6. Troubleshooting

If careful attention to phase rotation is not made during connection of the panel to the three-phase power

supply and motor, then there is only a one chance in four that the motor will rotate correctly in both drive and

bypass modes.

The other three possibilities and the corresponding corrective actions are as follows:



Problem: Motor turns correctly in Bypass mode and incorrectly in Drive mode

Solution: Swap two of three power supply leads AND two of three motor leads



Problem: Motor turns correctly in Drive mode and incorrectly in Bypass mode

Solution: Swap two of three power supply leads



Problem: Motor turns incorrectly in both modes

Solution: Swap two of three motor leads

Note that if the rotation in bypass mode is opposite to the rotation in drive mode, it is possible that the panel’s

motor overload will trip if a full-speed transition between modes is attempted. This is due to the large amount

of current required to decelerate the motor to a stop prior to accelerating it in the correct direction.
