Many distributors used in electronic ignition systems contain internal components and layouts
the same as the distributor described above, but are fitted with mechanical and/or vacuum
advance mechanisms which are much less effective and flexible than electronic timing as in
the E6S. If these mechanisms can be defeated or removed, and the timing edges set correctly,
then they can successfully be used to trigger the E6.
A third type of pickup, the magnetic reluctor, is used in distributors as well as on crank trigger
units. It is possible to use this type of trigger on the E6S using it’s own internal reluctor
adapter to convert the signal into the square wave required to trigger the E6S. The Primary
input is used for the main trigger, and the secondary is used for the Home(Sync. Event) or
Road Speed input.(See Syncronising Events, Appendix B2.2, B3.3 and E.3).
NOTE:
ANY COMBINATION OF HALL EFFECT, OPTICAL OR RELUCTOR
TYPE PICK-UP MAY BE USED FOR THE “TRIGGER” (MAIN IGNITION
EVENT)
AND
“HOME”
(SYNC.
EVENT)
INPUTS.
HOWEVER,
RELUCTOR TYPE PICK-UPS MUST BE CONNECTED TO THEIR
RESPECTIVE RELUCTOR ADAPTOR INPUT.
THE ONBOARD RELUCTOR ADAPTOR ACTUALLY HAS TWO
INDEPENDANT CHANNELS. ONE IS FOR THE “TRIGGER” SIGNAL.
THE SECOND IS FOR THE “HOME” SIGNAL.
EACH RELUCTOR ADAPTOR CHANNEL USED REQUIRES TWO WIRE
CONNECTIONS.
The magnetic pickup is basically a piece of wire wrapped around a magnetic core and attached
to the sensor face, which is called the pole piece. The physical size and shape of such a pickup
can take many forms. This type of pickup has either two wires (one positive (+), and the other
negative (-)), or three wires with the third being a shield. The wires are sometimes marked as
such, but more often than not they are unmarked.
If using a “reluctor” type for the TRIGGER signal input:
•
The Positive pin from the “Trigger” reluctor pick-up connects to the input of
the onboard reluctor adaptor (PIN B (TRIGGER), on the Trigger Input plug).
•
The Negative pin from the “Trigger” reluctor pick-up must connect to the
negative reluctor adaptor input (PIN D (INPUT B), on the Trigger Input
plug).
