PROGRAMMING THE STROKE AND MOVEMENT TIMES
The motor command actuator 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. At the same time hold down the 2 local command buttons (figure A): the
LEDs will flash.
3. Within 5 seconds (before the LEDs stop flashing) press the DOWN button
and lower the shutter.
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.
