EMO Switch
The EMO switch,
Emergency Off Switch
, is the illuminated red switch on the front of
the instrument. If it is blinking slowly the instrument is in the middle of an ignition
cycle.It blinks rapidly after the Emergency Off Switch is depressed. This is an
indication that the switch has been depressed and to remind you to push the switch
again to release it. This switch shuts off the plasma in an emergency by
disconnecting the main voltage circuitry in the RF generator. To restart, you must
release the switch by pressing the switch again. Reset the RF generator using the
software Reset button. (The spectrometer stays on.)
