SITRANS LR250 (HART)
Operating Instructions, 01/2014, A5E32220602-AB
125
Maximum mA limit (2.6.5.)
Prevents the mA output from rising above this maximum level for a measurement value. This
does not restrict the Fail-safe or Manual settings.
Values
Range: 3.8 to 20.50 (mA)
Default: 20.50 (mA)
mA Output Value (2.6.6.)
Allows you to use a simulated value to test the functioning of the loop. You can enter 4 mA, 20
mA, or any other user-defined value within the range.
Values
Range: 3.56 mA to 22.6 mA
Read Only unless Current Output Function (2.6.1.) is set to Manual.
Related parameter
Current Output Function (2.6.1.)
1. First set
Current Output Function (2.6.1.)
to
Manual.
2. Enter the desired mA value in mA Output Value.
3. After completing the test, remember to reset
Current Output Function (2.6.1.)
to the previous
setting.
Via SIMATIC PDM:
Open the menu Device – Loop Test. For more detail, see Loop Test (Page 82).
Linearization (2.7.)
Volume (2.7.1.)
Carries out a volume conversion from a level value.
