    Figure 2. Phase Indication Table (shown on the rear of the Motor and Phase Rotation indicator) Non-contact Rotary Field Indication For non-contact rotary field indication: 1. Disconnect all test leads from the Motor and Phase Rotation indicator. 2. Position the Indicator on the motor so that it is parallel to the length of the motor shaft.
  • Page 6 for testing. Either the Clockwise or Counter Clockwise Rotary indicator illuminates showing the type of rotary field direction present. Note The indicator will not operate with engines controlled by frequency converters. The bottom of the Motor and Phase Rotation indicator should be oriented towards the drive shaft.
