WindowMaster Special Technology
The drives are equipped with MotorLink™ technology.
They can be intelligently used with WindowMaster MotorControllers and communicate with standard KNX or LON BUS systems. The drive can be used as a standard ± 24 VDC or controlled as an integrated element of the NV Advance™ or NV Comfort™ solution from WindowMaster.
The chain drive can also be programmed after installation to match specific needs, such as speed, noise, or tensile and push force.
If 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 upon resistance during closing. The setpoint for when the drive should reverse can be individually adjusted.
Additionally, other external systems, such as motion sensors or contact strips, can be connected to the drive.
