Description
Product Introduction & Engineering Value
When a machine enters an alarm condition, operators should not have to connect a laptop simply to determine what happened. The Bently Nevada 167699-02 Display Module provides a dedicated local interface for the 1900/65A General Purpose Equipment Monitor, making operating conditions immediately visible at the equipment location.
The module combines a backlit LCD, status LEDs, and a keypad to display vibration measurements, alarm status, and diagnostic information. It can also be remotely mounted away from the monitor, making it suitable for installations where the monitoring electronics are located inside a control cabinet while the operator interface remains accessible on a panel door.

Field Application & The “Trench” Experience
A water treatment facility relied on several cooling water pumps protected by 1900/65A monitors installed inside a locked electrical room. During a nighttime maintenance call, operators repeatedly had to enter the control cabinet just to determine whether a vibration trip originated from the pump or its motor.
During the next outage, engineers installed a replacement 167699-02 Display Module on the exterior panel door while leaving the monitor inside the enclosure. After commissioning, technicians could immediately view vibration values, alarm history, and machine status without opening energized cabinets. The change reduced troubleshooting time and improved maintenance safety.
Typical applications include:
- Cooling water pump vibration monitoring
- Process fan condition monitoring
- Auxiliary turbine and gearbox protection panels

Transparency SOP: QA & Testing
Every New Surplus or professionally refurbished 167699-02 is processed through a documented quality inspection.
- Verify the LCD, keypad, and LED indicators for proper operation.
- Inspect the enclosure, display window, and connectors for mechanical damage.
- Confirm part number, hardware revision, and manufacturer identification.
- Test communication with a compatible 1900/65A monitor.
- Verify display readability, keypad response, and alarm indication functions.
- Package the unit using anti-static protection and impact-resistant industrial packaging.
The Veteran’s Tech Trap Guide
⚠️ This isn’t the monitor itself.
The 167699-02 is the display module for the 1900/65A Monitor. It does not perform vibration monitoring independently and must be connected to a compatible 1900/65A monitor.
⚠️ Inspect the display cable before replacing the module.
Many apparent display failures are actually caused by damaged interconnecting cables or loose connectors rather than a faulty display module.
PRO TIP:
If you’re replacing a display because the LCD appears blank, verify the monitor’s power supply and communication cable first. In the field, connector issues are encountered more frequently than actual display failures.
Dynamic FAQ
Q1. What is the function of the 167699-02?
The 167699-02 provides the local operator interface for the 1900/65A General Purpose Equipment Monitor, displaying machine measurements, alarm conditions, and system status through a backlit LCD and status LEDs.
Q2. Can the display be mounted away from the monitor?
Yes. The display can be installed as far as 75 meters (250 feet) from the monitor module, allowing convenient panel-mounted operation while the monitor remains inside a control cabinet.
Q3. Can configuration changes be made from the display?
Yes. The integrated keypad supports basic local configuration and navigation functions for the connected 1900/65A monitor. More advanced configuration is typically completed using the appropriate software tools.
Q4. Is the 167699-02 compatible with the 3500 Series?
No. It is designed specifically for the 1900/65A General Purpose Equipment Monitor and is not interchangeable with display or interface modules used in the 3500 Machinery Protection System.
Q5. What does “New Surplus” mean?
A New Surplus unit is an unused OEM component from excess inventory or canceled projects. It has not been installed in service and is inspected to verify identification, cosmetic condition, and functionality before shipment.
Q6. Is warranty coverage available?
Yes. Warranty availability depends on the inventory condition and supplier’s policy. Both New Surplus and professionally refurbished units are typically supplied with documented inspection results and warranty coverage after functional verification.
