The yarn needs to be under constant tension to be knitted properly. The top tension arm works together with the lateral tension arm. When the tension lowers, the arm pulls up to balance the tension on the yarn.
When the tension in the yarn drops too much, the arm jumps up, the sensor is triggered and the sensor light lights up. It normally refers to a broken yarn, having run out of yarn or incorrect machine settings for the used yarn.
With thinner yarn, the arm needs to pull up less high. To let the arm pull less high, turn the tension adjusting wheel clockwise. For thicker yarn, the pull can be increased by turning the tension adjusting wheel counterclockwise.
