Signal on alarm
Depending on the interface, failure information is displayed as follows:
• Current output (for HART devices)
– Failsafe mode selectable (in accordance with NAMUR Recommendation NE 43):
Minimum alarm: 3.6 mA
Maximum alarm (= factory setting): 22 mA
– Failsafe mode with user-selectable value: 3.59 to 22.5 mA
• Local display
– Status signal (in accordance with NAMUR Recommendation NE 107)
– Plain text display
• Operating tool via digital communication (HART, PROFIBUS PA, FOUNDATION Fieldbus) or
service interface (CDI)
– Status signal (in accordance with NAMUR Recommendation NE 107)
– Plain text display
Linearization
The linearization function of the device allows the conversion of the measured value into any unit of
length or volume. Linearization tables for calculating the volume in cylindrical tanks are pre-
programmed. Other tables of up to 32 value pairs can be entered manually or semi-automatically.
Galvanic isolation
All circuits for the outputs are galvanically isolated from each other.
