1.1 Advanjet HV-2000 Jet Overview Advanjet HV-2000 non-contact jetting technology is a major leap in liquid dispensing. The jet valve features Advanjet’s patented diaphragm design: a single, easily replaceable diaphragm eliminates the many dynamic fluid seals common in all other jets. The inherent advantages of this design are significant: ■ The diaphragm’s very low mass allows very fast cycle rates since there is not a large sliding valve stem to slow down the process. ■ With the novel diaphragm design, the energy needed to eject a drop can be adjusted, providing wider process windows. As...

Shown below are the mechanical dimensions of the HV-2000.  The HV-2000 can be mounted to a variety of robots when X-Y-Z motion is desired. It can also be mounted rigidly over a transporting mechanism like a conveyor belt or shuttle table. The HV-2000 provides mounting holes located on the rear mounting plate for rigid attachment to a robot’s X-Y-Z stage. Additionally, the rear mounting plate allows the jet to be mounted in a channel which allows adjustment of the dispense tip to the dispensing surface. The dispense tip relative to the mounting holes and the rear mounting plate dimensions...

Dispensing Components As illustrated in Figure 2-1 below, the HV-2000 has three components in contact with the fluid: the nozzle plate, diaphragm, and the feed tube. The materials of these components are listed in the table below. These components can be easily disassembled with two screws, cleaned, and reused. Cleaning procedures are in Section 4 - Cleaning the Jet. The diaphragm should be inspected each time the nozzle plate is removed. If there are signs of wear, cracks, or deformation, the diaphragm should be replaced. FEED TUBE O-RING NOZZLE PLATE Figure 2-1: HV-2000 Jet Dispensing...

It is imperative that the air supplied to the HV-2000 Jet Valve is clean, dry and free from debris and water. A 40-micron filter, a water separator, and an overpressure relief valve set at around 120 psi (0.83 MPa) are highly recommended. If the air is not clean and dry, serious damage can occur to the solenoid valves. The air supply pressure should be between 70 and 100 psi (0.48 and 0.70 MPa). 4-mm OD TUBE [LOCKING BAYONET] 6-mm OD TUBE SLIP CONNECT COUPLER Figure 2-2: HV-2000 Pneumatic Connections (Shown with the HV-2000C Controller) Referring to Figure 2-2, connect an independently...

Electrical Interface – Controller Figure 2-3: HV-2000 Cable Connections (Shown With HV-2000C) Four cable connections are on the rear of the Advanjet controller: power cord, RS-232, jet, and digital I/O, as shown in Figure 2-3. To ensure proper connections to the Advanjet controller, each of the standard cables supplied by Advanjet has a distinct connector. NOTICE To prevent unintended dispensing, be sure that all power is off when connecting or disconnecting cables from the Advanjet controller. Power: The power cord set includes a standard 3-wire cable (hot, neutral, ground) with an IEC C13...

A 15-pin cable is supplied with the HV-2000 Jet Valve. The table below describes the Jet cable pin assignments. ■ Pins 2 and 7 are for the solenoid. ■ Pins 10 and 13 are for the heater. ■ Pins 11, 14, and 15 are for the RTD. Pins 11 and 15 are jumped internally in the cable. STANDARD HD-15 JET CABLE PIN ASSIGNMENTS 3A5855A Advanjet HV-2000 Jet Setup and Operation Page 11 of 24

The HV-2000 Jet Valve is shipped fully assembled except for a diaphragm and nozzle plate. A specific diaphragm material and nozzle plate orifice diameter should be chosen based on the application and dispensing fluid. Refer to the Jet Dispensing Parameters Supplement manual 3A5937. The steps required to correctly assemble the diaphragm and nozzle plate on the jet body are listed below. Figure 3-1 below shows the fit and alignment of the HV-2000 Jet Valve heater block, diaphragm, o-ring, and nozzle plate.  There is a grooved pattern on the bottom face of the heater block that matches the...

Electrical and Pneumatic Connections Before assembling the jet, make the necessary pneumatic and electrical connections to the jet controller as described in Sections 2.2 and 2.3. Inspect the Nozzle Plate for Cleanliness It is important to inspect the nozzle plate for debris before mounting it onto the Jet. If the nozzle plate is not clean, it could affect the dispensing quality. These dispensing problems are symptoms of a contaminated jet:  Unclean or uneven dispensing.  Drops become irregular or vary in size.  Residual flow or drooling out of the tip when the jet is in the closed...

When the nozzle becomes damaged or plugged, a new nozzle insert may be required. Installation is simple, but correct and careful assembly is important. 1. Disassemble the nozzle plate by removing the 3 screws from the nozzle plate bottom. 2. Flip over and remove the nozzle plate top and the nozzle insert. Save the o-ring. 3. Clean as needed. 4. Mount the nozzle insert o-ring. Note that the o-ring for the insert is smaller than the o-ring for the nozzle plate. 5. Set the nozzle insert tip down on the inside face of the nozzle plate bottom. Replace the nozzle plate top and insert and tighten...
