14. ERROR HANDLING
The control board can store up to 10 diff erent errors, with no. of occurrences limited to 10, for each event.
In case of blocking (severe) error, it is possible to restart the board by pressing both keys “+” and “-“ for 5 seconds or by switching off
and on the power supply. When restarting by means of keys, a memory check is performed and automatic recovery of out-of-range
parameters is done. The parameters are set to default factory values, so a new setup should be done, if necessary.
In level 4 menu, parameter “
H55
”, shows the list of events and error stored in memory. The display shows alternatively the error code
(
xx and the number of occurrences. Use “+” e “-“ for scroll the whole list.
At the end of the list, an exit code is presented: quitting (by pressing “F”) with
the error list is preserved, quitting with
the
error history is cleared to zero.
Events/warning not severe are stored in memory, without blocking the normal behaviour of the control board.
List of errors and events with the indication of blocking/not blocking:
