1.0 DESCRIPTION
1.1 This manual provides installation and operating instructions for the Altronic
CD200D ignition system. It is recommended that the user read this manual in
its entirety before commencing operations.
1.2 The Altronic CD200D ignition system consists of these basic components:
■
CD200D Unit - 791090-x or CD200D Unit - 791090-xR (See FIG. 1)
■
Magnetic Pickup Sensor or Hall-effect pickup (one per system)
■
Input Harness (one per system, specific to pickup type)
■
Output Harness (one per system)
■
Ignition coils (one per cylinder)
1.3 The system requires a battery or a suitable power supply with a nominal 12 Vdc
or 24 Vdc (see FIG. 2). The CD200D unit steps up the DC supply voltage
to charge an energy storage capacitor and contains a microprocessor and
solid-state switching devices to release the stored energy to the ignition coils
in programmed, timed sequence according to the application. Holes (one per
cylinder) in a special timing disc signal the position of the engine crankshaft to
the electronic circuitry in the CD200D unit. One additional hole trails after the
last cylinder hole; this is the index signal that another revolution has started.
An Altronic manufactured magnet disc should be used when employing a Hall-
effect pickup. Ignition timing may be varied by means of a manual switch, an
analog timing signal and/or engine RPM.
1.4 The CD200D system can operate as a single-firing or double-firing (firing on ex-
haust stroke) system up to sixteen (16) cylinders. These instructions detail 8-,
12-, and 16-cylinder, single-firing applications using CD200D units 791090-8,
791090-12, 791090-16, 791090-8R, 791090-12R, 791090-16R.
1.5 As shipped from the factory, the CD200D is in the auto-detect mode and is set
up for a trigger disc running at camshaft speed (see SECTION 9.5). The setup is
programmable by the use of the PC compatible CD200D terminal program (see
FIG. 9) provided on a CD delivered with the unit. The programming of the unit is
done via the RS-485 Modbus compatible communications port.
2.0 CD200D UNIT
2.1 Select a location for the CD200D unit that will be at least 24 inches (600mm)
away from the ignition coils and spark plug leads. In addition, the mounting
location must be relatively cool, preferably one benefitting from the engine fan
stream (if any); the outside case temperature of the CD200D unit should not
exceed 185°F. (85°C.) in continuous operation.
2.2 Secure the CD200D unit to a suitable mounting bracket with four ¼-inch
(6 mm) screws. Refer to FIG. 1 for CD200D unit dimensions.
3.0 PICKUP SENSOR – CAMSHAFT DISC
3.1 MAGNETIC Pickup – A disc with the appropriate hole pattern must be
prepared for mounting at CAMSHAFT speed. The disc must be of magnetic
material and 4.0" (100mm) diameter or larger. FIG. 3 details the hole spacing
depending on the number of engine cylinders. Note the direction of rotation
of the disc. The angular spacing is extremely important as this establishes the
basic timing accuracy of the system.
3.2 Locate a suitable mounting position for the pickup sensor in order to sense the
holes in the rotating disc. Secure the pickup to a rigid bracket or surface. See
FIG. 3 for the dimensions of the ¾"-16 pickup sensors.
NOTE: If possible, keep the original
shipping container. If future
transportation or storage is necessary,
this container will provide the
optimum protection.
NOTE: Please see Addendum CD200D
R II 4-17 for instruction details when
using CD200D units 791090-8R,
791090-12R, 791090-16R.
NOTE: Some MAN engines have a
12 mm thread port; use Altronic
pickup 791041-3.
