13
½ second) that ends with WHITE, followed by either RED or GREEN, and then transition to
normal color signals. RED engines will look for a white/RED color burst. GREEN engines will
look for a white/GREEN color burst. Turn bus power OFF.
a) If the DIR Color-Burst matches your engine - proceed to Step 3. If
it doesn’t - change DIR –
see Note 1 below.
3)
TC Setpoint:
Storing ignition TC Setpoint first entails moving the engine to its TC position.
Other methods
(Note 1)
can be used, but we recommend the procedure below.
If using other
methods, do so now and skip steps a) and b) ii, iii, iv [*keep b)i) and b)v)].
Otherwise, locate
and store ignition TC as follows (TC Locator mode):
a) Remove spark plugs from Bank A cylinders #1 and #2.
Engine movement will be easier and
safer if you also remove one plug from each of the other cylinders.
Move the engine so
piston #1 is near bottom of the stroke.
No need to track #1 compression
– either stroke will
work
. Insert the threaded piston stop tool in either plug hole of cylinder #1.
b) Verify bus power and Kill Switches are both OFF.
i)
*Enter TC Locator mode
: Press and hold the Config Button while you turn bus power
ON. Continue hold (roughly six seconds) until LED turns BLUE - then release. The LED
will turn BLUE with a periodic GREEN pulse, confirming you are now in TC Locator
mode where the following interactions are enabled.
ii) Slowly rotate the prop in either direction until the piston gently contacts the stop (first
stop). Quick-press the Button and the LED will switch to GREEN with a periodic BLUE
pulse.
iii) Slowly rotate prop in the other direction until the piston gently contacts the stop (second
stop). Quick-press the Button and the LED will switch to steady GREEN, indicating the
ignition has calculated the TC (and 180-degree) positions. Keep bus power ON.
iv) Remove the stop tool.
Backing the prop (piston) away from the stop will make it easier
to unscrew.
Then continue prop movement in the last (second stop) direction. The LED
will turn RED and sound tone (RED/tone) when you arrive at engine TC position.
v)
*SET TC:
Press/hold the Button for six (6) seconds and the LED will flash WHITE -
release button. TC is now stored, and the ignition will automatically re-boot in normal
mode. The LED will settle at steady YELLOW (with tone), indicating the ignition is at the
stored TC position.
Note 1
: Other methods to locate TC include the manufacturers “flower pot” method or move engine
to match TC of a previously set E-MAG on the other side.
4)
MIN (BLUE) and MAX (WHITE) setpoints:
a) Check setpoints by positioning prop (engine) to the MIN and then the MAX positions.
Approaching setpoint positions with engine moving in the normal direction may help to
reduce gear lash
i)
Confirm the MIN(BLUE) setpoint matches the engine manufacturers recommended
magneto firing angle.
NOTE: Engine alterations that boost power (high-compression
pistons, induction mods, custom cams, enhanced fuels, etc. may require more
conservative (lower) MIN and MAX settings. The ignition default MIN is around 20 to
22-degrees before TC. Adjust as needed.
ii) MAX(WHITE)
The ignition default MAX is 9-degrees ahead of MIN and can be re-set as
low as 6-degrees ahead of MIN.
