English : This curtain controller will automatically close the curtain, when it gets dark, and it will open the curtain when it gets light. Normally, you will position the controller left to the left curtain. This controller is connected with a 12 V / 2A adapter to the socket. A (red) network cable is connected to the motor controller on the wall behind the curtain. First operation : Put the switch in the middle, connect the adapter to the contoller and switchh on the controller by connecting the adapter to the wall socket. The yellow led in the middle will flash rapidly at first, then the red and green led will flash 6 times, to indicate controller is active and working. The light outside will be measured and stored. The curtain will stay in its current position. Only when there is a light change from dark to light or vice versa, the curtain will get the appropriate action command. On the controller there are 3 indicator leds and a switch. De leds/light have the following colours, GREEN, YELLOW and RED. The switch has 3 positions : Switch to the left = open curtain (the left curtain goes to left position) Switch in th middle = automatic (DARK will close the curtain, BRIGHT will open the curtain) Switch to the right = close curtain (the left curtain goes to the right position) When you want to close or open the curtain, you can use this switch, regardles the light condition outside. If you want to open the curtain, put the switch to the left. The green light will illuminate. If you leave the switch in this position, the curtain will stay open. Same action applies for the switch to the right (close the curtain). Normal situation will be, that this switch is in the middle. There are no leds/lights lit, and the curtain will act on a light change. The yellow led has little use in this end-product. Depending on the firmware, the light can flash or not. WHEN SOMETHING GOES WRONG ! If the controller senses that the curtain is not closed or opened fast enough, an obstruction of the curtain is assumed. In that case, the controller will flash the red light rapidly, and will continue to do that, until reset (pull the adapter from the socket/ power off). You need to resolve the situation first, before powering on the controller. Most likely, the curtain is obstructed by something, or the belt is broken or loose. Electrically, the used reed switches don't function anymore or the magnets are not in it's (right) place anymore. If the situation is not resolvable or you do/can not use the controller anymore, unhook the curtains from the clips, and hook the curtain to its original attachment on the rail. Make sure that the clips on the belt do not obstruct the movement of the curtain (remove the belt on the whole, or position the clips vertically with some adhesave tape).
