[. . . ] check shutter or sun-blind system regularly for signs of wear and damage. Damaged systems should not be used under any circumstances until such time as they have been repaired. observe shutter or sun-blind system carefully whilst in operation. Switch off shutter or sun-blind system and disconnect from mains supply, if any servicing or cleaning has to be done either on the system itself or in its immediate vicinity. [. . . ] pLEASE READ THROUGH THE FOLLOWING INSTRUCTIONS CAREFULLY BEFORE SETTING THE LIMITS. Press the DOWN / UP button (remote control or switch) and let the shutter drive move in a downward direction until it cuts off automatically and then (and only then!If necessary make final adjustment with adjustment screw. If it switches off too early the bottom adjusting screw must be adjusted in the plus direction. Each full turn of this screw extends the travel path by about 40° of one turn of the motor. The motor should stop just a few inches below the window frame. If not the adjusting screw should be adjusted in the minus direction. After this the drive must be driven back a little and then up again to check the result. It is possible that the drive will switch itself off after several trips because it has reached a temperature which is too high. Howevere after 15 ­ 20 minutes cooling time it will be ready to operate again. Please note that the limit switches of the drive only function properly if the drive has been installed correctly and is completely within the shaft. Once again the drive moves 2x briefly as a signal that the command has been understood. 2 seconds are allowed as otherwise the process will be stopped. However, the drive must have halted beforehand. Note 3: Don't press a new button before the LED on the remote control has gone out and the drive has stopped moving. Should the drive run in one direction for a long time rather than a short time (between Step 2 and Step 3), the process hasn't worked. Disconnect the power supply to the drive (at least 10 seconds) · press and hold the STOP button on the "master" remote control · Re-connect the power supply now, wait and keep pressing and holding the button. 15 seconds the drive should turn briefly as a signal that it has understood the command. It also determines the direction of movement and decides whether the upper button is actually responsible for UP functionality or the opposite. Even if all that needs to be programmed is a reversal of direction of movement, all remote controls that have been programmed must still be deleted first (see Deleting with and without remote control). PLEASE NOTE: If the reason for reprogramming was that the buttons on the remote control worked the wrong way round (DOWN/UP), press the DOWN button in the following (only applies to new drives with default programming). Press and hold UP button or DOWN button (direction of movement) on the new "master" remote control (stay within radio range of drive) · Re-connect power supply and wait · If it has worked, the drive turns 2x briefly as a signal that the command has been understood. [. . . ] The motor is not getting sufficient power because of a poor feed cable. Only operate one switch with one motor or use an isolating relay (accessory). The fuse was overloaded due to the operation of several motors with isolating relays. The drive has too much axial play (shaft). [. . . ]
