10 Operation
After power on, the unit is in the Run mode (= normal operating mode). It carries
out its measurement and evaluation functions and provides output signals accord-
ing to the set parameters.

10.1 Reading of the set parameters
Press [Mode/Enter] until the requested parameter is displayed. ►
Press [Set] briefly. ►
The unit displays the corresponding parameter value for about 15 s. After >
another 15 s the unit returns to the Run mode.
10.2 Fault indication
[OL] Temperature too high (measuring range exceeded by more than 3% of the final
value of the measuring range).
[UL] Temperature too low (measuring range below the final value of the measuring
range by more than 10%).
[Err] No temperature sensor connected.•
Fault or short circuit in the temperature sensor, wire break.•
Detection zone is exceeded (T < -60°C or T > +160°C).•
[SC1] Short circuit in OUT1*
[SC2] Short circuit in OUT2*
[SC] Short circuit in both switching outputs*
[Loc] Setting pushbuttons of the unit locked, parameter change rejected.
[SLoc] Unit locked via software, parameter change rejected.
[PARA] Settingvalueofaparameteroutsidethevalidrange→theunitisnotreadyfor
operation. The error may occur with IO-Link parameter setting.
If an invalidly set parameter is activated, [PARA] is displayed instead of the
parameter value.
*The output concerned is switched off as long as the short circuit exists.
The messages Err, PARA and SC1 are shown even if the display is switched off.
