The Push-button Inputs
The buttons are used to start all timing sequences of
the Mega 475. There are four push-button inputs, labeled
P.B. 1, P.B. 2, Tap P.B., and L.L. P.B. The P.B. 1 terminal
is the primary button input and must be connected, for the
Mega 475 to work.
Most buttons have more than one purpose, the
Additional Button Functions Chart on page 55 shows the
primary function along with any other functions for each of
the buttons.
What the primary, second, and third function of each
button is, depends on whether the Mega 475 is in Bracket or
Pro Mode and what the Push-button Mode is. Each button is
listed below individually to explain their functions
depending on these conditions.
Button 1 Functions
Note:
P.B. Mode 1 – 4 start timing on the release of the
button. P.B. 5 is the opposite and starts timing on the press
of the button
.
When in Bracket Mode
P.B. Mode Set to 1
This is the most commonly used setting. Press the
button down when staging the vehicle, and then release the
button, usually on the top yellow light. When the button is
released the Mega 475 will start counting down the
Crossover/Delay 1 time.
If the button is pressed again the countdown is
terminated. Then when the button is then released again the
Mega 475 will start counting down the full Crossover/Delay
1 time again. This is helpful if the driver flinches (lets go of
the button before the top yellow comes on).
