Bently 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 Diagnostics Software and 3500 System Configuration Software).

(System 1 Condition Monitoring and Diagnostics Software and 3500 System Configuration Software).

The TDI combines the functionality of the 3500/20 Rack Interface Module (RIM) with the data collection capabilities of a communications processor such as TDXnet.

The TDI is located in a slot next to the 3500 rack power supply. It interfaces with M-Series monitors (3500/40M, 3500/42M, etc.).

It connects to the M-Series monitors (3500/40M, 3500/42M, etc.) and continuously collects steady-state and transient dynamic (waveform) data and transmits this data to the host software via an Ethernet link.

See the Compatibility section at the end of this document for more information.

The static data collection feature is standard on the TDI.

However, using the optional Channel Enable Disk, the TDI can also capture dynamic and high resolution transient data.

TDI integrates communications processor functionality within the 3500 rack.

While the TDI provides some common functionality throughout the rack, it is not part of the critical monitoring path.

It has no impact on the proper functioning of the entire monitoring system for automatic machinery protection.

One TDI or RIM is required per 3500 rack and always occupies slot 1 (next to the power supply).

I/O Module Signal Common Terminal

Both versions of the TDI I/O Module now have a 2-pin connector to connect the signal common to the rack's single point instrument ground.

The rack's single point meter ground. When connecting, the selector switch on the Power Input Module (PIM) side must be slid in the direction of the arrow marked "HP".

Slide in the direction of the arrow marked "HP" to isolate the signal common from the chassis (safety) ground.

Keypad Signal Inputs

Four 3500 system key signals are supported. The range of speeds supported depends on the number of dynamic channels enabled:

l Supports velocity inputs with multiple events per revolution up to 20 kHz

Startup/Shutdown Data

Data collection at selected speed and time increments

Increasing and decreasing speed intervals are independently programmable

Transient data collection is initiated by detecting machine speed within one of two programmable windows

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

Alarm data collection

Pre- and post-alarm data

Within 10 minutes and 1 second prior to the event

10 minutes before and 1 minute after event

1 minute after event

Static values collected at 100 ms intervals

20 seconds before and 10 seconds after the event

Static value 10 seconds after event

Waveform data collected at 10-second intervals for 2.5 minutes before an alarm occurs

Collect waveform data for 2.5 minutes at 10 second intervals

and 1-minute waveform data

1-minute waveform data at 10-second intervals after an alarm

Static Value Data

The TDI will collect static values, including

monitor measurements.

The TDI provides four nX static values for each point.
