NOTICE

Disabling normal error handling

Disabling normal error handling and analysis could potentially cause dangerous operat-
ing states, dangers to the user or machines. Before using this option, review the hazard
potential within the process. With this setting, Bühler Technologies GmbH assumes no li-
ability for injuries to health or material damage caused by this setting.

5.6.1 Disabling normal error handling

Here you can enable/disable normal error handling and analysis

The function Disable error handling (

Err.h

) is used to disable normal error handling and analysis. This may pose dangers to the

user or machine.

___

no - YES

Confirm

The options are:

Disables normal error handling.

Enables normal error handling (default)

Important note: When exceeding the measuring range or if sensor errors occur, the measurement
will be frozen and all six LEDs in the status bar will blink. When the measurement returns to the
permissible range the LEDs will stop blinking and the display will refresh again as usual.

5.6.2 Define switching outputs

Here you can define the switching outputs.

Use the “Define switching outputs” function to define the switching outputs (

r.ou1

 and

 r.ou2

). The switching outputs can be

configured as 

Err

oil

 and 

tEMP 

.

The options are:

Err

oil

TEMP

Note:

– Switching outputs 1 and 2 can alternatively be wired as error indicators. In this case the output

will be connected as a NC contact which opens when exceeding the range or if an error occurs.
The LED assigned to this output will generally not be activated, as all 6 LED's in the status bar
will blink if an error occurs.

– When defining a switching output as an error indicator it will no longer be an option for normal

switching output settings.
