HV-2000C front panel programming and operation uses

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.

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, 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.
