Applications and Use Cases

The 2300/20_KIT-002-00 is suitable for rotating machinery monitoring in industries such as oil and gas, power generation, and manufacturing. It supports accelerometers, velocity sensors, and proximity transducers, making it versatile for various machine types. For example, it can monitor radial vibration on pumps, thrust position on compressors, and speed on turbines. Additionally, the process variable channel can accept most units with default settings, allowing integration with temperature or pressure transducers.

Installation and Setup

Mounting is flexible with panel mount or DIN rail options, and the adapter is included. The housing kit (105M6193-01) is a fiberglass enclosure for nonhazardous areas, while the stainless steel version (105M6193-03) is for hazardous areas. The kit includes a 6 ft. (1.8 m) shielded Ethernet cable and a 17 ft. (5.2 m) cable for the accelerometer. Ensure the power supply provides 18 to 36 Vdc and does not exceed 7.5 W. For 4-20 mA outputs, note that they will not work with an external powered loop; use the internal current loop power supply.

Maintenance and Reliability

Regular inspection of the monitor and sensors is recommended to ensure accurate readings. The relay contacts are rated for 100,000 cycles at 5 amps, so periodic testing of alarm and relay functions is advised. The real-time clock battery has a long life—38 years when powered and 12 years un-powered at 50°C—reducing maintenance frequency. In case of network disruption, the 2300 can store up to at least 5 alarm data captures (requires System 1 Evolution 21.1 or newer and firmware 3.2 or newer).

Compatibility and Integration

The 2300/20_KIT-002-00 communicates via Ethernet (10Base-T/100Base-TX) and is compatible with Bently Nevada System 1 software. It supports Bently transducers or 2/3 wire custom transducers for accelerometers, velomitors, and proximitors. The monitor provides three contact inputs for configuration lock, latched alarm/relay reset, and bypass functions. An external button can reset latched alarms and relays.

Troubleshooting and Common Issues

If the monitor does not communicate over Ethernet, check the cable length (max 100 meters) and ensure the RJ-45 connection is secure. If the 4-20 mA outputs are not working, verify that no external power is connected to the loop. For speed channel issues, confirm the threshold voltage resolution is set correctly (0.1 Vdc). The OK LED indicates proper operation; if it is off, consult the manual.
