WindowMaster Special Technology
The drives are equipped with MotorLink™ technology.
They can be intelligently used with WindowMaster MotorControllers. Communicate with standard KNX or LON BUS systems. The drive can be used as standard ± 24 VDC or as an integrated element of the NV Advance™ or NV Comfort™ solution from WindowMaster.
The chain drive can also be programmed after installation to meet specific needs – e.g., in terms of speed, noise, or tensile and compressive force.
When the drive is used as a MotorLink™ drive in an NV Advance™ system, the risk of entrapment can be reduced, as the drive can be programmed to stop and reverse against resistance during closing. The set point for when the drive should reverse can be individually adjusted.
Furthermore, other external systems can be connected to the drive, such as motion sensors or contact strips.
