Important: transducers using four-wire connection
If connecting a transducer with 4-wire cable, you must link the
sensor circuit to the appropriate bridge excitation circuit in the
transducer connector (sensor circuit (-) to bridge excitation
voltage (-) and sensor circuit (+) to bridge excitation voltage (+).
A cable must only ever be extended using six-wire connection.
