Table 3.6: Switch positions of alarm contact
The alarm contact is activated by selected events according to their tolerances (see
section 6.3.3).
In addition to activating an external alarm when triggered by an error or warning
message from the Sunny Boy Control, the alarm contact can also be set to activate
the alarm when triggered by a power failure. This requires making contact 1-2 the
default switch position of the alarm contact. However, this will also trigger the alarm
during initialization of the Sunny Boy Control until it starts operating.
