Risk of damage of the blind drive
CAUTION
This version of Set 9 (different than sets 9, 10 and 11 based on LOGO! 7) is
based on LOGO! 8 and requires the use of modern blind drives with integrated
end position switch.
If this requirement is not observed, the blind drives can be damaged.
In case you want to use blind drives without integrated end position switches,
you must modify the LOGO! program.
Risk of property damage or personal injury.
In "maintenance mode", the blinds move up automatically.
In "automatic mode", the blinds move up and down automatically.
WARNING
When operating the blinds, make sure there are no body parts or other objects in
the way.
Note The preset maximal blind runtime of 40 seconds until the end stop (in LOGO!
program) is only an example and can possibly be greater than the real runtime of
the blinds.
Check the exact runtime until end stop of the blinds you use. If necessary, adapt
the wiping relay pulse width in the LOGO! program (see Chapter 3.7).
For each blind, a 0.5 seconds pause for the direction change was programmed for
protecting the motor against direct rerouting.
Independent of the operating mode, the blinds have been programmed to open or
close completely. A change of direction during travel is possible by activating the
other direction.
The LOGO! TDE or the LOGO! display can be used to predefine manual or
automatic control of the blinds.
In manual mode, the blinds can be controlled with buttons or with the cursor keys
over the LOGO! controller and the LOGO! TDE. In addition, the blinds can be
controlled with a tablet, smartphone or PC with the F-keys over the integrated
webserver of LOGO! 8.
With LOGO! function block "Astronomical clock" the blinds are, in automatic mode,
moved up at sunrise and moved down at sunset during the week. On the weekend,
the blinds are moved up at 08:00 a.m. and down at 08:00 p.m. A random generator
can delay the time of automatic opening and closing up to 30 minutes. Even
though the house is empty, this makes it seem that somebody is in the house.
Manual operation of the blinds is still possible in automatic mode.
In maintenance mode, all blinds move up. Closing the blinds is only possible after
the maintenance mode has been deactivated. Maintenance mode can just be
activated in manual mode. The upward movement of the blinds can be stopped
anytime by pressing the button for the opposite direction.
The function blocks for the automatic control of the blinds can be called up in
parameter assignment mode
or LOGO! TDE. This enables modification of individual parameters like days of the
week and times to open/close the blinds.
