correctly
Faults displayed during operation
Overload (above measuring range of the sensor).
Underload (below measuring range of the sensor).
Flashing: short circuit in the switching output.

*The output is switched off as long as the short circuit exists.
The faults SC1, and Err are indicated even if the display is deactivated.
Diagnostic function (according to DESINA specification)
Output 1 is used as a diagnostic output if OU1 = dESI.
• If there is no fault, the output is switched and carries UB+ (if P-n =
PnP) or UB- (if P-n = nPn).
• In case of malfunctions the output becomes inactive. The following
malfunctions are detected:
Undervoltage (starting with 18V); overvoltage (starting with 33V);
temperature at the process connection too high ((> 150°C) / too
low (< -30°C); intrinsic temperature of the unit too high (> 100°C) /
too low (< -30°C); RAM fault.
