ABB FTIR Status LEDs
Power light should be on with the power supply is active.
Scan light should light up when the interferometer starts scanning.
ZPD light is to indicate that the interferometer is looking for the ZPD, it should light up for a few seconds during the start up sequence and then turn off.
Data indicates that the interferometer sends data. This is the normal state when the startup sequence is done, this light should remain blinking.
