Description
Product Overview
The 167699-02 display module attaches directly to the 1900/65A monitor to show real-time channel data, alarm conditions, and configuration parameters through an integrated LCD screen and keypad. It enables standalone operation without requiring a separate PC or HMI for basic monitoring and adjustment tasks in industrial machinery protection systems.

Technical Description
The display module connects to the 1900/65A’s internal bus, mirroring processed vibration, position, speed, and temperature data from up to four transducer inputs and four temperature inputs. Users navigate menus to view peak/RMS values, set OK/Alert/Danger thresholds, adjust filter settings, and configure relay logic. Buffered outputs from channels 1-4 can drive external displays or recorders, while the keypad supports local inhibit, reset, and trip multiply functions.
Usage Instructions
Attach the 167699-02 directly to the 1900/65A monitor before powering up.
- Align and snap the display module onto the monitor’s front connector.
- Power the system and verify display initialization (all segments test).
- Use keypad arrows to select channels and view measured values vs. alarm setpoints.
- Enter configuration mode to adjust full-scale ranges, filters, and relay logic.
- Test alarms by simulating inputs and confirm relay operation.
- For software configuration, connect PC with 1900 Configuration software via RS-485.
Common Questions
Q: Does the display module store configuration data?
A: No, configurations are stored in the 1900/65A monitor’s non-volatile memory. The display provides local access only.
Q: Can I use the display in hazardous areas?
A: Yes, when installed in approved NEMA 4X/IP66 enclosures with proper certifications.
Q: What transducers are compatible?
A: Accelerometers, velocity sensors, proximity probes, thermocouples, and RTDs; default settings optimized for Bently Nevada sensors.
Q: How do I reset latched alarms?
A: Press the Reset button on the keypad after correcting the condition, or use remote reset inputs.
Q: Is firmware field-upgradable?
A: Firmware updates require Bently Nevada service tools and authorized personnel.
