After mechanical and electri-
cal installation, start-up, then
the device performs a self-
test and is ready for use.
The Wizard automatically dis-
plays parameter setup steps
on-screen.
If false parameter value is input-
ted (e.g. outside limits) an error
message / icon occurs, and after
10 seconds the screen switches
to HELP function.
If error persists, download log file
using PACTware and send to e-
mail address given on back rear
