4.3.4 Slat adjustment time
only at blinds
The slat adjustment time specifies the time period during which the slats are adjusted from 0% to
100% or vice versa. The shutter actuator thus controls the slat adjustment for the duration of the set
value.
Tip for the measurement of very small slat movement times:
Move the slats in a final position (either 100% closed or 100% opened)
Now send step commands until the other final position is achieved
Multiply the number of steps with the adjusted time for the step time of slats
E ter the result to the slat adjust e t ti e
For a large slat adjustment time the procedure is recommended as described in 4.3.1.
4.3.5 Pause on reverse
The pause on reverse is used to protect the shutter motor, if the shutter actuator simultaneously
receives commands for the up and down movement. A direct changeover from one direction to the
other can significantly reduce the life time of the motor and lead to complete destruction in some
cases.
If a shutter actuator receives a movement command to the other direction during an active
movement command, the actuator first switches off both commands. The shutter actuator then
waits for the reversed pause before setting the relay for the next direction
The reverse pause is valid for the reversion of the direction at the up/down movement as well as for
the slat adjustment.
Too short selected reverse pauses can damage the motor!
Urgently observe the manufacturer specifications in the data sheet of the drive.
4.3.6 Switch-on/Switch-off delay motor
Some motors do not deliver full power immediately, but only after a few milliseconds. This time,
which the motor needs until it reaches the full power, can be compensated with the setting of the
"switch-on delay motor".
On the other hand there are motors, which run after a few milliseconds after switching off. This
behavior can be compensated by setting the "Motor off-delay" setting.
4.3.7 Position of slats at end of driving
only at blinds
Via the setting "position of the slats after end of ", it is possible to set the position in which the slats
are to be driven after a descent movement, which is controlled via the object 13 "roller shutter up /
down". This position is automatically activated by the blind actuator after a shutter travel. The slat
position after the end of travel can be set as a percentage of 0-100% in 1% steps, 0% being fully open
and 100% fully closed.
When a stop command is sent during the movement this position is not approached, since the
sequence is stopped or interrupted.
