HART Loop Converter KFD2-HLC-Ex1.D(.**)
Configuration
Defining the Trip Point
1. Enter the starting point as a floating point figure. For entering floating point figures, 
see chapter 4.2.4. The defined unit from the Unit menu is used as the unit. 
See chapter 4.2.5.
2. Confirm your entry with OK.
Defining Hysteresis
Make sure during input that the hysteresis is at least 1 % greater than the trip point. 
This avoids "fluttering" of the relay.
1. Enter the hysteresis as a floating point figure. For entering floating point figures, 
see chapter 4.2.4. The defined unit from the Unit menu is used as the unit. 
See chapter 4.2.5.
2. Confirm your entry with OK.
Activating the Restart Inhibit
The restart inhibit is used to prevent momentary limit value violations from not being noticed
by operating personnel.
1. Use the  or  buttons to select On.
2. Confirm your selection with OK.
The relay status is retained after switching the relay.
3. If you would like to reset the relay status, press the ESC or
button or restart the device.
The relay is reset. Exception: there is a limit value violation.
Defining the Response Delay
Inputting a response delay > 0 s prevents momentary limit value violations from triggering an
alarm.
1. To change the time in steps, press the  or  buttons.
Set the time from 0 s to 250 s in increments of 5 seconds.
2. Confirm your entry with OK.
