1.0 DESCRIPTION
1.1 This manual provides installation and operating instructions for the
Altronic CD200 ignition system. It is recommended that the user
read this manual in its entirety before commencing operations.
1.2 The Altronic CD200 ignition system consists of these basic components:
•CD200 Unit - 791070-x or 791080-x (see FIG. 1 and FIG. 2)
•Magnetic Pickup Sensor (one per system)
•Input Harness (one per system)
•Output Harness (one or two 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. 3). The CD200
unit steps up the DC supply voltage to charge an en-
ergy storage capacitor and contains a microproces-
sor 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 CD200 unit. One additional hole trails
after the last cylinder hole; this is the index signal that
another revolution has started. Ignition timing may be
varied by means of a manual switch, an analog timing signal
and/or engine RPM.
1.4  TheCD200systemcanoperateasasingle-ringordouble-ring
(ringonexhauststroke)systemuptotwelve(12)cylinders.These
instructionsdetail4-,6-,8-,10-and12-cylinder,single-ringap-
plications using CD200 units 791070-6, 791070-8, 791070-12, and
791080-6, 791080-8.
1.5 As shipped from the factory, the CD200 is in the auto-detect mode
and is set up for a trigger disc running at camshaft speed (see SEC-
TION 9.4). The setup is programmable by the use of the PC compatible
CD200 terminal program (FIGS. 14 & 15) provided on a CD delivered
with the unit. The programming of the unit is done via the RS-485
Modbus compatible communications port.

storage of the ignition is
necessary, this container will
provide the optimum protection.
2.0 CD200 UNIT
2.1 Select a location for the CD200 unit that will be at least 24 inches
(600 mm) away from the ignition coils and spark plug leads. In ad-
dition, the mounting location must be relatively cool, preferably
onebenettingfromtheenginefanstream(ifany);theoutsidecase
temperature of the CD200 unit should not exceed 185°F. (85°C.) in
continuous operation.
2.2 Secure the CD200 unit to a suitable mounting bracket with four 1/4
inch (6 mm) screws. Refer to FIG. 1 or FIG. 2 for CD200 unit dimen-
sions.
3.0 PICKUP SENSOR – CAMSHAFT DISC
3.1 A disc with the appropriate hole pattern must be prepared for
mounting at CAMSHAFT speed. The disc must be of magnetic ma-
terial and 4.0" (100 mm) diameter or larger. FIG. 4 details the hole
spacing depending on the number of engine cylinders. Note the di-
rection of rotation of the disc. The angular spacing is extremely im-
portant 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. 4 for the dimensions of the 3/4"-16 pick-
up sensors.
3.3 Set the engine with no. 1 cylinder in the most advanced timing posi-
tion. Noting the direction of rotation, set the drilled disc opposite
the pickup in the position shown in FIG. 4.
3.4 Adjust the tightening nut holding the pickup sensor to maintain an
airgapasspeciedbelow:
•For magnetic pickups 791015-1 and 791016-2, the gap shall be
set to .020" ± .005" (0.50 mm ± 0.12 mm).
•For magnetic pickups 791035-2 and 791041-3 (12 mm thread),
the gap shall be set to .014" ± .004" (0.35 mm ± 0.10 mm).
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 CD200 wiring harness.
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: Some MAN engines
have a 12 mm thread port;
use Altronic pickup 791035-2
or 791041-3.

ALTRONIC CD200 IGNITION SYSTEM
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 CD200 unit
commences outputs to the ignition coils. This delay is to allow iden-
ticationofthepick-up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 9.9.
8.2 MANUAL TIMING SWITCH:
 TheCD200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OPER-
ATING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 9.14.
8.3 ANALOG TIMING ADJUSTMENT:
The CD200 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 CD200 unit is shipped with an RPM-based timing curve (de-
fault programming) providing a 6-degree advance as the engine
speed increases from 0 to 600 RPM (FIG. 12). This timing change is
in addition to changes made with the manual switch (section 8.2) or
the analog timing input (section 8.3).
NOTE: On the rst 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 shut-
down or be damaged.
NOTE: The analog timing
retard is added to the retard
established by the manual
timing switch (see section
8.2 above and FIG.12).
NOTE: When checked at
different speeds, timing will
vary in accordance with the
programmed RPM curve
indicated.

INSTALLATION INSTRUCTIONS
9.0 CUSTOMIZING THE CD200 UNIT
9.1
TERMINAL PROGRAM SETUP:
The CD200 is designed to be programmed by a Personal Computer
via the RS-485 Modbus communications link. See FIG. 13 for the
proper hookup. The CD200 unit case must be securely grounded
prior to programming.
The Terminal Program is included on the CD-ROM supplied with
eachCD200unit.Thersttimethattheterminalsoftwareisused
onaPC,theCommunicationsPortsettingsmustbeconguredin
order to establish communications. After loading the Terminal Pro-
gram 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 CD200 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 CD200. Set the ID# for the
CD200 to 01.
9.2 PROGRAMMING CUSTOM VALUES:
A variety of numeric parameters can be entered by the user for cus-
tomized 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typinginthenewvalue.Whenthenew
numericvalueisrsttyped,itappearsinredtextonthePCscreen.
The values appearing in red have not yet been sent to the CD200
unit, but are being stored on the PC until being sent. Hitting the
EnterkeysendstheselectiontotheCD200.Theenteredvalueturns
green on the PC display, indicating that the new value has been suc-
cessfully communicated to the CD200 and stored.
9.3 SELECTING OPTIONAL FEATURES:
Other OFF/ON programming selections are made by activating or de-
activatingabluestatusagonthePCscreen.Whenthemousepoint-
erislocatedoverthestatusag,adouble-leftclickactivatesthestatus
agandmakesitappeartobe“ON”orglowingonthePCscreen,a
double-rightclickdeactivatesthefeatureandthestatusag.
9.4 DISC TYPE SETTING:
 Thisnumericentry congures 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 cam-
shaft mounted disc and ½ the number of cylinders of the engine for
a crankshaft mounted disc. This value is used to test for the correct
disc and scales the rpm measurement and ignition timing angles to
thespecic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.
NOTE: In order to program the
values, the CD200 must be
powered. Care should be tak-
en in changing entries when
the engine is operational to
avoid unstable or dangerous
operating conditions.
NOTE: Refer to sections 9.19
and 9.20 for additional pro-
gramming of unit 791070-12.
