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.
