Note
For every appliance fault, output X2.10 issues a 230V
signal.
In the case of temporary faults, the output switches the
signal through for a specific time.
In the case of faults that result in a permanent appliance
shutdown, the output switches through permanently.
 You can define the characteristics of the output via
parameter "COMMISSIONING/ I/O CONFIGURATION/
OUTPUT X 2.10".
