Bently Nevada 3500/22M 138607-01 TDI Module

Description

Key Technical Specifications

The OEM ordering information identifies 138607-01 as the standard 3500/22M TDI and lists 146031-01 as the corresponding 10Base-T/100Base-TX I/O module option. The TDI is installed in the rack slot adjacent to the power supplies.

The 3500/22M combines the rack-interface functions associated with the 3500/20 RIM with data-collection functions for steady-state and transient information. Dynamic/high-resolution transient acquisition depends on the applicable configuration rather than being implied solely by the 138607-01 part number.

Product Introduction

The Bently Nevada 3500/22M 138607-01 is the Standard Transient Data Interface module for the 3500 Machinery Protection System. It provides the interface between the 3500 rack and compatible Bently Nevada software, including System 1 and 3500 System Configuration Software, while collecting steady-state and transient data from M-series monitoring modules.

The module occupies the dedicated TDI position next to the rack power supplies and communicates externally through its associated rear I/O module. The standard 10Base-T/100Base-TX copper configuration uses 146031-01; a fiber configuration uses 146032-01.

Installation & Configuration Guide

Stage 1 — Pre-Installation Preparation

Estimated time: 15–20 minutes

1. Confirm the replacement marking is exactly 138607-01.
2. Verify that the rack is a compatible 3500 system and identify the TDI slot adjacent to the power supplies.
3. Record the installed rear I/O module part number, such as 146031-01 or 146032-01.
4. Record the existing firmware/configuration information before replacement.
5. Back up the applicable 3500 rack configuration.
6. Record current System 1 communication settings and network parameters.
7. Apply LOTO where required by the plant procedure.
8. Prepare an ESD strap, appropriate screwdriver, labels, multimeter, and the applicable 3500/22M documentation.

⚠️ Do not assume that replacing the front TDI card also replaces the rear communication I/O module. The 138607-01 and the rear I/O assembly are separate components.

Stage 2 — Removing the Old Module

Estimated time: 10–15 minutes

1. Place the rack in the approved maintenance state.
2. Confirm whether the installed power architecture permits removal without interrupting protection functions.
3. Disconnect the applicable network/configuration connections according to the rack procedure.
4. Release the front-panel retaining hardware.
5. Carefully withdraw the existing TDI module.
6. Inspect the card edge, backplane connector, retaining hardware, and adjacent modules.
7. Record the removed module’s exact part number and revision.

⚠️ If the rack is operating with a single power supply or is providing an active machinery-protection function, do not remove the TDI without following the approved maintenance procedure.

Stage 3 — Installing the 138607-01

Estimated time: 10–15 minutes

1. Verify the replacement module is 3500/22M 138607-01.
2. Inspect the connector and module guides for damage.
3. Align the module with the correct TDI slot.
4. Insert the module carefully into the rack backplane.
5. Secure the front-panel retaining hardware.
6. Verify that the associated rear I/O module is correctly seated and connected.
7. Reconnect the Ethernet or other approved communication connection.
8. Confirm that no neighboring module was disturbed during installation.

⚠️ Do not force the module into the rack. Misalignment can damage the backplane connector.

Stage 4 — Power-On & Testing

Estimated time: 20–30 minutes

1. Restore power according to the approved 3500 maintenance procedure.
2. Check the front-panel OK indication.
3. Verify the communication status indicators.
4. Confirm the rack reports a valid configuration.
5. Connect using the applicable 3500 configuration software.
6. Verify the TDI is recognized with the correct hardware identity.
7. Confirm communication between the rack and System 1 where applicable.
8. Verify that monitoring modules are supplying expected steady-state values.
9. If transient acquisition is configured, perform an approved functional test rather than generating an uncontrolled machine event.
10. Record the module revision, configuration, communication status, and commissioning results.

The 3500/22M front panel provides status indications including OK, TX/RX, TM, and CONFIG OK, which are useful during commissioning and troubleshooting.

FAQ

Q1. What is the Bently Nevada 3500/22M 138607-01?
It is the Standard Transient Data Interface (TDI) Module for the Bently Nevada 3500 Machinery Protection System. It interfaces the rack with compatible configuration and condition-monitoring software while collecting rack data.

Q2. Is 138607-01 the same as the complete 3500/22M assembly?
Not necessarily. 138607-01 identifies the standard TDI module, while the rear communication I/O module is a separate assembly. For example, 146031-01 is the 10Base-T/100Base-TX copper I/O module listed for the 3500/22M.

Q3. Can 138607-01 communicate with System 1?
Yes. The 3500/22M is designed to interface the 3500 monitoring system with System 1 Condition Monitoring and Diagnostic Software and 3500 System Configuration Software. External Ethernet communication is provided through the associated TDI I/O module.

Q4. Can I replace 138607-01 with 288055-01?
Do not treat this as an unconditional plug-and-play substitution. Current supplier documentation identifies 288055-01 as a replacement for the older 138607-01, but the complete rack hardware, I/O configuration, software compatibility, and installation requirements must be checked before migration.

Q5. Does 138607-01 itself provide the Ethernet connector?
The external network connection is associated with the rear TDI I/O module. The standard configuration uses 146031-01 for 10Base-T/100Base-TX copper Ethernet, while 146032-01 provides 100Base-FX fiber connectivity.

Q6. Does every 3500/22M 138607-01 support high-resolution transient data automatically?
No. Static data capture is standard, while dynamic and high-resolution transient acquisition depends on the configured options and system setup. Do not infer the enabled data-capture capability from the part number alone.

Q7. What should be verified before purchasing a replacement?
Verify the exact 138607-01 part number and revision, the existing rear I/O module, rack configuration, firmware/software compatibility, Ethernet or fiber interface, and required transient-data functions. If the application is being migrated to newer 3500 hardware, confirm the proposed replacement against the current OEM compatibility documentation rather than assuming electrical and software equivalence.
