Safety Function Blind

The global safety function is activated on the Extended settings tab with the parameter Device safety and the global settings are parameterized there.

The effect of the safety function can be parameterized here for each channel. You can enable the safety function individually for each drive.

Ext. 1/2 Output 1+2 / 3+4 / 5+6 / 7+8 -Blind/roller shutter	Safety function
-Safety and alarm settings	Safety function	Disabled Enabled
	Behavior at start of safety	No reaction Stop Up Down Move to position
	Height position at start of safety in %	0 (0-100)
	Slat position at start of safety in %	0 (0-100)
	Behavior at end of safety	No reaction Up Down Move to position prior safety Accept current automatic position
	Behavior at exceeding cycle time	No reaction Stop Up Down Move to position
	Height position on exceeding cycle time in %	0 (0-100)
	Slat position on exceeding cycle time in %	0 (0-100)

The safety function is activated if the safety object receives a telegram with the object value that you defined with the parameter Device safety (). You can define the reaction using the parameter Behavior at start of safety.

No reaction: Finish actual task.
Stop: The drive remains in its current position.
Up: The drive moves to the upper end position.
Down: The drive moves to the lower end position.
Move to position: The drive moves to the defined position for height and slat (for blind only).

If the safety object receives a telegram with the object value opposite of that for activation, the safety function is canceled and the output relay adopts the state that you defined in the parameter Behavior at end of safety.

No reaction: The drive remains in its current position.
Up: The drive moves to the upper end position.
Down: The drive moves to the lower end position.
Move to position prior safety: The drive returns to the position it had before the safety telegram.
Accept current automatic position: This setting is only useful if the automatic function is active. The drive moves to the last automatic position requested.

The device then waits for a telegram from an external sender within the globally set cycle time. If such a telegram is not received within the monitoring time, the parameter Behavior at exceeding cycle time is used to determine what is to happen.

No reaction: The drive remains in its current position. Block for new commands, but finish actual task.
Stop: Block for new commands, and the drive remains in its current position.
Up: The drive moves to the upper end position. Block for new commands.
Down: The drive moves to the lower end position. Block for new commands.
Move to position: The drive moves to the defined position for height and slat (for blind only). Block for new commands.
