S.F.O. Mode
S.F.O. stands for Selectable Function Output. This
mode is used to control what the function of the S.F.O.
output is. There are five different S.F.O. modes (1-5) listed
below.
1) S.F.O. Mode 1 – Sets the S.F.O. output terminal to
function as a Starting Line Enhancer (S.L.E.).
This is the most commonly used mode.
2) S.F.O. Mode 2 – Sets the S.F.O. output terminal to
function as the second 4 Stage Timer (T2). Only
when the S.F.O. mode is set to 2 will the Timer 2
screen be available.
3) S.F.O. Mode 3 – Sets the S.F.O. output terminal to
function as a Line Lock Control. This allows the
Line Locks to be used for a burnout and at the
starting line.
4) S.F.O Mode 4 – Sets the S.F.O. output terminal to
function as a spare Transbrake output. This can
be used if the main Transbrake output was
damaged by a short.
5) S.F.O Mode 5 – Turns the S.F.O. output terminal off.
Note: If the S.F.O. terminal is not going to be used, set the
S.F.O. mode to 5.
The Line Lock Control is only set in Bracket Mode
but works the same in both Bracket Mode and Pro Mode.
When Line Lock Control is enabled, the Line Locks are
activated by themselves for a burn-out using the Line Lock
push-button. The Line Locks are activated again with the
Transbrake solenoid when the vehicle is staged.
