Status LEDs

The status of an EtherCAT P port is signaled by two LEDs:

Status LEDs 1:
LEDs of EtherCAT P ports (example: X54)

(1) EtherCAT Link/Activity (L/A)

The L/A LEDs of EtherCAT P ports behave like the L/A LEDs of the EtherCAT ports. See chapter Status LEDs of the EtherCAT ports.

(2) Output voltage status

Each EtherCAT P port is assigned an LED that signals the states of the output voltages of this port.

LED signal

Meaning

Off

The output voltages US and UP are switched off.

Lights up green

At least one of the output voltages (US, UP) is switched on.

The output currents are within the nominal operating range. (I < In)

Flashing green

Warning message.

Overcurrent on at least one of the output voltages.

Flashes red

Error message.

This signal is output in two cases:

  • At least one of the output voltages has been switched off within the last 20 seconds due to a protective function.
  • The box has been switched on within the last 20 seconds. Prior to switching on there was an error message that had not yet been reset.

Lights up red

Error message.

At least one of the output voltages has been switched off due to a protective function.

Chaser light red
(all four status LEDs)

Error message.

Undervoltage or overtemperature.
