Warning in VLT FC301/ FC302 : External Interlock - comes when a digital input signal indicates a fault condition external to the drive. An external interlock has commanded the drive to trip.
1. Clear the external fault condition.
2. To resume normal operation, apply 24 V DC to the terminal programmed for external interlock.
3. Reset the drive.
