6.5 System commands
Start simulation
Starts the simulation mode. The level set under the parameter [S.Lvl] is
simulated.
Stop simulation
Stops the simulation.
Reset to factory settings.
Restore factory settings (all parameters).
On delivery the unit is not operational.
For further information, please refer to the IODD description
parameter descriptions of the used parameter setting software.
6.6 Example parameter setting
•
The unit is to monitor the level in an 8 m high tank.
•
The unit is mounted in a nozzle (nozzle height: 150 mm).
•
No tank offset is to be used.
•
The medium is aqueous (beer or milk).
•
The unit to be used is [m].
•
Output OUT2 is to be configured as an analogue output.
u
Reset the unit to factory settings:
Execute the system command [Reset to factory settings].
w
This serves to avoid incorrect settings and establish a defined start situation.
u
Set the unit:
(parameter [uni] = [m]).
u
Set the tank height:
parameter [Reference height] = [8.000] m.
w
The tank bottom may be interpreted as a low level.
In this case:
u
Reduce the reference height and configure a tank offset.
u
Define the upper blind zone:
parameter [Upper blind zone] = [200] mm.
w
This setting is used to block out disturbing echoes from the nozzle.
u
Deactivate damping:
parameter [dAP] = [0.0] s.
During a test phase, this can be useful to quickly detect level changes.
u
Reactivate if necessary.
u
Set the delay time for the alert mode to zero:
parameter [Alert mode delay time] = [0] s.
During a test phase, this can be useful to quickly detect incorrect measurements and identify
potential sources of error.
u
Reactivate if necessary.
u
If necessary, adjust the sensitivity (parameter [Detection threshold]), observing the following
instructions Detection quality check (
u
Configure output OUT2 as an analogue output:
[ou2] = [I].
