3 MVX Operating
3.1 Principle
Unlike most predictive maintenance system on the market, ONEPROD MVX
performs sequences of simultaneous acquisitions on all measurement channels.
These acquisitions are really synchronous and in phase.
3.2 Operating conditions
Signal acquisitions can be performed (depending on the configuration) under specific
operating conditions for the machine(s) under monitoring.
These operating conditions can be:
A rotation speed, acquired by MVX through a “trigger input”-type frequency
signal connected to one of the analogue inputs.
Values of one or two process parameters (power, temperature, etc.) acquired
by MVX one of the analogue inputs through a continuous voltage or 4-20 mA
current signal.
Up two 3 logical data (TTL signal) acquired by MVX on its logical inputs.
3.3 Operating in “Monitoring” mode
When MVX is set up to perform monitoring operations, the processing of data
acquired simultaneously aims at calculating indicators and comparing them to alarm
thresholds.
This calculation is performed:
During acquisition for the real time indicators (MVX Premium only)
After each acquisition phase for the standard indicators.
Thus, MVX alternates acquisition and processing phases and a set of updated
“results” indicators is available after each processing phase.
