Output 1 switched off
Output 1 switched on
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.).
Switch-off process not yet completed,
wiring error: voltage detected at switched-off output ( with Ready LED green)
Output 1 switched on + prewarning threshold reached
Output 1 disabled (nominal current value is set to "OFF")
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.)
Output 1 triggered
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.)
State of the EtherCAT State Machine [} 94]: INIT = initialization of the terminal
State of the EtherCAT State Machine: PREOP = function for mailbox communication and dif-
ferent default settings set
State of the EtherCAT State Machine: SAFEOP = verification of the Sync Manager [} 96]
channels and the distributed clocks.
The outputs remain in safe state.
State of the EtherCAT State Machine: OP = normal operating state; mailbox and process
data communication is possible
State of the EtherCAT State Machine: BOOTSTRAP = function for terminal firmware updates
[} 154]
24 V DC supply voltage present and initialization completed, overcurrent protection active,
operation mode active
Programming mode / query mode active
Missing 24 V DC supply voltage or initialization error
Loading the factory settings
Wiring error or cable break (e.g. wrong ground reference)
Output 2 switched off
Output 2 switched on
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.).
Switch-off process not yet completed,
wiring error: voltage detected at switched-off output ( with Ready LED green)
Output 2 switched on + prewarning threshold reached
Output 2 disabled (nominal current value is set to "OFF")
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 2 can be read with flashing code (1x flashing = 1 A; 2x flashing = 2 A;
etc.).
Output 2 triggered
Output 2 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 2 can
be read with flashing code (1x flashing = 1 A; 2x flashing = 2 A, etc.)
