The five is the main machine stop signal is not recovered. The countermeasure: check the press air check signal(the pressure signal more than 0.4MPa must be send to the PLC, namely, does the I8.0 has the signal, if the I8.0 still has no the signal, you shall check the electric contact pressure gauge adjustment is normal or broken until there is the I8.0 signal. You shall check that the mixer maintenance protective switch signal is sent to the PLC, the I9.7 the signal, and then check emergency stop switch is properly reset, I0.1 the signal. 4, next, check that the main power switch is switched on, the I3.4 the signal. Finally, check out button is reset and the I5.2 is switched on.
