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.
WARNING: DEVIATION FROM THESE
INSTRUCTIONS MAY LEAD TO IM-
PROPER OPERATION OF THE MACHINE
WHICH COULD CAUSE PERSONAL
INJURY TO OPERATORS OR OTHER
NEARBY PERSONNEL.

3.3 Set the engine with no. 1 cylinder in the most advanced timing position. Not-
ing the direction of rotation, set the drilled disc opposite the pickup in the
position shown in FIG. 3. Some 12- and 16-cyclinder engines may require line
up on a different cylinder, typically the second cylinder in the firing order.
3.4 Adjust the tightening nut holding the pickup sensor to maintain an air gap as
specified below:
■For 3/4" magnetic pickups 791015-1 and 791016-2, the gap shall
be set to .020" ± .005" (0.50mm ± 0.12mm).
■For magnetic pickups 791035-2 and 791041-3 (12mm thread),
the gap shall be set to .014" ± .004" (0.35mm ± 0.10mm).
The center of the pickup face must line up with the center of each drilled hole
as the disc rotates.
3.5 Plug the 2-pin pickup connector fully into the mating connector of the
CD200D wiring harness.
3.6 ALTERNATIVE HALL EFFECT Pickup AND MAGNET DISC – On 4-cycle
engines, the disc mounts to the camshaft or other shaft operating at one-half
engine speed. On 2-cycle engines, the disc mounts to the engine crankshaft.
3.7 Set the engine with no. 1 cylinder 2.0 crankshaft degrees, 4-cycle or 1.0
degree, 2-cycle ahead of the most advanced desired timing point on the
compression stroke. This is the point where the Hall-effect pickup must line-
up with the edge of the magnet next to the “x” on the O.D. of the disc. When
mounting the magnet disc, be sure to observe the rotation indication marked
on the disc.
3.8 Mount the Hall-effect pickup sensor, FIG. 4, securely to a rigid bracket or
surface to maintain an air gap not exceeding .040" (1.0mm). The center of the
pickup face must also line up with the center of the disc as it rotates.
3.9 Plug the cable for the pickup into the 6-pin connector of the CD200D unit;
the 3-pin connector end plugs into the Hall-effect pickup.
4.0 IGNITION COILS
4.1 USE ONLY THE ALTRONIC COILS INDICATED HERE:
■UNSHIELDED: 501061, 591010, 591040
■FLANGE: 591012, 591018
■SHIELDED: 501061-S, 591010-S
■INTEGRAL: 591007, 591011A, 591011B
4.2 Mount the ignition coils as close to the spark plugs as possible keeping the
high-tension lead length to a minimum but also keeping temperatures below
200°F. (95°C.) during operation.
NOTE: Keep the pickup
sensor wires at least 2" (50 mm)
away from the coil primary wires and
at least 8" (200 mm) away from the
spark plug leads.
NOTE: On certain 12- and 16-cylinder
engines, a cylinder other than no. 1
(typically the second cylinder in the
firing order) must be used when lining
up the disc and pickup.

5.0 PRIMARY WIRING
5.1 The CD200D system requires a battery or other DC power source providing
12-30Vdc for running and a minimum of 8 volts for engine starting. Refer to
FIG. 2 for details of the connection to the DC power source.
5.2 Primary wiring hookup is shown in the wiring diagram template – FIGS. 5 or 6.

