Safety Introduction Read and follow these safety instructions. Task- and equipment-specific warnings, cautions and instructions are included in equipment documentation where appropriate. Make sure all equipment documentation, including these instructions, is accessible to persons operating or servicing equipment. Qualified Personnel Equipment owners are responsible for making sure that EFD equipment is installed, operated and serviced by qualified personnel.
Safety High-Pressure Fluids High-pressure fluids, unless they are safely contained, are extremely hazardous. Always relieve fluid pressure before adjusting or servicing high pressure equipment. A jet of high-pressure fluid can cut like a knife and cause serious bodily injury, amputation, or death. Fluids penetrating the skin can also cause toxic poisoning. If you suffer a fluid injection injury, seek medical care immediately.
Getting Started The Ultra 2800 Dispensing System is designed to provide complete process control using a patented positive displacement technology. There are four core variables to the system: Deposit Volume, Dispense Rate, Pause and Pullback. To achieve the ideal deposit size, adjust only one of these variables at a time, in small increments.
Specifications Cabinet size: 18.4 W x 8.1 H x 32.3 D cm (7.25 x 3.18 x 12.73") Weight: 3.7 kg (8.2 lbs) Flexible cable assembly length: 1.8 m (6 ft) to end of handset Flexible cable assembly weight: .113 kg (4 oz) Flexible cable assembly bend radius: 7.62 cm (3.0") Internal power supply: Input voltage range, 100-240 VAC 18.4 cm 7.25" Max inrush current: 50A/264 VAC Input frequency range: 47-63 Hz 8.1 cm 3.18" Output voltage: 24 VDC Output current: 2.5A Output power: 60W Fuse rating: 1.
Dispenser Operation The Ultra 2800 Dispensing System uses a flexible hydraulic link to transfer linear force from the drive motor to the syringe barrel. The motor lead screw and drive shaft are also linked mechanically. This patented link allows the transfer of up to 200 pounds of force from the motor to the assembly fluid. Once a dispense cycle is complete, a programmed mechanical pullback retracts the plunger, attached to the EFD piston.
Features & Controls Program number Reset Deposit volume/ Forward Increase Barrel select F1 F2 F3 F4 Pullback/Back Pause Decrease Home Manual/Program select Cycle start Jog Reset shot count Dispense rate & Shot count/Volume Manual dispense rate Manual/Programmed Dispense Select • Each mode allows you to access different features on the menu-driven display. Press the “hand” icon to change from Manual mode to PROGRAMMED DISPENSE mode.
Features & Controls Barrel Select In both PROGRAMMED DISPENSE and MANUAL mode, pressing the top Single Barrel Select button activates the screen for the barrel size menu and pre-set dispense rates. • Press the F1 button to set barrel size. Use the (+) or (-) buttons to scroll through the various size options. • Press the F3 button to set Dispense Rate. Select Low, Medium, or High. The dual barrel select button is not active.
Features & Controls Shot Count/Deposit Volume (F3) In PROGRAMMED DISPENSE mode, pressing the F3 button lets you toggle between Shot Count and Deposit Volume. • Shot Count displays and tracks the number of deposit cycles. You can reset the Shot Count display to 0 by pressing the F4 button. • Deposit Volume displays the current volume programmed in cc’s. In MANUAL mode, the F3 button is not active. Other F3 commands: • From the Retract to Home screen, F3 allows you to select the Yes option.
Features & Controls Pause The Pause function “pauses” the action of the plunger during a dispense cycle, acts as a settling period and allows the relief of back pressure between Forward and Pullback steps. Pause is helpful when you are dispensing a large amount of material with a very small tip. In most cases you will not need to use the Pause function. In PROGRAMMED DISPENSE mode, press the Pause button to insert an end-of-cycle pause. Use the (+) or (-) buttons to set the Pause time.
Features & Controls Dispense Rate In both PROGRAMMED DISPENSE and MANUAL mode, pressing the Turtle button allows you to manually set the Dispense Rate. Use the (+) or (-) buttons to change the speed manually if needed. In most cases, however, we recommend that you simply use one of the preset Dispense Rates. • Press the Single Barrel Select button. • Press F3 to access the Dispense Rate options. • Select Low, Medium or High. Dispense Rate is based on cc’s per second.
Attaching the Syringe Barrel Flexible cable assembly without the syringe barrel Plunger Piston Adapter 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. 1. Unscrew and remove the barrel retainer from the adapter. 2. Put a tip cap on the syringe barrel and hold barrel next to the flexible cable assembly. 3.
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. The programs store the following information. • Syringe barrel size • Deposit volume • Dispense rate • Pause • Pullback Follow these steps to define a program 1. Select PROGRAMMED DISPENSE mode. (Press “hand” icon so red light is off.) 2. Press prg to highlight the program number.
How to Make a Bead Forward 1 10cc Shot Steps 0.0001cc 1 Hand icon To deposit a continuous bead of fluid, instead of a single dot, follow these steps. 1. Select PROGRAMMED DISPENSE mode. (Press “hand” icon so red light is off.) 2. Press Forward and use (+) or (-) buttons to set Dispense Volume to lowest setting. 3. As a beginning point, keep Pause set to 0 ms and Pullback at 200 steps, then adjust as needed to eliminate drooling. 4.
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. In most cases, you will want to use these pre-set specifications. However, you have the option to adjust the settings with the Modify function. Follow these steps to use the Modify function 1. From either the PROGRAMMED DISPENSE mode or the MANUAL mode, press the Single Barrel Select button.
Operating Tips Helpful Hints • Faster dispense rates require more Pullback steps. That’s because you are putting more pressure on the fluid, creating compression inside the syringe. For best results, use the preset default dispense rate of Medium. • If you are making small deposits, you are likely creating a lot of pressure trying to force the fluid through a small dispense tip. Begin with the largest tip practical to your application, with a slow dispense rate.
Pre-Load Adjustment The pre-load on the cable within the flexible cable assembly is preset at the factory. However, over time the cable may stretch slightly causing a change in performance. The pre-load adjustment block allows the user to make corrections to the pre-load due to cable stretch. If this happens, turn the pre-load plug clockwise to readjust the hex shaft to the 1/8" (3.2 mm) to 3/8" (9.5 mm) pre-load setting range. Do not exceed the 3/8" (9.
Syringe Barrel Filling Avoid air in the syringe barrel Air in the fluid is a critical issue with the Ultra 2800 Dispensing System. It can create problems with inconsistent deposits and drooling. For best results, use an EFD barrel filling station (see below), or bottom fill the syringe barrel. Simply insert the red piston and push it all the way inside the barrel, flush to the dispense tip. Then fill through the tip, pushing the piston down as the fluid enters.
Input/Output Connection Voltage Initiate Circuit The Ultra 2800 workstation may be initiated with a 5 to 24 VDC signal across pins 1 and 2. These two input pins are current driven and optically isolated. From Programmed Dispense mode, this signal can be momentary (no less than 0.01 seconds) or maintained. In this mode, a new dispense cycle begins once the 5 to 24 VDC signal is removed and then applied again.
Troubleshoot If you encounter a problem that you cannot readily solve, call EFD. Trouble Possible cause and correction No power Check the fuses and replace as needed. Follow these steps: 1. Disconnect the power to the unit prior to performing this service. 2. Locate the power entry module on the lower left corner of the rear panel. 3. If the electrical cord is still connected to the back of the unit, remove it now. 4.
