4.0 PRESS LAYOUT
Figures 1 - 3 show the basic layout of the X-Press. The front view (Figure 1) shows the
location of the touch screen and START and STOP buttons, which are used to operate the
press. A loaded sample die is placed in the sample compartment on top of the platen and
secured in place by the adjustment screw, using the hand-wheel. A solid aluminum test
cylinder is provided as a "dummy" sample for testing. The manual pressure relief valve on
the right side of the press is used to release the hydraulic system pressure in an emergency
or for system maintenance; it is closed during normal press operations. This view also
shows the side access panel, which can be removed to fill the oil reservoir or check the oil
level.
In Figure 2 the side access panel has been removed, exposing the oil fill plug and port. This
view also shows the rear of the press and the locations of the power switch, power cord

6.0 DISPLAY SCREEN AND CONTROLS
The touch screen on front of the XP-400 X-Press is used to program the press. Upon start-
up, the Cole-Parmer and XP-400 X-Press logos will appear on the display screen, and the
START and STOP buttons will flash. After a few seconds, INITIALIZING…will briefly be
displayed at the bottom of the screen, indicating that initialization is in progress. When
STANDBY is displayed at the bottom, the press is ready for operation, as shown in Figure 4.
NOTE: The bottom of the screen will display the current mode of the program.
Figure 4 –X-Press Control Panel
The display screen shows the following buttons:
PRESSURE displays the piston force, from 0 to 35 tons, with a resolution of one ton. During
a run, the pressure will increase from zero to the set tonnage and will gradually fall to zero
as pressure is released at the end of a run. A minimum pressure of 10 tons is
recommended.
DWELL shows the time for which the maximum pressure will be maintained at the top of the
cycle and is adjustable in increments of 15 seconds. During a run, “DWELL” will be displayed
at bottom of the screen and the dwell time will count down in 1 second increments. The
minimum dwell time is 0 and the maximum is 10 minutes.
RELEASE indicates the time during which the system pressure will be bled to zero during an
automatic cycle. The word “RELEASE” will be displayed at bottom of the screen and will
count down in 1 second increments during a run. Release is adjustable in 15 second
increments. The minimum release time is 15 seconds and the maximum is 10 minutes.
The plus (+) and minus (-) buttons are used to increase or decrease the settings shown in
the PRESSURE, DWELL, and RELEASE fields. First press the button (e.g. Pressure) to activate
field then use plus (+) and minus (-) buttons to enter desired settings. (Figure 4)
STANDBY indicates that the press is in automatic mode. To operate in manual mode, touch

The current program step is displayed at the bottom of the screen during operation in
automatic mode. In manual mode, “MANUAL DWELL” and “MANUAL RELEASE” is displayed
at bottom of screen.
PUMP DOWN appears at the bottom on screen (at the end of a cycle) in automatic mode
while the platen is pumped down.
START and STOP buttons are located below the touch screen. Pressing the green START
button will start the operation of the X-Press. The pressure will be automatically released at
the end of a run. However, a run can be interrupted by pressing the red STOP button. This
will stop the operation, release the pressure, and reset the timer. During a run the green
START button will flash continuously. At the end of a run, the unit will “beep”, both the
START and STOP buttons will flash. If an error occurs, the STOP button will flash and the
“error message” will display at the bottom of the screen.
7.0 OPERATION
Before operating the XP-400 X-Press, make sure it is plugged in and switched on. The power
cord inlet is located at the rear of the press on the lower left. The off/on switch is a
standard rocker switch with the symbols 0 (for OFF) and | (for ON) and is located at the rear
of the press on the lower right.
If the unit does not activate, check to see that it is properly plugged in. If it is, check the
fuses at the rear of the unit (see Section 8.6).
Upon start-up, the main control screen is displayed. When the message changes to
STANDBY, the press is ready for operation.

