STR-4D 12/24V roller shutter controller for DIN rail F&F

Operation

The controller for opening and closing roller shutters can work as a stand-alone device (designed to control one roller shutter), as well as it is possible to combine controllers into groups, allowing central control of multiple roller shutters. The shutter motor is activated by momentarily applying a + signal to one of the control inputs. The motor is switched on for the time programmed by the user, allowing the shutter to be fully covered or uncovered. Power supply to the controller is signaled by the lighting of the green U LED. The operation of the motor and the direction of the roller shutter movement is signaled by the lighting of the corresponding red LED or . It is possible to stop the running roller shutter at the level selected by the user (partially covering or uncovering the roller shutter).

Control

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

Local control
Depending on the way of connection, the roller shutter 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 time 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 the + (plus) line. 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 activate the roller shutter in the opposite direction to the previous one.

Central control
The controller always cooperates with two inputs of the central control.
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 1.5s, the motor will start to work in the opposite direction.
The time of switching on the roller shutter in the central control can be randomly delayed (by a maximum of 1s) - 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 to close and lock 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 control panels
alarm panels
-direction memory
for local and central control. If the controller executes the command Central -
up, the next press of the local button will operate the roller shutter downward
-asynchronous start
the roller shutter activation time in the central control is randomly delayed (maximum
by 1s) in order 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
