INDICATIONS
LED indications can be very useful in case of problems with the instrument.
The green LED is normally used for instrument status indication, like normal operation or special function mode. For
DeviceNet it is also possible to show that the instrument is in abort state and idle state. The red LED is normally used
to for error/warning indication (how longer the flash, how greater the trouble).
