Level 2 Online Condition Alarm

Applications and Occasions

• Sites that need 24-hour watch and alarms when limits are exceeded, without dedicated vibration analysts.
• Severity monitoring (ISO vibration grading) of pumps, fans, motors and compressors.
• Replaces routine walk-around inspection across many points.

Setup and Usage

1. Install the sensors on the measurement points and daisy-chain them over RS485 to a PC, industrial computer or sensor hub.
2. Choose how to read the data (one of three):
   • Aurora Middleware Modbus: the vendor middleware that reads the sensors' Modbus registers and can log data to CSV files.
   • IOTech EdgeXpert: an edge gateway that collects Modbus data and forwards it to upstream systems; locally, its dashboard shows the sensors' current vibration data and status directly.
   • Develop your own: Level 2 / Level 3 work by Modbus address (register point). Using the vendor Modbus address map, users can write their own middleware to read each point's vibration data and health status directly.
3. View with Aurora Middleware Dashboard: shows health, trends and alarm status for each point with no custom screens needed. It must be used together with Aurora Middleware Modbus.
4. Configure and maintain with Aurora Modbus Utility (addresses, parameters, firmware).

Alarm decisions are made in the sensor; the platform collects, displays and notifies.
