EL9550-0010 - Connection, LEDs and process data
Fig.49: EL9550-0010LED | Color | Meaning | |
|---|---|---|---|
Power-LED field | green | off | 24 VDC - field supply not available |
on | 24 VDC - field supply available | ||
Power-LED system | green | off | 24 VDC - system supply not available |
on | 24 VDC - system supply available | ||
Us Low LED | red | off | no error |
on | Undervoltage, Us below 18 V | ||
Up Low LED | red | off | no error |
on | Undervoltage, Up below 18 V | ||
RUN | green | These LEDs indicate the terminal's operating state: | |
off | State of the EtherCAT State Machine: INIT = initialization of the terminal | ||
Flashing | State of the EtherCAT State Machine: PREOP = function for mailbox communication and different default settings set | ||
Flashing | State of the EtherCAT State Machine: SAFEOP = verification of the Sync Manager channels and the distributed clocks. | ||
on | State of the EtherCAT State Machine: OP = normal operating state; mailbox and process data communication is possible | ||
Flashing | State of the EtherCAT State Machine: BOOTSTRAP = function for Firmware updates of the terminal, for example | ||
