Loop-Test; Configuration Flag Reset; Master Reset; Wear - Siemens Sitrans LR200 Instruction Manual

Loop-Test

Note: The simulated AO (Analog Output) value influences output to the control system.
Allows you to input a simulated value (4 mA, 20 mA, or a user-defined value) in order to
test the functioning of the mA connections during commissioning or maintenance of the
device. (The range is 3.56 mA: see
To simulate a user-defined mA value:
1) Open the menu Device – Loop-Test.
2) Select Other, enter the new value, and click on OK. The message 'Field Device fixed
at [new value]' appears. Click on OK. The Loop-Test window remains open.
3) When you are ready to end simulation, select End and click on OK to return the
device to the actual output value.

Configuration Flag Reset

To reset the configuration flag to zero, open the menu Device – Configuration Flag Reset and
perform a reset.
