FF-LS30 FEATURES * Meets applicable parts of US OSHA 29 CFR 1910.217, 1910.212 and ANSI B11.1, B11.2, B11.19 1990 and RIA 15.06 regulations for Control Reliability * EC type examination certificate granted by the TUV * Designed in compliance with the IEC/EN 61496 - parts 1 & 2 for Type 4 Electrosensitive Protective Equipment (permanent self-checking equipment) * Through-scan small profile sensing unit with separate control unit * Minimum object detection capability: o30 mm / 1.18 in suitable for hands detection * Scanning range: from 0,2 m up to 3,5 m/ 0.65 ft to 11.48 ft * Protection heights: from 236 mm up to 1804 mm / 9.29 in up to 71.07 in * Global response time: less than 50 ms * Power supply voltage: 24 Vac/dc * Outputs: 2 guided contacts safety relays * Test input * Automatic restart or start & restart interlock * Sealing: IP 65 (sensing units and control unit) * Immunity to ambient light: 50 000 Lux max. FF-LS30 Series The permanent self-checking electronic process is based upon a microprocessor technology and meets the requirement of the IEC/EN 61496- parts 1 & 2 European standards for Type 4 electrosensitive protective equipment. It has been examined by the TUV who granted the EC type examination certificate. The equipment consist of a pair of sensing units connected to a separate control unit via a RS-485 connection. Each sensing unit is made of a row of emitting circuits alternating with receiving circuits. These circuits are housed in an extremely small aluminium extruded profile: the cross section is only 12 mm x 19,7 mm / 0.47 in x 0.77 in. The two sensors are matched to each other by individual coding to reduce risk of cross talk with other light curtains and to improve immunity to welding splashes. The control unit supplies the sensing units, controls the correct operation of the scanning circuits and transmits the resulting commands to the machine control circuitry through its two relay outputs. The equipment can operate according to two different mode: the automatic mode, the start & restart interlock mode. In addition, the control unit is featured with a test input to trigger the output relays switching and thus check the correct operation of the final switching devices whenever needed. In case of failure, the control unit provides optical and acoustic signals to ease failure diagnostic. !

For the safety distance, the following formula applies: Safety distance S * Normal approach H Europe (EN 999) S 2000 (t1 + t2) + 128 (mm), with S 100 mm (or S 78.8 t1 + t2) + 5 (in), with S 3.9 in P If the result of this calculation is greater or equal to 500 mm / 19.7 in, then use the following formula: S 1600 (t1 + t2+ 128 (mm), with S 500 mm (or S 63 (t1 + t2) + 5 (in), with S 19.7 in US (OSHA 29 CFR 1910.217, ANSI B11.19 1990 Ds 63 (t1 + t2) + 3.08 (in) Ds = S S * Parallel approach H If H is greater than 300 mm / 11.82 in, the risk of access from below must be taken into account. For this barrier, the minimum height allowed is H min. = 0 mm and the maximum height allowed is H max. = 1 000 mm / 39.4 in. S * Angled approach FF-LS30 Europe (EN 999) S 1600 (t1 + t2) + (1200-0.5H) (mm) where (1200-0.4H) 850 mm (or S 63 (t1+t2) + 47.3 - 0.4H0 (in) where (47.3 - 0.4 ) 33.5 in) P H Europe (EN 999) 30 < < 90 If the angle is greater than 30, the approach should be considered as normal, and one of the above-mentioned formulas should be used. 0 < 30 If the angle is less than or equal to 30, the approach should be considered as parallel and one of the above-mentioned formulas should be used. In this case the minimum height allowed is P min. = 0 mm and the max. height allowed is H = 1 000 mm / 39.4 in max. However, if P > 300 mm / 11.82 in, the risk of inadvertent access from below must be taken into account.
