Blocking distance (factory setting):
with rod probes up to 6 m (20 ft): 200 mm (8 in)
The specified blocking distances are preset on delivery. Depending on the application these settings can
be changed.
When using a spray ball, the blocking distance must be at least 50 mm (2").
For rod and rope probes and for media with DC > 7 (or generally for stilling well/bypass applications)
the blocking distance may be reduced to 100 mm (4").
Within the blocking distance, a reliable measurement can not be guaranteed.
A safety distance SD can be defined in addition to the blocking distance. A warning is generated if the
level rises into this safety distance.

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
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.
