7.13 External fault evaluation
7.13.1 External fault detection
Description
Use the internal digital signal DCTRL1−TRIP−SET to evaluate external disturbances and integrate
them into the monitoring of the system. If an external disturbance is recognised, the controller
indicates the fault EEr and sets controller inhibit.
)
Note!
The function is LOW active.
Activation
·
C0410/11 (DCTRL1−TRIP−SET) must be combined with digital signal source.
·
LOW level at the signal source for DCTRL1−TRIP−SET sets fault message EEr and activates
the controller inhibit.
)
Note!
Use C0007 to carry out a fixed configuration of DCTRL1−TRIP−SET with the digital
inputs X3/E1 ... X3/E4. C0410/11 will be automatically adapted.
7.13.2 Reset of external faults
Description
You can reset a fault message with the internal digital signal DCTRL1−TRIP−RESET, when the cause
of disturbance has been removed.
)
Note!
A LOW−HIGH signal resets the fault message.
Activation
