1.1 Scope of the document
This document supplies functional safety data about the device. This data agrees with the
IEC 61508 standard.
1.2 Revision history
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.
INFORMATION!
Installation, commissioning and maintenance may only be carried out by approved personnel.

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 wizard-
driven set-up and online help functions. Only the 4...20 mA current output is used as the safety
function.
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
Limits for supervisor
menu functions related to device configuration
on page 23 (2.4.2 RANGE I).
Refer also to "Device description" in the handbook (document [N1]).
1.4 Related documentation
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
“ proven in use ” ) because
this method can give unrealistic data if assumptions are too optimistic.