The common coil ground lead on all units is the J harness lead.
5.3 All connections at unshielded coils should be made using ring-type terminals
specified for 16 AWG (1.5 sq. mm) wire and #10 (5mm) stud size. Terminals
should either be soldered to the wire or attached with an appropriate staking
tool. Protect primary wiring from physical damage, vibration and temperatures
in excess of 200°F. (95°C.).
5.4 For details of the hookup for the analog timing signal, see FIG. 7.
6.0 SHUTDOWN WIRING
6.1 The CD200D system is shut-off by interrupting the DC power to the unit; use
a switch or relay with contacts rated 24Vdc, 10 amps - refer to FIG. 2.
6.2 The CD200D can also be shutdown by using the G-lead of the output harness.
To shutdown the unit, connect the G-lead of the output harness to ground. The
CD200D will draw about 0.1 ampere from the power source when shutdown,
see FIG. 5 or 6.
7.0 SECONDARY WIRING
7.1 With unshielded coils, spark plug leads should be fabricated from 7mm, silicone
insulated, ignition cable with suitable terminals and silicone spark plug boot.
7.2 Keep spark plug leads as short as possible and at least 2" (50mm) away
from any grounded engine part. In deep spark plug wells, use rigid, insulated
extenders projecting out of the well.
7.3 The use of a clear, silicone grease (such as Dow Corning DC-4, G.E. G-623
or GC Electronics Z5) is recommended for all high-tension connections and
boots. This material helps seal out moisture and prevent corrosion from atmo-
spheric sources.
WARNING: THE HOOKUP SHOWN IS
FOR THE MOST COMMON ENGINE FIR-
ING ORDER. CONNECT TO THE IGNITION
COILS ACCORDING TO THE ACTUAL
ENGINE FIRING ORDER.
See section 9.21 for details on
programming the slave firing angle and
for special wiring instructions.
NOTE: Keep the primary wiring at least
2" (50mm) away from the spark plug
leads.
NOTE: Do NOT run the input power line
through a series of normally closed
switches.
NOTE: The CD200D should not be
used to power ignition-powered panel
instruments.
NOTE: The use of resistance spark
plug cable or individual 5,000 ohm
resistors (mounted either at the spark
plug or coil) is recommended.

8.0 OPERATION
8.1 IGNITION DELAY:
On cranking, there will be a delay of two disc revolutions—after the power is ON
and the engine begins rotating—before the CD200D unit commences outputs to
the ignition coils. This delay is to allow identification of the pickup index hole to
insure proper synchronization with the engine. A greater delay of more revolutions
to allow for engine purging can be added to the programming. See section 9.10.
8.2 MANUAL TIMING SWITCH:
The CD200D unit has a TIMING switch located under a white plastic cap at
the end of the case. Using a timing light, set the timing to the desired position
with the engine running at NORMAL OPERATING SPEED. Replace the white
cap over the timing switch once the proper timing is set. Switch position 7
gives the most advanced timing. The timing retards approximately one (1)
engine degree for each switch position as the switch is moved to position 6, 5,
4, 3, 2, 1, 0. Switch position 0 is full retard. Larger timing changes per switch
position can be programmed. See section 9.15.
8.3 ANALOG TIMING ADJUSTMENT: (REFER TO FIG. 7)
The CD200D unit provides for analog timing adjustment in two ways:
■0-1,000 ohm potentiometer connected between terminals E
and F of the input harness.
■4-20 mA signal applied to leads F and G of the input harness.
8.4 RPM BASED TIMING CURVE:
The CD200D unit is shipped with an RPM-based timing curve (default pro-
gramming) providing a 6-degree advance as the engine speed increases from
0 to 600 RPM (FIG. 7). This timing change is in addition to changes made
with the manual switch (section 8.2) or the analog timing input (section 8.3).
9.0 CUSTOMIZING THE CD200D UNIT
9.1 TERMINAL PROGRAM SETUP:
The CD200D is designed to be programmed by a Personal Computer via the
RS-485 Modbus communications link. See FIG. 8 for the proper hookup. The
CD200D unit case must be securely grounded prior to programming.
The Terminal Program is included on the CD-ROM supplied with each CD200D
unit. The first time that the terminal software is used on a PC, the Communica-
tions Port settings must be configured in order to establish communications.
After loading the Terminal Program from the CD-ROM, click on the Connection
icon on the upper tool bar. The Connection Setup window will appear. The port
being selected for use with the CD200D should also be set for 9600 baud, no
parity, 200 ms time out (8 data bits and 1 stop bit). The PC will now be set to
communicate with the CD200D. Set the ID# for the CD200D to 01.
9.2 PROGRAMMING CUSTOM VALUES:
A variety of numeric parameters can be entered by the user for customized
applications or the unit can be left at the factory default settings. Changes to
numeric values are made by placing the cursor in the appropriate box and typ-
ing in the new value. When the new numeric value is first typed, it appears in
red text on the PC screen. The values appearing in red have not yet been sent
to the CD200D unit, but are being stored on the PC until being sent. Hitting
the Enter key sends the selection to the CD200D. The entered value turns
green on the PC display, indicating that the new value has been successfully
communicated to the CD200D and stored.
9.3 SELECTING OPTIONAL FEATURES:
Other OFF/ON programming selections are made by activating or deactivating
a blue status flag on the PC screen. When the mouse pointer is located over
the status flag, a double-left click activates the status flag and makes it ap-
pear to be “ON” or glowing on the PC screen, a double-right click deactivates
the feature and the status flag.
NOTE: On the first start-up after system
installation, verify correct ignition
timing by cranking the engine with the
fuel supply shut off.
NOTE: DO NOT switch from position
7 to 0, or 0 to 7 while the engine is
running. The large timing change may
cause the engine to shutdown or be
damaged.
NOTE: The analog timing retard is
added to the retard established by the
manual timing switch (see section 8.2
and FIG. 9).
NOTE: When checked at different
speeds, timing will vary in accordance
with the programmed RPM curve
indicated.
NOTE: In order to program the values,
the CD200D must be powered. Care
should be taken in changing entries
when the engine is operational to
avoid unstable or dangerous operating
conditions.

