IMx-M General Overview

SKF Multilog On-Line System IMx-M
User Manual
The design ensures that a single circuit failure cannot affect more than two
measurement channels and it is possible to detect and indicate the circuit failure.
The system makes it possible to have selected channels configured for redundancy.
All channels are designed to prevent any one channel from affecting any other
channel.
Condition Monitoring Module (CMM) Buffer Storage Capacity
Each condition monitoring module has 8 MB flash memory used for the following.
–
2 MB for firmware, configuration files, etc.
–
2 MB for trend value buffer
o
About 13 000 vibration trend values can be buffered
o
Speed and process data use half the space of vibration
–
4 MB for spectra and time signal buffer
o
About 250 spectra using 1 600 lines with phase and time signal can be
buffered
o
If more lines are used, the number of spectra is reduced.
o
If less lines are used, the number of spectra is increased
–
When the buffer gets full, the oldest data is thrown away.
Initiating an IMx-M
The machine protection configuration is done through the application tool called
and a (portable) computer using the USB interface located on
protection modules or via @ptitude Observer over an Ethernet connection.
The condition monitoring configuration is done through @ptitude Observer
software.
parameters, such as IP address, IMx identification
number, etc. are done through the application tool called IMx-M Manager. The
parameters are stored first in a separate configuration file, then transferred to the
IMx-M memory.
The configuration is retained in the event of power losses, so that the IMx-M can
start automatically when power returns.
