Description of the LED states of a CU 310-2

There are four LEDs on the front panel of the CU310-2 DP's housing (see section:
"Overview", illustration: "CU310-2 DP Interface overview").

The various LEDs are switched on and off as the control unit is powered up (depending on
the phase the system is currently running through). When switched on, the color of the LEDs
shows the status of the corresponding power-up phase (see section: "LED display during
power up").
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 error. The system is
ready for operation when the LED "RDY" is permanently green.
All the LEDs are controlled by the software loaded during operation (see section: "LED
display during operation").
