Monitors and Controls the Yarn Length of up to 300 Spindles. This Innovative, Economical and Reliable Product is configured in Master-Slave format, where the HMI is the Master Control Unit (MCU) which sends & receives the control data to the Slave Cards over a 3-Wire Serial Communication Port. Each Slave Card connects to 10 nos of Yarn Delivery Sensors and 10 nos of YarnCutters. The Slave Cards count the input pulses received from the yar Delivery Sensors, and, convert it to length. When the Set Length is achieved, the corresponding Yarn Cutter is actuated to cut the yarn
