LED will turn “off” after the initialization meaning that the laser is ready to fire.
However, if the LED stays on afterwards, that means the laser source is
malfunctioning.
When the last LED from the left turns “ON”, the incoming voltage to the laser
source is incorrect. Check that the output voltage to the laser source is correct.
Note: If the electrical circuit in the laser source has been damaged then the
signals shown may not reflect the exact problem.
Setting tickle pulse on Spirit machines equipped with Synrad laser sources.
By nature, Synrad laser sources require a tickle pulse to keep the laser ready
for firing. The tickle pulse signal required depends on the individual laser tube.
The usual setting is at 5k, however, it may be required to adjust the tickle pulse
rate. If the laser is too weak, we can set it to 7k and if the laser is bleeding, then
we can set it to 3k.
Hold the “down arrow key” when turning on the machine until “Laser Tube
