PROGRAMMING WITH THE EASY CONTROLLER
Programming the stroke and movement times
The Easy 4-channel shutter actuator 6 A uses two settable time options to handle the
transitional shutter positions and the power cut-off to the motor.
• Stroke time, which is the time required for the shutter to close entirely from a
completely open position;
• Movement time, equal to 110% of the stroke time, which is the safety time after
which the power to the electric motor is cut-off.
The stroke time is memorised on the actuator following the procedure below:
1. Open the shutter completely ("all UP").
2. Simultaneously press the 2 local command push-buttons relating to the channel to
be set (figure A).
3. Within 5 seconds (before the LEDs stop flashing) press the DOWN push-button to
lower the roller shutter and begin the time count.
4. When the shutter is completely closed ("all DOWN") press either of the local command
buttons to memorise the stroke time then exit the setup procedure.
Make sure you press the button as soon as the shutter is completely closed in order
to memorise the correct stroke time.
In the "Venetian" mode a number of steps can be managed which are needed to
completely open or close the slats.
The number of steps is stored with the following procedure:
1. Move the slats into the completely open position.
2. Press simultaneously the 2 local control push-buttons of the channel to set (figure A).
3. Within 5 seconds (before the LEDs stop blinking) press the UP push-buttons the
number of times corresponding to the number of steps to adjust the slats.
4. When the 5 seconds have elapsed, the UP LED blinks the number of times
corresponding to the value stored.