9.4 Pickup TYPE SELECTION:
OFF/ON programming selection to enable the use of a Hall-effect pickup.
Requires proper harness.
9.5 DISC TYPE SETTING:
This numeric entry configures the Disc Type (number of holes or protrusions)
on the timing disc, excluding the index. This number is normally equal to the
number of cylinders on the engine for a camshaft mounted disc when the
engine is even firing, and half the number of cylinders when it is odd-firing
and requires the programming of a “slave angle”. 4-cycle crankshaft mounted
discs or holes in a flywheel can only be used on even firing applications and
cannot be used with “slave angles”. This value is used to test for the correct
disc and scales the rpm measurement and ignition timing angles to the spe-
cific disc chosen. Default setting = (0+1).
Entering a value of Zero (0+1), places the ignition in auto detect mode. In
auto detect mode, the ignition will automatically scale rpm measurement and
ignition timing angles to the disc pattern observed.
9.6 Test Disc Flag:
When this status flag is ON, the CD200D will test for a match of the incom-
ing signal pattern observed by the CD200D to the Disc Type specified. When
enabled, this test is performed after synchronization to the disc pattern and
before initiating firings. When the pattern does not match the setting, the
ignition will not fire and the diagnostic LED on the unit will signal the error by
turning off until rotation stops. Once the ignition is firing, the disc pattern will
be monitored continuously and, if an error is detected, the unit will stop firing
and the alarm output switch will open. Firings will be inhibited and the output
switch will remain off for 5 seconds after input signals cease.
If the shutdown lead is grounded after the unit is firing, the firings will stop, the
output switch will open and remain open for 5 seconds after rotation stops.
The diagnostic LED on the unit will turn off until rotation stops. After rotation
stops it will blink the appropriate signal, see section 11.2. Default setting = OFF.
9.7 On Crank Flag:
When this status flag is ON, the ignition scales rpm measurement and timing
angles for a signal pattern coming from a crankshaft-mounted disc. When this
status flag is OFF, the ignition scales rpm measurement and timing angles for
a signal pattern from a camshaft mounted disc. Default setting = OFF.
9.8 Line Up Angle:
This numeric entry has no impact on actual engine timing and is only used as
a reference to calculate the spark timing number for display in the Terminal
Software. When the pickup is aligned with the first hole or protrusion on the
timing disc, the Line Up Angle is the angular position of the crankshaft with
respect to TDC of the first cylinder in the firing order. Entry range is 0 to 100
engine degrees BTDC. This value will need to be fine-tuned to provide an ac-
curate display of timing. Default setting = 40.0 degrees BTDC.
9.9 Insertion Retard Setting:
This numeric entry configures the minimum internal electronic input signal
delay. Entry range is 2.0 to 25.5 degrees of engine retard. Default setting =
2.0 degrees.
9.10 Purge Delay Setting:
This numeric entry configures the number of disc rotations (engine cycles) fol-
lowing successful synchronization to delay before ignition outputs begin. Entry
range is 0 to 255 cycles. Default setting = 0.
9.11 Overspeed Setting:
This numeric entry configures the engine rpm at which the ignition will stop
firing outputs due to an overspeed condition. The overspeed condition also
turns off the alarm output switch. When rotation has fully stopped, the LED on
the CD200D unit will blink the appropriate code and the alarm output switch
is restored to normal (closed). Default setting = 2200 RPM.
NOTE: Pickup type selection is critical
and must be properly configured to
match the pickup type in use.
NOTE: Conversion from some DISN
applications will require a new disc
with half the number of cylinders if
slave angles are required!
NOTE: The disc test for a specific
number of pulses is not performed in
auto detection mode (0 entry for Disc
Type Setting – section 9.5).

