
5. Using 1/4-20 x 1/2" socket-head capscrews, install the two mounting spacers to the lower set of holes in
rear of cabinet.
CAUTION! Do not use screws longer than 1/2" to mount the cabinet-mount-
ing rail and the mounting spacers to the rear of the cabinet. USING LONGER
SCREWS WILL DAMAGE THE CABINET.
6. Slide the cabinet rail over the wall rail so that both mounting rails interlock.
7. Tighten the 1/4-20 x 1.5" sockethead capscrew to scure the two rails together.
Note! The lower mounting spacers can be positioned vertically to provide additional mounting capabilities.
Securing the bottom of the cabinet to the wall will reduce cabinet vibration.
