LFP Inox

5 Advanced functions

5.1 Expert Mode

To enter into a special functions menu, expert mode needs to be activated first.
Log in to expert mode
Access the PASSW menu using the arrow pushbuttons
■
Enter password 000537 (LFP on the mobile keypad: L=5 / F=3 / P=7). Expert mode may be locked
■
again if the password is entered incorrectly or if the power supply is disconnected.

5.2 Filtering the measured values

Activating filtering
Smoothing of the measured value; e.g., in the case of ripples on level surfaces For fast level
■
changes, the average of the measured values over X seconds is indicated.
Set parameters in the Set filters menu
■
The possible values are Off, 400 ms, 600 ms, 1,000 ms, 1,400 ms, 2 s, 5 s, 10 s.
■
Maximum change of level (plausibility check)
For applications which cause level jumps as a result of significant interference on the LFP. Enter
■
the max. level dynamic value in the application, or the maximum permissible rate of change of the
level
Log in to expert mode (Please see „5.1 Expert Mode")
■
Reduce parameters in the EXPRT-CONFIG-MaxCol menu
■
AnySpd (50 cm/s) (default), 10 cm/s, 5 cm/s, 2 cm/s
■
Note:
■
For MeasMd = HiSpd, all max. rates of change are possible
○
For MeasMd = HiAcc, max. is 10 cm/s
○

5.3 Testing the configuration

Testing outputs
Switching/analog outputs can be simulated. This allows you to check the wiring and signal values
■
at the connected systems, such as the PLC, relays, and lamps.
Configuration
Activate the Qx switching output
■
Set parameter to QxOn in the QxMENU-SimQx menu
○
Further options
○
QxOff = switching output off
▫
QxNorm = switching output in measuring operation
▫
QxOn = switching output is active
▫
Note: The simulation is automatically deactivated if the supply voltage is interrupted.
■
Activate the QA analog output
■
Set parameter in menu QAMENU-SimCur or SimVol on desired signal value.
