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