The advanced control solutions can provide millimetre-by- millimetre control of the actuators. Accurate positioning of windows is necessary to obtain an optimal indoor climate during all seasons and all weather conditions. Data communication between the actuators and the MotorControllers enables the actuators to report back their precise position. This enables the BMS system to know the exact position of the vents at all times.
The registration of the exact position of the windows enables the BMS system to accurately position the windows to ensure that they are open to the same amount which maintains the external appearance of the facade. This also prevents the BMS system having to close the windows at numerous times during the day in order to reset their position to the fully closed position, preventing so called “hunting” of actuators is also a benefit of this feature.
The WindowMaster actuators equipped with the special MotorLink® technology enable different opening/closing speeds to be used, dependent upon the digital command received. For instance a slow and soundless speed when in automatic mode and a faster more audible speed when activated by the manual keypads in order to provide an immediate visual response to the user. This technology makes it possible to operate automatic (slow speed and soundless) during lessons in schools, meetings etc.
The MotorLink™ actuators can run fully synchronised – without an external synchronisation module. Up to four actuators can work together on one window with a tolerance of less than 2 mm. Through our patented solution the actuators communicate with each other directly and adjust their speed so that they are always operating fully synchronised. This genuine real time synchronisation is the best guarantee that the window is not, for example, damaged by actuators running at different speeds.
The WindowMaster actuators include an integrated reversing function, which enables the pressure on the window gaskets to be released by a few millimetres after the windows have been closed. This ensures a prolonged life span of the gaskets and air-tightness of the window. The distance which the window actuators reverse can be programmed individually for each window and adjusted after installation if required. The reverse function ensures that the windows gaskets are not destroyed by the closing force of the actuator.
Window actuators equipped with the special MotorLink® technology can reduce the risk of entrapment. The actuators are programmed to stop and reverse if they encounter obstacles when closing. The set points determining when the actuators are to reverse are adjustable, but there is a limit to how sensitive they can be set as they still need to overcome the forces required to close and seal the window. In addition, other external systems can be linked to the actuators, e.g. motion sensors or safety edges. This safety function reduces the risk of anything becoming trapped in the window.
Actuators from WindowMaster using the special MotorLink® technology include a two-way communication between the MotorController and the individual window actuator. Feedback from every window actuator can provide an early indication of any potential faults. This feature makes it very easy for the caretaker or facilities manager to locate any fault in the system.
Online parameter set-up, either from a maintenance terminal in the building or remotely via the internet or modem, is a standard feature in all MotorLink® solutions. Therefore initial set-up and future adjustments to the speed and forces etc. of the actuators is quickly and easily achieved. The on-line parameter set-up greatly reduces the hours needed for commissioning the system.
