    FAQs

    Q1: What is the primary function of the 3500/20-01-01-00?

    It is the primary communication interface for the 3500 rack. It supports Bently Nevada's proprietary protocol used to configure the rack and retrieve machinery information. It enables connection to host software such as System 1 for configuration, data acquisition, and diagnostic purposes.

    Q2: Can the 3500/20-01-01-00 be installed in any slot?

    No. It must be installed in Slot 1, adjacent to the power supply. Each 3500 rack requires exactly one RIM or TDI. The module provides certain common functions for the entire rack but is not part of the critical monitoring path.

    Q3: What is the difference between 125744-02 and 135031-01?

    The 125744-02 is the Standard Rack Interface Module (main card) that performs communication and data management functions. The 135031-01 is the RIM I/O Module with built-in modem interface that provides the physical modem connection for remote communication. Both are required together to form a complete RIM with modem capability.

    Q4: Does the RIM affect the critical monitoring path?

    No. While the RIM provides certain common functions for the entire rack, it is not part of the critical monitoring path. The monitoring system's automatic machinery protection functions continue to operate normally even if the RIM is removed or fails.

    Q5: What is the TMR version of the RIM used for?

    The TMR RIM (Option -02 in the A field) is required for Triple Modular Redundant (TMR) applications. In addition to standard RIM functions, it performs monitor channel comparison — continuously comparing outputs from three redundant monitors and flagging any monitor whose output differs from the other two beyond a configured percentage.
