EL3042 - Connection, display and diagnostics 2:

Overcurrent protection of the 20 mA inputs

The current inputs are protected against damage by overcurrent by an internal current limitation, currents > 30 mA may occur.

  • In the event of a fault, the current limiter must not be overloaded by a voltage > 30 V from the source device.
  • Overcurrent is displayed in the process image as "Overrange".
  • After occurrence, the error condition must be stopped immediately, the source device switched off or disconnected from the input terminal.
  • If the error condition persists for a longer period of time, the internal terminal current limitation reduces the absorbed signal current for thermal reasons, depending on the ambient conditions also below 20 mA.

EL3042 - LEDs

EL3042 - Connection, display and diagnostics 3:Fig.26: EL3042 - RUN and ERROR LED

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 or BOOTSTRAP = function for firmware updates 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.
Outputs remain in safe state

on

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

ERROR **)

red

Fault indication for broken wire and if the measuring range for the respective channel is exceeded (under- or overrun)

*) If several RUN LEDs are present, all of them have the same function.
**) The error display shows the signal processing state for each channel.
