1.Check weigher frequency converter setting 2-00:d1, frequency enter source, by external current 0-10v 2-01:d2, operated by external terminal. Keyboard STOP can work. 4-04:d2,M0: run/stop, M1: forward/reverse 1-00:60 1-01:60 2-00:d1, frequency enter source, by external current 0-10v 2-01:d2, operated by external terminal. Keyboard STOP can work. 4-04:d2,M0: run/stop, M1: forward/reverse 1-00:60 1-01:60   1-09 the first acceleration time [...]

1.Open the cabinet which is on the face of switch as below picture, and find out power supply. 2.Then measure 203+ and 203- by multimeter, valid voltage should be DC24V . 3.If the voltage is 24V, which means the power supply is no problem, the problem will be either screen or the cable which connect between cabinet [...]

Firstly, take down the No.1 aluminum box, find motor position line and measurethe voltage to see whether there is about 18 v DC by a multimeter. If there is no 18 v voltage, open the machine frame that is on the right of the emergentstop button Find out the main board of multihead weigher, there is [...]

Analysis: The thickness of the material directly affects the multihead weigher’s accuracy, thus affecting the actual production accuracy. If the material is too thick ,the phenomenon of excess weight is often present. If too thin,weighing hopper feed for many times so as to affect the rate of combined balance, the weigher’s speed will be slower as [...]
