Switching/Blind Actuator
39
Each blind/shutter channel can be configured and participated by “Response with safety” and
“Assignment to safety objects” parameters for safety functions. Response with safety parameter
specifies in which safety function the blind/shutter participated. The possible selections for safety start
/ safety end;
Safety ineffective
Upper end position/unchanged
Upper end position/current object value[%]
Upper end position/same as before safety
Lower end position/unchanged
Lower end position/current object value[%]
Lower end position/same as before safety
The possible selections for safety objects that will be used for safety start and safety en:
Safety1
Safety2
Safety3
Safety2
Safety3
Safety3
Safety3
For safety start there are two possible selections: Upper end position and Lower end position. If the
selected safety object (or objects) is set to “1” the blind travels for Upper end position or Lower end
position according to the selection.
For safety end there are three possible selections: Unchanged, Current object value and Same as before
safety. If unchanged is selected, the blind channel does not change its position. The current object
value [%] means that the blind travels to the level of the last %height object value.

Bus Failure Function
The behaviour of the blind/shutter channel can be specified when the bus voltage fails. There are three
possible selections for bus failure situation:
Unchanged: The blind/shutter channel does not respond the bus failure.
Upper Final Position: The blind/shutter travels to the upper end position.
Lower Final Position: The blind/shutter travels to the lower end position.
