var s="The KTI 6120 & 6130 series Safety Light Curtains when used alone can only protect one side of a press or machine. However, some application may require additional sides to be guarded. Refer to Fig-1 for two side guarding configuration. For additional sides auxiliary mirrors are added to redirect the safety beam. Note a 10% energy loss per mirror should be considered when determining perimeter-guarding area. Example the KTI 6120 series safety light curtain has a maximum scanning range of 70ft using one mirror (10% loss) the new maximum range would be 63ft.";
