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.
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).

Setup for Testing Deposit size is controlled by TIME, PRESSURE and TIP SIZE. Attach the barrel containing the test material to the adapter assembly ❹ as shown. Please follow these instructions in order to test each function. Use the convenient Dot Test sheet included in your Test Kit. Remove the orange tip cap from the end of the dispensing barrel and attach the green 18 gage tapered tip ❺ found in the Dot Test Kit. Place the barrel in the barrel stand.
Testing (continued) Program (TEACH) the Deposit Time with the Foot Pedal When a specific time value is not known, as when first dispensing an amount, the time may be programmed using the foot pedal. Press RUN/SETUP to set the dispenser into RUN mode (RUN indicator light on). Select the memory cell you wish to program, e.g. CEL1, CEL2....CEL8. Return the dispenser to SETUP mode and clear cell memory by pressing STEADY/TEACH.
Note: The pedal needs only to be pressed momentarily. The complete time cycle will run once the dispenser is initiated. Don’t Forget! ✓ Changes to the time settings can be made only when the mode of operation is SETUP. Press RUN/SETUP and toggle back to the SETUP mode. Press the TIME SET buttons and change the time to 2.30 seconds. Go back to RUN, press the foot pedal, and the dispenser will make a deposit approximately twice the size of the first one.
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. For Thick Fluids Air Pressure ON Air Pressure OFF These problems are eliminated by using the SmoothFlow™ piston.
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.
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. 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. Remove orange end cap. Insert blue LV Barrier™ 2.
If you choose not Three things to remember If you do not use the piston when dispensing thin fluids: +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. Do not tip the barrel upside down or lay flat.
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.
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.
Memory The memory feature enables storage of up to eight different time settings that can be recalled and used at the push of a button. Time settings are saved even with power removed and will remain in storage unless changed or erased intentionally. Memory cells are identified as CEL1 through CEL8. Viewing MEMORY cells C E L 3 Before saving a time setting in memory, view the memory cells to see which cells are empty or, if all cells are used, which time can be replaced.
Saving a time in a MEMORY cell 1. Determine the cell in which a new time value is to be stored, e.g., CEL1, CEL2... (Refer to "Viewing MEMORY cells" on page 20). 2. Press RUN/SETUP to place the dispenser in SETUP mode (SETUP indicator light on). Note: Once cell value s are cleared, they canot be recalled. 3. Press STEADY/TEACH to clear cell contents. 4. Enter the desired time setting by using the TIME SET button or the TEACH function and foot pedal (refer to page 12). 5.
Input / Output Connection Instructions 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.

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 functioning. Insure that the external voltage to the circuit is between 5 and 24 VDC and that the load does not exceed 250mA.
Suggestions & Reminders 1. Always use an EFD piston to make your barrel loading, dispensing and handling cleaner, safer and more accurate. #DS1200 DispenStand™ 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.
