8.6.3 Relay Function Static / Flashing
Relay 3:
The pa
rameter setting “No”
(cannot be changed).
The function "Flashing" offers a connection option for warning devices to improve visibility. The frequency is
about 1 second with an impulse / pause rate of 1:1.
If “Flashing” is set,
the output circuit
mustn’t
be used as a safe output any more.
The combination of relay mode energized with flashing operation makes no sense and is therefore suppressed.

8.6.5 Horn Function
Relay 3:
The parameter setting cannot be changed.
The horn function of the alarm relay is activated if at least one of the two parameters (time or assignment to
digital input) is set. The horn function retains its functionality even for alarms in latching mode.
This feature is not allowed for safety-related alarm messages because the output is resettable.

The following possibilities to acknowledge are available for the alarm relay as horn relay:
•
By pressing the left button (ESC). Only available in starting menu.
•
Automatic reset at the end of the preset time (active, if value > 0).
•
By an external pushbutton (assignment of the appropriate digital input DI 1-n).
Due to fixed polling cycles, external buttons must be pressed for a few seconds before the reaction occurs.
