In table 3 are pointed out the failures, their effects on the output signal, on the relay output and how to reset
them:
Failure
Supply wire broken
Sensor unconnected
Supply system broken
Broken chip
Pin detachment
Pressure over 150% of the span vs factory
zero @ RT
Preload loss exceeds -30 % of span vs factory
zero @ RT
Overvoltage
Undervoltage
Voltage variations
Program sequence error
Overtemperature on electronics
Primary or front end stage error
Tab. 3 - Failures, effect on electrical outputs and reset
The analog output levels shown refer to sensors with 4-20 mA output and 0.5-10.5V.
For other electrical output levels, in case of alarm the output level is calculated as follows:
Out Alarm Low(mA,V)< Zero value (mA,V) – 2.50 % span (mA,V)
Out Alarm High (mA,V)> F.S. value (mA,V) + 6.25 % span (mA,V)
In the Impact sensors, no hardware feedback have been implemented.
