7.2.4.3 Level (2.5.3.)
Note
•
The default setting depends whether your device is a standard or NAMUR NE 43-
compliant device.
•
Material Level (2.5.1.) must be set to VALUE to enable the Level value to be reported.
Allows the user to define the mA value to be reported when the Fail-safe timer expires.
Device type STANDARD NAMUR NE43-COMPLIANT
Values 3.56 mA to 22.6 mA 3.56 mA to 22.6 mA
Factory setting 22.60 mA 3.58 mA
7.2.5 Analog output scaling (2.6.)
7.2.5.1 Current output function (2.6.1.)
Allows CURRENT OUTPUT FUNCTION (2.6.1.) to be set independently from SENSOR
MODE (2.2.2.). For example, Sensor Mode may be set to Level and Current Output Function
set to Distance.
