Device Outputs
Table A- 4 Function group Device outputs parameters
4.1 Analog Out
1, 2
Analog output 4 to 20mA with HART
communication
4.1.1 Current limit Upper limit of analog current 22 mA 20 ... 22.5mA
4.1.2 Error signal Output current in case of failure.
With the setting "Hold ..s" a current of 3.6
mA is only output in the case of a longer
failure, shorter failures are bridged with
output of the last valid current
3.6 mA
•
3.6mA, 22mA, 24mA,
•
Hold continuous,
•
Hold 5s, 20s, 40s, 60s,

4.1.3 Current range Selecting the current range at the analog
output on which the measuring range
(menu 3.1.2) is shown.
For the setting 0 to 20 mA the failure
signal (menu 4.1.2) must be set to 22 or
24 mA.
