ROTATOR CONTROLLER USER GUIDE.
When power is applied to the controller, the “New” heading will be set to 180 degrees. The “Power”
LED will light when power is applied to the controller.
Press the A or B button to select which rotator is to be controlled.
Note that wind and loading at the top of the rotator will affect the speed of rotation and accuracy of
the final heading. Strong winds may cause the rotator to “windmill” and not remain at the heading it
was set to. This is due to either the high loading of the rotator by large antennas or the brake (if
fitted) not locking the rotator.
The rotator controller has switching contacts to control a brake (if fitted)
When rotating, the brake is released shortly before the motor power is applied and operated again
shortly after the power has been removed from the motor.
The controller will not work correctly until the rotator has been calibrated as described in the
Program Mode section.
Normal Mode:
This is the usual or standby mode.
Rotate the dial until the desired direction is indicated in degrees.
Press the dial button once. The rotator will begin to move to the desired heading.
To stop the movement at any time, press the dial button once.
To resume, press the dial button once again. When the rotator is within approximately 3 degrees of
the desired heading, power is removed from the motor.
The final heading when the motor stops will depend on the wind and amount of loading at the top of
the rotator but will be within 3 degrees of the desired heading.
Follow the Dial Mode:
To enter the Follow the Dial Mode, press the dial button twice. The rotator will begin to move to the
desired heading. At any time, the dial may be moved to a new heading. The rotator will begin to
move to that heading. When the rotator is within approximately 3 degrees of the desired heading, it
will stop rotating. A new heading may be dialed and the rotator will begin to move to that heading
automatically.
If the dial is not changed in 90 seconds, the controller will switch back from Follow the Dial to
Normal Mode.
Park Position Memories:
To set the rotator to one of four preset Park position headings in memory, press the dial button 3
times. Rotate the dial to the required Park position memory then press the dial button. The rotator
will move to within several degrees of that heading.
