1. Introduction and Specifications
1.1 Advanjet HV-2000/2000C Overview
Advanjet HV-2000 non-contact jetting technology is a major leap in liquid dispensing.
The non-contact jetting is fast, allowing dispensing rates up to 300Hz. The user can
modify the drop size ± 20% from its nominal size, allowing a wide range of adjustability.
The simplicity of HV-2000 is also evident in its ease of cleaning, since all parts that
touch the fluid are easily removed.
The Advanjet HV-2000C controller provides timing signals as well as pneumatic and
electrical resources for the Advanjet HV-2000 Jet Valve.
The HV-2000C provides timing signals to drive a rapid-response solenoid valve
in the HV-2000 Jet Valve. Its internal computer remembers and executes a
variety of operational sequences. The controller can respond to actuation signals
from either a front panel switch or from an external switch.
The HV-2000C provides regulated, pressurized air for the fluid pressure and jet
pressure of the HV-2000 Jet Valve.
The HV-2000C provides electrical power to a heater element in the HV-2000 Jet
Valve, and controls the temperature of the valve’s heater by monitoring a
resistance temperature detector (RTD) sensor in the HV-2000 Jet Valve.

2. Installation and Setup
2.1 Physical Placement
The HV-2000C controller should be placed in a location where the front panel controls
can be viewed and accessed. The ventilation holes on the sides should not be blocked.
2.2 Pneumatic System
NOTICE
It is imperative that the air supplied to the HV-2000 is clean and 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).
Air In: Referring to Figure 2-1, connect an independently regulated and filtered main air
source to the rear of the HV-2000C controller. Use a 40-micron filter (at minimum). The
air must be clean and dry, and at a pressure of 70 to 100 psi (0.48 and 0.70 MPa).
Jet Pressure: The HV-2000 jet is supplied with a 6-mm OD air tube and terminates with
a slip connect coupler. Connect this tube to the JET connector on the rear of the
controller. Normal jet air operation is usually between 40 and 60 psi (0.28 and 0.41
MPa).
Fluid Pressure: Pressure to the dispensing fluid is supplied through a 4-mm OD tube
with a locking bayonet coupler. Connect this tube to the FLUID PRESSURE connector
on the rear of the controller.

2.3 Electrical Interface
Four cable connections are on the rear of the Advanjet controller: Power cord, RS-232,
Jet, and Digital I/O, as shown in Figure 2-2. To assure 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 straight International female connector on one end and a country-specific
plug at the other end. Advanjet is prepared to supply cord sets for the USA, for the UK
(part no. 121057), and a standard Euro connector (part no. 121056).
RS-232: The Advanjet software requires an RS-232C communication interface with the
Advanjet controller. If your computer does not have an RS-232C port, use a USB to RS-
232C converter cable with the drivers that come with the cable. Advanjet can supply an
RS-232C-to-USB cable and corresponding driver.
Jet: The Jet cable is a high-density HD-15 cable and should be attached directly to the
HV-2000 Jet and the controller.
I/O (for HV-2000C): The robot’s controller uses the input/output cable to trigger the
HV-2000 to fire the sequence of drops programmed into the Advanjet controller. The I/O
cable should be connected directly to the host robot’s controls. A male DB-26 connector
is required to interface with the I/O cable. The Advanjet controller has an internal
nonvolatile memory that retains the jet parameters that were downloaded into the
controller. The controller provides 6 TTL trigger lines to control jet operations. See
Section 2.4 for more details.

2.4 Input / Output Connections
A standard, 5-foot 26-pin Input/Output cable is supplied with the HV-2000C. The table
below describes the I/O connector pin assignments. The I/O is configured for the inputs
to be pulled down to GND. When the specific input is triggered, the Advanjet controller
will activate the corresponding preprogrammed Recipe # shown.
Pins 1 through 6 are outputs from the robot to the Advanjet controller.
They can be TTL outputs capable of sinking 2 mA of current,
or they can also be relay contacts.
Pin 7 outputs a busy status flag from the Advanjet controller to the robot.
Pin 8 is an external interrupt used to remotely stop a dispensing program.
Pins 9 and 14 are Isolated Ground.
Pins 18-26 are alarms from the heater and pressure sensors.

3.4 LCD Display and Selection Keys
HV-2000C front panel programming and operation uses
the LCD display and input keypad, highlighted in Figure
3-11 at right. Eight basic settings can be input from the
main LCD menu. The selected setting is indicated by a
blinking cursor.
Figure 3-12 shows the cursor selecting the
Recipe #. Use the LEFT/RIGHT keys to
move the cursor and the UP/DOWN keys
to increment the values.
3.5 Jet Setting from the Front Panel
The eight jetting parameters on the LCD display can be programmed from the input
keypad.
Recipe: Select the recipe number from 1 to 6. Each recipe consists of the Trigger mode,
Refill time, Dwell time, Refill+ time (―first drop‖ adjustment), and the number of drops to
dispense. Up to 6 dispensing recipes can be programmed and saved in the controller.
Trigger: There are two Trigger modes—PULSE or LEVEL.
In the PULSE mode, the number of drops dispensed per trigger signal is
specified in the Drops setting. For example, if a recipe has set Trigger to PULSE
and Drops to 5, the jet will dispense 5 drops per Trigger signal. Pressing the
Trigger button in PULSE mode sends a Trigger signal and the jet will dispense 5
drops.
In the LEVEL mode, the jet will dispense drops nonstop until the Trigger signal
retreats—the Drops count is ignored. Pressing the Trigger button in LEVEL
mode causes LEVEL mode to be ignored, and the jet will dispense the number of
drops specified in the Drops.
Jet: Use this to CLOSE or OPEN the Jet valve.
Htr Timer (min): The Heater Off timer automatically turns off the heater after the Jet
has been idle for the specified number of minutes. This feature is useful if materials will
be adversely affected by long periods of heating. For example, some materials can be
―cured‖by high temperature while sitting in the nozzle chamber for a long period of idle
time. If Htr Timer is set to zero, the Heater Off timer is not activated.

3.5 Jet Setting from the Front Panel (Continued)
Refill (msec): Refill time is the time required for the material to flow into the nozzle after
each drop is ejected. Refill is set in msec with 0.1 msec resolution. Section 6.1 - Timing
Recipe Parameters provides a detailed explanation of Refill Time.
Dwell (msec): Dwell time is the time required for the material to flow out of the nozzle
and form a drop. Dwell is set in msec with 0.1 msec resolution. Section 6.1 - Timing
Recipe Parameters provides a detailed explanation of Dwell Time.
Refill+ (msec): Sometimes the jet requires a little extra time for the first drop to be
ejected, depending on the material or if the jet is idle for a period of time. Refill+ time is
added to Refill time to adjust the size and quality of the first drop. In PULSE mode,
Refill+ time applies to each drop; in LEVEL mode, Refill+ time applies to just the first
drop. Detailed explanations can be found in Section 6.2 –Programming Timing Recipes
(Adjust Refill Time for First Drop), and also Appendix 1: First Drop Compensation.
Drops: Specify the number of drops to be dispensed. To dispense a single drop per
trigger signal, enter 1. To dispense 10 drops per trigger signal, enter 10.
Note: If the Advanjet controller software is being used and values are changed using
the front panel display, the changes will not be transferred to the Advanjet controller
software. Also, the front panel values can be overwritten each time you start the
Advanjet software program. The warning below will be displayed. It is recommended to
write down any recipe changes made from the front panel and then enter them into the
software to synchronize.
