SITRANS LUT400
178 Operating Instructions, 07/2019, A5E33329501-AC
9.2.5.3 4 mA Setpoint (2.5.3.)
Sets the process level corresponding to the 4 mA value. 4 mA always defaults to 0 m, and
Current Output Function (2.5.1.) (Page 176) determines the type of measurement. [See
Current Output Function (2.5.1.) (Page 176) for an illustration.]
Values
Range: Level, Space, Distance,
Head: 0.000 to 60.000 m
Volume: 0.0 to Max. Volume
Flow: 0 to Max. Flow
Default:
0
(set to value corresponding to 0% as defined by Current Output Function
and associated units)
● Enter the reading that is to correspond to a 4 mA output.
● Units are defined in Units (2.1.1.) (Page 168) for Level, Space, Distance, or Head, and in
Flowrate Units (2.15.3.7.) (Page 233) for Flow. Volume units are converted from a level
value.
9.2.5.4 20 mA Setpoint (2.5.4.)
Sets the process level corresponding to the 20 mA value. 20 mA always defaults to 60 m,
and
Current Output Function (2.5.1.) (Page 176) determines the type of measurement. [See
Current Output Function (2.5.1.) (Page 176) for an illustration.]
Values
Range: Level, Space, Distance,
Head: 0.000 to 60.000 m
Volume: 0.0 to Max. Volume
Flow: 0 to Max. Flow
Default: Level, Space, Distance,
Head:
60.000
Volume:
Max. Volume
Flow:
Max Flow
(set to value corresponding to 100% as defined by Current Output Function and
associated units)
● Enter the reading that is to correspond to a 20 mA output.
● Units are defined in Units (2.1.1.) (Page 168) for Level, Space, or Distance, or Head, and
in Flowrate Units (2.15.3.7.) (Page 233) for Flow. Volume units are converted from a level
value.
9.2.5.5 Minimum mA Limit (2.5.5.)
Prevents the mA output from dropping below this minimum level for a measurement value.
This does not restrict the Fail-safe or Manual settings.
Values
Range: 3.5 to 22.8 mA
Default: 4.0
