Meaning of the EL9227-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 ( with green Ready LED ),
wiring error: voltage detected at switched-off output ( with red Ready LED )
Orange on Output 1 switched on + prewarning threshold reached
Flash (after
pressing) Output 1 disabled (nominal current value is set to "OFF")
flashing 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 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 EtherCAT State Machine [
}
94] : 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 = verification of the Sync Manager [

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 = function for terminal firmware updates

Status
LED 1 Status LED 1 shows additional information for output 1
Orange on Output 1 has detected undervoltage or overvoltage
Red flashing Cooling phase output 1 active
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, op-
eration mode active
Orange on Programming mode / query mode active
Red on Missing 24 V DC supply voltage, initialization error or wiring error
(together with Button LED flickering green; e.g. supply at output)
flashing Loading the factory settings
flickering Wiring error or cable break (e.g. wrong ground reference)
Status
LED 2 Status LED 2 shows additional information for output 2
Orange on Output 2 has detected undervoltage or overvoltage
Red flashing Cooling phase output 2 active
Button
LED 2 Button LED 2 indicates the status of output 2.
Green off Output 2 switched off
on Output 2 switched on
flashing Programming mode active; permissible nominal current value for output 2 can be read with
flashing code (1x flashing = 1 A; 2x flashing = 2 A, etc.).

rent value for output 2 can be read with flashing code (1x flashing = 1 A; 2x flashing = 2 A;
