Choose the desired signal level to cause a failure condition. The choices are:

Actual

Normal: The absolute measurement sig- nal will be sent to the analog output.

Adjust 0V: Used to set the display equal to the analog output for 0V and 0 mA. Life zero signals (4-20 mA and 2-10V) are set automatically and cannot be adjusted.

Adjust 10V: Used to set the display equal to the analog output for 10V and 20 mA.

Select the “Fine adjustment for 0% out- put” and/or “Fine adjustment for 100% output” lines with the ↵ or → key. Adjust to the desired value with the ↑ or ↓ key and confirm with the ↵ key. The range of values are:

BeginOfRange

EndOfRange

BeginOfRange-10%

BeginOfRange+10%

3000 to 6000 for 0% (default 4096)

600 to 1000 for 100% (default 819)

The last three lines of the “Analog Output Setup” menu are display only for configu- ration values of the analog output.

Signal name: The name of the sig- nal chosen in the “Choose signal” menu.

Current signal value: The current value of the variable.

Source module: The name of the module chosen in the “Choose sig- nal source module” menu.Pressing the F5 (More…) key changes to the submenu “Special Scaling for Con- centration Signal.”

This menu allows for the setting of each of the 8 outputs to be the same as the range limits “Yes” or as set on the previ- ous menus.

See section 3-5c for setting the range lim- its.

Pressing F5 (More…) changes to the submenu “Special Scaling for Concentra- tion Signal”.

3-28 Operation
