3 Product Description
3.1 Main functionality
The VCM-3 supports any state-of-the-art condition monitoring method and provides a platform for
customizations and development of future new monitoring methods.
VCM-3 provides early fault detection by using a large variety of descriptors (scalar values).
Fast real time descriptors locked to the machine speed as well as advanced calculations using
statistics and feature extraction from array measurements.
It has a large configurable history buffer which stores descriptor and array data with a high storage
rate. Offline operation can last for several months in case of network outage and supports standalone
operations for investigations at remote sites with no network connection.
Detailed investigation is supported by high resolution, event based, long duration time waveform
recordings (time samples). Ideal for further detailed frequency analysis, and by high storage rate
descriptor or array data from the history buffer as well as direct on-line reading of descriptor values
down to second intervals.
VCM-3 Connects to a large variety of sensor types, accelerometers, displacement sensors, speed
sensors, 4-20 mA type sensors for process values, DC input, buffered output from other devices and
oil debris sensors or other Modbus enabled devices.
VCM-3 imports data via LAN from other data sources such as other VCM-3s, SCADA systems, or
other subsystems related to the machine.
VCM-3 is user configurable both via direct or remote connection, this allows for simple and quick
change of configuration for updates to the monitoring strategy. Therefore the “Standard (Master)
Monitoring Template” can be edited (change of configure parameters) by an editor software
application to create a “Machine Monitoring Template” suitable for the specific machine and
monitoring strategy.
NOTE!
The range of functions is defined by the “Standard (Master) Monitoring Template”.
The “Standard (Master) Monitoring Template” also determines which channel groups
(AC/DC, Speed/DC, 4-20mA, DO and DI) are enabled on the device. If a channel group
is not enabled on the device, please do not connect it.
