Description of the LED states of a CU310-2

There are four LEDs on the front panel of the CU310-2 DP housing.

MOD
The various LEDs are switched either on or off as the Control Unit powers up (depending on
the phase that the system is currently in). When switched on, the color of the LEDs shows
the status of the corresponding power-up phase.
In the event of a fault, power up will be ended in the corresponding phase. The LEDs that
are switched on retain their colors so that the fault can be determined on the basis of the
combination of the color LEDs that are lit and unlit.
All the LEDs go out briefly if the CU310-2 DP has powered up without fault. The system is
ready for operation when the LED "RDY" is permanently green.
All the LEDs are controlled by the loaded software during operation.
