The Ambi-room electric auto-control system of final Optics Assembly

This control system adopts Siemens S7-400 PLC to realize these functions of monitoring ambi-room pressure by the vacuum gauges and manipulating all vacuum valves in real time etc. The ambi-room control system belonged to unworthy man guard equipments has severe control request of "absolute safety", so that it must ensure safety and credibility in every operation flow: vacuum achievement, input dry clean air, keeping ambi-room pressure, dynamic state purge air sweeping etc. So safety design and manufacture is preferential to any other request, furthermore this idea passes through all control workflow. Because the user mutual interface is very friendly, the manipulation is simple and easy to learn for all assigned operators.
