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.

hen accessing the display window

take the following m
easures to minim
ize the risk of explosion from electrostatic discharges, in
addition to avoiding any actions that cause the generation of electrostatic charges, such as rubbing w
ith a dry cloth.
To avoid electrostatic charge on the operator, -
Earth the operator through a wrist-strap, or
-O
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
osphere around FLXA21 before the operation.
