1 Current Loop Monitoring

Enable or disable the monitoring of the
4-20 mA current signal. Monitoring checks whether the set cur-
rent is actually flowing in the current loop, and signals an error
if any deviation is detected.
You have the following setting options:
• ENABLED
Monitoring is enabled (default setting).
Unless there are compelling reasons, you should keep this set-
ting. The setting is automatically enabled when the Safety
Mode is selected.
• DISABLED
Monitoring is disabled. The HART Communicator outputs a cor-
responding message.
Tip
In case of a gross deviation or loose contact, monitoring may have
the effect that the fault condition can only be reset by a software
reset. The software reset menu can be done in the menu
