Description

Bently Nevada 2300/20-00-01 is a compact 2-channel vibration & speed monitor

Product Title & Description

Model: 2300/20-00-01 The Bently Nevada 2300/20-00-01 is a compact 2-channel vibration & speed monitor for balance-of-plant rotating machinery protection. It is an economical standalone machinery protection unit designed for continuous vibration measurement, alarm and trip protection for pumps, fans, motors and small compressors. Equipped with built-in LCD display, relay alarm outputs, 4–20mA analog outputs and Modbus TCP Ethernet, it is widely used in power, oil & gas, water treatment and pulp & paper industries for predictive condition monitoring and machinery protection.

Core Product Overview

2300/20 series monitors are cost-effective standalone protection instruments from Bently Nevada, used for non-critical auxiliary rotating equipment (BOP equipment). This unit has 2 vibration measurement channels plus 1 speed/keyphasor channel. It accepts inputs from proximity probes or seismic accelerometers to measure vibration, velocity, displacement, and also track shaft RPM. The integrated LCD screen shows real-time measured values, alarm status and fault information locally. Two configurable relays provide alert and danger trip outputs for interlock protection. Dual 4–20mA analog outputs send vibration data to DCS/PLC, while Modbus TCP enables remote data access for asset condition monitoring software. It supports envelop demodulation for early bearing and gear fault detection. It can be used as a replacement for older Bently 1900/27 monitors.

Installation & Configuration Guide

7.1 Pre-installation Preparation

Verify model 2300/20-00-01, inspect housing, terminals and LCD for damage. Prepare 24VDC power supply, shielded sensor cables, proximity probes / accelerometers, shielded Ethernet cable and Bently 2300 configuration software. Cut power before installation, wear ESD protection. Confirm sensor type and measuring range.

7.2 Installation Steps

Mount the monitor on standard DIN rail inside control cabinet. Wire 24VDC power supply to power terminals. Route shielded sensor cables from vibration and speed transducers to monitor input terminals, single-point shield grounding at cabinet side. Wire relay output terminals to plant interlock circuit. Connect Ethernet cable for Modbus TCP communication. Tighten all terminals, keep adequate ventilation space around unit.

7.3 System Configuration & Commissioning

Launch Bently 2300 configuration software, connect to monitor via Ethernet. Set each channel sensor type, measurement unit, alarm and trip threshold values. Configure 4–20mA mapping and relay action. Download configuration to monitor. Power up, verify LCD reading and LED status. Inject simulated vibration/speed signal to test alarm and relay trip function. Test Modbus TCP data reading from DCS or monitoring system. Record commissioning parameters and alarm setpoints.

7.4 Maintenance & Precautions

During planned outages, inspect cable tightness, shield integrity and cabinet temperature. Check probe cable insulation and connector condition. Do not exceed rated 24VDC supply. Do not open the enclosure. If wrong readings or false alarms occur, check sensor, cable and probe gap before replacing the monitor.
