BENTLY 3500/22M Used in the monitoring system

The 3500/22M Transient Data Interface (TDI) is the interface between the 3500 monitoring system and compatible software (System 1 Condition Monitoring and Diagnostic software and 3500 System Configuration software). The TDI combines the function of a 3500/20 Rack Interface Module (RIM) with the data collection capability of a communication processor such as TDXnet. The TDI resides in the slot adjacent to the power supplies of a 3500 rack. It interfaces with M series monitors (3500/40M, 3500/42M, etc.) to continuously collect steady state and transient dynamic (waveform) data and pass this data through an Ethernet link to the host software. Refer to the Compatibility section at the end of this document for more information. Static data capture capability is standard with the TDI. However, using an optional Channel Enabling Disk will allow the TDI to capture dynamic and high-resolution transient data as well. The TDI incorporates the communication processor function within the 3500 rack. Although the TDI provides certain functions common to the entire rack, it is not part of the critical monitoring path and has no effect on the proper, normal operation of the overall monitor system for automatic machinery protection. Every 3500 rack requires one TDI or RIM, which always occupies Slot 1 (next to the power supplies).

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 the rack in either position, allowing the switch to remain in either the RUN or PROGRAM position. Locking the switch in the RUN position allows you to restrict unauthorized rack reconfiguration. Locking the switch in PROGRAM position allows remote reconfiguration of a rack at any time.

Startup/Coastdown Data 

Data collected at selected increments of speed and time

Increasing and decreasing speed intervals are independently programmable 

Initiation of transient data collection based on detecting the machine speed within one of two programmable windows 

The number of transient events that can be collected is only limited by the available memory in the module
