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 17 (2.4.2 RANGE I).
Refer also to "Device description" in the handbook (document [N1]).

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.

6 SPECIFICATION OF SAFETY FUNCTION
11
DR5200
www.drexelbrook.com DR5200-LM SIL2 Issue 2
6.1 Preliminary requirements
6.2 Definition of the safety function
6.2.1 General notes
The device contains a safety function that agrees with the international standard IEC 61508
(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 finds that there is a difference of more than 2.5%of the 4...20 mA range between the
level measurement and the level shown as a current output, then the current output changes to
an error signal in less than 30 seconds. The safety integrity level of this safety function is SIL2.
6.2.2 Limits of application
This version of the device has the restrictions that follow:
•Distance is measured in Direct mode
Direct modeDirect mode
Direct mode (only one product in the tank is permitted).
•Only the compact version (the signal converter is attached directly to the antenna) can be
used.
•It is a 2-wire loop-powered device.
•HART®communication is not permitted when you use the safety function.
•The process safety time must be more than 33 minutes. This minimum time agrees with
International Standard IEC 61508 Part 2 (document [N2]), section 7.4.4.1.4.
•Use DN80 and DN100 Metallic Horn antenna only in stilling wells as specified in the handbook
(document [N1]).
For more data, refer to
SIL-specific technical data on page 29.
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!
If menu item 2.4.5 ERROR DELAY = 0 s, then the current output changes to an error signal in less
than 30 seconds. If menu item 2.4.5 ERROR DELAY is more than 0 seconds, then the current
output changes to an error signal in 30 seconds + 2.4.5 ERROR DELAY.
After the device finds an error, it will try to measure the level of the product again. If the device
can measure the level, the error signal will change to the measurement signal. If the device
continues to have the same problem, the output current will change to the error signal. If, after
30 seconds, the output current is not 3.6 mA then the error is recorded as a "dangerous
undetected failure" in the FMEDA analysis. If, after 30 seconds, the output current is 3.6 mA then
the error is recorded as a "dangerous detected failure" in the FMEDA analysis.

SPECIFICATION OF SAFETY FUNCTION 6
12
DR5200
www.drexelbrook.comDR5200-LM SIL2 Issue 2
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% of the 4...20 mA range.
For more data about the top dead zone, refer to the"Operation" and "Technical Data" chapters in
the handbook (document [N1]).
If the device finds a fault:
If a logic solver is used, it must use low error alarm signals (current input ≤3.6 mA) to set itself
to a fail-safe condition.
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
handbook (document [N1]).
CAUTION!
We recommend that the 4 and 20 mA limits of the measuring range are not in the top dead zone
(100 mm / 3.9
¨ below the antenna).
The shape of the tank bottom can have a large effect on the accuracy when the tank is almost
empty. We recommend that device is not used to measure the liquid when it is less than 300 mm
from the bottom of the tank.

7.1 Conditions of use
The configuration is protected with a password. For more data on password protection and
device configuration, refer to the “Operation”chapter in the handbook (document [N1]).
7.2 Failure state
For any type of safe or dangerous detected failure, the device sets the current output to less than
3.6 mA. Although this value can also be set to a high error value (≥21 mA), some hardware
failures will always cause the device to give a low error value (≤3.6 mA). Thus, the output signal
for the fail-safe condition is less than 3.6 mA. For more data, refer to
Limits for supervisor menu
functions related to device configuration
on page 17 (2.4.2 RANGE I).
WARNING!
Only approved personnel can change device settings. Keep a report of changes to the device
settings. These reports must include the date, the menu item (e.g. 2.3.1 TANK HEIGHT), the old

2.5.4 MEASUR.MODE The device uses the dielectric
constant (ε
r
) of the tank
contents to monitor level. In
direct mode (if the dielectric
constant is high), the level
signal is a reflection on the
surface of the tank contents.
If the dielectric constant is
low, the device uses TBF
mode. The device in TBF
mode uses the radar
reflection on the bottom of
the tank (the signal goes
through the tank contents).
The tank must have a flat
bottom for the device to
operate correctly in TBF
mode. This menu item is set
by default to "Direct" for tank

2.5.5 OVERF. ENAB. If this function is in operation,
the device will monitor the
level even if it is in the
blocking distance. The
reading shown on the display
stays fixed at the blocking
distance if the level is higher
than the blocking distance.
The output will show that the
tank is full. An error is
recorded by default.
If this function is not in
operation, the device looks
for the largest signal between
the process connection and
the tank bottom.
YES, NO NO 4
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
r
=
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.

4This 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 parasitic 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.

8.1 Periodic maintenance
You must obey the maintenance instructions given in the handbook (document [N1]).
8.2 Keep the device clean
For more data, refer to “Service”in the handbook (document [N1]).
8.3 Availability of services
The manufacturer offers a range of services to support the customer after expiration of the
warranty. These include repair, maintenance, technical support and training.
8.4 Proof tests
It is necessary to do proof tests to make sure that the safety function is applicable to the full
measuring range.
•The device settings must be correct. If a parameter is incorrect, the device will not measure
correctly.
•The electronic components must not be defective.
•The software programs (firmware etc.) must operate correctly.
•The antenna must correctly transmit and receive the measurement signal. Parasitic signals
must not have an effect on the performance of the device.
We recommend that you do a proof test immediately after you install and start the device.
Prepare the device for the proof tests. Do a check of the device parameters.
INFORMATION!
For more precise information, please contact your local sales office.
WARNING!
SIS engineers must calculate the interval of proof tests. The minimum time between proof tests
must be less than 5 years, but the interval between proof tests must also agree with the safety
system used on site.
CAUTION!
• Proof tests done by the customer must be equivalent or more difficult than the tests given in
this section.
• Keep a report of each proof test. These reports must include the date, the tests results
(performance of the safety function or faults found), a list of approved personnel who did the
test and the report revision number. These reports must be put into storage and made easily
available. A proof test report form (for copying) is available on page 33
.
•
The location of the device and how it is installed on the tank can have an effect on the
performance. Make sure that you obey the installation instructions given in the handbook.
