Important
Transducer connection in a four/three wire
configuration:
When connecting a transducer in a four/three wire
configuration, the sense leads must be connected to the
corresponding bridge excitation circuit (PIN 2'-2 and
Pin 3'-3) by wire bridges, as otherwise a sensor error will
be detected.
TEDS functionality is not available when connecting in a
fourwire configuration.
