Gun Overview
Error Display
If the Smart module loses communication with
the power supply, the Error display appears, the
Hz indicator turns red, and the Smart module is
disabled. See Fig. 3, and Table 1 on page 11.
This can occur in Operating Mode or Diagnostic
Mode. See Electrical Troubleshooting, page
Communication must be restored to make the Smart
module functional.
NOTE: It takes 8 seconds for the Error display to

seconds before spraying to ensure that an Error
condition has not occurred.

display will not appear.
