Some solutions, likeВ Somfy RTS wireless, can only be interfaced using a proprietary gateway which will have an interface such as RS485. It is also a more cost-effective solution when multiple fittings are to be controlled simultaneously, since multiple fittings can be controlled.

With this method, it is possible to control the blinds more accurately as the on-board controller can determine the positioning instead of guessing with the run time.Д®nvironmental conditions and individual motor performance can affect the run time of fittings, but as a digital control will overcome this, it is the only solution if accurate positioning or hem alignment is required. This could be a standardised solution such as an SMI (Serial Motor Interface) or a propriety solution such as SomfyвЂ™s Digital Network. Like contact closures, some blind motors have an embedded controller that can receive the move and positional commands via a digital interface. This makes it possible to close both outputs simultaneously for the stop command. KNX blind controllers are designed to directly control the motor and so it is advisable to use standard relays with blinds or curtains that have their own on board controller. Most of these blinds require a short pulse on an open or close input and a pulse on both to stop. In this case, control is via contact closure which triggers the on-board controller to start the motor in the appropriate direction. In the same way as 230v it is important to wire each blind to an individual channel ensuring there is no erroneous feedback or operation of the blinds.Д¬ertain manufactures have a controller embedded into the motor or fitting. Most 24VDC KNX blind actuators will do this automatically, but require a separate Power supply to provide the 24VDC feed. To control DC motors the polarity of the DC feed to the motor is reversed. This can cause each motor to feedback in a cycling loop, causing irrevocable damage.ДC motors can be smaller and quieter than the equivalent AC motor so they are particularly common in high end residential applications.

Only one of the directions should be powered at any time which is achieved with a software interlock on two standard relays or by using a dedicated blind controller which will have a relay that provides the interlock.ДЄlthough itвЂ™s convenient to put multiple blinds on the same channel, this needs to be avoided due to the potential for feedback from one motor once the end stop is reached. KNX offers a control solution for every type of curtain and blind motor however as the amount of control can vary it is important to understand the difference so you can guarantee the end result.Дў30VВ motors have a phase (live)В for each direction of travel along with a common (neutral).

This is a good option if the fitting is likely to be changed by the customer or if slightly more accurate positional control is required. Some control actuators also use current detection to determine when the fitting has reached its limit. This is achieved by defining the run time of the fitting in the parameters of the actuator via ETS. This can be relied on to stop movement however the KNX actuator will still need switch off a short time after. Most curtain and blind motors will have an integrated limit switch which stops movement when the limit of travel is reached. KNX actuators are referred to as blind actuators however they can also be used for all types of shading and window control including curtains, louvers, window motors, venetian and roller blinds Automating blinds and curtains offers a range of benefits from making the building more comfortable to reducing energy and even time saving.
