Introduction
IMx-M General Overview
SKF Multilog On-Line System IMx-M
1 - 7
User Manual
–
All relays are placed upon relay modules except for circuit fault and disarmed
relays which are placed upon protection module.
–
All relays upon relay modules are user configurable.
Condition monitoring module and protection module pair ("CMM + PRM" or "CMM +
PRM slot")
–
Up to four pairs of a condition monitoring module and a protection module
–
Analog channels
o
Each CMM + PRM slot has 16 analog signal inputs
o
Up to 64 analog signal inputs in total when having four CMM + PRM slots
o
The dynamic signal inputs are configurable for a wide variety of sensors.
Signals, such as acceleration, velocity and displacement or other
parameters are easily adopted. Each input can also be configured for
standard accelerometers, 4
–
20 mA or ±23 V.
o
Several measurement points may be attached to one channel and both AC
and DC measurements can be measured on the same channel
–
Digital channels
o
Each CMM + PRM slot has eight digital channels
o
Up to 32 digital channels in total when having four CMM + PRM slots
o
Digital channels are available for measuring speed, trigger or digital status;
for example, indicating when a measurement can take place
IMx-M System Main Parts
Machine protection
part
for the safety related functions which consists of
protection modules and relay modules.
Condition monitoring
part
for early fault detection (non-safety related functions)
which consists of condition monitoring modules.
Power supply units are a common part for both machine protection and condition
monitoring.
IMx-M's Unique Features
Individual conditions for alert and danger may be set for each measurement point.
Each channel has indicators for alert and danger. However, it is also possible to
manually bypass the alert and danger functionality.
The rack is offering remote reset of latching alert/danger conditions.
All channels are fully computed in parallel, both condition monitoring and machine
protection.
The built-in hardware auto-diagnosis system continuously checks all sensors,
cabling and electronics for any faults, signal interruption, short circuits or power
failure.
