Diagnostic
Isolated sensor power supply
overload (if the sensor draws more
than 30 mA)
YES with active protection.
When this condition is detected the power supply of the sensor is disconnected for
1 second and then again activated to check if the overload condition still exist in
an endless loop until the overload condition disappear.
Input overvoltage / input
overcurrent
YES with active protection.
When this condition is detected the power supply of the sensor is disconnected for
1 second and then again activated to check if the input overvoltage/overcurrent
condition still exist in an endless loop until the anomaly disappear.
Disconnected cable detection
YES
Overthreshold / Underthreshold
detection
YES
Connection to M1S
via MSC 5-way ReeR proprietary bus
