LEDs

LED

Color

Meaning

RUN

green

This LED indicates the terminal's operating state:

off

State of the EtherCAT State Machine: INIT = initialization of the terminal or BOOTSTRAP = function for terminal firmware updates

flashing

State of the EtherCAT State Machine: PREOP = function for mailbox communication and different default settings set

Single flash

State of the EtherCAT State Machine: SAFEOP = verification of the Sync Manager channels and the distributed clocks.
Outputs remain in safe state

on

State of the EtherCAT State Machine: OP = normal operating state; mailbox and process data communication is possible

ERROR1 - 4

red

Short circuit or wire break. The resistance value is in the invalid range of the characteristic curve.
