Liquicap M FMI51 HART Commissioning
Endress+Hauser 53
7.4.3 Function: "Safety settings"
Subfunction: "Cap. empty"
This subfunction displays the measured capacitance during empty calibration in pF.
Subfunction: "Value empty"
This subfunction displays the empty calibration value in %.
Subfunction: "Cap. full"
This subfunction displays the measured capacitance during full calibration in pF.
Subfunction: "Value full"
This subfunction displays the full calibration value in %.
Subfunction: "Parameter okay"
With this subfunction, you confirm that the parameter values displayed under the "Safety
settings II" function are correct.
The "Parameter okay" subfunction has to be confirmed with "Yes" so the device can be
locked for the SIL/WHG operating mode. In addition, the SIL/WHG function value has
to be selected for the "Operating mode" subfunction and "Locked" must be set for the
"Status" subfunction. The device can be unlocked using the special release code. The
release code is "7452".
7.4.4 Function: "Operating mode"
Subfunction: "Operating mode"
With this subfunction, you can switch from the Standard operating mode to the SIL/WHG
operating mode:
• Standard
• SIL/WHG
The following parameters are set to defined values in the "SIL/WHG" operating mode:
• Output damping: Output damping is fixed at 1 s.
• Output on alarm: The "Output on alarm" function is fixed at 22 mA.
In the "SIL/WHG" operating mode, cyclic self-monitoring of the device is like a memory
test, processor test, current output, etc.
Subfunction: "SIL operating mode"
You can lock or unlock the device in this subfunction. No parameters can be changed in the
locked state.
Subfunction: "Status"
This subfunction displays the current locking status of the device.
The following values can appear:
• Unlocked
All writeable parameters can be modified.
• Locked
The device has been locked via the operating menu.
The device can be only unlocked by entering "100" in the subfunction "Code" → 52.
