Voltage sensors: voltage limits
The user can set the range of valid measurement values by set a maximum voltage.
If the measurement values are over the maximum value a diagnosis is set.
The allowable maximum voltage values range from 10,05 V to 11,5 V.
The following table summarize MA2/MA4 module behaviour as a function of
measurement values.
(A) < Minimum voltage limit
(A) > Maximum voltage limit
Minimum voltage limit < (A) < Maximum voltage limit
Sensor anomaly: measure saturated at 0 mA or 25 mA
This option let the user to choose which value MA2/MA4 will force to the
measurement when a sensor anomaly is detected.
The list of sensor anomalies are reported below:
Disconnected cable (only for 4mA/20mA sensors)
Isolated channel power supply overload
Isolated channel input overload
Analog Output
When this flag is checked the raw value of the measurements are available to MSD.
This is highlighted on input block by a light green square .
