The other canopy motor s i. A retractable awning hhalcomaster claimed in claim 6, wherein at least one of the motors is arranged to drive one or more end units along one or more of the tensile wires. A control unit may control the storage roller motor and at least one of the canopy motors e.
Halcomaster 2200 Gebruiksaanwijzing
Other arrangements will work equally well. A retractable awning as claimed in claim 6wherein one first motor is provided for each tensile wire.
As mentioned above, the other canopy motors may adjust their position relative to the master motor. This receives motion commands from the master PCB 60 and controls motor 9 S in response to these commands.
Also, the tension required to maintain a large screen sufficiently taut at such a reduced angle is prohibitively large. This can cause unbalanced pulling forces to be applied to the screen which can consequently be deployed and retracted in a lopsided fashion. The roller system comprises two rollers 7 a7 b. While in position mode, the current loop command is limited to be in a range that will not force an undesired moment against the AC motor 35 beyond that required to keep the awning taut.
The controller 6454 of each end unit 2021can implement a number of different modes. Master local controller 64 also receives information regarding the velocity of the storage roller, and determines the drive velocity of the roller halcomasetr in accordance with this so that the storage roller and end unit velocities remain synchronised, and so that the screen is maintained under appropriate tension during retraction. Thus, viewed from a further aspect the invention provides a control system for halcomsster extension and retraction in 22000 retractable covering apparatus, wherein the control system comprises: Data cable 42 is threaded through halcomasteg screen 2 from motion control unit 30 to master end halcomster Electromechanical sun visor for motor vehicle windows.

Search Expert Search Quick Search. In a deployed state, if an end unit moves so that tension is reduced, the control system will output an appropriate control signal to that end unit driving motor to drive the end unit back to the correct position so that tension is returned. Halcomaster Gebruiksaanwijzing – 2, related keywords.
These tensile wires are splayed apart so that they become further apart in the direction of extension of the screen. Also the motors may provide different drive forces, for example due to manufacturing tolerances or, variations in the power supply may cause one motor to pull momentarily stronger or to suffer a lull.
This feeds a motion control PCB 34 which is part of the motion control unit and also a master end unit 20 as described in more detail below. A retractable awning as claimed in claim 12, wherein each motor operating an end unit is arranged with the end unit and moves therewith.
Further tension can be applied by e. Apparatus for opening and closing a flexible screen in a greenhouse or the like. The cables 4 of this embodiment are splayed apart in the direction of extension of the screen 3.

Window roller blind or partition net with two angular gears. In order to extend the screen, the clamping systems are released and pulled along the wires, thereby extending the screen with respect to the wires. A control unit may control the storage roller motor and at least one of the canopy motors e. A retractable awning as claimed in claim 17, wherein the storage roller is driven by the second motor. If a discrepancy is detected, the speed of one or more of the motors may be adjusted in order to compensate and bring the tension back into line.
Hlcomaster retractable awning as claimed in claim 1further comprising a sensor for sensing tension in the screen. It also sends halcomxster motion commands to the halfomaster end unit 21 over an RS communications channel via a data cable 57 and respective connections 62 The position of the screen can be monitored by means of rotary encoders as described above.
Not only does this make the screen less effective, but it can damage the screen. By coordinated or synchronised, we mean that the motors are operated so that they maintain even tension in the screen. For example the maximum velocity of the master motor during extension may be halcomasger at the velocity of the storage roller. A retractable awning as claimed in claim 1, wherein the first motors are attached to the screen.
In a deployed state, if an end unit moves so that tension is reduced, the control hzlcomaster will output an appropriate control signal to that end unit driving motor halcomaaster drive the end unit back to the correct position so that tension is returned.
This allows the pole 18 to withstand a greater force. The present invention relates to a retractable covering apparatus such as a canopy or awning, having a control unit for controlling the extension and retraction thereof.
Further embodiments of the invention will now be described with reference to FIGS. Any differences will be described later. In a most typical arrangement of the invention there will be provided an extendible canopy disposed on a storage roller e.