1300-87043-1M, REV 3 Cole-Parmer® Page 13 of 26
7.1 Performing a Test Run
The XP-400 X-Press can be tested using the default settings as soon as the setup procedure
(Section 5.0) has been performed.
The factory-programmed setting stored in memory will come up on the display screen:
PRESSURE: 20 Tons
DWELL: 0:30 Min
RELEASE: 0:30 Min
Pressure is given in tons and the dwell and release times are shown in minute:second
format. For example, 0:30 represents thirty seconds.
Raise the sample chamber door and give it a slight push for it to hold in the open position.
Place the test cylinder in the press between the platen and the screw and center it on the
platen. Turn the hand-wheel until the adjustment screw makes contact with the top of the
cylinder, then back it off about 1/8" for this test. Close the door. Since the door actuates a
safety interlock, it must be closed during press operation.
Press the green START button. The unit will run through the automatic cycle:
1. The unit's main valve will close and the pump will pressurize the piston underneath
the platen. The platen will rise until the top of the test cylinder contacts the screw.
The word “STANDBY”will change to next step in program (e.g. Dwell).
2. The PRESSURE field will show the increasing force being exerted on the piston. The
unit will stop pumping when the pressure reaches the programmed setting of 20
tons.
3. The unit will pause for 30 seconds while the tonnage is held constant and DWELL is
displayed, dwell time counts down the remaining time.

7.1 Performing a Test Run (Cont’d)
4. At the end of the dwell period, the main valve will open and the PRESSURE display
will show the decreasing tonnage on the test block. The word RELEASE will be
displayed at the bottom of the screen and the time remaining in the release field,
counting down from 30 seconds.
5. When the release period ends and the applied tonnage is zero, the platen will pump
down, and PUMP DOWN will be displayed at bottom of screen.
6. The controls will reset to the beginning of a new cycle and the message at bottom of
screen will return to “STANDBY”.
7. The door can be opened at this point, or another cycle can be run by pressing the
START button again.
7.2 Changing the Settings
The X-Press always starts up in automatic mode, indicated by “STANDBY” displayed at the
bottom of the screen. One set of values is stored for the automatic cycle indefinitely, even
after the power to the press is turned off. The press will use these default values to run
automatic cycles unless programmed otherwise.
To change the PRESSURE, DWELL, or RELEASE settings, touch the appropriate button on the
display screen. Use the plus (+) and minus (-) buttons to adjust (to decrease and increase)
until the desired setting is reached. The new settings will be saved once the press is
operated at these settings. When the X-Press is turned off, it will revert to the last saved
settings upon start-up.
The X-Press is shipped with an initial set of default values: 20 tons pressure, 30 seconds
dwell, and 30 seconds release. These will remain the default values until the settings are
changed.
NOTE: For maximum consistency in pressure, it is not recommended that the X-Press be
operated below 10 tons.

7.3 Running an Automatic Cycle
Before running a cycle, be sure that the pellet die is properly loaded, that the plunger is
properly seated in the die, and that the die is centered on the platen. Turn the hand-wheel
to bring the adjustment screw in contact with the top of the plunger, and tighten to take up
any slack. Check to see that the STANDBY is displayed on the touch screen. If this field
displays “Manual”, the press is in manual mode. Touch AUTO/MANUAL button to revert to
automatic mode. Close the sample chamber door; the press will not run if the door is not
fully closed. A safety interlock engages once the START button has been pressed to lock the
door during operation.
Press the green START button to begin the run.
1. The main valve will close and the unit will pump up to the selected maximum
tonnage. The START button will flash continuously during the run and PUMPING will
be displayed followed by other functions (e.g. Dwell, etc.).
2. Once the set pressure is reached, the press will hold at maximum tonnage for the
specified dwell time, while the timer counts down in one-second increments.
3. At the end of the dwell period, the main valve will open and RELEASE is displayed as
the timer counts down to zero. The PRESSURE display will show the changing
tonnage as it gradually decreases. When the pressure reaches zero, the piston will
be brought back to its rest position. The message will change to “Pump Down”.
4. At the end of a run, or when the red STOP button is pressed, the unit will “beep “and
both the START and STOP buttons will flash. The controls will reset to the beginning
of a new cycle and the message at the bottom of the page will return to “STANDBY”.
5. The door can be opened and the die removed at this point.
NOTE: To halt the cycle at any point and return the tonnage to zero, press the red STOP
button.
The cycle may be run again immediately after the previous one is complete. Remember, the
door of the press must be closed during the cycle. If it is not, the safety interlock will
prevent the unit from running its cycle.
Figure 5 shows the operating cycle graphically. During the Pump Up Period, the press is
activated and the pressure increases from zero to the set tonnage. Then the pressure is
held constant during the Dwell Period. Finally, the pressure is relieved during the Release
Period and gradually decreases back to zero.

