Antenna Offset (2.3.8); Current Output (2.4); Loop Current Mode (2.4.1); Loop Current Value In Multidrop Mode (2.4.2) - Siemens SITRANS LR500 Series Operating Instructions Manual

Parameter assignment
9.2 Setup (2)
Setting
Default
9.2.3.8

Antenna offset (2.3.8)

Sets offset required if electronics module is replaced. Consult your local Siemens representative
for support.
Setting
Default
9.2.4

Current output (2.4)

9.2.4.1

Loop current mode (2.4.1)

Sets operation of Loop current for HART multidrop mode.
Setting
Default
The device is in loop current mode by default. Disabling parameter "Loop current mode"
will result in a fixed loop current setting for multidrop operation (see Loop current value in
multidrop mode (2.4.2) (Page 120)).
9.2.4.2

Loop current value in multidrop mode (2.4.2)

Sets mA value for loop current in HART multidrop mode.
Setting
Default
9.2.4.3

Damping value (2.4.3)

Sets the damping (filtering) of the PV to smooth out response to sudden changes in
measurement.
An increase of damping increases response time of device, and affects digital value and loop
current. If output values are noisy, increase parameter "Damping value". For faster response
time, decrease parameter "Damping value". Find a value that meets requirements of signal
stability and response time.
