the installation/acceptance check off. If the readings differ by more than five percent, refer to appropriate troubleshooting information and perform applicable corrective action. Then take voltage readings off each of the three conductors; the readings should agree with each other within two percent. Turn the FEED CCW/OFF/CW switch to OFF.

Repeat preceding step (3) with the FEED CCW/OFF/CW switch in the alternate operat- ing position.

Turn the AZIMUTH EAST/WEST switch to either position and while the antenna is rotat- ing, carefully use a clamp on ammeter in accordance with the ammeter manufacturer’s instructions to take current readings off each of the three conductors (phases) connect- ed to the load side of the azimuth drive motor circuit breaker. Record the current draw in the equipment log and compare the readings to the reference values entered in the installation/acceptance check off. If the readings differ by more than five percent, refer to appropriate troubleshooting information and perform applicable corrective action. Then take voltage readings off each of the three conductors; the readings should agree with each other—within two percent. Turn the AZIMUTH switch to OFF.

Repeat steps (5) with the AZIMUTH EAST/WEST switch in the alternate operating posi- tion.

Turn the ELEVATION DOWN/UP switch to either position and while the antenna is rotat- ing, carefully use a clamp on ammeter in accordance with the ammeter manufacturer’s instructions to take current readings off each of the three conductors (phases) connect- ed to the load side of the elevation drive motor circuit breaker. Record the current draw in the equipment log and compare the readings to the reference values entered in the installation/acceptance check off. If the readings differ by more than five percent, refer to appropriate troubleshooting information and perform applicable corrective action. Then take voltage readings off each of the three conductors; the readings should agree with each other within two percent. Turn the ELEVATION switch to OFF.

Repeat steps (7) with the ELEVATION DOWN/UP switch in the alternate operating posi- tion.

If all voltage and current readings are within tolerance, close the local control/motor drive controller inner door and place the LOCAL/REMOTE switch in the REMOTE posi- tion to return antenna control to the studio. Then close and lock the outer local control/motor drive controller door.
