DESCRIPTION
Description
The ITW Dynatec DPC-2 Distance-based Pattern Control unit is a microprocessor-based
electronic control system. It may be used in any process that requires the actuation of
electrical output devices based upon distance traveled. It is specifically designed to
control glue application valves used in adhesive systems. Examples of applications where
the DPC-2 may be used include, but are not limited to, case sealing, labeling, and bag
making.
The DPC-2 can be operated on either 120v or 240v AC, single-phase power. A set of
contacts is provided to allow a signal to be sent to an external controller (such as a PLC)
when the DPC-2 is switched on.
All controls and displays are mounted inside a rugged enclosure with a protective door.
The enclosure meets environmental ratings of IP54, protecting against water and solid
object infiltration when the door is latched and all output/input receptacles at the bottom
of the DPC-2 Control Unit are either connected to cables or capped. The display is a
bright, seven-segment LED device that affords easy viewing at any angle and in any
lighting environment. All connectors are standardized to simplify installation.
The DPC-2 Control Unit has non-volatile memory for up to four programs. Each program
has two CHANNEL outputs. Each CHANNEL is independent of the other and has four
programmable EVENTS. An EVENT is defined as a DELAY (no glue) and a LINE
(glue). Each LINE may be programmed to apply continuous glue or apply in a STITCH
(series of dashes) or SPOT (series of dots) pattern.
Programming is accomplished by depressing the appropriate CHANNEL or SYSTEM
button until the desired parameter LED is illuminated on the left side of the display panel.
Depressing the DIGIT button causes the values on the display to flash. Rotating the
VALUE knob modifies the displayed value. Depressing the RUN/STOP button so the
LED is illuminated signifies the glue system is active and will respond to trigger inputs.
Activity of the DRIVE 1, DRIVE 2 and A.T.S. (Automatic Tip Sealer) outputs and the
TRIGGER input is indicated in the top right corner of the display via illumination of the
respective LED's.
Facilities for a remote PURGE device (supplied standard with the system) and Automatic
Tip Sealers (optional equipment used in cold glue systems) offer the operator ease of glue
system maintenance during times of system inactivity. The Automatic Tip Sealer (A.T.S.)
Drive output is provided for use with cold glue systems that may employ tip sealing
devices to prevent the glue from drying in the applicator nozzle during periods of glue
system inactivity.
Pattern initiation may be set for either of two trigger modes: Single or Repeat. See
Chapter 2 (Operation and Programming) for further information concerning TRIGGER
MODE.
