Model FLXA212-Wire AnalyzerPROFIBUS PA Communication

GS 12A01A02-72E

n GeneralPROFIBUS is a vendor-independent and open fieldbus based on the international standard IEC61158 and IEC61784. It covers a wide range of applications in manufacturing and process automation fields.Vendor-independence and openness allow communication between devices of different manufactures with no special interface adjustment.FLXATM21 PROFIBUS PA model offers more flexible instrumentation through a higher level communication capability and proposes the cost reduction by multidrop wirings with fewer cables.

In the FLXA21 Human Machine Interface (HMI), 2-wire type analyzer FLXA21 offers easy touch screen operation and simple menu structure in 12 languages. Menus of display, execution and setting are displayed in a selected language.The analyzer FLXA21 automatically recognizes the installed sensor module and prepares the necessary menus for right configuration.For immediate measurement, the FLXA21 offers quick setup functionality. The quick setup screen appears when the analyzer is powered. Only a few setups – date/time, language, basic sensor configurations and output – will start the measurement.

The FLXA21 offers the best accuracy in measurement with temperature compensation functionality and calibration functionality. Sensor diagnostics and sensor wellness indication make measurement reliable. Logbook of events and diagnostic data is a useful information source for maintenance.

To avoid electrostatic charge on the operator, -

Earth the operator through a wrist-strap, or

perate FLXA21 on the conductive floors, wearing anti-static w

ork clothes and electrostatic safety shoes, or

-N

eutralize the operator and FLXA21 by a static elimination bar w

hich has a metal part

earthed through resistor from 100k

to 100M.

In case that those measures cannot be taken or static electricity cannot be suppressed, bring a

gas detector and make sure there is no ignition capable atm

(Class D ground: 100 ohm or less) Connect the grounding cable to the terminal of the power module inside. Use a cable with an outside diameter of 3.4 to 7 mm for the grounding line of the plastic housing. The minimum cross sectional area of the protective grounding cable should be 0.75 mm2.*3: Terminal numbers for each sensor module are shown below.*4: The terminal box may be necessary depending on the sensor cable length and the distance between the
