How to Install and set the Limit Switch
Remove the Limit Switch Cover
This cover can be removed after the Somfy motor has been hard wired by a qualified electrician. You can then fully lower the curtain, but you must stop the curtain at the fully down position, with control switch supplied. The limit setting have not been set. How to set the limits is described below. With the curtain lowered you will then be able to see this limit setting cover.
Setting the Up and Down limits

If the direction of movement is correct you can now move on to adjusting the stop limits. If the curtain is moving in the wrong direction to the control point’s indicator of direction, turn the power off, and reverse the brown wire and black wire at the control point.
