6. Trigger Map: Displays the assignment of the trigger input to the dispensing
recipes. For example, in Figure 5-2 below, input trigger signal from I/O Pin 1 is
used to activate Recipe #1. The BusyFlag (I/O Pin 7) is an output signal that the
external controller/robot can use to monitor the Jet status. When the Jet is idle,
the BusyFlag signal is set to high; when the Jet is activated, the BusyFlag signal
is set to low. An external controller/robot can use the BusyFlag signal to
synchronize the timing for the next Recipe trigger.
7. Download Settings: Click on this button to download timing recipes, drop count,
and trigger mode for the six recipes, and the settings for the temperature
controller. The download command will overwrite the current settings in the
controller.
8. Heater Options:
Heater On: Sets the heater on the controller to ON or OFF.
Set temperature to: Enters nozzle heater value (in degrees Celsius).
9. Heater Off Timer: This automatically turns off the heater after setting a specified
Jet idle time in 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 when sitting in the nozzle chamber for a long period of idle
time. A value of zero means the Heater Off timer option is not activated.
