Values in italics are factory defaults.
Other System Variables
After the calibration and automation path programming is complete and the desired bead profiles have been
achieved, verify that the following variables are set.

Appendix B , PrecisionFlo LT User Interface .
An Alarm will cause the fault present signal to activate and the dispenser ready signal to drop out. This
is something considered by the user to be a major fault, one which should cause the system to stop
dispensing.
A Warning will cause the fault present signal to activate and the dispense ready signal to stay on. This
is something considered by the user to be a minor fault, one which will warn the user but will continue
dispensing even if the bead profile is degraded.
