Pro Cube

INITIAL SETUP

Single vs Dual Trigger Interface Mode:
The PRO-CUBE Ò allows you to "hit" the tree twice and launch your vehicle on the quicker of two
reactions. If you want to take advantage of this double-hit capability, you have the option of using two
separate trigger (transbrake) switches or a single switch. If you choose not to use the double-hit capability,
you only need one transbrake trigger switch connected to the TRIGGER 1 terminal.
Select either Single or Dual trigger interface mode using any right-side ADJ switch.
The amount of cross-over time you have between the first and second hit will determine
whether it's best to use one switch or two. Using Single Trigger mode to hit both top bulbs is
generally not recommended unless you're at least 1.5 seconds faster than your opponent.
Hitting both top bulbs with two separate switches in Dual Trigger mode doesn't require as
much cross-over time. In Dual Trigger mode, TRIGGER 1 is always used for the first hit, and TRIGGER 2
for the second hit. In Single Trigger mode, TRIGGER 2 is ignored.
Another important difference between these two modes involves the Flinch Protection Ò feature.
Simply stated, flinch protection can prevent you from red-lighting when you accidentally release the trigger
switch before the tree starts. If this occurs using Dual Trigger mode, just press the same trigger switch again
and the delay that was started unintentionally will be reset. The delay will be restarted when the trigger
switch is released. In Single Trigger mode, however, the delay is not reset by pressing the switch again. In
this mode a known red-light situation can only be prevented by pressing and holding the TRIGGER 1 switch
until the bottom of your tree. Your vehicle will launch instantly when the trigger switch is released.
Timer Output Configuration:
Except for the 3 timer version, Timer 1 is a 4-stage output that can be cycled on and off twice. If you
want to cycle this timer on and off just once, use either pair of settings and set the other pair to 0. In the 3
timer version all three timers have 2-stage outputs that can be cycled on and off once each.
For compatibility with all types of equipment, Timers 1 and 2 can be configured for either
"normally off" or "normally on" mode. Timer 3, however, is fixed in "normally off" mode for
most common equipment and cannot be changed. Configure the timers as required for your
equipment using the front panel switches.
Note that the first on/off cycle of Timer 1 is adjustable in 0.001 (one thousandth) second increments
for very precise control. Timers 2 and 3 and the second on/off cycle of Timer 1 are adjustable in 0.01 (one
hundredth) second increments for extended down-track range (up to 39.99 seconds). Note the decimal point
location while setting timer values.
The diagram below illustrates a 4-stage pneumatic throttle stop application using Timer 1 in the
default "normally off" mode and factory settings for each stage. Note that the setting for each stage
represents time into the run, measured from launch.
