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

fast flashing

State of the EtherCAT State Machine:
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

WARNING

Do not operate current transformers in no-load mode!

Please note that many manufacturers do not permit their current transformers to be operated in no-load mode! Connect the EL3413 to the secondary windings of the current transformers before using the current transformer!

Neutral conductor

WARNING

Earthing of the terminal point N when measuring current!

If you do not connect the terminal point N with the neutral conductor of your mains supply (e.g. if the terminal is used purely for current measurements) and use the IN current measurement channel, terminal point N should be earthed, in order to avoid dangerous overvoltages in the event of a current transformer fault.

Earthing of the N point is not absolutely necessary if only the galvanically isolated current channels are used.
