This User's Guide will help you maximize the usefulness of your new dispensing system. Please spend a few minutes to become familiar with the controls and features. Review the helpful information we have included, which is based on more than 30 years of industrial dispensing experience. [. . . ] Slower dispense rates give you better repeatability, since they create less fluid compression. This helps prevent oozing. Increase and Decrease In both PROGRAMMED DISPENSE and MANUAL mode, press the (+) or (-) button to change a number of variables, including Program Number, Deposit Volume, Dispense Rate, Pause milliseconds, Pullback steps and more. When the (+) or (-) buttons are pressed briefly, the settings will adjust slowly. When the (+) or (-) buttons are pressed and held, the settings will adjust faster. Back Panel Connect foot pedal Power Input On/Off Connect I/O 13 Attaching the Syringe Barrel Flexible cable assembly without the syringe barrel Plunger Adapter Piston Barrel retainer Flexible cable assembly with the syringe barrel Plunger Adapter Attach Barrel/Purge Tip Note: Stay in MANUAL mode for all steps to attach the barrel. Put a tip cap on the syringe barrel and hold barrel next to the flexible cable assembly. From MANUAL mode (hand icon light on), advance the plunger by pressing the Forward button, just until the plunger reaches past the piston. By hand, insert the plunger into the barrel, pressing it snugly into the piston. Press the Pullback button to retract barrel, until there is just a small gap between barrel and adapter. Slide barrel retainer over the barrel and thread one turn onto the adapter. Be sure not to overfill the tip since this results in excess back pressure, which can cause oozing. Caution: When the plunger fits into the piston, stop pressing Forward. If you continue, excess pressure can build inside the barrel and may cause it to burst, resulting in serious injury. Note: See the handout provided with your Ultra 2800 dispenser, Syringe Barrel Attachment Guide, for simple, step-by-step instructions. Removing the syringe barrel 1. Discard the barrel, or if storing for later use, replace the dispense tip with a tip cap. Screw the barrel retainer back onto the adapter. 14 Program Function Program number Forward Barrel select 1 30cc Shot Steps 0. 0500cc 160 Back Pause Hand icon The Ultra 2800 Dispensing System offers 100 user-defined memory programs, ranging from 0-99. · · · · · Syringe barrel size Deposit volume Dispense rate Pause Pullback Follow these steps to define a program 1.

Press Forward and use (+) or (-) buttons to set Dispense Volume to lowest setting. As a beginning point, keep Pause set to 0 ms and Pullback at 200 steps, then adjust as needed to eliminate drooling. For best results, set Dispense Rate to the preset of Lo, to minimize back pressure in the syringe barrel. (Note: the Cycle Start button is not active in Manual mode, so use the foot pedal to activate the dispense cycle. ) 16 Modify Function Modify Function Barrel select 1 30cc 2. 265 Dia 7. 60 Strk F1/Button The Ultra Dispensing System includes pre-set specifications based on industry-standard EFD syringe barrel dimensions.

[. . . ] To check, unscrew the retainer from the adapter and turn the syringe barrel upside down. See the handout, "Syringe Barrel Attachment Guide, " for step-by-step instructions on how to properly engage the plunger and piston. Oozing Inconsistent shot size 1. There is air in the syringe barrel, either entering the barrel during filling, or from excessive Pullback. The Dispense Rate may be too fast for the combination of fluid viscosity and dispense tip.
