Display	–	During normal functioning
Display	F – Code	Fault detected. Displayed alternatively to the error code. See next “Fail condition Table”

Configuration errors

C: Incorrect configuration of the system (the flashing led together with the C indicates the incorrect type of configuration). See Technical manual
L: Muting light not present or fault
U: Incorrect “SYSTEM STATUS” or overload signal connection
E: External contact enabling/disabling signal missing or contactors feedback missing
II: Unstable Muting sensors signals or Barrier configured for 2 sensors but found 3 or 4 sensors (the corrispondent led flashes)
