F&F STR-421 User manual

PURPOSE
FUNCTIONING
The roller blind controllers STR-421 are designed for controlling
roller blinds (up and down movement) or other devices (for
example, gates) that are driven by a single-phase AC electric
motor and operated by means of momentary switches (for
example, bell-pushes). The controller can operate as an
independent unit (designated for opening/closing one roller blind)
as well as the controllers can be combined into groups that
enable the central controlling of many roller blinds

ROLLER BLIND CONTROLLER
double-button type
Supplied the relay is to sigal by shine of green LED U. The roller
blind motor is activated by the momentary switching of a current
pulse (L or N) to one of the control inputs. The motor is activated
at a time programmed previously by the user. The activation of
motor is to signal by shine of red LED “ or ”t.. Also, there is a
possibility of stopping the rolled blind activated at a level selected
by the user (non-complete opening or closing of the roller blind).
Control inputs of relay:
Local control - a group of push-buttons connected to joints 7
and 9 that controls one roller blind.
-upwards (opening); - downwards (closing).
Pressing the local control push-button activates the movement of
the roller blind in a selected direction. If the roller blind is already
moving, pressing the local control push-button will stop the roller
blind.
Central control - a common group of push-buttons for many
controllers (minimum two controllers) that controls all roller blinds
included in the central control system and connected to joints 4
and 6.
 - all upwards;  - all downwards.
Pressing the central control push-button activates the movement
of the roller blinds in a selected direction. If one of the roller blinds
is already moving in the same direction, its movement will be
continued. If one of the roller blinds is moving in the opposite
direction, this roller blind will be first stopped and then its
movement will be activated in the direction in accordance with the
command sent to the central input.
ATTENTION! The central control enables only activating the
movement of the roller blinds in a selected direction. The roller
blind will be stopped after the programmed movement time or
when any of the local control push-buttons is pressed.

Programming time of enclose
1. Press and hold a button PROG for time when green LED U start to
pulsate.
2. When we again press a button PROG (START). Controller start count
a time which is to signal by pulsate of green LED.
3. Press again a button PROG (STOP). Controller remember a counted
time. Programmin mode is automaticly closed ( green LED U shine
continually).
* If at time 30 sec from activate programming mode a
count of time doesn’t to start, then controller will out from
programming mode.
* Max time for programming 10min. Test by long time than
10 min to cause controller automaticly out from
programming mode.
* Input to programming mode posible is only when motor
of roller is OFF.
* In programming mode a controller doesn’t to react for
outward control signal .
Do not install to device which is broken or incomplete.
During assembly of controller should be take special care
Wrong connection could cause to give a shock and/or
break controller or connected device.
5. Controlled roller motor connect properly to joints 10 and 12 and to N.
To joint 11 connect to supply (L) of motor.
6. Take ON the power.
7. Programm time of upwards/downwards of roller. Prescribed is that
programmed time should be longer than 10 sec from real time of
upwards/downwards.
4. Choose control option (control impulse +/~ lor -/~)). Switch of local
control and central control connect with marks with function to joint to
choosen cable (for supply from DC to cable +, for supply from AC to
one common cable ~ ).
3. Connect power cable to joint 1-3 with marks.
Group of controllers which working with common central
control should be supplied from the same phase e.g only
L1.
All control inputs of controllers which works separately or
in group should have to common control impulse option -
all are controlling from the same device (e.g.
transormer).
Connection different device of supply to inputs of control
inputs of controller can cause to wrong work of system
and break controllers.
Choosing control option from DC to control inputs
should be put impulse + from the same device ( e.g.
tranformer)
