For faults with pop-up, the pop-up will be cleared when fault will be cleared or by pressing any button on the front face of the
controller. The total number of faults logged on the controller is dynamic, as the total number of “ alarms” is 100 (not
including the events, which are 300) and uses a FIFO ordering.
To clear Faults through the display, it is possible inside the LOG/FAULTS menu with the option “PRESS OK TO CLEAR
FAULTS”, using the configurator profile password (1000). There is also a shortcut by holding the
button for 1.5s and
validating on the pop-up that appears. If the fault is still active, it will be inside the log “in progress” but the fault LED and
output will be off. If the faults are not active any more, they will be logged in the “history” log. This way to clear the fault will
be automatically proposed by the controller through a pop-up:
