Operation
The diagnostics mode is available at all times. The gun can still be
triggered while the display shows the diagnostics information.
Pressing the Nordson key at any time while in the diagnostics mode results
in an automatic exit from this mode and a return to the previous operating
mode.
NOTE:
Do not power off the system unless instructed. Error codes are
erased when the system is powered off.
