3500/22M Transient Data Interface Module

　　Description

　　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).

　　I/O Module Signal Common Terminal

　　Both versions of the TDI I/O Module now include a 2-pin connector for connecting Signal Common to a single point Instrument Ground for the rack. When this is done, the selector switch on the side of the Power Input Module (PIM) must be slid in the direction of the arrow marked "HP" to isolate Signal Common from chassis (safety) ground.

　　Data Collection

　　Keyphasor Inputs

　　Supports the four 3500 system Keyphasor signals. The speed range support is based on the number of dynamic channels enabled:

　　Supports multiple events per revolution speed inputs up to 20 kHz

　　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

　　Alarm Data Collection

　　Pre- and post-alarm data

　　Static values collected at one second intervals for 10 minutes before the event and 1 minute after the event

　　Static values collected at 100 ms intervals for 20 seconds before the event and 10 seconds after the event

　　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

　　Static Values Data

　　TDI will collect the static values including the values measured by the monitors.

　　TDI provides four nX static values for each point. Amplitude and phase are returned for each of the values.

　　Waveform Sampling

　　Collection of waveforms for 48 channels.

　　DC-coupled waveforms

　　Simultaneous Synchronous and Asynchronous data sampled during all operational modes

　　User-configurable Synchronous

　　waveform sampling rates:

　　1024 samples/rev for 2 revolutions

　　720 samples/rev for 2 revolutions

　　512 samples/rev for 4 revolutions

　　360 samples/rev for 4 revolutions

　　256 samples/rev for 8 revolutions

　　128 samples/rev for 16 revolutions

　　64 samples/rev for 32 revolutions

　　32 samples/rev for 64 revolutions

　　16 samples/rev for 128 revolutions

　　Asynchronous data sampled to support an 800-line spectrum at the following frequency spans:

　　10 Hz

　　20 Hz

　　50 Hz

　　100 Hz

　　200 Hz

　　500 Hz

　　1000 Hz

　　2000 Hz

　　5000 Hz

　　10 kHz

　　20 kHz

　　30 kHz

　　Asynchronous data is anti-alias filtered

　　Channel Pairs for providing Orbit or synchronous full spectrum presentations can be split among multiple monitors. For asynchronous full spectrums the channels must be within a monitor channel pair (30 kHz frequency span data will not be phase correlated between channel pairs)

　　The 3500/22M has a MT-RJ Male connector on the unit for Fiber Optic 100 Base-FX cabling therefore you MUST use a MT-RJ Female connector on the fiber optic cable to ensure proper connectivity.
