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.
