ALTRONIC CD200 IGNITION SYSTEM
9.5 TEST DISC FLAG:
 WhenthisstatusagisON,theCD200willtestforamatchofthein-
coming signal pattern observed by the CD200 to the Disc Type speci-
ed.Whenenabled,thistestisperformedaftersynchronizationto
thediscpatternandbeforeinitiatingrings.Whenthepatterndoes
not match thesetting,theignitionwillnotreand thediagnostic
LED on the unit will signaltheerror by turningoff until rotation
stops.Oncetheignitionisring,thediscpatternwillbemonitored
continuouslyand,ifanerrorisdetected,theunitwillstopring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ring,therings
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, see section 11.2.
Defaultsetting=OFF.
9.6 ON CRANK FLAG:
WhenthisstatusagisON,theignitionscalesrpmmeasurement
and timing angles for a signal pattern coming from a crankshaft-
mounteddisc.Whenthisstatusag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rstholeorprotrusiononthetimingdisc,theLineUpAngleis
the angular position of the crankshaft with respect to TDC of the
rstcylinderintheringorder.Entryrangeis0to100enginede-
greesBTDC.Thisvaluewillneedtobene-tunedtoprovideanac-
curatedisplayoftiming.Defaultsetting=40.0degreesBTDC.
9.8 INSERTION RETARD SETTING:
 Thisnumericentrycongures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congures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.
9.10 OVERSPEED SETTING:
 Thisnumericentrycongurestheenginerpmatwhichtheignition
willstopring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.
NOTE: The disc test for a
specic number of pulses is
not performed in auto detec-
tion mode (0 entry for Disc
Type Setting – section 9.4).
