Getting Started
The 2000XL Series automatic fluid dispensers are designed to
provide complete process control using advanced microprocessor
circuitry. All microprocessor functions are accessed by push button.
Microprocessor features include:
• Push-button time setting input or one-touch time programming.
• Floating decimal, providing dispense time ranges of 0.001 to 9.999
and 00.01 to 99.99 seconds.
• Backlit LCD displays time settings, dispensing pressure and
vacuum pressure.
• Dispensing pressure display is programmable for either psi or bar
scale.
• Memory with storage for up to eight separate time settings.
Intelligent technology makes the 2000XL Series easy to set up and
use. With one-touch setup, just press the pedal to determine the
proper amount. The microprocessor remembers the time and
repeats this amount with each cycle until you are ready to change it.
From microdeposits to volumetric filling, the 2000XL provides the
ultimate in control and versatility for time/pressure-based fluid
dispensing.

First Steps
First: Unpack and use the checklist enclosed with the Dispenser Kit
to identify all items. If there is any discrepancy, please call us
immediately.
Second: Power and compressed plant air should be available where
the dispenser is to be set up. Input air should be set between 80 and
100 psi (5.5 and 6.9 bar). For model 2000XL-PR5, input air should
be set between 10 and 50 psi (0.7 and 3.4 bar). If you are not using
an EFD five-micron filter regulator #2000F755, be certain your
plant air is properly filtered and dry and a regulated, constant
air pressure is supplied to the dispenser.
Note: Model 2000XL-CA is supplied with an EFD five-micron filter
regulator with coalescing filter (#2000F756).
Bottled nitrogen can be used.
Warning: If high pressure bottled air or nitrogen is used, a high
pressure regulator must be installed on the bottle and set at 100 psi
maximum. The 2000F755 filter regulator is not required.
Check the voltage label to be certain it is set to the available power.
Third: Now is a good time to ACTIVATE your extended Ten Year
No-fault Warranty. Please fill in and return the postage paid
Warranty card. Or if you prefer, call the appropriate toll-free number
listed below, provide the serial number of your dispenser and
respond to a few short questions.

The dispenser should be in the RUN mode, the
TIME setting should be 2.30 seconds and the
dispensing pressure should be 20 psi (1.4 bar).
Increasing the pressure will result in larger depos-
its, decreasing the pressure will result in smaller
deposits. Try this now and observe the results.
Tip Size—changes deposit size.
Tip size also affects deposit size. Without changing the TIME or PRESSURE setting, try different tips
and observe the results.
Don’t Forget!
✓ Changes to the time settings can be
made only when the mode of operation
is SETUP.
✓ RUN mode locks out TIME SET and TEACH
control buttons. Use this to protect the
setup from inadvertent changes.
✓ Pressing STEADY/TEACH in SETUP mode
will clear all time settings within cell.
✓ STOP immediately terminates the current
dispense cycle.
✓ Use only dry, clean, filtered air.

Advanced Dispensing System
TM
If you dispense thick fluids, several problems may
occur. First, the repetitive air cycles can bore
tunnels through non-leveling fluids, causing
spitting and inconsistent deposits. Second, thick
fluids contain trapped air that leads to drooling
and oozing.
These problems are eliminated by using the
SmoothFlow™ piston. That's because the white
pistons prevent tunneling by providing a barrier to
the pulsed-air cycles, and prevent oozing by
responding to the pressure of trapped air with a
slight suck-back movement after the dispense
cycle.
The white piston is used for most fluids.
However, if you are applying RTV silicone and
find that the piston bounces and causes stringing,
switch to the orange, flat wall piston.
The SmoothFlow™ pistons make barrel filling
easier, too. As you load the fluid in, air is trapped
in the bottom and throughout the fluid. Simply
insert a SmoothFlow™ piston and gently press
down on the fluid as far as possible. This action
forces out most of the air and results in consistent
deposits.
For Thick Fluids

No drip
or ooze.
If you use low to medium viscosity fluids, the white
SmoothFlow™ piston has several advantages.
First, vacuum adjustment is much less sensitive.
Second, the piston prevents fumes from the fluid
being exhausted into the work environment. Third,
the piston prevents fluid backflow into the dispenser if the barrel is inadvertently turned upside
down. Fourth, using the piston makes it easy and
safe to change tips without dripping.
Note: If you use watery-thin fluids such as solvents,
cyanoacrylates and anaerobics, specify the ULTRA
System™ with the blue LV Barrier™. Available in
3cc and 10cc sizes.
For Cyanoacrylates
or Watery-thin Fluids

