5 Safety function
5.1 Definition of the safety function
The measuring device's permitted safety functions are:
• Monitoring of a maximum or minimum mass flow or a mass flow range for liquid or
gaseous media
• Monitoring of a maximum or minimum volume flow or a volume flow range for liquid
media
The safety functions are based on the simultaneous, continuous measurement of the mass
flow and the density of a liquid.
• Monitoring of a maximum or minimum density or a density range for liquid media
5.1.1 Safety-related output signal
The measuring device's safety-related signal is the 4–20 mA analog output signal (output;
input 1). All safety measures refer to this signal exclusively.
In devices with several outputs, only current output 1 (terminals 26 and 27) is suitable for
safety functions. The other outputs can, if necessary, be connected for non-safety-oriented
purposes.
The safety-related output signal is fed to a downstream automation system where it is
monitored for the following:
• Overshooting and/or undershooting of a specified limit value for the flow or the density of
the medium
• The occurrence of a fault: e.g. failure current (≤ 3.6 mA, ≥ 21 mA), interruption or short-
circuit of the signal line
The safety-related errors are broken down in accordance with IEC/EN 61508 into different
categories and implications for the safety-related output signal.

5.2.3 Suitability of the measuring device
1. Carefully select the nominal diameter of the measuring device in accordance with the
application's expected flow rates.
 The maximum flow rate during operation must not exceed the specified maximum
value for the sensor.
2. In safety-related applications, it is advisable to select a limit value for monitoring the
minimum flow that is not less than 5 % of the specified maximum value of the sensor.

LCAUTION
Pay particular attention to the following:
‣It is the responsibility of the user to assess the influence of the process conditions and the
medium on the measurement result in safety equipment, particularly the occurrence of
two-phase mixtures, buildup, abrasion and corrosion, for example.
‣In the case of liquids with a low boiling point or liquids in suction lines, it is important to
ensure that the vapor pressure is not undershot and that the liquid does not start to boil.
‣Please ensure that there is never any outgassing of the gases naturally contained in many
liquids. Sufficiently high system pressure prevents the occurrence of these effects.
‣Make sure that cavitation does not occur as it can affect the operating life of the measuring
tubes.
‣If gaseous media are used, turbulences can occur at high flow velocity rates, e.g. if valves
are half-closed. This can cause the measured values to fluctuate.
No special measures need to be taken into consideration for single-phase, liquid media with
properties similar to water.
Further information on the suitability of the measuring device for safety-related
operation is available from your Endress+Hauser sales center.
5.2.4 Information on measured errors
When the measured value is transmitted via the 4–20 mA current output, the measuring
device's relative measured error is made up of the contribution of the digitally determined
measured value and the accuracy of the analog current output. These contributions, which are
listed in the device documentation, apply under reference operating conditions and can
depend on the sensor version ordered. If process or ambient conditions are different, there are
additional contributions, e.g. temperature or pressure, which are also listed.
For further information on calculating the measured error, see the Technical
Information. →  11
5.2.5 Power supply to the 4–20 mA current output
Overvoltages at the 4–20 mA current output (passive, output; input 1) - caused by a fault in
the supply unit, for example - can result in a leak current in the device's input protection unit.
This may lead to falsification of the output signal by more than the specified error or the
minimum failure current (3.6 mA) can no longer be set due to the leak current.
‣Use a 4–20 mA power supply unit with either voltage limitation or voltage monitoring.
NOTICE
The safety-related connection values depend on the Ex approval.
‣Pay attention to the safety-related connection values.
For detailed information on the connection values, see the Safety Instructions.→  12
5.2.6 HART communication
The measuring device also communicates via HART or WirelessHART in the SIL mode. This
comprises all the HART features with additional device information.

Proline Promass 500 Use in protective systems
Endress+Hauser 19
NOTICE
The measuring device's safety-related signal is the 4–20 mA analog output signal
(output; input 1).
All safety measures refer to this signal exclusively.
‣Please note the following: →  15.
NOTICE
When the SIL locking code is entered, the device parameters that affect the safety-
related output signal are locked and write-protected. It is still possible to read the
parameters.
When SIL locking is enabled, restrictions apply on all communication options, such as the
service interface (CDI-RJ45), HART protocol and WirelessHART protocol, local display and
WLAN.
‣Deactivation of the SIL mode →  29.
6 Use in protective systems
6.1 Device behavior during operation
6.1.1 Device behavior during power-up
Once switched on, the device runs through a start-up phase. The current output is set to
failure current during this time. This current is ≤ 3.6 mA in the initial seconds of this start-up
phase.
No communication with the device is possible via the interfaces during the start-up phase.
After the start-up phase the device switches to the normal mode (measuring operation).
6.1.2 Behavior of device during operation
The device outputs a current value which corresponds to the measured value to be monitored.
This value must be monitored and processed further in an attached automation system.
6.1.3 Device behavior in safety function demand mode
Depending on the setting of the Failure mode parameter, the current is as follows in demand
mode:
• For Min. option: ≤ 3.6 mA
• For Max. option: ≥ 21 mA
6.1.4 Device behavior in event of alarms and warnings
The output current on alarm can be set to a value ≤ 3.6 mA or ≥ 21 mA.
In some cases (e.g. a cable open circuit or faults in the current output itself, where it is not
possible to set the failure current ≥ 21 mA) output currents of ≤ 3.6 mA occur irrespective of
the configured failure current.
In some other cases (e.g. short circuit of cabling), output currents of ≥ 21 mA occur
irrespective of the configured failure current.

Use in protective systems Proline Promass 500
20 Endress+Hauser
For alarm monitoring, the downstream automation system must be able to recognize both
maximum alarms (≥ 21 mA) and minimum alarms (≤ 3.6 mA).
6.1.5 Alarm and warning messages
Additional information is provided by the alarm and warning messages output in the form of
diagnostic events and associated event texts.
NOTICE
A diagnostic message is displayed even though the diagnostic event is no longer active in
the unlocked SIL mode.
When SIL mode is activated, additional diagnostics are activated. If a diagnostic event is
pending and the locked SIL mode is deactivated, the diagnostic message remains as long as
the error is still present.
‣In this case, the device must be disconnected briefly from the power supply .
‣When the device is then restarted, a self-check is carried out, and the diagnostics event is
reset where applicable.
This behavior occurs in the case of the following diagnostic messages:

6.2 Parameter configuration for safety-related applications
6.2.1 Calibration of the measuring point
The measuring point is calibrated via the operating interfaces. A wizard guides you
systematically through all the submenus and parameters that have to be set for configuring
the measuring device.
For detailed information on the operating options, see the Operating
Instructions.→  11
For detailed information on configuring the measuring device, see the Operating
Instructions and Description of Device Parameters →  11
To activate the SIL mode, the device must run through a confirmation sequence. While
running through this sequence, critical parameters are either set automatically by the device
to standard values or transferred to the local display/operating tool to enable verification of
the setting. On completion of parameter configuration, the SIL mode of the device must be
enabled with a SIL locking code.
