Can please anybody tell me what is the function of the system monitor (3300/03) installed on the second rack after power supply of Bently Nevada Vibration Monitoring Unit? The function in the manual is not quite clear to me. Thanks Guys!

 

You haven't stated which type you have there since most 3500 series come as a single rack. I would guess you have a 3500 first rack with a 3300 2nd rack, with the system monitor interfacing the two.

 

Did you mean the second rack position? That is the normal position of the System Monitor 3300/03 next to the power supply. It's functions are digital communications, monitors overall operations of other modules in the rack, monitors voltage supply levels, adjustment of alarm set points of other monitors, and various other indications and operations.
