2.5.6

MULT.REF.EN.

Multiple reflections will cause the

device to display smaller level

readings. Objects in the tank, sharp

corners, installation of the device

on a large nozzle or at the centre of

a dome roof, and low dielectric

products (ε

= 1.8...5) can cause

multiple reflections. A very calm

surface or a tank with a small

convex or flat roof can also cause

multiple reflections.

If this function is in operation, the

device looks for the first signal

peak below the process

connection. This signal peak is then

used to measure the level of the

tank contents. If this function is not

in operation, the device looks for

the largest signal below the

process connection.

YES, NO

2.5.7

EMP.SPEC.EN.

The supervisor can start or stop the

empty spectrum filter.

YES, NO

2.5.9

HART ADDRESS

Any HART

address more than 0

will activate HART

multidrop

mode.

Multidrop mode is not permitted

for SIL-approved devices.

min-max:

0…63

Do not change.

2.8.1

INPUT TAB.

The device uses the conversion

table to convert distance or level

measurements to volume and

mass readings. The readings are

shown in normal mode.

min-max:

0…30 conversion

pairs

1 Use only "4-20 / 3.6E" or "3.8-20.5 / 3.6E"
2 Units and range depend on the output function, length unit and volume unit selected
3 If the safety function must immediately give a result, we recommend that you do not change this value
4 This menu item does a continuous check for radar reflections between the blocking distance (value set in menu item

2.3.2) and the flange. But condensation or other sources of parastic signals can cause an "overfill" error. If you set this
menu item to "YES", make sure that there are no sources of parasitic signals near to the flange.

No.
