Endress+Hauser Liquiphant FTL62 - Protocol Specific Data and Heartbeat Technology

Liquiphant FTL62 HART Technical data
Endress+Hauser 53
15.2.5 Switch output
Preset switching delay times can be ordered:
• 0.5 s when the tuning fork is covered and 1.0 s when the tuning fork is uncovered
(factory setting)
• 0.25 s when the tuning fork is covered and 0.25 s when the tuning fork is uncovered
(fastest setting)
• 1.5 s when the tuning fork is covered and 1.5 s when the tuning fork is uncovered
• 5.0 s when the tuning fork is covered and 5.0 s when the tuning fork is uncovered
The user can also set the switching delays for when the fork is covered and uncovered
in the range from 1 to 60 seconds independently of one another.
(Operation via display, Bluetooth or FieldCare, DeviceCare, AMS, PDM)
15.2.6 Ex connection data
See safety instructions (XA): All data relating to explosion protection are provided in
separate Ex documentation and are available from the Downloads Area of the
Endress+Hauser-website. The Ex documentation is supplied as standard with all Ex
devices.

HART device variables (preset at the factory)
The following measured values are assigned to the device variables at the factory:
Device variable Measured value
Primary variable (PV) parameter (Primary variable)
1)
Point level detection
2)
Secondary variable (SV) parameter (Secondary variable) Sensor frequency
3)
Tertiary variable (TV) parameter (Third variable) Fork state
4)
Quaternary variable (QV) parameter (Quaternary variable) Sensor temperature
1) The PV is always applied to the current output.
2) Point level detection is the initial state depending on the fork state (uncovered/covered) and the safety
function (MIN/MAX)
3) Sensor frequency is the oscillation frequency of the fork
4) Fork state is the fork state (Fork covered option/Fork uncovered option)
Choice of HART device variables
• Level limit detection
• Sensor frequency
• Fork state
