| Abstract: | Considering the characteristics of bundle dryer, an auto-control system for the fan which serving three bundle dryers through the frequency conversion was designed. The system which employs S7-300 PLC and STEP 7 software has mechanical and logic interlock function to ensure both safe and reliable operation and to realize auto- mation of the production and the energy saving so that the work efficiency of the drying unit can be improved. |
