Overview Block Roller shutter

Block function block for the control element Block Roller shutter safety; the control element must be connected with this function block. See Block Presence and Presence General.

This function block implements a safety function for blinds. If the wind speed rises above a preset value or rain is detected (provided the rain safety is activated), the blind is moved to the configured safety position (height and slat) and after a configurable time the actuator is locked.



Inputs
AK
 Active
 Active. When 1 is present at the input, monitoring is active, otherwise switched off.
WI
 Wind km/h
 Wind speed in km/h.
RE
 Rain
 Rain message. If 1 is present at the input, rain is detected. Only evaluated when the setting "Rain safety" in the control element is set to Active.

Outputs
AL
 Alarm
 If the wind speed exceeds the configured limit or, with rain safety activated, rain is detected, the alarm output is set.
AS
 Actuator lock
 If the alarm is triggered by wind or rain, first the configured safety position is sent to all height and slat outputs and after a delay time the actuator lock is activated.
H1
 Height percent Setpoint height and slat. If the alarm is active, the configured safety position for height and slat is output every 10 seconds.
L1
 Slat percent

Parameters

Number of outputs Number of outputs for height and slat.

Delay actuator lock If the alarm is triggered by wind or rain, first the configured safety position is sent to all height and slat outputs and after this time the actuator lock is activated. This time should therefore always be greater than the travel time height of the blind.
