TEST DISC FLAG:

When this status flag is ON, the CD200 will test for a match of the in-
coming signal pattern observed by the CD200 to the Disc Type speci-
fied. 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. Af-
ter rotation stops it will blink the appropriate signal,
Default setting = OFF.
9.6

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 cam-
shaft mounted disc. Default setting = OFF.
9.7

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 de-
grees BTDC. This value will need to be fine-tuned to provide an ac-
curate display of timing. Default setting = 40.0 degrees BTDC.
9.8

INSERTION RETARD SETTING:

This numeric entry configures the minimum internal electronic in-
put signal delay. Entry range is 2.0 to 25.5 degrees of engine retard.
Default setting = 2.0 degrees.
9.9
PURGE DELAY SETTING:
This numeric entry configures the number of disc rotations (engine
cycles) following successful synchronization to delay before ignition
outputs begin. Entry range is 0 to 255 cycles. Default setting = 0.
9.0
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 CD200 unit will blink the appropriate
code and the alarm output switch is restored to normal (closed). De-
fault setting = 2200 RPM.
