9.4 Measurementerrorduringlling

Fault description Error pattern Cause Rectication

3. Measured value re-

mains in the area of the

bottom during lling

Level

time

– Echo from the tank bottom

larger than the product echo,

for example, with products with

< 2.5 oil-based, solvents

– Check application parameters

Medium, Vessel height and

Floor form, adapt if necessary

4. Measured value

jumps to ≥ 100 % or

0 m distance

Level

time

– Level echo is no longer

detected in the close range

due to foam generation or false

echoes in the close range. The

sensor goes into overll protec-

tion mode. The max. level (0 m

distance) as well as the status

message "Overll protection"

are outputted.

– Check measuring site: Antenna

must protrude out of the socket

– Remove contamination on the

antenna

– Use a sensor with a more suit-

able antenna

9.4 Measurement error during emptying

Fault description Error pattern Cause Rectication

5. Measured value re-

mains unchanged in

the close range during

emptying

Level

time

– False echo larger than the level

echo

– Level echo too small

– Remove false echoes in the

close range. Check: Antenna

must protrude out of the socket

– Remove contamination on the

antenna

– Minimize interfering instal-

lations in the close range by

changing the polarization

direction

– After removing the false ech-

oes, the false signal suppres-

sion must be deleted. Carry out

a new false signal suppression

6. Measured value

jumps towards 0 %

during emptying

Level

time

– Echo from the tank bottom

larger than the product echo,

for example, with products with

< 2.5 oil-based, solvents

– Check application parameters

Medium type, Vessel height and

Floor form, adapt if necessary

Depending on the reason for the fault and the measures taken, the

steps described in chapter "Setup" must be carried out again or must

be checked for plausibility and completeness.

Should these measures not be successful, please call in urgent cases

the VEGA service hotline under the phone no. +49 1805 858550.

The hotline is also available outside the normal working hours on

seven days a week around the clock.

Since we oer this service worldwide, the support is in the English

language. The service itself is free of charge, the only costs involved

are the normal call charges.

9.5 Exchanging the electronics module

If the electronics module is defective, it can be replaced by the user.
