The C 4000 safeguards personnel and machines in automated production areas and optimizes work processes. The C 4000 system is used vertically, horizontally or diagonally for safeguarding areas with potential hazards to personnel or equipment. With a flexible design to fit all applications, the C 4000 is simple to commission, maintain and very easy to use.
Efficient and Cost-effective Solutions

• Flexibility. There is a C 4000 system for every application, from the simplest to the most advanced.
• Simplified machine integration and lower wiring cost. There is no need for additional safety relay modules since controls are a part of the light curtain solution.
• Advanced functions, self-diagnostics, E-stop, and reset controls all integrated into the light curtain.
• Universal interface. Every C 4000 Safety Light Curtain works with all interface and control architectures: from relay and safe PLC control to safety field bus.

Benefits of C 4000 System

• Monitoring of receiver cable along entire length through the semi-conductor outputs of the safety light curtain
• Direct connection of Emergency Stop and Reset control units to the C 4000
• No need for separate Emergency Stop and light curtain safety relays
• Uniform diagnosis and configuration
• Less control cabinet space required
• Lower wiring costs
• Easier engineering, as fewer components are required
• Reduced inventory costs, as fewer components are required

Customary savings per machine - minimum $200 Savings per 100 machines - minimum $20,000

Safety and Availability

• State-of-the-art technology. Type 4 third-party certification in accordance with ANSIjULjlECjEN 61496-1, -2. The C 4000 is the first safety light curtain that is also third-party certified to IEC 61508.
• Maximum availability. Shorter downtime through local diagnostic indication (seven-segment display). Beam coding minimizes optical interference from machines in close proximity.
• Seven-segment display: alphanumeric display panel can rotate 1800•
• Fastest response time in the industry. Improved safety and productivity. Shorter safety dis­tances, less floor space.
• Complete suite of advanced functions. Comprehensive and flexible blanking configurations, reduced resolution muting.
• Flexibility. With resolutions of 14 to 40 mm, and protective heights from 150 to 1800 mm, the system can be applied to most safety applications.

Engineering and Maintenance

• Rapid installation and commissioning. Software configurable with CDS software from SICK. Simplified alignment at short and medium ranges. Preconfigured versions available so that no software is required.
• Easy integration, low wiring cost. Cascadable design, up to 3 linked protective fields are possible with one output signal. Installation of up to 3 m cables between sensor pairs.
• Simplified machine integration. Small, compact design. No additional control unit required. Advanced functions, self-diagnostics, E-stop and reset controls are all integrated in the sensor.
• Shorter refitting times. Selectable user-modes (with UE 402) reduce re-tooling times and shorten downtime during operating mode changes. "Real time" user-mode changes.
• Teach-in blanking. Simple teach-in at the press of a button to shorten tool change times and greater availability.
• Simple mounting and adjustment. Corner mirrors and protective screens reduce repair and maintenance cost.

Operational

• Reduced inventory. All-inclusive solution, less parts to stock.
• Universal interface. The same light curtain can be used with all interface and control architectures: from relay and safe PLC control to safety field bus.
• Cost-effective integrated safety platform.
• Common software platform with scanners, bus nodes, etc.