9.12 Run Speed Setting:
This numeric entry configures the transition speed from crank to run. This set-
ting also determines the transition of the diagnostic LED on the CD200D from
crank to run modes. Default setting = 500 RPM.
9.13 Low Voltage Setting:
This numeric entry configures the threshold for the low voltage diagnostic of
the DC input voltage to the CD200D. If the DC voltage decreases to this set-
ting, the diagnostic LED on the CD200D will blink the appropriate code. The
CD200D will continue to try to fire outputs regardless of the voltage. Default
setting = 6 volts.
9.14 Enable LED Diagnostics Flag:
When this LED status flag is activated, the blink code diagnostics for primary
and secondary outputs are enabled. Default setting is ON.
9.15 Switch CAL:
These numeric entries configure the timing retard for each position of the
manual timing switch on the CD200D case. Entry range is 0 to 25.5 degrees
of engine retard. The active entry is indicated in blue. Default setting is 7-6-5-
4-3-2-1. If two degrees change per switch position is desired, enter 14-12-10-
8-6-4-2.
9.16 Loop CAL:
These numeric entries configure the interpolated lookup table for the ignition
retard versus the analog current loop input signal. This allows the operator to
create custom spark timing maps versus the current loop input signal. Entry
range is 0 to 25.5 degrees of engine retard. The active entries are indicated
in blue. Default sequence is 0 degrees retard at 4mA, 16 degrees retard at
20mA.
9.17 RPM CAL:
These numeric entries configure the interpolated lookup table for retard versus
the engine speed. This allows the operator to create custom spark timing maps
versus engine rpm. Entry range is 0 to 25.5 degrees of engine retard. The
active entries are indicated in blue. Default sequence is 6 degrees retard at 0
RPM, decreasing to 0 degrees retard at 600 RPM.
9.18 Enable Slave Firing Flag:
When this LED status flag is activated, the ignition will generate a second
slave firing for each (x+1) reference pulse. For a (6+1) disc pattern, the igni-
tion will fire 12 outputs when this flag is activated, and 6 outputs when this
flag is not activated. Modification of this flag through the Terminal Program
requires that the engine be stopped and the G-lead be grounded.
9.19 SLAVE FIRING ANGLE SETTING:
This numeric entry configures the angle of the slave firing relative to the stan-
dard firings that are generated for each (x+1) reference pulse. Entry range is
25.0° to 60.0° which is used to set the slave firing angle on a 12 or 16-cylin-
der, 4-cycle engine. The slave angle must be the smaller of the two angles that
define the engine firing pattern. For example, firing patterns of either 30°–60°
or 60°–30° would require the slave angle be entered as “30”. Modification of
this value through the Terminal Program requires that the engine be stopped
and the G1 lead be grounded.

