5.6.3 Set supply cable length (wall mounting - optional)
For accurate temperature measurement when installed with remote display, the supply line length and cross-section must be
entered to calculate the compensation of the lead resistance.
The lead length should be changed in the following menu:
Basic EF b.EF
Basic Adv. Functions
t.CLk
Pt100 lead length
Cable Length __M
0M - 20M
Selection menu
Setting range:
0 m…20 m
Measuring cable length for compensating the Pt100 supply line resistance
Note:
– Since the go-and-return line must be considered, double the cable length!
5.6.4 Set supply cable cross-section (wall-mounting - optional)
Enter the line cross-section for the supply line here:

5.6.5 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 or tEMP .

Options:

The options are:
Err 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 LEDs 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.
