Acknowledgment of faults
Generally, the following applies to the acknowledgement of faults:
● Faults can only be acknowledged
– if the cause of the fault has been eliminated
– if there is no "ON" control command pending.
● A reset will not be possible if the cause of the fault has not been eliminated and / or if an
"ON" control command is pending. The reset will be saved depending on the type of fault.
Saving a reset is indicated by the "GEN. FAULT" LED on the basic unit and on the
operator panel. The LED changes from flashing to continuous signal.
Automatic acknowledgement of faults
Faults are automatically acknowledged in the following cases:
● A reset has been saved and the cause of the fault is no longer present (user has
previously acknowledged the fault)
● Auto reset of an overload trip or thermistor trip if motor protection reset = Auto (an
automatic acknowledgment is issued here after expiry of the cooling down period). The
motor cannot start immediately since reset cannot be performed when an ON command
is pending.
● If a configured module fails, all related faults will be acknowledged automatically.
However, a configuration fault will be generated (exception: operator panel, if
parameterized accordingly). This ensures that a module fault does not cause the general
fault to be acknowledged automatically.
● If a function or module is deactivated in the device configuration (via parameterization),
all related faults are acknowledged automatically. The motor cannot start immediately
since parameters cannot be entered if an ON command is pending.
● If a parameter of a function is changed from "Tripping" to "Warning", or to "Signaling" or
"Deactivated", all related faults will be acknowledged automatically.
● For an external fault: With its own parameter: "Auto-Reset."

Description
Activation of the "Reset" function block by any signal (any sockets, e.g. device
inputs, communication bus control bits, etc.).
The blue Test / Reset buttons on the basic unit and the operator panel are
usually intended for acknowledging faults and for performing a device test.
The buttons can be disabled with "TEST/RESET keys disabled". These can then
be used for other purposes. On the operator panel with display, the buttons are
disabled via a menu function (default: not disabled).