No air gap when using the
SmoothFlow™ piston.
Note: If you choose not to use the piston,
please refer to page 17 for instructions.
How to use the Vacuum Control
The vacuum control allows low viscosity fluids, even water, to be
consistently dispensed without dripping between cycles. The vacuum
exerts a negative pressure on the liquid in the barrel and prevents
dripping.
For these tests, you will use the test barrel with the clear fluid.
Remove
orange
end cap.
1. While holding the barrel upright in one hand, remove the orange
end cap and insert the blue LV Barrier™. Allow an air gap as
shown.
2. Attach the barrel to the 10cc adapter. Snap the safety clip tightly
closed to prevent any dripping or bubbling. Remove the tip cap
and attach the 30 gage (lavender) tip.
3. Set air pressure at 5 psi.
4. Press RUN/SETUP to go into SETUP mode and set TIME for 00.05
seconds. Press RUN/SETUP to return to RUN mode.
5. Press STEADY/TEACH (STEADY indicator light on).
6. With the barrel pointing downward over a container, unsnap the
safety clip and press the foot pedal to fill the tip.
7. If a drop begins to form at the end of the tip, slowly turn the
vacuum control knob counterclockwise to stop the drop from
growing. Wipe the tip and adjust vacuum as necessary.
8. To read vacuum pressure, press PRESSURE/TIME so that system
air pressure is displayed. Hold toggle switch in the "up" position
to view vacuum pressure. Release toggle to return display to
system air pressure readout.
9. Press STEADY/TEACH (STEADY indicator light off).
Insert
blue LV
Barrier
Remove
tip cap.
™
10. Take the barrel and place the tip on the test sheet. Press the foot
pedal and release. Check the dot size. Increase or decrease by
adjusting pressure or time.
Three things to remember
If you do not use the piston when
dispensing thin fluids:
Do not tip the barrel upside down
or lay flat. This will cause the
liquid to run into the dispenser.
Open
Closed
When changing tips
or attaching a tip cap,
snap the safety clip
completely closed to
prevent any dripping
or bubbling.
If you choose not
+to use the piston, please follow these instructions carefully:
1. While holding the barrel upright in one hand, twist on an orange
tip cap. Using the small funnel, fill about 2/3 full with your fluid.
2. Open the safety clip and attach the barrel to the 10cc adapter.
3. Close the safety clip as tight as possible.
4. Slightly increase vacuum by turning vacuum control knob
counterclockwise.
5. Then, without tipping the barrel upside down, remove the tip cap
and attach the 30 gage (lavender) tip.
6. Open the safety clip. Your material may begin to bubble. Reduce
vacuum by turning vacuum control knob clockwise.
7. If a drop begins to form at the end of the tip, slowly turn the vacuum
control knob counterclockwise to stop the drop from growing.
Wipe the tip and adjust vacuum as necessary.
Use an EFD filter trap
(#1000FLT-Y). This
filter trap will impede
the flow should the
low viscosity liquid be
sucked back towards
the dispenser.
Now the fluid is in proper balance. It does not bubble or drip.
Repeat tests as before, keeping the air pressure low and adjusting
the time for different deposit sizes.

Loading the Barrel Reservoirs
Caution: Do not completely fill barrels. The optimum fill is a maximum
2/3 of the barrel capacity and 1/2 of the barrel capacity when using
the LV Barrier™.
If the fluid you are dispensing is pourable, take the barrel, twist on a
tip cap and pour your fluid in. If appropriate, insert the SmoothFlow
piston (see page 14). Carefully press the piston down until it contacts
the fluid. The barrel is now ready for use.
If you are dispensing watery solvents, cyanoacrylates or anaerobics,
use the LV Barrier™. Place barrier in the top of the barrel reservoir.
Allow air between barrier and fluid. Do not contact the barrier to the
fluid.
If your fluid is thick or non-leveling, you can spoon it into the barrel with
a spatula. Or, if the fluid comes packed in a 1/10 gallon cartridge, try
loading the barrel with a caulking gun. Then, press in the SmoothFlow
piston to move the fluid to the bottom of the barrel and to remove
trapped air.