9.20 Cylinder CAL:
These numeric entries configure the amount of individual offset timing retard
added to the global timing for each individual output. This feature can be used
to map an evenly spaced timing disc to an odd firing angle engine pattern. En-
try range is 0 to 50 degrees of engine retard. Default settings are 0. Contact
the factory for further details of this feature.

Default setting is 160 volts at the capacitor. This voltage can only be mea-
sured using a device with an input impedance of 1 megaohm or higher with no
other device connected.
10.0 PC TERMINAL DISPLAY FUNCTIONS
10.1 Engine Speed:
Indicates current speed of the engine in RPM based on disc signal.
10.2 Spark Timing:
Indicates the global spark timing of the engine in degrees before TDC. This
number is the LINE UP ANGLE setting less the TOTAL RETARD. Slight dif-
ferences between this number and the timing reading obtained with a timing
light may occur since the LINE UP ANGLE entered may differ slightly from the
actual angular position of the engine when the input pulse event is received by
the CD200D. In this event, the Spark Timing number should be made to agree
with the timing light by changing the LINE UP ANGLE entry.
10.3 Switch Position:
Indicates the current position of the manual timing switch on the CD200D case.
10.4 Loop Input:
Indicates the value of the external input current loop.
10.5 Observed Disc:
Indicates the number of input events (timing holes, protrusions or magnets) be-
ing recognized by the CD200D unit on the timing disc input signal at this time.

10.43 Graphic Display:
The CD200D Terminal Software provides a real time graphic display of the
secondary diagnostic numbers, global engine timing (y-axis/10) and engine
speed (y-axis x 10).
11.0 CD200D UNIT LED DIAGNOSTIC BLINK CODES
11.1 CD200D IGNITION BLINK CODES:
Whenever the LED Diags status flag is enabled (blue) by using the CD200D
Terminal Software, the blinking pattern of the LED on the side of the CD200D
case can be used to interpret the general status of the CD200D diagnostics
without the use of the Terminal Software. Within each group of conditions
described below, the possible diagnostic states are listed according to their
number of blinks. The LED is ON for about 2 seconds between each blink
sequence and the blinks occur evenly spaced at a faster rate.
11.2 LED SIGNALS WITH THE ENGINE STOPPED:
ON – Steady = READY (new power up or last start attempt aborted)
ON – 1 Blink – ON = FIRED LAST TIME ROTATING (stopped due to stall)
ON – 2 Blink – ON = SHUTDOWN (By grounding G-LEAD when running)
ON – 3 Blink – ON = SHUTDOWN (By Remote Serial Request when running)
ON – 4 Blink – ON = SHUTDOWN (By Overspeed when running)
ON – 5 Blink – ON = WRONG DISK PATTERN
ON – 6 Blink – ON = LOW SUPPLY VOLTAGE (Below Threshold when running)
11.3 LED SIGNALS WITH ENGINE CRANKING:
Rotating, and still below running RPM.
ON/OFF/ON/OFF = PURGING (off first input pulse, toggles each revolution of purge)
ON – Steady = FIRING NORMALLY (RPM below running set point value)
OFF = WRONG DISC PATTERN DETECTED
11.4 LED SIGNALS WITH ENGINE RUNNING:
When firing, and above run speed.
ON – Steady = FIRING NORMALLY (No Diagnostics to Report)
ON – 1 Blink – ON = OPEN SECONDARY ALARM
ON – 2 Blink – ON = PRIMARY SHORT ALARM
ON – 3 Blink – ON = PRIMARY OPEN ALARM
ON – 4 Blink – ON = NO CHARGE ALARM
ON – 6 Blink – ON = LOW SUPPLY VOLTAGE
