Controller has four optical channels and redundant Output Signal Switching Devices (OSSDs). PICO-GUARD Optical Elements Interlock Switches, Points and Grids provide multiple guarding solutions in one system. They have no electrical connection and function either as emitters or receivers, depending on their connection to the controller. This minimizes the required component inventory and simplifies installation. Optical elements are designed to meet the requirements 1 for safeguarding in potentially explosive environments The PICO-GUARD Fiber Optic Safety System combines (controller must be isolated or located outside of the photoelectric and fiber optic technologies to efficiently volatile area). solve a variety of safeguarding applications: Diverse-redundant, self-checking design to achieve Monitoring machine access doors and gates control reliability and meet IEC 61496-1 type 4 and Entry/exit (work cell access) guarding ISO 13849-1 (EN 954-1) Category 4 requirements Short-range perimeter guarding (approvals pending). Multiple fiber optic beam solutions for custom guarding applications Accessory interface module available for ac or larger dc loads. At the heart of the system is the controller: a diverse- redundant, microcontroller-based photoelectric device Optional remote display module available. designed specifically for use with plastic fiber optic Each PICO-GUARD Fiber Optic Safety System requires a cable.* In addition, the system incorporates a number of controller, optical fiber and one or more pairs of optical optical elements, including plug-on, snap-lock fiber optic elements. Controllers include the System manual and safety interlock switches, fiber optic grid arrays, and controller mounting hardware. single-point beam devices. The controller has four separate optical channels. Each channel produces pulsed optical signals that travel through the plastic fiber optic cable, through one or more optical elements, and ultimately back to the controller. Each of the controllers receiver circuits monitors its specific signal to verify that its channel is in the safe state. If a person blocks one of the beams in a grid array or opens a door being monitored by the system, the optical signal is blocked and does not return to the receiver. The absence of this signal is detected and the solid-state safety outputs switch to their off state, which stops or otherwise prevents the dangerous motion. * Patents Pending 1 Approvals Pending Banner Engineering Corp.
