SITRANS LR200 with mA/HART
Operating Instructions, 05/2019, A5E32337676-AE
105
Notes:
●
Level, space, and distance, have different reference points.
●
Sensor Mode resets Current Output Function to the same setting. To select a different
option, do so after Sensor Mode has been set.
●
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.
●
To modify Current Output Function via SIMATIC PDM, open the menu Device – Select
Analog Output. For more detail, refer to Select analog output (Page 71).
7.2.5.2
Start of scale (4 mA setpoint) (2.6.2.)
Description
Sets the process level corresponding to the 4 mA value. 4 mA always defaults to
0, and Current Output Function determines whether this is a Level, Space, Dis-
tance, or Volume measurement. For an illustration, refer to Current output func-
tion (2.6.1.) (Page 104).
Values
Range: –999999 to +999999
Factory setting
0.00 m (set to value corresponding to 0% as defined by Current Output Func-
tion)

Current output function (2.6.1.) (Page 104)
Note
Enter the reading that is to correspond to a 4 mA output. Units are defined in Units (2.2.1.)
(Page 99) for Level, Space, or Distance. Units are unspecified for Volume.
7.2.5.3
Full scale (20 mA setpoint) (2.6.3.)
Description
Sets the process level corresponding to the 20 mA value. 20 mA always defaults
to 100%, and Current Output Function determines whether this is a Level,
Space, or Distance measurement. For an illustration, refer to Current output
function (2.6.1.) (Page 104).
Values
Range: –999999 to +999999
Factory setting
20.00 m (set to value corresponding to 100% as defined by Current Output
Function)
