Function - 2. Fitting - 3. Electrical connection - 4.Adjustment - 5. General The digital ignition ZDG3 consists of following components: - light-barrier printed circuit board - corresponding mechanical components - the ignition box and replaces contact breaker plate and advance unit. Function: per revolution of the crankshaft starting from TDC, the momentary peripheral speed is determined and by this means, the time up to ignition is calculated. Because the peripheral speed varies substantially during acceleration, this long measurement is selected in order to determine a relatively exact measurement. The following computation of ignition timing is divided into 4 ranges: 1. 0-400 rpm 2. 400-1000 rpm 3. 1000-6200 rpm 4. 6200-10000 rpm Starting range, ignition always at TDC Idling range, 2° to 8° advanced ignition, depending on curve selection Partial load range, the spark advance adjustment occurs here maximum load range, constant 30° to 39° advanced ignition, depending on curve selection As opposed to the original ignition system, ignition now takes place at each revolution of the crankshaft, thus also during the exhaust stroke. ignition box pulse disc and light-barrier printed circuit board The measuring happens by opto-electronic parts - light barriers - because only light barriers produces an always same, speed-independent precise signal and therefore all computations can be made more accurately. If the engine stops, the ignition current will be switched off after 3 sec. to protect the ignition coils. 9 ignition curves are available: Fitting instructions digital ignition ZDG3 for Aermacchi 1. Function - 2. Fitting - 3. Electrical connection - 4. Adjustment - 5. General Remove the contact breaker plate and the mechanical advance unit and fit the driver. Then fasten the printed circuit board. Finally put the lightdisk onto the driver but don't tight the set-screws yet. The attachment of the ignition box takes place by the provided velcro strip on a suitable surface, which should not be in the splash-water range. The original ignition coil can be used further. In case of an exchange nearly all types of new or used ignition coils can be used, which corresponds to a primary resistance of 2.5 - 6 Ohms.

The conductor cross-section of the earth cable should amount to 1,5-2,5 mm2 and schould be kept as short as possible. The conductor cross-section of the other cables should not be below 0,75 mm2. Always use end splices! 0 Fitting instructions for digital ignition ZDG3 (Aermacchi 350) 1. Function - 2. Fitting - 3. Electrical connections - 4. Adjustments - 5. General Attention! Remove the spark plug caps before adjusting the light disc! First the piston must be brought on TDC. Now rotate the light disk precisely into position as shown in the picture. The position is correct when the LED (yellow circle) toggles. Now tighten the grub screws evenly (ensure that the light disk is in the centre of the light-barrier!) and push the spark plug caps. The bike is ready to start. The switches can be found at the front of the ignition box: switch adjustment rotary switch dip switch (curve selectionl) overspeed protection at 7900 rpm 1-9 curves 1-9 1 (switch down) or at 9800 rpm (switch up) rev. counter frequency 0 test mode, continuous firing 2 (switch up >> fout =crankshaft switch down >> fout=camshaft ) Fitting instructions for digital ignition ZDG3 (Aermacchi 350) 1. Function - 2.Fitting - 3. Electrical connection - 4. Adjustment - 5. General Only use an interference-free cap for the spark plug! (recommended NGK caps with 5kOhm internal resistance) Malfunction sources : Unstable ignition timing : At some stroboscope lamps the ignition point suddenly oscillates around 4-6°. In this case the lamp once reacts to the ignition spark starting, another time to the burning end of the spark. If possible readjust the sensitivity of the lamp. Doesn't start : You can check the function of the ignition by unscrewing the spark plugs, leaving them in the plugs, connect to ground and by slowly kicking you can see or hear the sparks. To check the cable connecting and the supply voltage put the rotary switch to '0'. Now the spark plugs must fire continually. Irregular engine cutouts: If sometimes the engine suspends while driving for 2-3 seconds and keeps running thereafter completely normally that means that the ignition has been reset. The cause for it can be a defective cap or a loose ignition cable in the coil or cap. But in most cases a bad contact in the operating voltage supply (starter lock, fuse holder etc.) causes tis effect. For a test you can put a cable directly from the ignition coils and the ignition box to the positive terminal of the battery. Also put a second cable from the negative terminal of the battery to the ignition box (secure ground connection). If the engine is running well now you can assume an error in the wiring harness. With contact brakers such a bad contact is not noticeable, because a short break for a few milliseconds of the supply voltage does't matter, electronics in contrast are more sensitively.
