EZ-Screen Safety Light Screens - BANNER ENGINEERING - #9

■p

Objective: Safeguard the access point of a workcell while allowing material to enter or exit, but preventing exposure to hazards by personnel. Sensor Model: SGP4-300Q83 EZ-SCREEN Grid, set for Trip Output, interfaced with a MM-TA-12B IP67 Muting Module, Q45 sensors used as muting inputs, set for Latch Output.

Operation: The EZ-SCREEN Grid is configured to allow material to pass through Ihe sensing field without having to be manually reset. The MM-TA-12B evaluates signals from the EZ-SCREEN Grid and mute sensors to determine whether to send a stop signal to the machine control or not. If something or someone is inappropriately entering the workcell, the hazardous motion is stopped. The MM-TA-12B must be manually reset before operation can resume.

Objective: Safeguard a robotic welding cell.

Sensor Model: Four systems of the cascade EZ-SCREEN SLSCP30-1800Q88 Operation: Two or four systems of EZ-SCREEN are cascaded (daisy-chained) to form "L" shaped sensing field(s). This configuration minimizes separation (safety) distance and pass-through hazards by providing continual sensing as an area guard. All four systems can be cascaded together, or separated for individual muting applications. E-stop buttons can be incorporated at the end of the chain if muting is not incorporated.

Objective: Protect the operator and other factory personnel near a large press that uses Two-Hand Control for cycle initiation and muting of the Safety Light SCREEN.

Sensor Model: 1800 mm EZ-SCREEN pair, 30 mm resolution (set for Trip Output operation) interfaced with STBVR81 Self-checking Optical Touch Buttons and an AT-GM-11KM Two-Hand Control safety module with muting. Operation: The EZ-SCREEN is angled to prevent a pass-through hazard and maintain separation (safety) distance. The EZ-SCREEN solid-state safety outputs supply power to the STBVR81 touch buttons, such that if the light screen is interrupted the Two-Hand Control can not be actuated. Once the sensing field is clear, the STBs become functional, which allows the operator to begin the cycle. Once the die closes, both the EZ-SCREEN and the STB Two-Hand Control are muted, allowing the operator to accomplish other tasks while the machine cycle is completed. (Call factory for further information.)

SEMICONDUCTOR WAFER MANUFACTURING CELL

Objective: Totally safeguard a manufacturing cell, including E-stop buttons, interlocked guarding, and a safety light screen.

Sensor Model: An SFCDT-4A1C PICO-GDARD™ controller is interfaced with an SLSP14-900Q88 EZ-SCREEN, set for Trip Output, and a string of E-stop buttons. Operation: The PICO-GDARD controller is optically monitoring all interlocked guards to a Category 4 safety level. The PICO-GDARD is also monitoring safety signals from an E-stop string and the EZ-SCREEN. The EZ-SCREEN is configured for automatic reset, while recovering from an emergency stop situation must be manually reset before operation can resume.
