relates to auxiliary contact 1 and the reference on the right to auxiliary contact 2 ({reference of the
auxiliary contact 1} {reference of the auxiliary contact2}).

programming
Manual OFF: In this mode, the contact is permanently released whatever the external conditions or
programming
Automatic: In this mode, the auxiliary contact is activated according to the conditions and
restrictions of its programming.

Combination of events mode {1497} {1498}

This configuration defines how the various events intended to activate the auxiliary contact are
combined.
Either a single event suffices to activate the contact (OR function) or it must have all the active
events in order for the contact to be activated (AND function).
