Monitoring & Metering
Preventative Maintenance:
The 3 Series allows users to track relay exposure to extreme environmental conditions by monitoring and alarming at high temperatures. This data allows user to proactively schedule regular maintenance work and upgrade activities.
Failure Alarm
The 3 Series detects and alarms on communication port and IRIG-B failures. The 3 Series also enables users to analyze system performance via diagnostics information such as event records, oscillography, etc.
Statistical Data
The 3 Series records statistical data in order to assist in diagnosing common motor faults, as well as assisting in planning preventative maintenance.
Advanced Device Health Diagnostics
The 3 Series performs comprehensive device health diagnostic tests during startup and continuously at runtime to test its own major functions and critical hardware. These diagnostic tests monitor for conditions that could impact and present device status.
