SITRANS LR250 (HART)
122 Operating Instructions, 01/2014, A5E32220602-AB
Fail-Safe mA Value (2.5.3.)
Note
•
The default settings are dependent on standard or NAMUR NE 43-compliant device.
•
Material Level (2.5.1.)
must be set to
VALUE
to enable the Fail-Safe mA 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
Range
3.56 mA to 22.6 mA
Default
22.60 mA
3.58 mA
Analog Output Scaling (2.6.)
Current Output Function (2.6.1.)
Note
•
Level
,
space
, and
distance
, have different reference points.
•
Use caution when changing Current Output Function while the device is connected to a
HART network. Current Output Function controls the primary value and the loop current
for the device.
•
Current Output Function also affects the secondary, tertiary and quaternary variables in a
HART network.
Can be set to either
Level, Space, Distance,
or
Volume
. (The device can carry out a volume
calculation only after a vessel shape has been specified.)
