EL9576 - LEDs and pin assignment 2:

Correct supply voltage is necessary for operation!

In addition to the supply voltage via the contacts on the front panel, the voltage from the E-bus must also be present in order for the terminal to work properly, since the integrated logic of the Bus Terminal is supplied with this voltage. The Bus Terminal does not work if the supply is incorrect.

Note

Match the resistor power to the expected power!

When selecting the external resistor, make sure that the rated power of the resistor is matched to the expected power, since otherwise the resistor and adjacent components can be damaged. In addition, the temperature model is to be adapted to this resistor.

EL9576 - 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

flashing

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

single flash

State of the EtherCAT State Machine: SAFEOP = verification of the Sync Manager channels and the distributed clocks.
The 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

Out voltage OK

green

ON

Supply voltages are OK, there are no errors

OFF

  • Supply voltage is incorrect, i.e. too high or too low
  • Overtemperature in the temperature simulation
  • Temperature at the terminal too high

Over voltage

yellow

ON

The supply voltage has exceeded the threshold value for overvoltage.

Temp warning

yellow

ON

Temperature threshold value for the temperature on the PCB has been exceeded.

Under voltage

yellow

ON

The supply voltage is too low, or has fallen below the corresponding threshold value in the CoE data.

Temp R warning

yellow

ON

The “I2T warning level” threshold value has been exceeded.

Chopper On

yellow

ON

The external resistor is switched on.

Error

red

ON + “Undervoltage” LED

The supply voltage is not connected or is so low that the “supply voltage” and “ResistorCurrent” values cannot be read.

ON + “Temp R Warning” LED + “Overvoltage” LED

There is an overtemperature in the internal temperature simulation for the external resistor.
