Function

Input Range

Description

1.5.0 Application

For difficult applications

Enter a value 0 mm /
0 in. to Fct. 1.1.2
Dead zone

1.5.1 Detection delay

As per order

This function can be used to define
an area directly below the flange in
which interference reflections (e.g.
from the tank nozzle) are masked.
This value has to be smaller than or
equal to the dead zone (Fct. 1.1.2.).

1.6.0 Serial I/O
(serial input/output)

For integrating into a signal
network. Standard hardware
platform for HART

®

is the current

loop with superposed FSK signals.
For a multidrop application the
current output is set to “OFF” and
consequently to a constant 4 mA.
With a multidrop bus, up to 15
HART

®

devices can be operated.

Addresses from
0 to 15

1.6.2 Address

0

With this function, every device
connected to a bus is assigned an
address between 0 and 15 (HART

®

protocol). If several devices are
connected to a digital bus, each
device must be assigned a unique
address under which it can then be
identified in the bus.
0 = Analogue output active
1 - 15 = Multi-drop mode active,

analogue output inactive

1.7.0 Volume

table

For calibrating the gauge for
volume measurement.

Select point 01 to 20,
enter level and then
volume values
respectively.

1.7.2. Input table

0
(conversion table
not created, volume
measurement not
possible)

This function is used for setting up
the strapping table (level/volume). Up
to 20 points can be assigned. Every
new point must be larger than the
preceding one. The units of length
and volume can be changed later
without affecting the settings in the
table.
The units selected for length and
volume in fct.s 1.2.4 and 1.2.5 will be
used here.
