After mounting, wiring and setting check whether the unit operates
correctly
Faults displayed during operation
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.

Flashing: short circuit in the switching output.
Overload (above measuring range of the sensor).
Underload (below measuring range of the sensor).
*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.
Flashing: internal fault
