3-_ Downwards compatible hardware and/or software change of inputs and outputs:
I Current output
F, P Frequency / pulse output
S Status output
C Control input
LS Limit switch
X all inputs and outputs
4 Downwards compatible changes with new functions.

1.2 Intended use
The mass flowmeters are designed exclusively to directly measure mass flow rates, product density and temperature as well to indirectly measure parameters such as the total volume and concentration of dissolved substances as well as the volume flow rate.
DANGER!
For devices used in hazardous areas, additional safety notes apply; please refer to the Ex documentation.
CAUTION!
For devices used in SIL applications, additional safety notes apply. For detailed information refer to the "Safety manual".
WARNING!
If the device is not used according to the operating conditions (refer to chapter "Technical data"), the intended protection could be affected.
INFORMATION!
This device is a Group 1, Class A device as specified within CISPR11:2009. It is intended for use in industrial environment. There may be potential difficulties in ensuring electromagnetic compatibility in other environments, due to conducted as well as radiated disturbances.

Make sure that there is adequate space to the sides.
•
The device must not be heated by radiated heat (e.g. exposure to the sun) to an electronics housing surface temperature above the maximum permissible ambient temperature. If it is necessary to prevent damage from heat sources, a heat protection (e.g. sun shade) has to be installed.
•
Signal converters installed in control cabinets require adequate cooling, e.g. by fan or heat exchanger.
•
Do not expose the signal converter to intense vibrations. The measuring devices are tested for a vibration level as described in the chapter "Technical data".

There should be no difference in potential between the flow sensor and the housing or protective earth of the signal converter!
• The flow sensor must be properly grounded.
• The grounding cable should not transmit any interference voltages.
• Do not use the grounding cable to connect more than one device to ground.
• The flow sensors are connected to ground by means of a functional grounding conductor FE.
• In hazardous areas, grounding is used at the same time for equipotential bonding. Additional
grounding instructions are provided in the supplementary "Ex documentation", which are only supplied together with hazardous area equipment.
