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]).

OPTIWAVE 5200 C
www.krohne.com02/2013 - 4001906202 - AD SIL OPTIWAVE 5200 R02 en
6.1 Preliminary requirements
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.
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.
•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
(≤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.

OPTIWAVE 5200 C
www.krohne.com 02/2013 - 4001906202 - AD SIL OPTIWAVE 5200 R02 en
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%.
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.
For more data about the top dead zone, refer to the "Operation" and "Technical Data" chapters in
the handbook (document [N1]).

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

1.5...1.7), use "TBF Partial" mode.
"TBF Partial" is an automatic mode
that lets the device make a
selection between "Direct mode
and "TBF" mode. If you use "TBF
Full" or "TBF Partial", enter the

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.

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 (εr= 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 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.

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 neccessary 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.
