Operating Instructions, 05/2019, A5E32337676-AE
7.2.5.4
Control range; lower limit (min mA limit) (2.6.4.)
Description
Prevents the mA output from dropping below this minimum level for a measure-
ment value. This does not restrict the Fail-safe or Manual settings.
Values
Range: 3.8 to 20.5 (mA)
Factory setting
3.80 (mA)
7.2.5.5
Control range; upper limit (max mA limit) (2.6.5.)
Description
Prevents the mA output from rising above this maximum level for a measure-
ment value. This does not restrict the Fail-safe or Manual settings.
Values
Range: 3.8 to 20.5 (mA)
Factory setting
20.50 (mA)
7.2.5.6
mA output value (2.6.6.)
Description
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
Factory setting
Read Only unless CURRENT OUTPUT FUNCTION (2.6.1.) is set to Manual

Current output function (2.6.1.) (Page 104)
How to test loop function:
1.
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.
To test loop function via SIMATIC PDM, open the menu Device – Loop Test. For more detail,
refer to Loop test (Page 71).
7.2.6
Linearization (2.7.)
7.2.6.1
Volume (2.7.1.)
Carries out a volume conversion from a level value.
