1 File No. L90200 Description BeamSafe Long-ange, Single-Beam Safety Control 200 foot (60 meter) range Four possible transmit codes eliminate crosstalk from multiple units in the same area Signal strength indicator and integral Gun Sight allow easy installation No interconnecting cables required, which speeds longrange installations Three models available: elay output with 24VDC power input elay output with 85 to 250 VAC power input Solid-state output with 24VDC power input Switch selected Automatic Start or Start/estart Interlock operation Lens heater Shown here with optional quick-disconnect cable kit. The STI BeamSafe is a longrange single-beam safety control designed for perimeter and access guarding. Diverse redundant microprocessor design provides safe, control reliable operation. A BeamSafe system consists of one transmitter and one receiver. No interconnecting cables or separate control enclosure are required. Mounted on the receiver, four separate visible indicators provide instant information on system clear, blocked or interlocked status as well as signal strength. Additional diagnostic indicators on the receiver provide codes to assist with trouble shooting. Output options include redundant solidstate or force-guided relays located in the receiver. Immunity to weld flash and ambient light are enhanced by coding the infrared beam. This feature also eliminates interference from other BeamSafe units installed in close proximity. A tight beam angle reduces problems associated with reflective surfaces. The Beamsafe s builtin lens heater is effective in environments where condensation may form on the transmitter or receiver lens. Adjustable mounting brackets allow easy alignment Designed in accordance with IC61496, N954-1 and ANSI B11.19 C108

Never use a BeamSafe on a full-revolution clutched press or machine. The BeamSafe is a single optical beam, not a curtain of light. Therefore it is not designed for use as a point-of-operation device. If one or more BeamSafe systems do not protect all access to the hazardous machine area, the unprotected access must be guarded by fencing, barriers or other appropriate methods. The purchaser, installer and employer are responsible for meeting all appropriate laws, rules and regulations relating to the proper use, installation, operation and maintenance of this control and the guarded machine.

5 Custom Modifications Custom Modifications For Safety Light Curtains Custom Modifications STI offers a wide range of safety light curtains. The correct curtain for your application is probably in this engineering guide. If it isn't, contact our engineers to discuss your requirements. STI has an established reputation for creating custom modifications of standard products. Some examples are highlighted below. SD-safe Modification Versions of several STI safety light curtains are available for use in areas where it is important to dramatically reduce electrostatic discharge. The curtains have been tested to the standards of the OS/SD associations. Triboelectrification and static charge are well within the required limits. Consult STI for test results. High Temperature Fiber Optic Light Curtain STI can modify our standard MiniSafe MS4400 safety light curtain so that each individual beam is presented by a fiber optic cable. This allows the transmitter and receiver electronics to remain safely out of the high temperature area. Controller Quick-disconnect Certain applications call for to have double-ended quick-disconnect cables. This custom modification is available from STI. Quickdisconnect cables are available for transmitter, receiver, input power and relay output connections. MiniSafe Quick-disconnect Cables LD Indicators MiniSafe Film-safe Safety Light Curtains When used in a photographic film production facility, the infrared light normally emitted by will fog the film and spoil production. STI has designed with no visible indicators and "film friendly" infrared light. C130
