Bently 167699-02 1900/65A 16769902 operation panel

Bently Nevada 167699-02 (1900/65A Operation Panel) Complete Information

I. Basic Product Definition

Material Number: 167699-02 (Abbreviation: 16769902)

Series: Bently Nevada 1900 General Equipment Monitoring Series

Main Unit: 1900/65A General Rotating Machinery Monitor

Product Type: Split-type local HMI control panel, cannot work independently, must be plugged into the front of the 1900/65A main unit. It is the only local operation unit for on-site viewing, alarm reset, and simple configuration of the unit.

II. Hardware Appearance and Indicator Configuration

Backlit LCD Display Screen

Screen size: 68.6mm × 35.6mm, can cycle through 8 channels of real-time measurement values, alarm thresholds, sensor fault codes, 200 event records, simple trend curves, and supports switching between multiple engineering units such as vibration, shaft displacement, speed, and temperature.

Status Indicator Group

OK: Normal operation indicator;

ALERT: Alarm triggered by warning threshold;

DANGER: Alarm triggered by dangerous trip threshold;

BYPASS: Channel bypass shielding activated;

TRIP MULTIPLY: Trip multiplication function enabled;

CH1~CH8 Independent channel lights, indicating channel online, disconnected, and short-circuit fault status.

Physical Operation Buttons

ESC: Exit; MENU: Menu; Up/Down/Left/Right Navigation; RESET: Alarm Reset; BYPASS: Channel Bypass Switching. Basic parameters can be modified locally without a host computer.

Panel Interface

A dedicated serial bus interface is built into the rear panel, communicating with and powered by the 1900/65A host unit, requiring no external power supply. A single-channel BNC buffered signal output port with a bandwidth of 40kHz is integrated on the side, capable of outputting raw sensor waveforms from any channel for field probe and preamplifier calibration. It features short-circuit and EMI protection design.

III. Core Operating Functions

Real-time Data Inspection

Simultaneously monitors 4 dynamic signal channels (eddy current, velocity, acceleration, and speed probes) + 4 temperature channels (thermocouple/RTD), freely switching between single-channel and multi-channel polling display.

Alarm Event Management

Local one-click reset of self-locking early warning/hazard alarms; retrieves cached event logs, fully recording alarm time, triggering channel, fault type, sensor loop failure, and module communication anomaly records.

Local Configuration Settings

No 1900 configuration software is required on-site; channel type matching, early warning/hazard threshold setting, 4-20mA transmitter range configuration, relay logic, and bypass function switching are completed through the panel menu.

System Self-Diagnosis and Testing

One-click hardware self-test, quickly identifying probe disconnection, short circuit, power supply abnormality, and interruption of communication between the panel and the host; the screen directly outputs the fault channel number, shortening fault diagnosis time.

Waveform Verification Output

BNC buffered output adapts to an oscilloscope, allowing for the reading of raw vibration waveforms during on-site debugging to verify sensor installation gaps, signal attenuation, and preamplifier operating status.

IV. Physical and Environmental Specifications

Overall Dimensions: 196.9mm × 149.4mm × 32.8mm

Net Weight: 0.40kg

Operating Temperature: -20℃ ~ +70℃, Storage Temperature: -30℃ ~ +90℃

Humidity: 5%~95% RH, non-condensing

Electromagnetic Compatibility: Complies with EN 61000-6-2 industrial anti-interference standard, with overall shielding and filtering

Explosion-proof Certification: Class I Zone 2 / Div 2, T4 temperature group, suitable for explosion-proof control cabinets in oil and gas and chemical industries.

V. Installation Methods

Standard Direct Mount: Snap-fit fixed to the front of the 1900/65A main unit; the entire unit is mounted on a uniform 35mm DIN rail cabinet.

Optional Split Wall Mount: With an isolation mounting base plate, it allows for external operation of the control cabinet door panel.

Optional Outdoor Protection: Equipped with a NEMA 4X/IP66 glass window protective housing, suitable for on-site control cabinets.
