HART Loop Converter KFD2-HLC-(Ex)1.D(.**)
Editing device data: Relay
The following illustration shows the exact switching characteristics of the HLC:
8.5.4 Trip point and hysteresis
Please remember the following when entering values for
Trip point
and
Hysteresis
:
•
Both values must be entered as floating decimal numbers in the unit selected under
Unit
section 8.1.4 and 8.2).
•
The selected hysteresis must be > 1 % of the trip point to prevent the relay from vibrating.
