If you are a CORRUGATOR OPERATOR i ask you what are the diferences between the automatic machine and manual machine?

a manual machine is one that involves much human activities in its operation.the parameters are set manually and monitored by the operator.technically its an open loop system........an automated machine has the machine in a closed loop system and requires no or little operator interference.the parameters once set are adjusted automatically as operations proceed.when an error occurs,it is as shown on the HMI..........................i hope you have been answered well.
