Chapter 1: Introduction to the DES-42 C4 Pneumatic Heat Seal Machine
The DES-42 C4 is the most advanced heat sealing machine in the industry. In addition to being
dependable and easy to use, it offers the following features and capabilities:
Power “ON-OFF” Switch.
Intel Microprocessor based system controls and monitors all machine functions.
User friendly illuminated pushbutton inputs for setting of machine functions. Large red
LED display can be easily read up to 30 feet away and the readout has a rotating
sequence to display the time, temperature, and pressure settings.
Three conveniently located “Start Cycle” pushbuttons, one located on the front handle
and one located on each side of the machine. (To initiate cycle, the start button on the
handle must be depressed simultaneously with either one of the start buttons located
on the sides.)
Oversized “Emergency Release” pushbutton is located on each side of the machine. If
either one is actuated, press will immediately open.
Machine will cycle ONLY when top platen is in position directly over a bottom platen.
Top head swivels smoothly on two frictionless sealed bearings that are permanently
lubricated.
Dual Cycle Timer is programmable in ½ second increments. After the machine is
actuated, the timer counts down until the cycle is completed allowing the operator to
monitor the status of cycle at any time.
Built in resettable cycle counter displays cycle count up to 3999 and counts completed
and in-completed cycles independently on both cycle times. This discourages the
practice of operator short cycling, a major cause of tape adhesion failure.
Top and bottom platen temperatures are adjustable from 100° to 450° Fahrenheit. Top
or bottom platen temperature can be turned “OFF” individually if desired.
Air Regulator / Filter / Gauge Assembly attached to machine.
Air Pressure adjustable from 25 to 120 psi. Total platen pressure is approximately 707
lbs. at 100 psi line pressure.
The Air Cylinder has a ¾” diameter piston rod and the Guide Bar is made of ½” diameter
steel and glides through a DU bearing. Both assure long life, rigidity, and platen
alignment.
Control Lockout feature prevents unauthorized personnel from tampering with machine
settings.
Parameter Lockout feature prevents operator from cycling machine if temperature or
pressure varies more than +/- 10 from their set point.
Slide on Platen Covers for quick change from sponge pad or teflon surface.
Electrical Fuse mounted on circuit board inside machine.

Turning on Power to the DES-42 C4
Before turning on power, read the rest of this chapter carefully to learn how to make the
necessary adjustments and avoid potential problems. We recommend that you read this entire
manual to become familiar with its contents before operating the DES-42 C4.
To turn on the DES-42 C4, perform the following:
Push the toggle power switch up to the “ON” position.
Wait about two seconds for the DES-42 C4 to adjust. After the unit’s circuits settle, the control
panel displays the version of central processing unit (CPU) software and enters Monitoring mode.
For a complete explanation of Monitoring mode and the controls, see Chapter 4, Using the DES-42
C4 Control Panel.
Caution: If you press the Control Lockout button while the control panel is in Monitoring mode, it
will enter Set Lockout mode. In Set Lockout mode, you can select a three-button
sequence as a code to prevent unauthorized personnel from changing the parameters.
Immediately press Control Lockout again to exit this mode. See Chapter 11, Setting a
Control Lockout Code, for more information.

Chapter 3: General Operating Principles
Before you start using the DES-42 C4 pneumatic heat seal machine, read this chapter to become
familiar with general principles of all heat sealing operations and to learn the following operating
procedures that are specific to the DES-42 C4.
Actuating the DES-42 C4
Using the Emergency Release pushbutton
General Heat Sealing Principles
All heat sealing processes involve three main factors, as follows:
The temperature of the platens;
The inter-platen pressure;
The cycle dwell time.
To set tolerances and control values for platen temperature, inter-platen pressure, and cycle dwell
time, use the DES-42 C4 control panel. For more information, see Chapter 4, Using the DES-42 C4
Control Panel. You can also use the control panel’s digital display area to monitor the actual
platen temperatures and air line pressure. The exact settings of the three main factors depend on
the requirements of your specific fusing or transfer application.
Actuating the Heat Seal Machine
To actuate the DES-42 C4:
Position top platen over one of the bottom platens and depress the black pushbutton
labeled “Start Cycle” located on the handle simultaneously with one of the black
pushbuttons labeled “Start Cycle” located on either side of the swivel head. Machine will
cycle ONLY when the top platen is in position directly over a bottom platen.
Using the Emergency Release Pushbutton
To interrupt the DES-42 C4 during operation:
Push one of the red “Emergency Release” pushbuttons located on either side of the swivel
head. This safety feature bypasses the timer and immediately opens the press in case of an
emergency. Only one red pushbutton need be depressed to interrupt cycle. Also, the
press should open immediately if the power switch is turned “OFF”, or if the machine
power cord is unplugged.

