envea ProSens - 7 Fitting up to 3 Sensors

7. Fitting up to 3 sensors
As an option up to 3 sensors can be connected to the Evaluation unit (eld housing or DIN Rail) via
the C3-Box to allow large pipe cross-sections to be monitored better.
The sensor addresses and the registration of the sensors on the Evaluation unit is completed at the
factory and cannot be changed by the user.
The conguration is identical to the conguration of a single system:
The raw value is formed as the arithmetic mean of the raw values of the individual sensors.
The raw values of all the sensors can be viewed in the online display.
The error monitoring is extended to all registered sensors.
•
If one sensor is missing this will cause a sensor error
•
The occurrence of an internal error in a sensor will cause a sensor error
•
A sensor error will be signalled as follows:
•
Field housing: "Sensor error" will be shown on the display
•
DIN Rail: the RUN LED will ash quickly
•
Both: reduction in current output to the alarm value