7.4 Manual Operation
Although the XP-400 X-Press is easy to program for automatic operation, the press can be
operated manually.
To run manually:
1. Insert a loaded die into the press, center it on the platen, and turn the hand-wheel
to bring the adjustment screw in contact with the top of the plunger. Tighten with
the hand-wheel to take up any slack. Close the sample chamber door.
2. Touch AUTO/MANUAL on the main screen. This field will change to display
“MANUAL”at bottom. All other fields will be inactive, prohibiting adjustment.
3. Press and hold the green START button. The pump will activate and the display
screen will show the increasing pressure in tons in the PRESSURE field. Release the
START button when the desired tonnage is reached.
4. The press will hold at the specified tonnage and the timer will count the elapsed
dwell time (maximum 30:00 minutes). Allow the press to hold for the desired length
of time. The START button will flash, indicating that the press is in operation.
5. Press the red STOP button to release. The unit will “beep” and main valve will open,
the pressure will gradually decrease to zero, and the timer will reset. The START and
STOP buttons will flash when the run is complete.
6. Touch the AUTO/MANUAL button to exit manual mode and return to automatic
mode. This releases the latch and allows the door to be opened.
7. Open the door and remove the sample die.

7.4 Manual Operation (Cont’d)
It is possible to increase the pressure during the dwell period. For instance, if after a
specified dwell time, a second dwell time at a higher pressure is desired:
1. Press and hold the START button to activate the pump.
2. Release the START button when the new target pressure is reached. The timer will
reset and begin counting the new dwell period.
3. When the desired dwell time has elapsed, press the STOP button to release the
pressure. The unit will “beep” signifying the run is complete.
NOTE: Touching AUTO/MANUAL button during a run in manual mode will immediately
release pressure and return the press to automatic mode.
7.5 Emergency Stops
During an automatic or manual run, the STOP button can be pressed at any time to
interrupt the cycle. The unit will “beep” signifying the run is complete and the X-Press will
immediately begin to pump the piston down and release pressure.
If the power is shut off during a run, pressure may remain. To relieve this pressure, open
the manual pressure-relief valve on the right side of the unit. Be sure to close it again
before continuing operation; this valve must be closed for the press to operate properly.

8.0 MAINTENANCE
8.1 General Procedures
The X-Press has been designed to provide trouble-free operation over a long period of time.
To assure proper performance, perhaps the most important factor is cleanliness. Any
spilled powders or hydraulic oil should be wiped up immediately. Although the X-Press is
designed for industrial use, it should not be exposed to dust, moisture, etc., more than
necessary, as those can affect both the mechanical and electronic functions.
Exposed steel parts, particularly the screw and platen, can be wiped down with rust
preventative oil. In doing this, care must be taken not to expose the electronics or cables to
oil, which can damage them. The motor bearings are factory-lubricated for ten years of use.
Before any hydraulic parts of the X-Press are disassembled, the manual pressure-relief valve
should be opened by turning the lever on the right side of the press counterclockwise. This
will bring all the oil in the press to safe pressure. The valve must be closed again for normal
press operations.
8.2 Removing the Cover
The sheet-metal enclosure at the rear of the X-Press is removable for such tasks as changing
or adjusting the V-belt or replacing the motor.
WARNING: Always unplug the X-Press before removing the cover to avoid hazardous
voltages!
To detach the rear cover it is necessary to remove the 8-32 x 3/8” button-head Allen screws
(two on each side, one on the back). On the left-hand side of the press there is a fill strip
that runs along the front edge of the cover. Remove the two screws on the front and the
side screw that sits midway up from the base (Figure 3). The rear cover and fill strip can
then be removed.