Chapter 4: Using the DES-42 C4 Control Panel
This section of this manual provides an overview of the control panel for the DES-42 C4 pneumatic
heat seal machine. Before you operate your machine, read this section to learn general
information on using the control panel.
With the control panel, you can set tolerances and control values for platen temperature, inter-
platen pressure, and cycle dwell time. You can also use the control panel’s digital display area to
monitor the DES-42’s actual platen temperatures and air line pressure. The exact settings of the
three main factors depend on the requirements of your specific fusing or transfer application.
Use the Top Temp, Bottom Left Temp and Bottom Right Temp buttons on the control panel to
view and set the platens’ temperatures. Use the Air Line PSI button to view the actual pressure of
the heat seal machine’s pressure regulator and to set a control range. Use the Cycle Time button
in conjunction with either Cycle Time A or Cycle Time B button to set the actuation time and to
view the current time setting.
Layout of the Control Panel

Start-up and Monitoring Mode
When you first turn on the DES-42 C4, wait about two seconds for it to adjust. After the circuits
settle, the control panel displays the version of CPU software and enters Monitoring mode. In
Monitoring mode, the panel’s numeric display area shows the following values:
The cycle dwell time setting for cycle time A
The current top platen temperature in degrees Fahrenheit
The current bottom left platen temperature in degrees Fahrenheit
The current bottom right platen temperature in degrees Fahrenheit
The current air line pressure
The DES-42’s control panel enters Monitoring mode on initial start-up and when the machine is
idle. While in Monitoring mode, the control panel displays the current cycle dwell time setting for
cycle time A, current top platen temperature, current bottom left platen temperature, current
bottom right platen temperature, and current air line pressure, as shown in Figure 4-2. Because
the control panel displays the platens’ actual temperatures, it shows room temperature for them
when they are not on. If the machine’s pressure regulator is off, the control panel displays zero (0)
for air line pressure.
While the control panel is in Monitoring mode, you can immediately see any function displayed by
pressing and releasing either the Cycle Time A, Cycle Time B, Top Temp, Bottom Left Temp,
Bottom Right Temp, Air Line PSI, or Cycle Count button.
Caution: If you press the Control Lockout button while the control panel is in Monitoring mode, it
will enter Set Lockout mode. In Set Lockout mode, you can select a three-button
sequence as a code that prevents unauthorized personnel from changing the
parameters. Press Control Lockout again to exit this mode. See Chapter 11, Setting a
Control Lockout Sequence, for more information.

Chapter 9: Setting Air Line Pressure (PSI) Lockout Range
You cannot use the control panel to set the heat press device’s actual air line pressure (see
Chapter 2: Setting or Adjusting the Air Line Pressure). You must adjust the pressure regulator to
the desired setting. However, you can use the control panel to set a range limit that prevents
the heat seal machine from actuating unless the actual air line pressure is at the set value
(within the tolerance range of either +/- 10 psi). This is preset at Texas Automation Products
during manufacturing. To set the air line pressure lockout value, perform the following:
While the control panel is in Monitoring Mode, press and hold the Air Line PSI button.
After approximately two seconds, the panel’s Up Arrow and Down Arrow buttons will
light and the Air Line PSI button blinks, as shown in Figure 9-1. This puts the control
panel in the Set Mode. Release the Air Line PSI button. The control panel displays the
current pressure lockout setting.
Figure 9-1

Chapter 10: Cycle Count
The control panel’s cycle count feature allows you to accurately track the number of times the
DES-42 C4 has been actuated for the full-cycle dwell time and “short” cycle time on both the cycle
A time and the cycle B time since the cycle count was last reset. Each time you actuate the heat
seal machine for a completed cycle time setting, the control panel adds one (1) to its current cycle
count. If the machine is actuated and it is “short” cycled, it will add one (1) to its current “short”
cycle count. The control panel’s display area can display numbers from 0 to 999, but it also uses
decimal points, as shown in Table 10-1, to indicate cycle count values of 0 to 3999.

1. Press and release the Cycle Time B button.
2. Press and release the Cycle Count button to view the current full cycle count.
3. To view the current short cycle count, press and hold the cycle count button. After
approximately 2 seconds the button will light. Press and release the
button to view the short cycles.
You cannot use the control panel to increase the cycle count value; the count only increases
when the heat seal machine is successfully actuated for the full duration of the cycle dwell
time. You can, however, lower the count by increments of one (to reflect uses that were not
successful for reasons other than insufficient time) or reset the count completely to zero (0); for
assistance, see the procedures in Resetting Cycle Count on the next page.
