I thought that it might be fun to "salvage" the electric eye sensors forI was also interested to see how they worked, since there are only two wire connections on the opener and yet the devices use them for both power and signals. The opener was a Chamberlin 1/2 HP dating from 1994. Yours may or may not The electric eye has two small boxes -- one which sends (infrared) light, and the other which receives it. The opener is able to tell when the light beam is blocked. Each of the two boxes has a pair of wires, one white and one white with a black stripe. Those wires go in parallel to two connectors on the opener. With the devices hooked up, an oscilloscope was used to see what was goingWith the light blocked between the transmitter and receiver, the white/black wire is 6VDC above the white wire. When not blocked, a periodic signal is observed, where the white/black wire is 6V above the white wire for about 5.5 ms, then falls close to 0V for about 0.5 ms. This suggests that
the opener is supplying 6V through a resistor -- the receiver is "pulling" the voltage to (near) 0V briefly and periodically. One cannot expect it to pull too hard, so a resistor must be present. The devices were removed from the opener. With a DC voltmeter across the terminals on the opener, the voltage was measured while resistors with gradually decreasing values were put across theSince the small boxes both have lit LED's when operating, the internal equivalent resistance can't much more than about 1k for a 6V source, so that was the starting value for the external resistors. in voltage (though less than by 1/2) was noted for a couple hundred ohmsThat means that the Thevenin equivalent resistance is less than about a couple hundred ohms. A 6V power supply was wired through a 150 ohm resistor to the two boxes. Plus to the white/black wire, 0V (gnd) to the white wire. was observed to be virtually identical to what was observed from the
opener, except the maximum was closer to 5V rather than 6V. that a smaller resistor is expected or that the circuit is not linear (hence, Thevenin's theorem is not applicable). But it works, anyway. To make a completed electric eye for use without the opener, a small circuit board was used which included a 6V regulator (7806) and a 555 (low-power) wired as aThe circuitry for the latter can be found on the 555 data sheet, and is easily found with an internet search. It has been copied and recopied by many. Referring to that diagram, I used a 2N3906 PNP transistor, and a 0.1 uF capacitor and a 75k resistorThe power was supplied through a surplus wall cube (labeled 9VDC, 200 mA). The regulated 6V powers the 555 directly, and the white/black wire to the remote boxes through a series resistor (I ended up using 150 ohms for that though a somewhat smaller value may work better). I put in two LEDs. One just shows that the power is on, the other comes on when the beam
More LEDs is better, right? Pin 3 of the 555 goes low when the light beam is broken, and is highSo far it is just wired to light an LED. I am not sure what I might use the electric eye for as of yet. Perhaps something to do with trick or in the process of testing, I tried various power supply voltages. frequency of the pulses does depend on the voltage. A 5V source still seems to work, though the frequency is not as steady.

You can use a low temperature white lithium grease. Can this opener lift a 16ft wide x 12ft door Yes, this model will work but you will need to go through a professional dealer to get a one piece rail. What is the maxium weigth that it can lift ? There is no weight limit that we have for this garage door opener. We recommend that it is installed on a well-balanced garage door. what is the opening speed? The Excelerator II has an opening speed of up to 12 inches per second. I have two questions. 1. What is the difference between Excelerator and Power Max 1500? The PowerMax 1500 has a motion dector to turn the lights on and off, the Excelerator does not have this feature. The C-Channel rail will work a 7ft high garage door out of the box, the assembled length of the rail only is 112.5 inches long.
Purchased opener in January. Motor seems to whine and does not pull up door. For further assistance please contact our troubleshooting/customer service department at 1-800-354-3643. Does this come with the new rail for the ceiling? The rail that attaches to the motorhead comes in the box. The only thing additional you may need is angle iron, and the screw drive extension kit if your door is higher than 7 feet in height. Please confirm whether the product below (Genie Excelerator 1HP direct drive door opener) can be used on a 10 foot door, or if there is an extension Hello Arnie and thank you for your question. When installing the Genie Excelerator II 1500 1 HP Direct Screw Drive DC Garage Door Opener on a door that is taller than 7', you will need a Rail Extension Kit. The Home Depot sells the Genie 10 ft rail extension kit for the belt drive and chain drive units, however you will need to contact your local dealer for the custom rail kit for the screw drive garage door opener.
