Terminal assignment
The terminal assignment in the SPU terminal box (see
pg. 43, Figure 14) is the same as for
the installation of the FLOWSIC600 in non-hazardous areas (see table
pg. 44, 3.4.5).
The connections of the ultrasonic transducers are intrinsically safe and are safely
separated from one another and from other non-intrinsically safe circuits. The transducers
may be connected and disconnected during operation as long as the safe separation of
circuits has been preserved in every respect. In order to ensure this, the respective
transducer connection cable should be disconnected at both ends (disconnect the
electronics side first, and then if necessary, the transducer side unless the MCX connector
is suitably fixed to prevent any uncontrolled movement). Operation using sensors or cables
not part of the original delivery or with sensors/components from other manufacturers is
not permitted.
