In operation send interval 1…*300…65535
Telegram value is sent cyclically according to time interval.
Transmission delay [2…255s] after bus
voltage return *2…255
The parameter defines the behaviour of the actuator at a bus power
return. The transmission delay time determines the period between
bus voltage recovery and the point after which telegrams can be sent.
Telegram limit active no
*yes
Telegrams which are sent by the gateway can be limited with this
parameter. If “yes”is selected, following parameters come up.
Telegram limit period 50ms…*10s…1dk
The limit period can be selected via telegram limit period parameter.
Max. number of transmitted telegram 1…*20…255

If an alarm is triggered, the drives move into a safe position and stay in
safe position until the event is over. You can select the priority of the
weather alarm. This parameter is applied for all blind/shutter channels
which are enabled for weather protection function. If more than
one weather alarms occur simultaneously, then only the alarm with
highest priority will be activated. The other lower priority alarms are
carried out after highest priority alarm is completed.
Wind alarm *disable

This parameter activates the wind alarm. If the parameter selected
“enable”,“Monitoring period for wind alarm in s [0…1000]”parameter
will be visible.
Monitoring period for wind alarm in s
[0…1000] *0…1000
The telegram of the active weather station is monitored cyclically. The
actuator waits for a telegram from the weather station within the cycle
time. If the telegram is not received within this monitoring period
time, actuator assumes that the weather station is broken or bus line is
damaged and the blind moves into the parameterized position.

7.4 List of scene
The scene function of the switch actuator has an 8 bit scene object. You
can define for each 64 scene with parameter window. 8 independent
values can be stored for each relay or each blind. The scene can be
specified that the relay OFF (open contact), or ON (close contact) its
state for switch function. If you use the blind, you can configure the
blind height and slat position. You can save height position for blind
also slat-opening angle as scene values.
When the actuator receives a telegram that retrieves a scene address:
• The output group is configured as a blind, the drive is moved into the
saved position and slats are turned.
• The output group is configured as a switch, the actuator evaluate the
transmitted scene address and switches the output to the stored scene
value.
A scene is activated when it receives its scene number at the scene
object. The storing of the current channel values is carried out using the
scene object.

7.5 "Enable Input a…s" parameter (continued)
7.5.1 "a - Switch Sensor" parameter
This function is used, for binary inputs to which a switch or a push
button is attached, to send a switching telegram (ON, OFF or TOGGLE)
as a reaction to a rising and / or falling signal edge at this input. It has
only 1 bit communication objects.
Debounce: Bouncing is the tendency of any two metal contacts in an
electronic device to generate multiple signals as the contacts close
or open; debouncing is any kind of hardware device or software that
ensures that only a single signal will be acted upon for a single opening
or closing of a contact.
A similar effect takes place when a switch made using a metal contact
is opened. The usual solution is a debouncing device or software that
ensures that only one digital signal can be registered within the space
of a given time (usually milliseconds).
Short/Long Press: Distinguishing short from long presses is about
measuring the pulse length. The event is no longer emitted upon
pressing the button, but upon releasing it. This can affect the feeling of
responsiveness.
The picture of this step shows a long press and short press timing, with
a long press threshold of Tl periods. The button press longer than Td
period but shorter than Tl period this mean is short pressed occurs.

7.8 "Blind" parameter (continued)
7.8.2 "A/B – Drive Blind" parameter
The blind actuator calculates the current position of a blind from the
running time. This calculation has to be performed because the drive
cannot provide any feedback on its position.
Detect travel times (Up/Down) via detection of end position
*set travel times
This parameter defines the travelling time of the blind. The time
needed for a complete travel from the upper into the lower end
position.
• Set the parameter to“via detection of end position”:
The duration of the current flow that the drive uses for the
movement from lower to the upper position. The device is measured
the travel time with current detection. Than up down movements are
stored.
• Set the parameter to“set travel times”:
This option is an alternative to automatic travel detection. In this way,
travel times for the lower to the upper end position are measured
with a stop watch then entered into the ETS parameters. The travel
times should be measured as precisely as possible because this times
is determined during ongoing operation.
Travel time UP in s[0…6000]
Travel time DOWN in s[0…6000]
If the “Detect travel times (Up/Down)”is selected “set travel times”,
this parameters are visible. The measured travel time values are
measured via stopwatch then enter this parameter.
Disconnect output from power after
*end position, no overflow
end position + %2 overflow
end position + %5 overflow
end position + %10 overflow
end position + %20 overflow
total travel time + %10 overflow
When the blind has been reached the end position (this means top or
bottom position), the blind is switched off its relay. An overflow time
can be set to ensure the output safely reaches the end position. The
voltage is supplied as an extra time after the blind has been switched
off.
Enable communication object
"Trigger reference movement” 1 bit
enable
*disable
If the parameter is selected “enable”, “ Trigger reference movement”
communication object is visible. The reference movement is triggered
via this communication object. In long time, slight inaccuracies can
occur so the upper and lower end positions are used for unique
determination of current position. A position calibration is possible by
executing the reference movement. A reference travel movement is
not re-triggerable.

If the "Limit travelling range" parameter is selected "via object
"Blind/shutter up down limited"", this parameter is visible. This
parameter set the blind upper/lower limit position in percent.
Pause on change in direction
(1-255 factor * 100ms) 1…*5…255
When the blind actuator of a drive that is currently moving, receives a
command to move opposite direction. The blind firstly stops than its
waits for the pause on change in direction than the blind is moved its
new direction.
Delay times for drive *standard
user defined
If the parameter is selected “user defined”, these parameters are
visible. You can show this below.
Different between coasting delay
and start-up delay in ms[-128…127] -128…*0…127
If the blind is closed lower end position, the used blind experiences
dead time between the times when the blind is started the
movement. You can compensate this time with this parameter.
