This manual has been prepared by Valco Cincinnati, Inc. to provide
assistance in the set-up and operation of the MCP-6 Control Unit.
The MCP-6 Control Unit from Valco provides operators with a full-featured
affordable solution to adhesive system pattern control. The unit allows
program changes and adjustments, so you can get desired results
immediately.
The MCP-6 Control Unit works with Valco’s 24VDC adhesive dispensing
valves, and is CE Compliant .
System
Description
All hardware must be up-to-date for all
new functions to work. Please see the
Parts List for a compatibility chart.
Labeler Application
ControlDescription
The reason for providing variable time ranges is to extend the performance
life of both the glue valves and solenoid valves. When the time cycle is set
properly, all valves remain energized during continuous product flow. Upon
startup, or after a production interruption, the valves are energized and de-
energized per individual container, until product flow reaches the production
rate corresponding with the cycle-time setting.
The scanner provides a momentary signal to start the independent time
cycle, affording maximum scanner mount flexibility.
The scanner also performs an automatic jam detection function by seeking a
void between each product. If the scanner doesn’t see avoid, it won’t allow
another cycle to start.
The operator dictates the cycle time by setting the activation.

EPC12Application
Control Description
The EPC12 monitors pulses received from an optical encoder (the encoder is
driven by the parent machine).
Pulse speed is converted to voltage.
An air manifold is mounted within the EPC12 cabinet. Air pressure within the
manifold is monitored by a pressure transducer. EPC12 circuitry compares
transducer voltage with encoder-speed voltage. Air is supplied to the
manifold if the transducer voltage is lower than the encoder-speed voltage.
Air is exhausted from the manifold if the transducer voltage is higher than the
encoder-speed voltage. This way, manifold pressure is proportional to parent
machine speed.
On cold-glue systems, manifold air pressure enters the cap of a standard
non-relief fluid regulator through the vent port. The adjusting screw is set for
low speed or idle operation. Manifold air pressure from the EPC12 moves the
diaphragm away from the regulator spring in proportion to parent machine
speed.
On hot-melt systems, the EPC12 can control the air pressure to an air-driven
adhesive pump and pneumatic compound relief valves, to increase and
decrease adhesive pressure related to machine speed.
EPC12 Capabilities •Fluid-flow controlFluid-flow control
Fluid-flow controlFluid-flow control
Fluid-flow control - The EPC12 changes fluid-pressure
regulator output in response to parent machine speed changes.
The unit controls air-driven, cold-glue systems to obtain uniform
glue application regardless of parent machine speed. In adding
an external EPC, refer to the wiring diagram below for options.
•Glue-valve activationGlue-valve activation
Glue-valve activationGlue-valve activation
Glue-valve activation -The EPC12 can supply a signal to
operate a 24-volt, 3-way solenoid. The EPC can also send a
signal to another control, when more than one valve is being
activated (8.5 watts maximum). A minimum-speed adjustment
feature disables this valve output below a threshhold machine
speed.
•Web detection (optional)Web detection (optional)

Web detection (optional) - For continuous gluing
applications, an LED scanner can be added to monitor the web.
If the web breaks, the glue application will stop (scanner 4).
