Bently Nevada 167699-02
Product Overview
The Bently Nevada 167699-02 is the dedicated display and operator-interface module for the 1900/65A General Purpose Equipment Monitor. It is not the primary vibration-processing controller and should not be treated as a standalone machinery monitor. Its job is more specific: provide technicians and operators with local access to the measurements, status information, alarm conditions, and basic configuration functions handled by the 1900/65A monitor. Bently Nevada documentation lists the 167699-02 directly as an accessory for the 1900/65A platform.
For an installed 1900/65A system, that distinction matters during procurement. Replacing the display does not replace the monitor’s measurement electronics, relay outputs, recorder outputs, or communication functions. Those remain associated with the main monitor assembly. The 167699-02 can be mounted with the monitor or positioned remotely, with documented cable configurations extending to 75 m (250 ft). This makes it useful where the monitoring electronics remain inside an equipment cabinet while the operator interface is positioned on a cabinet door or another accessible panel.
In practical maintenance work, the Bently Nevada 167699-02 is therefore a replacement-interface component rather than a general-purpose HMI. The six-button keypad and backlit LCD provide a local operating point without requiring a laptop for every basic inspection or adjustment. Available technical documentation identifies status indication for conditions such as OK, Alert, Danger, Bypass, and Trip Multiply.
The physical display assembly is approximately 196.9 × 149.4 × 32.8 mm according to published technical listings, while environmental specifications commonly associated with the display assembly are approximately -20°C to +70°C operating and -40°C to +85°C storage.
Product Introduction
A failed front interface can leave an otherwise serviceable 1900/65A installation awkward to operate and diagnose. The Bently Nevada 167699-02 addresses that specific maintenance problem by restoring the local display/keypad interface rather than forcing replacement of the complete monitoring system.
Remote mounting is one of its practical advantages. With a maximum documented separation of 75 m (250 ft), the display can be installed where operators actually need access while the main 1900/65A monitor remains in the instrumentation cabinet.

Major Features and Advantages
Dedicated 1900/65A Interface
The Bently Nevada 167699-02 was designed specifically around the 1900/65A monitoring platform. That makes system matching more important than simply finding a display with similar dimensions. The interface has to communicate correctly with the host monitor and support the operating functions expected by the 1900/65A architecture.
Local Display and Keypad Operation
The backlit LCD provides local visibility of monitor information, while the physical six-button keypad gives technicians a direct control interface. This is particularly useful during commissioning, troubleshooting, alarm investigation, and routine maintenance when connecting a service computer is unnecessary.
Remote Panel Installation
A major installation feature is the ability to locate the display separately from the main monitor. Published documentation supports remote display arrangements up to 75 m (250 ft) using the appropriate interconnecting cable.
For cabinet-mounted machinery protection systems, this can be more useful than it sounds. The monitor can remain protected inside an instrumentation cabinet while the display is placed at an accessible operator position.
Status Indication
The interface provides dedicated indication for important monitor states, including OK, Alert, Danger, Bypass, and Trip Multiply. These indicators allow technicians to identify the general state of the monitoring system without immediately opening the cabinet or connecting external diagnostic equipment.
Replacement-Oriented Architecture
The 167699-02 is a component-level replacement item. This is useful when the installed 1900/65A monitor itself remains operational but its display, keypad, or local interface has failed. Replacing only the affected interface can avoid an unnecessary change to the measurement and protection portion of the installation.

FAQ
Is the Bently Nevada 167699-02 a complete vibration monitor?
No. The 167699-02 is the display/operator-interface module for the 1900/65A. The actual measurement, processing, alarm, relay, and communication functions belong to the main 1900/65A monitor assembly.
Can I use 167699-02 with another Bently Nevada monitor?
Do not assume compatibility based only on physical appearance. The documented application is the 1900/65A General Purpose Equipment Monitor. For a replacement project, match the installed host monitor, connector arrangement, cable configuration, and hardware revision before ordering.
Can I hot-swap this module?
Treat the 167699-02 as a powered electronic assembly unless the applicable Bently Nevada installation procedure for your exact configuration explicitly permits live replacement. In normal maintenance, power isolation and appropriate ESD precautions are the safer procedure.
Does 167699-02 process vibration signals itself?
No. The display is an operator interface. Vibration and temperature measurement processing is performed by the 1900/65A monitor. The display presents information generated by the host system rather than replacing its measurement electronics.
Can the display be installed remotely?
Yes. The published 1900/65A documentation supports display installation up to 75 m (250 ft) from the monitor using the appropriate cable arrangement. Cable selection matters at longer distances because signal characteristics change with cable length.
Does this part contain the 1900/65A configuration or monitoring logic?
Do not assume that it does. The 167699-02 is the operator interface; configuration and monitoring functions reside in the host 1900/65A equipment monitor. When replacing an interface, verify the existing monitor’s configuration separately.
What should I verify when buying a New Surplus 167699-02?
Verify the complete part number 167699-02, physical connector condition, LCD condition, keypad operation, indicator operation, included cable or mounting hardware, and compatibility with the installed 1900/65A monitor. “New Surplus” describes inventory condition; it does not, by itself, prove that the assembly has never been installed or electrically tested. For a critical machinery-protection application, functional inspection is worth requesting before shipment.
