Description:
The MPC4 machinery protection card is the central
element in the VM600 series machinery protection
system (MPS), from Meggitt Sensing Systems’
Vibro-Meter® product line. This very versatile card is
capable of measuring and monitoring up to four
dynamic signal inputs and up to two speed inputs
simultaneously.
The dynamic signal inputs are fully programmable
and can accept signals representing acceleration,
velocity and displacement (proximity), among others.
On-board multi-channel processing allows
measurement of various physical parameters,
including relative and absolute vibration, Smax,
eccentricity, thrust position, absolute and differential
housing expansion, displacement and dynamic
pressure.
Digital processing includes digital filtering, integration
or differentiation (if required), rectification (RMS,
mean value, true peak or true peak-to-peak), order
tracking (amplitude and phase) and measurement of
the transducer-target gap.
The speed (tachometer) inputs accept signals from a
variety of speed sensors, including systems based on
proximity probes, magnetic pulse pick-up sensors or
providing TTL signals. Fractional tacho ratios are also
supported.
The calibration may be expressed in metric or
imperial units. Alert and Danger set points are fully
programmable, as are alarm time delay, hysteresis
and latching. The Alert and Danger levels can be
adapted as a function of the speed or any external
information.
A digital output is available internally (on the
corresponding IOC4T card) for each alarm level.
These alarm signals may be routed on a bus within
the VM600 rack to drive relays on optional relay cards
(such as the IRC4 and RLC16).
The processed dynamic (vibration) signals and speed
signals are available at the rear of the rack (on the
front panel of the IOC4T) as analog output signals.
Voltage-based (0 to 10 V) and current-based
(4 to 20 mA) signals are provided.
The MPC4 performs a self-test and diagnostic routine
on power-up. In addition, the card’s built-in
“OK System” continuously monitors the level of
signals provided by the sensors and indicates any
problem due to a broken transmission line, faulty
transducer or conditioner.
An LED indicator on the MPC4 front panel indicates
whether a processing or hardware error has occurred.
Six additional LEDs (one per input channel) indicate
whether the OK System has detected a fault and
whether an alarm has occurred on the channel
