4.9 Power failure

The following conditions may occur in the event of a power failure:
- The power failure occurs during the standby phase, during a parameter reset phase, during the statistics
analysis phase. In all these cases, the module returns to stand by and displays the clock with the
battery on icon, meaning a power failure. If the power failure occurs during a parameter reset, the reset
is closed without saving any changes made and at the end of the power failure it will be necessary to
go to parameter reset again and make the changes.
- The power failure occurs during a phase transition or a microswitch search. In this case, the module
still displays the current phase, the battery icon is turned on to indicate the blackout, the turning bar
is blocked to indicate that the motor has stopped. At the end of the power failure, the motor restarts
to complete the movement.
- The power failure occurs during a phase of the regeneration cycle. In this case, the module still displays
the current phase, the battery icon is turned on to indicate the power failure, the time count down is
stopped. At the end of the power failure, the stoppage time count is restarted and the process goes to
the next step.
- The power failure occurs during an alarm. In this case, the module still displays the alarm and the
battery icon is turned on to indicate the power failure. At the end of the power failure, the module
remains in alarm status.
