PLEASE NOTE; the microchip is programmed to Northern Hemisphere, Note; On Northern Hemisphere Sensors the red indicator is warning you it is thinking of heading west, for which there is about a 1 to 2 minute delay. green indicator is for east= with 8 to 12 minutes time delay. .Battery & motor wires are marked on the sensors. Should the tracker go the wrong direction simply reverse the two wires to the actuator to change it's direction. NOT at the battery. General operating instructions can be found on my web site at www.campatracka.com and follow the relivent links. but remember our web site instructions are bassed on Southern Hemisphere conditions. Be sure to place an inline fuse to the power supply of around 5 to 7.5 amp rapid blow. If for some reason the sensor seems dead, simply disconect power for 1 minute & reconnect power. If driving heavy current actuators it pays to have a fuse also on each supply from the sensors to the actuators. Around 5 to 7.5amp. As with all electronics the circuit is electrostaticly sensitive and you should only handle the board by holding the edge of the board. Never handle the board with power conected. These sensors now have a sleep mode within the program. This simply meens that after the auto park has returned the tracker to east, it will count aprox 10minutes, then switch to powersaver mode. this vertually cuts all power within the sensors until sunrise the next day. Should you accidently activate the auto park, just disconect and reconect power to the sensors. this is sort of like rebooting your pc, and restarts the program from the start.

If you wish to box the sensor, I have included two extra LEDs and an LDR, or light dependant resistor. follow the info provided below and you cant go wrong.
Be sure your limmit switches are working on the tracker east west axis befor connecting these sensors. If not fully operational the lack of limmit swiching will cause permanant damage to the sensors.
ALWAYS have a 7.5 amp fuse on the battery + supply, and if possible it is best to have a fuse on each motor wire. This way if a limmit switch becomes faulty the fuse should blow befor the sensors fry themselves.
Have fun, and Smile Damn it...!

Some LED info on LEDS supplied
The red LEDs are my Favorite for all round stability. With a 60% viewing angle they balance perfectly in heavy cloud, usually making the tracker park in the midday possition in heavy weather.
The clear green are less viewing angle but more sensitive, which is ok, but when
weather gets very heavy it will sea through more cloud than the reds, but is inclined
to search around more than the reds. And lets face it, if its that cloudy your panels won't
gain much anyway. But they are favoured for Mirror heater use due to better precission
The Yellow defused are similer to the clear green, but even more sensitive. Possibly making them
better for Northern Hemisphere users in their long, low sun winter times.
Hope the above info helps. If you find the perfect LED for N/Hemisphere use let me know please
