3. USE AND MAINTENANCE
This drive is maintenance-free
3. 1. RAISING AND LOWERING THE ROLLER SHUTTER
Press the "Up" button:
1)
The roller shutter rises and stops at the top stop without
•
requiring adjustment.
Press the "Down" button:
2)
The roller shutter descends and stops at the bottom stop
•
without requiring adjustment.
3. 2. OBSTACLE DETECTION
The automatic obstacle detection function protects the roller
shutter and enables obstacles to be cleared:
If the roller shutter meets an obstacle when lowered, it stops
-
automatically:
Press the Up button to release the roller shutter.
•
If the roller shutter meets an obstacle when raised, it stops
-
automatically:
Press the Down button to release the roller shutter.
•
3. 3. ANTI FREEZE PROTECTION
The anti-freeze protection function operates in the same way as the obstacle detection function:
If the drive detects any resistance, it does not move in order to protect the roller shutter:
-
The roller shutter remains in the initial position.
•
The automatic antifreeze protection prevents damage to the shutter when the last slat of the shutter
is frozen onto the windowsill. However, if the shutter is (completely) frozen in its guide rails or if a
single slat is frozen solid to another, this may reduce the e ectiveness of the antifreeze protection.
In this event, it is still possible that damage may be caused to the shutter. It is very rare for the
shutter to become frozen in this way. In such a case, refrain from using the roller shutter until the
ice has been removed.
