4.3 Carton Tunnel Controls
Control would be by an Allen Bradley CompactLogix PLC, located in our MCC.
Manual control would be provided by means of two pushbutton stations mounted in positions to enable the operator to observe the operation selected.
Station 1 - Transfer end of tunnel
Station 2 - Load/Unload end of tunnel
The control system is a fully integrated 24 volt D.C. system. All safety interlocks will be operational when control is switched to manual mode.
Operator Interface is an AB Touch Screen (10”). The tunnel sequence can be followed via graphic displays and fault status indications
