Overview of measuring ranges

Measuring ranges
The device lets you set measuring ranges permanently or switch them over automatically.
Contrary to the permanent setting, the measuring range follows the current measured value
with automatic switchover.
You can define up to four measuring ranges for each component. The start-of-scale values
and the end-of-scale values are assigned to the low or high value of the analog output
(scaling of the analog output). The following settings are available:
● NAMUR
● 4 to 20 mA or 20 to 4 mA
● 0 to 20 mA or 20 to 0 mA
Autoranging
Setting requirements
The following requirements must be met before autoranging can be activated:
● At least two measuring ranges are set and activated for each component.
● The measuring ranges border on each other or overlap.
● The spans of the set measuring ranges must increase (ms
Based on these requirements, the following two measuring range types described below are
derived for autoranging.
Quick Start
Compact Operating Instructions, 01/2013, A5E31805656-01
– Current range as per NAMUR NE043: 4 to 20 mA
– Alarm at <3.6 mA and >21 mA
Only one activated measuring range is used for autoranging.
