6.6.2
Example universal input 1
Procedure
1.
Connect the transmitter, as described in the "Connecting signal inputs" section.
2.
Press the <PAR> button for 5 seconds. This opens the parameter menu.
3.
Use the and buttons to select the parameters P.26 to P.29 associated with the
universal input.
Example: If the external transmitter is connected to terminals 55 to 58, select parameter
P.26.
4.
Using the and buttons, set the associated parameter value. If, for example, a
transmitter with an output signal 0 to 20 mA is connected, set the parameter value "0-20".
5.
Next the alarm limit is set. This is done via one of the parameters P.30 to P.33. Again use
the and buttons, to select the associated parameter. In our example, parameter
P.30 is to be selected for universal input 1.
6.
Using the and buttons, set the desired parameter value. The parameter value set is
displayed to the left in the middle section of the digital display.
7.
As a final step, you must set the digital output at which the alarm is to be displayed. This
is done via one of the parameters P.34 to P.37. Use the and buttons to select the
associated parameter. In our example, parameter P.34 is to be selected for universal
input 1.
8.
Using the and buttons, set the desired parameter value. For example, "do1" for
displaying the alarm at digital output 1.
9.
Press the <MEAS> button to return to the measuring menu.
Note
Alarm limit
The alarm limits set via parameters P.30 to P.33 are only effective with analog inputs. With
digital inputs, the values given in the "Specification" apply as switching thresholds.
