WindowMaster Special Technology
The drives are equipped with MotorLink™ technology.
They can be used intelligently with WindowMaster MotorControllers, and communicate with standard KNX or LON BUS systems. The drive can be used as a standard ± 24 VDC or as an integrated element of WindowMaster's NV Advance™ or NV Comfort™ solution.
The chain drive can also be programmed after installation to meet specific needs – for example, 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 pinching can be reduced, as the drive can be programmed to stop and reverse upon encountering resistance during closing. The setpoint for when the drive should reverse can be individually adjusted.
Furthermore, other external systems such as motion detectors or contact edges can be connected to the drive.