Filling the cartridge
for the barrel loader.
EFD offers productive alternatives to traditional barrel loading methods. Here are a few suggestions that can help keep your work area
clean, save time and reduce the chance of entrapped air in the fluid.
1. You could use the EFD #920BL barrel loader. Pack the fluid into
the 12 ounce cartridge as shown. Then place the prefilled
cartridge into the barrel loader. Using air pressure, the barrel
loader fills the barrel (with piston) from the bottom up.
If the fluid comes packed in a 1/10 gallon (300 ml.) caulking type
cartridge, use the EFD #940BL barrel loader.
2. If you receive frozen epoxies or other fluids in medical type
syringes with a manual plunger, request our luer-to-luer fitting
#2160 to transfer the material.
Please call an EFD Fluid Application Specialist
for additional assistance.

Voltage Initiate Circuit
The 2000XL may be initiated with a 5 to 24 VDC signal across pins
1 and 2. The signal can be momentary (no less than 0.001 seconds)
or maintained. A new cycle will begin once power is removed and
then applied again.
Mechanical Contact Initiate
The 2000XL can be initiated via the closure of mechanical contacts
such as a relay or switch using pins 5 and 7. Closure of the contacts
can be momentary (no less than 0.001 seconds) or maintained. A
new cycle will begin once the contacts are opened and then closed
again.
End-of-Cycle Feedback Circuit
Upon completion of a dispense cycle, an open collector circuit closes
and remains closed until the next dispense cycle. This circuit can be
utilized to signal back to a host computer, start another device in
sequence or other operations that need to be tied into the completion
of the dispense cycle.
Upon closure, power from an external 5 to 24 VDC source is allowed
to pass through the circuit to operate a load. Power consumption of
the load must not exceed 250mA.
I/O Connection
The 9 pin D connector and
internal circuitry provide
external initiate and endof-cycle feedback signal.

Troubleshooting
If you encounter a problem that you cannot readily solve, call EFD.
Trouble Possible cause and correction
No power. Be sure that there is power at the wall receptacle. Check the input
power fuse. If the fuse has failed, check the voltage value in the fuse
cartridge window. Be sure that it matches the input voltage.
Auxiliary output is not Insure that the external voltage to the circuit is between 5 and 24 VDC
functioning. and that the load does not exceed 250mA.
If the output has been overloaded, the fuse may be open. See schematic on page 23 and replace if necessary.
Inconsistent dots. 1. Check dispensing tip, barrel and material for possible clogging.
2. Check dispenser air pressure reading to be sure air pressure is
not varying.
3. Air bubbles in the material can cause inconsistency. For best
results, remove all air bubbles.
Timer seems inoperative. Check to be sure STEADY mode is off.
Note: The EFD timer is very reliable. Any failure will be total, so that
no inconsistency is possible. Most questions regarding the timer are
resolved by simply turning the STEADY mode off.
Material suck-back. 1. Use SmoothFlow™ pistons or LV Barriers™ to prevent this (see
pages 14 and 15).
2. If it occurs, attach an empty barrel, put in STEADY mode, place
the barrel in a cup then press the pedal to expel the fluid.
3. If problem cannot be corrected, contact an EFD Product Specialist
for assistance. Dispensers can be returned to EFD for repair.
Suggestions & Reminders
1. Always use an EFD piston to make your barrel loading, dispens-
ing and handling cleaner, safer and more accurate.
#DS1200
DispenStand
#7300A
Barrel Stand
Caution: If you dispense watery-thin fluids and choose not to use
™
SmoothFlow™ pistons – do not increase vacuum pressure rapidly
and do not tip the barrel. Vacuum may pull liquid into the air hose;
or when tipped, liquid may flow back into the dispenser.
2. Always use new barrels and tips. Carefully dispose of after use.
This procedure ensures maximum cleanliness, prevents contamination and provides proper safety.
3. Do not completely fill the barrel. For most fluids, optimum fill is
a maximum 2/3 of the barrel capacity. For cyanoacrylates or
watery-thin fluids, optimum fill is 1/2 of the barrel capacity.
4. Use the EFD #DS1200 DispenStand™ (supplied with model
2000XL-CA) to help organize bench space. Adapter hose
support keeps hose off of the work area. See illustration.
5. Depending on the type of work you are doing, it may be easier
to bring the work to the barrel. Mount the barrel on a stand such
as the EFD #7300A.
6. To ensure smooth fluid flow and to make consistent deposits,
always have the tip at about a 45° angle to the work surface.
