LED

Color

Meaning

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

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

flickering

State of the EtherCAT State Machine: BOOTSTRAP = function for Firmware updates of the terminal

ERROR
Ch1, 2

red

- Analog output overload: wire break at I output, short circuit at U output
- Setpoint exceeds Limiter: below low limit /above high limit
- Internal error DAC

Notice

Cable lengths > 30 m

For longer cable lengths > 30 m, suitable overvoltage protection must be provided (e.g. EL9540-0010) if corresponding interference could affect the signal cable.

*) Constant current; short-term higher currents are to be avoided and can cause thermal overload (damage)

**) The "GND" potential is internally coupled to the "0V" potential, but is subject to a reduced current carrying capacity

***) The connection point connects directly to the DIN rail contact.
Shield connections should generally be de-energized (DC)! See analog technical information in the Beckhoff analog manual.
If possible, an external shield connection, e.g. via Beckhoff ZB8511 or similar, is preferable.
