Start Of Scale (4 Ma Setpoint) (2.6.2.); Full Scale (20 Ma Setpoint) (2.6.3.) - Siemens SITRANS LR200 7ML5422 Operating Instructions Manual

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).

Operating Instructions, 05/2019, A5E32337676-AE
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).
Range: –999999 to +999999
0.00 m (set to value corresponding to 0% as defined by Current Output Func-
tion)

Current output function (2.6.1.) (Page 104)
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).
Range: –999999 to +999999
