following table. In the case of more than one error, the error with
the highest priority will be displayed until it is resolved.
In the case of normal operation, the LED flashes at a frequency of ½
Hz. In the case of an error, the LED remains off for 4 seconds, then at
a frequency of 1Hz, it flashes a number of times equal to the error
code and than remains off again for 6 seconds. If the error code
has 2 digits, the flashing is interrupted for 2 seconds between the

Example: error 23: LED off for 4 seconds. 2 flashes at a frequency
of 1Hz. Off for 2 seconds. 3 flashes at a frequency of 1Hz. Off for
6 seconds. The cycle repeats until the LED turns off because the
problem is resolved or if an error with higher priority occurs.
