Installation Guidelines

Follow these steps to install your Bently Nevada 2300/25-00 monitor correctly.

1. Select Mounting Location – Choose a clean, dry area within temperature range.

2. Mount the Monitor – Use panel mount or DIN rail adapter (included).

3. Connect Power – Wire 18 to 36 Vdc to DC input terminals.

4. Ground Properly – Use COM to chassis ground jumper or separate earth ground.

5. Connect Sensors – Wire accelerometers, proximity probes, or velocity sensors.

6. Configure Channels – Set scale factor, full scale range, and filter values.

7. Connect Ethernet – Plug RJ45 cable for System 1 communication.

8. Apply Power – Verify green OK LED illuminates.

Do not exceed 36 Vdc input voltage. Higher voltage will damage the monitor.

Frequently Asked Questions (FAQ)

1. What sensor types work with the Bently Nevada 2300/25-00 monitor?
The 2300/25-00 accepts ICP accelerometers, velocity sensors (Velomitor), and proximity transducers (Proximitor). Keyphasor and magnetic pickup inputs are also available.

2. What is the accuracy of the 2300/25-00 measurement channels?
Each channel provides ±1% of full scale range accuracy. Independent 24-bit ADCs ensure high resolution measurements.

3. How many buffered outputs does this monitor provide?
The 2300/25-00 provides three buffered outputs via BNC connectors. Two are for vibration signals and one is for speed signal.

4. Can I mount the 2300/25-00 on a DIN rail?
Yes. The 2300/25-00 includes a DIN rail adapter. Panel mount is also supported.

5. What happens to alarm data if the network fails?
The monitor stores up to 5 alarm data captures locally. Data transfers to System 1 when network connection restores.

6. What is the operating temperature range for this monitor?
The 2300/25-00 operates from -30°C to +65°C (-22°F to +149°F). This suits outdoor and harsh industrial environments.

Why Choose This Model?

The Bently Nevada 2300/25-00 offers compact machinery protection with SPA outputs. Its multiple channel types (accelerometer, velocity, proximity, Keyphasor) cover most rotating machinery monitoring needs. The independent 24-bit ADCs deliver high accuracy without channel cross-talk. The SPA outputs provide buffered signals for portable data collectors and spectrum analyzers. The Ethernet communication integrates with System 1 software for centralized monitoring. The two relay outputs provide alarm and danger indications for local safety circuits. The wide operating temperature (-30°C to +65°C) suits outdoor installations in extreme climates. Choose this 2300/25-00 for fans, pumps, compressors, and small turbines requiring compact protection monitoring with diagnostic output capabilities.
