The information given below concerns the AR-40 Antenna Rotator manufactured by Hy-Gain.
For in-depth description, the user should refer to the manufacturer documents.
Pre-Installation Check and Calibration.
Before mounting the rotator unit on the considered mast or tower, check the operation with the
control unit and cable. Strip all conductors at both ends of the cable and attach to the
terminals. Connect terminal 1 to terminal 1, etc. On the control box, simply insert the bare
wire between the nut and the terminal and tighten the screw. Do not wrap the wire around the
screw!
Plug the control unit line cord into a convenient wall outlet. Turn the direction control knob to
'N'. Momentarily press down on the start button. The rotator will start to turn and the indicator
light will come on. When the rotator reaches 'N', it will automatically stop and light-will go
off.
Turn the knob COUNTERCLOCKW/SE to 'S' and press the start button. If the rotator unit
stops before the South position and the indicator light turns off, adjust the 'CCW end of
rotation' shaft counterclockwise as far as it will go. The adjustments for end of rotation are
located on the bottom side of the control box. Tm~ the unit to 'W', stop, then again to 'S', using
the method as described previously. If the control light remains on this time, slowly turn the
'CCW' shaft clockwise until the light goes off.
Turn the knob CLOCKWISE to 'S' and press the start button. The rotator unit should turn
clockwise toward the 'SOUTH' position. If the rotator stops before reaching the 'SOUTH'
position and the indicator light turns off, adjust the 'CW end of rotation' shaft clockwise as far
as it will go. Turn the unit to 'E', stop, then again 'back to 'S'. If the light remains on, slowly
turn the 'CW' shaft counterclockwise until the light turn off.
