3500/22M 146031-01  Transient Data Interface Module

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).

Startup/Coastdown Data
l Data collected at selected increments of speed and time
l Increasing and decreasing speed intervals are independently programmable
l Initiation of transient data collection based on detecting the machine speed
within one of two programmable windows
l The number of transient events that can
be collected is only limited by the available memory in the module
Alarm Data Collection
l Pre- and post-alarm data
l Static values collected at one second intervals for 10 minutes before the event
and 1 minute after the event
l Static values collected at 100 ms intervals for 20 seconds before the event and 10
seconds after the event
l 2.5 minutes of waveform data collected at 10-second intervals before the alarm and
1 minute of waveform data collected at 10-second intervals after the alarm
