Install the shaft by sliding it through the hole
in the lower bearing assembly and into the
brush chamber.
The shaft should be pushed as far as
possible into the motor coupling so that the
contact brushes are properly aligned with
the electrical contact areas on the rotating
electrode shaft (see Figure 4.3).
If the shaft is properly installed, the brushes
will contact metal surfaces on the shaft.
If the shaft is improperly installed, the
brushes may contact an insulating gap on
the shaft, and the connection to the
rotating electrode will fail.
Use the hex driver tool (5/64") to securely
tighten both hex screws on the motor
coupling.
Gently tug on the shaft to make sure it is
securely mounted in the motor coupling.
Close the clamshell doors and tighten the latch.
Remount the motor unit on the center post (in the non-inverted position).
CAUTION:
Before reconnecting the rotator power cable or the motor
control cable to the control unit, be sure the control unit power
switch is off and the rotation rate knob is turned to the fully
counterclockwise position.
ATTENTION:
Avant de reconnecter le câble d’alimentation du rotateur ou le câble de
commande du moteur à l’unité de commande, assurez
-vous que
l’interrupteur de l’unité de commande est en position éteinte et que le bouton
de commande de la vitesse de rotation est complètement tourné dans la
position inverse des aiguilles d’une montre.
Reconnect the motor control cable from the control unit to the motor unit.
Reconnect the power cable from the power source to the control unit.
