Performing a reset
Possible reset settings
When you confirm a fault, you confirm that you have taken account of the fault message. You
acknowledge fault messages with the Reset function.
You determine the reset method with the slide switch for AUTO/MAN RESET. You can choose
between manual and automatic reset. The position of the slide switch for AUTO/MAN RESET is
continuously read in by the controller during operation.
• Automatic reset: Automatic reset only functions with thermistor tripping and overload
tripping (thermal motor model overload). In the case of automatic reset, the fault
acknowledges itself automatically as soon as the cause of the fault (e.g. overheating of the
motor) is no longer active.
• Manual reset: With manual reset, you as the user must actively acknowledge the fault
message via the TRIP/RESET button on the device, the SF/RESET button on the operator panel,
a remote reset, or the IO-Link. All fault messages can be acknowledged manually.
"Non-acknowledgeable faults" are the exception. "Non-acknowledgeable faults" can only be
reset by removing the control supply voltage for at least 3 seconds. You can diagnose "non-
acknowledgeable faults" direct on the device by means of a flashing code sequence of the
three red LEDs. You can find the fault codes for "non-acknowledgeable faults" in Chapter
"Fault codes (only in the case of non-acknowledgeable faults) (Page 104)".
Note
Resetting switching states
When you acknowledge a fault, you confirm that you have taken account of a fault message. The
acknowledgment deletes the fault bits in the device but the switching states are not restored.
The switching states only become active again when the cause of the fault has been removed
and the switching relays are activated again.
You can find information on how to remove the causes of faults in Chapter " IO-Link diagnostics
(Page 106)".
The table below provides an overview of the possible reset methods depending on the pending
fault message:
Error message
Thermistor tripping
Overload tripping
Ground fault tripping
Switching element defective (current flowing de‐
spite disconnection)
Residual current tripping (switching relay switch‐
ed on but no current flow can be measured)
Current flow in operating mode "Cold start"
Connection abort in manual mode of the operator
panel
SIRIUS 3RB24 electronic overload relay for IO-Link
