Bently Nevada Machinery Condition Monitoring

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).

Indicates when the 3500 rack is
operating normally or when a
fault has been detected within
the rack. User can select either an
“OPEN” or “CLOSED” contact to
annunciate a NOT OK condition.
This relay always operates as
“Normally Energized”.

Used to set the rack address:
127 possible addresses

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.

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.

l Supports multiple events per revolution

speed inputs up to 20 kHz

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
