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
”
. 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 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) connected to joints 4 and 6
that controls all roller blinds included in the central control system.
- 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.
