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).
