Description
The Rack Interface Module (RIM) is the primary interface to the 3500 rack. It
supports a proprietary protocol used to configure the rack and retrieve
machinery information. The RIM must be located in slot 1 of the rack (next to the
power supplies).
The RIM supports compatible Bently Nevada external communications
processors such as TDXnet, TDIX, and DDIX. While the RIM provides certain
functions common to the entire rack, the RIM is not part of the critical monitoring
path and has no effect on the proper, normal operation of the overall monitoring
system. One RIM is required per rack.
For Triple Modular Redundant (TMR) applications, the 3500 System requires a
TMR version of the RIM. In addition to all the standard RIM functions, the TMR RIM
also performs “monitor channel comparison.” The 3500 TMR configuration
implements monitor voting using the setup specified in the monitor options.
Using this method, the TMR RIM continually compares the outputs from three (3)
redundant monitors. If the TMR RIM detects that the information from one of
those monitors is no longer within a configured percentof the information of the
other two monitors, it will flag that the monitor is in error and place an event in
the System Event List.

Configuration
Keylock
Used to place 3500 rack in either
“RUN” mode or “PROGRAM” mode.
RUN mode allows for normal
operation of the rack and locks
out configuration changes.
PROGRAM mode allows for
normal operation of the rack and
also allows for local or remote
rack configuration. The key can
be removed from rack in either
position, allowing switch to
remain in either RUN or PROGRAM
positions. Locking switch in the
RUN position allows you to restrict
unauthorized rack
reconfiguration. Locking switch in
PROGRAM position allows remote
configuration of a rack at any
time.
