Operational System Details
Sensing sequence: The AS7 upon power up of the circuit (red wire and black wire) checks the trigger wire (yellow wire) for 1 second to to detect 12V+. If yellow wire gets powered up within 1 second AS7 determines this to be a BMW CAN-BUS circuit while ignoring digital info on the line. If it does NOT get powered up then AS7 determines it to be a standard vehicle which will later apply +12V pulse there for activation. A pre-CAN-BUS BMW bike (aprox 1994-2004) will also not apply any voltage to the yellow wire. The yellow wire on this older BMW bike sees a floating open line, and this require installer to connect the 2 short blue wires on AS7 together.
User Program Change
Program change 1 or 2 pulses activation: The AS7 normally is packaged with the processor programmed for 1 pulse. This means trigger is activated for over 1.2 second then LED flashes and trigger is released during the fast flash of the LED. LED changes from red to green to indicate state. The AS7 is easy to program so it uses 2-quick-pulses for activation. The 2 quick pulses have to be less than 1 second apart and again, during LED flashing. To Change Program: Simply hold the trigger (yellow wire) to +12V Or Ground/open line, depending on your vehicle set up, for 40 seconds solid. After the 40 seconds the LED starts flashing quickly now at this time pulse the trigger wire (remove the 12V+ OR ground) a few times, and LED will go green for 1 second to indicate success. These directions are on the instruction sheet however saying to use the trigger button already connected to the yellow wire.
Using a Headlight Modulator
This Autoswitch is triggered by the high beam wire so there is no interaction because your modulator affects only low beam. However our instructions may tell you to feed power to the Autoswitch (to energize the circuit) from the low beam wire or power source. Thats only one of the sources available to you for this purpose. If you do select that wire to energize the AS, just be sure feed point is BEFORE the modulator so the AS gets steady power.
Using a Turn Signal Canceler
If using an aftermarket turn signal canceler that ALSO sends a negative or ground connection to the controller box, be sure the pulse is less than 1 second in length and it is a single pulse. This will avoid it telling the Autoswitch to activate your lights relay ON or OFF. Or activating the garage door opener.
Using Multiple Autoswitches on the Same Vehicle
The AS7 is user programmable after installation or at any time while it is powered up. In our old AS5 series we had single and dual pulse models. The AS7 can be programmed using pulse sequences and watching the LED to become a single 1.2 second pulse OR the 2-quick-pulses version, old AS5P2.
The single pulse AS7 sense wire looks at a high-beam ON window of 1.2 seconds to 10 seconds during which time the high beam would be turned off to activate your lights relay.
The second Autoswitch programmed for 2 quick pulses, takes 2 quick power on pulses from the high beam wire to activate the lights relay. This AS7 ignores the long pulse that's seen only by the other AS7. Likewise the other AS7 ignores the 2 quick pulses that this AS7 sees. The garage remote Autoswitch (AS7G avail April) can be also user programmed to avoid "seeing" a command for one of the AS7 explained above. Some uses for 2 switches might be separate control of one or 2 sets of auxiliary lights. Or to turn on a power strip providing power direct from the battery, or to remove power from a circuit.
On BMW bikes with the negative pulse turn signal cancel, up to 4 switches total can be used! Two controlled by the turn signal cancel button and 2 more from a high beam wire.
LED Indicator Light Information
The LED shines steady RED when the AS7 has no voltage on the relay activation violet wire. The LED shines steady GREEN when the violet wire is active with 12V which would activate your lights relay.
This LED has a lens on top. The housing is a 5mm diameter, 7mm tall. There is a 1mm long flange at the bottom thats 6mm diameter. The wire underneath needs aproximately 20mm before a full bend can be made. This stiffness is only due to all the layers of protective heat shrink tubing. By modifying this area the bottom of the LED wire secion can be set up much smaller.
The LED is a bi-color. Red or Green. It changes color by getting the volatge on the feed wire reversed by the processor. When the LED is quickly pulsed the color appears orange to the eye. The wire is 6 to 7 feet long. It should never be cut or altered due to the danger of damaging the processor chip. If the wires are shorted when the Autoswitch is powered up, the processor chip will be instantly ruined.
Further tech info about converting the LED to be a bulb, or changing to a different LED entails custom work, info and configurations we do not have available at this time.
Replacement LED Bulbs
The AS7 uses a Kingbright L-57EGW 5mm Red/Green LED Bi-color bulb. Replacements can be purchased at www.rapidonline.com or any other on-line or brick and mortar stores that carry Kingbright products. See item data sheet to help determine what other equivalents will work.
