ABB i-bus® KNX FUNCTION
Switch-off takes place when the value 0 is received:
• on the group object Switch
• on the central group object Switch
• on the group object Scene 1...64
• on the central group object Scene 1 ... 64
• as the result of the → Function Logic, Page 84
• as the result of the → Function Threshold, Page 85
If, when a Scene number is retrieved, a Delay is used, the Delay for switching ON and OFF is not taken
into account.
If switch-on is repeated during the Delay for switching ON, the Delay for switching ON is restarted.
If switch-off is repeated during the Delay for switching OFF, the Delay for switching OFF is restarted.
If a switch-off occurs during the Delay for switching ON T
If a switch-on occurs during the Delay for switching OFF T
4.1.13.2.1 Disable delay for switching ON and OFF
The function Delay for switching ON and OFF can be disabled via the group object Disable delay for
switching ON and OFF . If the function Delay for switching ON and OFF is disabled, the switch-on com-
mand is forwarded without time function in the function chain (→ Function diagram of Switch Actuator,
Page 77) and the output reacts according to its parameterization.
4.1.13.3 Function Flashing
If the function Flashing is used, the relay is alternately opened and closed after receipt of a switch-on
command. The switch-on command is issued via the group object Flashing .
The parameter Flashing if group object Flashing equals can be used to define the value with which a
flashing cycle can be stared and prematurely ended.
The number and duration of switching operations can be defined in the following parameters:
• Time for ON
• Time for OFF
• Number of flashing cycles
Each flashing cycle begins with the On state. Whether the relay is opened or closed depends on whether
the output is defined as an NC contact or NO contact in the parameter Reaction of output.
Each flashing cycle begins with the Off state. The relay contact position after the flashing cycle is ended
can be defined in the parameter Contact position after flashing.
The flashing cycle restarts when a switch-on command is received on the group object Flashing .
If the output is flashing, it will not react to:
• Group object Switch
• central group object Switch
• Group object Scene 1...64
• central group object Scene 1 ... 64
• Result of the → Function Logic, Page 84
• Result of the → Function Threshold, Page 85
