5.1 Simulation
To simulate a certain filling level, you can call
up the function “Simulation” in the oscillator, in
the adjustment program VVO or in the HART

You hereby simulate a certain current. Re-
member that connected instruments, such as
e.g. a PLC, react according to their settings
and that alarms may be triggered or system
functions activated.

The instrument is maintenance-free.
5.3 Repair
Repair work requires opening the instrument
to correct defects. For safety and warranty
reasons, all internal work on the instruments,
apart from that involved in normal installation
and connection, must be carried out only by
qualified VEGA personnel.
In case of a defect, please return the affected
instrument with a short description of the error
to our repair department.
Faults are short-term malfunctions of the in-
strument which are caused by wrong adjust-
ment or defects in the sensor or the
connection cables.
Faults, their possible causes and their rectifi-
cation are explained under “5.4 Fault rectifica-
