Controller for external roller shutters 12/24 STR-4P for the box F&F

Operation

The controller for external blinds and shut ters can work as a standalone device designed to cover or uncover one blind. It is possible to combine controllers into groups and control multiple blinds. Power supply of the controller is indicated by a green LED. The shutter motor is activated by momentarily applying N signal to one of the control inputs. The motor is switched on for the time programmed by the user, allowing the roller shutter to be fully raised or lowered. It is possible to stop the running roller shutter at the level selected by the user (incomplete covering or uncovering of the roller shutter).

Control

The inputs of the controller for external roller shutters are divided into two groups: local control and central control.

Local control
Depending on the connection method, the controller can operate in one or two local buttons mode.
TWO LOCAL BUTTONS
Each direction of movement has its own local button. When pressed briefly (<0.5 s), it activates the roller shutter to move in the preset direction for a programmed period of time. If the roller shutter is already in motion when the button is pressed, it will be stopped. If the button is pressed for a long time (>0.5 s), the roller shutter will be activated for movement in the preset direction for the whole period of time when the button is pressed (the function makes it possible, for example, to adjust the slope of the slats).
ONE LOCAL BUTTON
Local control input Bottom is permanently connected to line N. A button is connected to the Up local control input, which alternately turns the roller shutter on one way or the other. Briefly pressing the button (<0.5 s) turns on the roller shutter for the programmed time. If the roller shutter is already in motion when the button is pressed, it will be stopped. A long press of the button (>0.5 s) activates the roller shutter for the time the button is pressed.
Each subsequent press of the button will start the roller shutter in the opposite direction to the previous one.

Central control
The controller always cooperates with two central control inputs.
Central control allows you to switch on the roller shutters for movement only in the selected direction. The roller shutter will stop only after the programmed time has elapsed, or after pressing any local control button.
If a central command with the opposite direction is given during the execution of the central control command, the roller shutter will be stopped first and then, after a break of 1.5 s, the motor will be started to work in the opposite direction.
The time ofswitching on the roller shutter in the central control can be randomly delayed (by a maximum of 1 s) - this serves to minimize the current surge in the network in case of simultaneous activation of multiple controllers.

The Central-Down button has an additional function for closing and locking the roller shutter in the closed position. If the Central-Down button is pressed and left in the ON position, the controller will close the roller shutter and will not allow it to open until the Central-Down button is released (operation of the other inputs will then be blocked). This function makes it possible to lock the roller shutters in case of, for example: arming the alarm, detecting rainfall (after using additional rain sensor STR-R) or too strong wind (after using additional wind sensor STR-W).

Functions

- local and central control
-universal one- or two-button control
-support for 12/24V DC drives
-interlock function
permanent signal on Central Down input prevents control of all buttons until the signal is removed
-cooperation with external rain and wind sensors and alarm control panels
- direction memory
for local and central control. If the controller executes the Central-Up command, the next press of the local button will operate the roller shutter downwards
- asynchronous start
roller shutter activation time in the central control is randomly delayed (maximum 1s) to minimize the current surge in the network in case of simultaneous activation of multiple drives
- low standby power consumption (<0.15W)
- wide supply voltage range of 10÷27V DC
