3.5.2 Status LEDs
The status of an EtherCAT P port is signaled by two LEDs:
(1) (2)
Fig. 13: 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 EtherCAT ports. See chapter Status LEDs
[
}
22] of 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 U
S
and U
P
are switched off.
Green illuminated At least one of the output voltages (U
S
, U
P
) is switched on.
The output currents are within the nominal operating range. (I < I
n
)
Flashing green
Warning message [ } 29] .
Overcurrent on at least one of the output voltages.
Flashes red
Error message [
}
29] .
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.
Red illuminated
Error message [ } 29] .
At least one of the output voltages has been switched off due to a
protective function.
Red running light
(all four Status LEDs)
Error message [
}
29] .
Undervoltage or overtemperature.
