1.3 Device description
This device is a 2-wire level transmitter that uses FMCW (Frequency Modulated Continuous
Wave) / Radar technology. Radar is a non-contact technology. It measures the distance, level,
mass, volume, flow rate and reflection of liquids, pastes and slurries .It is particularly suitable
for the level measurement of corrosive and viscous products.
Measurements are given through a 4...20 mA current output and can be displayed via a DTM
(device type manager) for remote communication or an integrated display screen with wizarddriven set-up and online help functions. Only the 4...20 mA current output is used as the safety
function.
INFORMATION!
The manufacturer designed and developed the device for safety integrity level (SIL) 2.
Data for the SIL approval is not taken from field experience (i.e. it is not
this method can give unrealistic data if assumptions are too optimistic.
When the device detects a measurement error, it supplies an output current less than 3.6 mA.
Although the device can be set to a high error value (≥ 21 mA), some hardware failures can cause
the device to give a low error value (≤ 3.6 mA). For more data, refer to

WARNING!
The data in this supplement only contains the data applicable to the SIL approval. The technical
data for the standard version in the handbook (document [N1]) shall be valid in its current
version, provided that it is not rendered invalid or replaced by this supplement.
6.2 Safety function definition
6.2.1 General notes
The device contains a safety function that agrees with the standard (document [N2]). This safety
function operates if there is a large difference between the level measurement and the level
shown as a current output.
If the device senses that there is a difference of more than 2.5% between the level measurement
and the level shown as a current output, then the current output changes to an error signal
(≤ 3.6 mA) in less than 30 seconds. The safety integrity level of this safety function is SIL2.
SPECIFICATION OF SAFETY FUNCTION 6
INFORMATION!
If menu item 2.4.5 ERROR DELAY = 0 s, then the current output changes to an error signal
(≤ 3.6 mA) in less than 10 seconds. If menu item 2.4.5 ERROR DELAY is more than 0 seconds,
then the current output changes to an error signal (≤ 3.6 mA) in 10 seconds + 2.4.5 ERROR
DELAY.
6.2.2 Limits of application
This version of the device has the restrictions that follow:
• Distance is measured in Direct mode
• Only the compact version (the signal converter is attached directly to the antenna) can be
used.
• It is a 2-wire loop-powered device.
• Use DN80 and DN100 Metallic Horn antenna only in stilling wells as specified in the handbook
(document [N1]).

6 SPECIFICATION OF SAFETY FUNCTION
6.2.3 Safety function characteristics
The safety function uses only a 4...20 mA analog output signal to measure the level and give the
device status. The analog output signal has an accuracy of ±2.5%.
WARNING!
The device must have the applicable options and settings for the application. The ambient and
process conditions must agree with the technical data given in the handbook (document [N1])
and this document (safety manual). You must obey the installation instructions given in the
