• Power up the heads!
Receiver Alignment
• After a few seconds unplug the plugs of the motor controllers on both sides!
The motor control is a “light-buffer” this saves the power for the bad weather and in
the same time protects the receiver against overload. During the alignment it can be
used manually, to avoid the saturation, and keep the detector voltage on the level
where it can be still monitored. The detector voltage can be increased to seven volts;
above seven volts you won’t be able to monitor the detector voltage. This plate is
located in front of the receiver, and you can rotate it (clockwise decreases the
detector voltage, counter-clockwise increases).
• Follow the steps below
1 Switch on one of your transmitter on one side, and switch off all the others.
Switch off the transmitters on the other side too.
Orders of the switches:
You can check which transmitter is in use, after you switched on one of the
switchers, with the green LED on the back of every transmitter. Each LEDs are
indicates if them transmitters are functioning, and transmitting.
2 Move the head with the off switched transmitters until you can get the
biggest incoming light efficiency on the other side.
3 Fix the head as hardly as you can!
4 Repeat this with the other head too.
The receiver alignment should be done on both sides; the requirement is some
incoming light from the remote side (at least
receive). This alignment will determine the
position of the head and in the head the position
of the receiver. The idea is similar to the
focusing, but the only way to find the focus is to
move the head.
You can check the incoming light efficiency in two ways. Once you can use the
LEDs of the receiver. Second is to measure the detector voltage using the two pins
on the motherboard (if you have not got management in your head, then the
detector voltage is been measurable on the blue
and the brown wires of the heads own power
cable too).Because of the weight of the heads for the
vertical moving you can use the spacers as it is shown
on the figure. For this moving you need two wrenches.
With one of them you have to hold the head of the
bolt, and with the other you can turn the thick nuts to lift or loose the plate of the ABU.To
not enable any movement after the receiver alignment on the vertical angle of the head and
due to the heat expansion please close the locking nut under the thick nut, as it shown on the
figure, on both sides. Please note before the vertical receiver alignment we strongly suggest
doing the horizontal the same way as it is written above
