7.5 User parameters
7.5.1 Limits for supervisor menu functions related to probe configuration
INFORMATION!
If you change a parameter set in one or more of the menu items that follow, this will have an
effect on the safety function.
WARNING!
If the device was delivered without a probe, then calibrate the device to make sure that the safety
function operates correctly. For more data, refer to Calibration procedure on page 22
.
CAUTION!
This section gives data on the modification of a small number of parameters in the 2.0.0
SUPERVISOR menu. If it is necessary to change parameters in the 3.0.0 SERVICE menu or the
4.0.0 MASTER menu, contact your supplier.
If you change the values of one or more of the parameters given in the "User parameters"
section, this can have an unwanted effect on the safety function. Do a check of the safety
function after you change a parameter.

Make sure that the 4...20mA measurement range is correctly calibrated.
LEGAL NOTICE!
The manufacturer declines all responsibility for the correct operation of the safety function if
these parameters in the 3.0.0 SERVICE or 4.0.0 MASTER menus are changed by the customer.

2.3.3 PROBE LENGTH Probe length is the distance
from the flange face / thread
stop of the device to the
bottom end of the probe
(including counterweight for
cable versions).
min:
2.3.4 BLOC. DIST. +
3.1.1 COUNTERWEIGHT
max.:
40 m / 131 ft
Default value
agrees with the
customer
order.
2.5.7 MEAS. THRESH. Measurement threshold. If it is
difficult to identify the level
signal (for example: too many
parasite signals), you can
increase the threshold. A
threshold of 1000 is equivalent
to the amplitude of the
measurement pulse. A
threshold of 100 is equivalent
to 10% of the amplitude of the
measurement pulse. For more
data, refer to “Operation” in
the handbook (document
[N1]).
min-max: 0…1000 Default value
depends on the
ε
r
of the liquid
or solids in the
tank and the
probe type.
