Product Introduction
Bently Nevada 167699-02 is the display and keypad module for the 1900/65A General Purpose Equipment Monitor. It provides a local LCD interface for checking vibration and temperature channels, alarm status, and basic monitor settings.It can be mounted directly on the 1900/65A or installed remotely up to 75 m (250 ft) away. That makes it useful when the monitor is in a junction box, skid, or control panel, but operators still need local visibility. It does not replace the 1900 Configuration Software for full setup.
Installation & Configuration Guide
Preparation — about 10 minutes
- Confirm the monitor model is 1900/65A.
- Check the ordering code. Option B01, B02, B03, B04, or B05 indicates a display variant; 167699-02 is the display/keypad hardware.
- Power down the 1900/65A before connecting or disconnecting the display cable unless the site procedure explicitly allows live work.
- Inspect the display connector, cable, and sealing gasket if a weatherproof housing is used.
Removal — 5–10 minutes
- Label the display cable if it is remotely mounted.
- Disconnect the display cable from the 1900/65A.
- Remove the display from its mounting bracket or panel.
- Place the module in an ESD-safe bag.
Installation — about 10 minutes
- Verify the 1900/65A is de-energized before mating connectors.
- Mount the display securely. If it is remote-mounted, keep the cable away from high-voltage runs and VFD output cables.
- Connect the display cable firmly. A loose connector is a common cause of blank screens.
- Restore power to the 1900/65A.
Power-On & Test — about 10 minutes
- Check that the LCD powers up.
- Scroll through channels and confirm values match the monitor status.
- Verify alarm indications appear when the monitor is in Alert or Danger.
- If the display remains blank, reseat the cable and confirm the 1900/65A is powered and healthy.
Troubleshooting Quick Reference
| Symptom | Most Likely Cause | First Check |
|---|---|---|
| Blank display | No power or loose cable | Confirm 1900/65A is powered; reseat display connector |
| Display shows incorrect channel | Wrong monitor addressed | Verify the display is connected to the correct 1900/65A |
| Alarms not visible | Display contrast or navigation issue | Adjust contrast; check channel view menu |
| Intermittent display | Cable damage or poor termination | Inspect remote cable, strain relief, and connector pins |
| Display works but cannot change settings | Limited keypad function | Use 1900 Configuration Software for full configuration |
| Fault after remote mount | Cable length or wiring issue | Confirm cable type and length are within the 75 m (250 ft) limit |
Dimensions, Mounting & Wiring Notes
- Mounting: Direct mount on 1900/65A or remote panel mount.
- Dimensions: Approximate display size 7.75 × 5.03 × 1.29 in per 1900/65A datasheet; confirm exact mechanical drawing before cutting a panel.
- Cable: Use the correct display cable specified for 1900/65A. PVC and TEF variants are available depending on environment.
- Sealing: If installed in a NEMA 4X/IP66 housing, verify the door window, gasket, and cable gland.
- ESD handling: Treat the LCD and keypad as sensitive electronics. Avoid touching the connector pins.
FAQ
Is 167699-02 the same as the 1900/65A monitor?
No. 167699-02 is the display/keypad. The 1900/65A is the monitor that processes vibration and temperature inputs and drives relays and 4–20 mA outputs.Can I mount it away from the monitor?
Yes. The display can be mounted up to 75 m (250 ft) from the 1900/65A with the correct cable.Does it work with other Bently Nevada monitors?
It is specified for the 1900/65A. Do not assume compatibility with 3500, 2300/20, or other 1900 models without OEM confirmation.Can I do full configuration from the keypad?
Only limited changes. Full channel, relay, filter, and Modbus configuration should be done with the 1900 Configuration Software.Why is my display blank after replacement?
Most often the cable is loose, the monitor is not powered, or the connector was damaged. Check power first, then reseat the cable.Do you supply the cable with the display?
That depends on the item. Some units include the cable; others do not. Confirm the part list before shipment.Is this item new or refurbished?
Both conditions may be available. Each unit is listed as New Surplus, Factory Sealed, or Refurbished (Tested). The exact condition and test result are confirmed per order.
