Siemens LU01 Transducer Scanning P725 to P729, P713 Echo Lock Window, P726 Level System Sync

Parameters

Example:

Setting

•P711 = 2, material agitator

•P712 = 5:2

Result

•a new reading will not be validated unless five consecutive measurements higher or two consecutive measurements lower than the current reading occur

•Resetting P711 returns P712 to the respective preset values

P713 Echo Lock Window

Adjusts the size of the Echo Lock Window.

Values	Range: 0.000 to 9999
	Preset: 0.000
Altered by	•	P003 Maximum Process Speed
Related	•	P005 Units
	•	P711 Echo Lock

The Echo Lock Window is a distance window (units P005) centred on the echo and used to derive the Reading. When a new measurement is in the window, it is re-centred and the new Reading calculated. Otherwise, the new measurement is verified by Echo Lock (P711) before the reading is updated.

When 0 is entered the window is automatically calculated after each measurement. For slower P003 Maximum Process Speed values the window is narrow, for faster P003 values the window becomes wider.

Transducer Scanning (P725 to P729)

P726 Level System Sync

Enables the System Sync on the terminal block.

Values	0		not required
	1	*	synchronize level monitors

Use this if another level measurement system is mounted nearby, and they are wired together on the Sync terminal.

P727 Scan Delay

The delay, in seconds, between measurements from transducer points .

Values	Range: 0.000 to 60.00
	Preset: 5.0
Altered by	•	P003 Maximum Process Speed
Related	•	P001 Operation
