Adjustments according to the operating forces. Without 0-1 connection to the BRAKE card and
DIP5=OFF. Perform the following steps:
- Set the trimmer VC=MAX. Adjust the correct closing speed as indicated in paragraph 6.7 and
ensure that the manoeuvering force and the thrust between the door and the obstacle is lower
than the values set out by regulation DIN 18650-1.
- Reduce the trimmer VC adjustment and perform the opening and closing manoeuvers. Repeat
this step until you find the VC trimmer position that causes the POWER ALARM LED to light
up.
- Increase by approx. 20% the VC trimmer adjustment.
TC Automatic closure time. It adjusts the time that elapses between the ending of opening control
and the beginning of the automatic closing. Time is renewed by controls 1-3A, 1-3B, H-3A, H-3B
and 41-8.
RF Motor torque. It adjusts motor torque.
RF trimmer also adjusts thrust on obstacles.
If an obstacle is present, during opening operation it stops movement, whereas during closing
operation it reverts movement.
After the obstacle has been removed, the door automatically searches for its stop and continues its
stroke at learning speed. If an opening control is given with the door locked, the following opening
operation will be disabled for 30 s.
