3 Product and installation 3.1 Main components for installation rapidly. Signal quality should always be 100% for satisfactory function. The robotic system involves 4 main components: • Product • Charging station • Power supply • Loop wire Go to the manufacturer's website or read the Operator's manual for further descriptions about the product and 15 m/49 ft.
3.7 Sensors always goes from the guide wire to the left in the connection between guide wire and boundary loop. There are several types of sensors in the product: The strength of the guide signal varies like the A signal depending on the distance to the guide loop.
® smart SILENO life and Lawn shield for McCULLOCH are the same function. This function is not available for ® the Husqvarna model. When SensorControl/Lawn shield is activated, the product automatically adjust its mowing times based on how fast the grass grows. This is decided by continuously measuring the blade disc resistance and comparing that to a mean value.
