Sensors measure and transmit all variations encountered at their location. Measurement is taken based on design features (time constant) and according to specific operating conditions.With wiring run in raceways, the sheath (or pipe) containing the wires must be plugged at the sensor's terminal board so that currents of air cannot affect the sensor's measurements.

  • Page 107: Automatic Mode

    M12927CA OPERATIVE MODES When the instrument is powered, it starts immediately to work according to the parameters values loaded in its memory. The instrument behaviour and its performance are governed by the value of the stored parameters. At power ON the instrument can start in one of the following mode depending on its configuration: Automatic Mode In Automatic mode the instrument drives automatically the control output according to the parameter value set and the set point/measured value.
