4. MPORTANT Switches MUST be set prior to turning power on to X FIST The microcontrollers ONLY read the switch settings on power up If changes need to be made turn unit OFF set switches and cycle power back ON The G SWITCH used by the X FiST closes at 2 1G 10 please keep this in mind for SLOW launches If your rocket will have less then 2 1G s 10 of acceleration please configure your system for PULL PIN operation Unit MUST be powered OFF when installing pyrotechnics to the X FiST ONLY turn power on AFTER the X FiST has been installed the rocket is setup on the launch pad and you are ready to launch the rocket NEVER transport your rocket with an X FiST that is installed and powered up Not following these precautions can cause damage and a potential injury safety is critical AIR START Configuration and Operation The AIR START stage begins countdown after the G SWITCH has closed Figure 2 shows the DIP switch and the associated values of each switch To activate a switch you move it to the upper position towards the ON silk screened on the DIP switch Figure 2 AIR START stage DIP Switch with all switches in the OFF position Switch Value Table 1 gives examples of a few of the DIP switch settings for the AIR START stage For example to get a delay of 3 0 seconds you would turn ON switch 2 and switch 3 1 second 2 seconds 3
