Operating instructions
Note!
These operating instructions describe the installation of an SKF LRM2
Lubrication Remote Monitor on SKF lubrication pumps approved for this application.
Fault signals, fill level control, and interim lubrication can be remotely monitored,
depending on the pump design. Programming is performed using an SKF Monitoring
app installed in the LRM2 on which the pump parameters file (**.db) is loaded.
The additional description of the SKF Monitoring app (951-181-020-EN) provides
information on programming deviating functionality.
The operating instructions for UMTS/HSPA Fault Indicators (951-181-021-EN)
describes all programming options for the LRM2 in detail.
The SKF Monitoring app, SKF LRM2 user manual, and other SKF documents on
programming are stored on the supplied LRM2 USB stick.
