Meaning of the EL9222-xxxx LEDs and button LEDs
LED
Color
Meaning
Button
LED 1
Button LED 1 indicates the status of output 1.
Green
off
Output 1 switched off
on
Output 1 switched on
flashing
Programming mode active:
Permissible nominal current value for output 1 can be read with flashing code (1x flashing =
1 A; 2x flashing = 2 A, etc.).
flickering
Switch-off process not yet completed,
wiring error: voltage detected at switched-off output ( with Ready LED green)
Orange
on
Output 1 switched on + prewarning threshold reached
Flash (after
pressing)
Output 1 disabled (nominal current value is set to "OFF")
flashing
Reverse current active
or
Query mode or programming mode active (additionally orange Ready LED is on):
Nominal current value cannot be changed because disabled or fixed variant; set nominal cur-
rent value for output 1 can be read with flashing code (1x flashing = 1 A; 2x flashing = 2 A;
etc.)
Red
on
Output 1 triggered
flashing
Output 1 triggered and cooling phase active
or
Programming mode active (additionally Ready LED orange on):
Sum current of both outputs exceeded, impermissible nominal current value for output 1 can
be read with flashing code (1x flashing = 1 A; 2x flashing = 2 A, etc.)
Run LED
Run LED indicates the EtherCAT operating state of the terminal
Green
off
State of the
INIT
= initialization of the terminal
flashing
State of the EtherCAT State Machine:
PREOP
= function for mailbox communication and dif-
ferent default settings set
Single flash
State of the EtherCAT State Machine:
SAFEOP
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
Ready
LED
Ready LED indicates the status for overcurrent protection / programming mode / query mode
Green
on
24 V DC supply voltage present and initialization completed, overcurrent protection active,
operation mode active
Orange
on
Programming mode / query mode active
Red
on
Missing 24 V DC supply voltage or initialization error
flashing
Loading the factory settings
flickering
Wiring error or cable break (e.g. wrong ground reference)
Button
LED 2
Button LED 2 indicates the status of output 2.
Green
off
Output 2 switched off
on
Output 2 switched on
flashing

Orange
on
Output 2 switched on + prewarning threshold reached
Flash (after
pressing)
Output 2 disabled (nominal current value is set to "OFF")
flashing
Reverse current active
or
Query mode or programming mode active (additionally orange Ready LED is on):