XP-400 X-Press
1300-87043-1M, REV 3 Cole-Parmer® Page 19 of 26
8.3 Draining, Refilling, and Checking Hydraulic Oil
It is recommended that the oil be changed annually using 20W hydraulic oil, Cole-Parmer
VPN 60361 (sold separately).
To drain the hydraulic oil for an oil change, there is a drain plug on the bottom of the oil
reservoir, reached through the base of the press. To access the drain plug, the plate on the
bottom of the press must be removed. Tilt the press to one side and support it while
removing the four #6 Phillips head screws from the edge of the base plate. Then tilt the
press to the other side and remove the remaining four screws. The base plate can then be
removed. Insert a shallow pan with a capacity of about one pint (500 ml) under the drain
plug. Remove the plug with a 5/32" Allen wrench. Return the press to its upright position;
the oil will drain into the catch pan.
To refill the X-Press, replace the drain plug and the base plate and fill the oil reservoir, first
remove the access panel on the right-hand side of the press (see Figure 1). Then remove
the fill plug from the fill port. Screw the pour spout onto the bottle of oil (sold separately)
and carefully pour into the fill port. (Pour slowly to avoid overflow.) Be sure to drain the
entire container into the press. Then replace the fill plug and the side plate. The oil capacity
of the press is about ¾ pint (355 ml). When the oil reservoir is filled, the oil level should be
approximately 1-1/8 inch (3 cm) above the bottom of the reservoir.
NOTE: Never use hydraulic fluid as this will cause serious damage to the press.
To measure the hydraulic oil level without removing the fill port, use a 6 inch rod of about
1/16 inch diameter. Take off the fill plug plastic cap and filter medium and measure the oil
level through the vent hole in the fill plug.
NOTE: Dirt is detrimental to any hydraulic device. Take suitable precautions to prevent
dust and debris from entering the fill port during filling and level-checking.

XP-400 X-Press
1300-87043-1M, REV 3 Cole-Parmer® Page 20 of 26
8.4 Bleeding the Air
The X-Press hydraulic system should be bled of air (a) whenever hydraulic oil is added, and
(b) after any repairs to the system.
Follow these simple steps to complete this operation.
1. Set the press to manual mode by touching AUTO/MANUAL on the main screen. This
field will change to display “MANUAL”.
2. Press and hold the green START button to operate the pump. Continue pumping
until the piston reaches its maximum height and the pressure reaches 5 tons.
3. Open the pressure relief valve on the side of the press.
4. Press and hold the green START button to move the piston back down to its lowest
position.
5. Let the press sit for 15 minutes to allow any air bubbles to escape.
6. Close the pressure relief valve.
8.5 Changing the V-Belt
The V-belt of the X-Press connects the motor with the hydraulic pump. If the pump cannot
attain maximum tonnage, it may be because the belt is slack and is slipping on its pulleys.
WARNING: Always unplug the X-Press before opening the cover, to avoid an electric shock
hazard. After changing the belt or motor, make sure that the motor mounting
bolts are tightened securely before operating the X-Press.
To tighten or replace the V-belt, the sheet metal cover must be removed as described in
Section 8.2. The V-belt may be tightened, or slacked off and removed, by loosening the
motor mounting bolts and shifting the motor. The motor mounting bolts are threaded into
the base of the X-Press.
V-belt tension may be checked by applying finger pressure to the V-belt halfway between
the motor and pump pulleys. If the V-belt can be depressed more than 3/8" (10 mm) it
should be tightened. A badly worn V-belt should be replaced.
The motor and pump pulleys must be properly aligned. Misalignment can cause excessive
operating noise, rapid wear of the V-belt, and damage to the motor or pump. When viewed
on edge, the pulleys should line up with respect to each other.
8.6 Changing the Fuses
Unplug the X-Press and open the door on the fuse compartment by lifting up. Press the
small tabs on the fuse holders out from the center and pull forward to remove the fuse
holders from the unit. Check the fuses using a continuity tester. If either fuse is blown or
defective, replace both with 3AG 10-amp, 250 V slow-blow fuses for the 115 V model. For
the 230 V model, use 3AG 5-amp, 250V slow-blow fuses. Replace the fuse holders and plug
the press back in to power outlet.
