Application and Setting Notes
Parameter: Unit
•
Recommended setting value (_:103) Unit = °C
You use the setting Unit to specify which physical unit of measurement the measured values represent. The
possible setting values are listed in the settings table.
Parameter: Conversion factor
The (_:104) Conversion factor setting allows you to set the conversion factor for the measuring trans-
ducer.
Parameter: Resolution
•
Default setting (_:108) Resolution = 0.1
The Resolution setting is used to specify the measured value resolution.
Parameter: Range active
•
Default setting (_:107) Range active = false
If you do not activate the Range active setting (no x in the check box), the function operates over the
range -24 mA to +24 mA. The setting of the range for the scaled value goes from a usable range of -20 mA to
+20 mA.
If you activate the Range active setting, then 4 additional settings Upper limit, Upper limit -
Sensor, Lower limit and Lower limit - Sensor appear.
Parameter: Upper limit, Lower limit, Upper limit - Sensor and Lower limit - Sensor
•
Default setting(_:105) Upper limit = 20000 mA
•
Default setting (_:109) Upper limit - Sensor = 100
•
Default setting(_:106) Lower limit = 4000 mA
•
Default setting (_:110) Lower limit - Sensor = 100
If you activate the Range active setting, then 4 additional settings Upper limit, Lower limit, Upper
limit - Sensor, and Lower limit - Sensor appear. The setting Upper limit - Sensor is the
calculated measured value if the input current corresponds to the value in the Upper limit setting. The
setting Lower limit - Sensor is the calculated measured value if the input current corresponds to the
value in the Lower limit setting.
