The 2000XL Series automatic fluid dispensers are designed to
provide complete process control using advanced microprocessor
circuitry. Allmicroprocessorfunctionsareaccessedbypushbutton.
Microprocessor features include:
• Push-button time setting input or one-touch time programming.
• Floatingdecimal,providingdispensetimerangesof0.001to9.999
and 00.01 to 99.99 seconds.
• Backlit LCD displays time settings, dispensing pressure and
vacuum pressure.
• Dispensingpressure 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
repeatsthis amount with eachcycleuntil you are readytochange it.
From microdeposits to volumetric filling, the 2000XL provides the
ultimate in control and versatility for time/pressure-based fluid
dispensing.

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

Advanced Dispensing System
Ifyoudispensethickfluids,severalproblemsmay
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
pistonspreventtunnelingbyprovidingabarrierto
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
findthatthepistonbouncesandcausesstringing,
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
forcesoutmostoftheairandresultsinconsistent
deposits.

Ifyouuselowtomediumviscosityfluids,thewhite
SmoothFlow™piston has several advantages.
First, vacuum adjustment is much less sensitive.
Second, the piston prevents fumes from the fluid
beingexhaustedintotheworkenvironment. Third,
the piston prevents fluid backflow into the dis-
penser if the barrel is inadvertently turned upside
down. Fourth,using the piston makesit easy and
safe to change tips without dripping.

The vacuum control allows low viscosity fluids, even water, to be
consistentlydispensedwithoutdrippingbetweencycles. Thevacuum
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.

If you choose not

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. Openthesafetyclip.Yourmaterialmaybegintobubble. Reduce

7. Ifadropbeginstoformattheendofthetip,slowlyturnthevacuum
control knob counterclockwise to stop the drop from growing.
Wipe the tip and adjust vacuum as necessary.
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.
Do not tip the barrel upside down
or lay flat. This will cause the
liquid to run into the dispenser.
When changing tips
or attaching a tip cap,
snap the safety clip
completely closed to
prevent any dripping
or bubbling.
Three things to remember
If you do not use the piston when
dispensing thin fluids:
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.
