3. Operating range
Without special adjustment, the operating
range corresponds to the measuring range.
The measuring range was already entered
with the min./max. adjustment. Generally, it is
useful to choose a slightly wider range
(approx. 5 %) for the operating range than
for the measuring range.
Example:
Min./Max. adjustment: 0.300 … 5.850 m;
adjust operating range to approx.
0.250 … 6.000 m.
4. Adjustment
Under the menu item " Adjustment", you inform
the sensor of the measuring range.
You can carry out the adjustment with or
without medium. Generally, you will carry out
the adjustment without medium, as you can
then adjust without a filling/emptying cycle.
Max.
Min.
100 % (1.270 m) correspond
to 1200 liters
Span (4.58 m)
0 % (5.850 m) correspond
to 45 liters
Error codes:
E013 No valid measured value
- sensor in the warm-up phase
- loss of the useful echo
E017 Adjustment span too small
E036 Sensor program not operating
- sensor must be reprogrammed
(service)
- fault signal also appears during
programming
E040 Hardware failure, electronics
defective
E113 Hardware failure
Adjustment steps
On the following pages, you will find the com-
plete menu schematic of the adjustment mod-
ule MINICOM.
Set up the sensor in the numbered se-
quence:
1. Address
2. Measurement in gases
3. Operating range
4. Adjustment
5. Conditioning
6. Meas. conditions
7. False echo storage (only required if errors
occur during operation).
8. Indication of the useful level and noise level
9. Outputs
Below you will find short explanations to
setup steps 1 … 9.
1. Address
Choose a free bus address with the DIP
switch (see chapter "4.2 Sensor address").
2. Measurement in gases
Adjustment is only necessary if the measure-
ment is made in gases other than air (CO
2
,
He, etc.). When measuring in gases, sound
the distance from the sensor to the product
surface and enter this in the menu item
"
Measurement in gases". The sensor can then
take the altered (compared to air) sonic ve-
locity into account and output correct levels.
