- ▪ Measures and displays current, voltage, earth-fault current, active/reactive power, energy, operating time, total operating time and power factor
- ▪ Fault-cause display, plus a fault wave record sampling 3-phase current and voltage at 1 ms for 200 ms around a trip (readable over communication)
- ▪ Total operating-time counter that the user cannot reset — only cleared in the factory
- ▪ Date and time stamping of faults, so a motor failure can be placed exactly
- ▪ Restart limit caps reset attempts within 30 minutes when auto reset is enabled
- ▪ Self test runs watchdog and RAM checks while the motor is not drawing current
- ▪ Communication watchdog raises an alert if the PLC/DCS stops polling for a user-set 1–999 s
