6.5 Meaning of LEDs
There are four LEDs on the front panel of the CU305 housing.
RDY Ready
COM Option Board
OUT>5V Encoder current supply > 5 V (TTL/HTL)
MOD Operating mode (reserved)
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
switched on retain their current colors so that the fault can be determined on the basis of the
combination of the colored lights that are lit and unlit.
Once the CU305 has booted correctly, all the LEDs are switched off briefly.
The system is ready to operate when the "RDY" LED lights up green permanently.
All the LEDs are controlled by the software loaded during operation (see section: "LED
display" during operation).
Note
Fault code with BOP inserted
If the fault code F01018 appears on the display when the BOP is inserted, this means that
power up of the CU305 has been aborted due to a software fault or incorrect
parameterization. The device is reset in this case and automatically restarted using the
factory settings.
