GuardShield™ Type 2 Safety Light Curtain Installation Instructions Introduction The GuardShield Type 2 safety light curtain is a general purpose presence sensing device, designed for use on hazardous machinery providing point of operation, as well as, perimeter and access detection. It is a self-contained, two box, Type 2 ESPE (Electro Sensitive Protective Equipment). The GuardShield Type 2 is offered in either guard only mode or with a restart interlock and EDM.
GuardShield™ Type 2 Safety Light Curtain Installation Instructions Range of Uses of the Device The GuardShield Type 2 safety light curtain is classified as electrosensitive protective equipment (ESPE). The physical resolution is 30 mm (1.18 in.). The maximum protective field width is 18 m (59 ft) for the 30 mm (1.18 in.) resolution GuardShield Type 2. The protective field height is between 160 mm (6.3 in.) and 1760 mm (69.2 in.).
GuardShield™ Type 2 Safety Light Curtain Installation Instructions GuardShield Type 2 is factory ordered with this functionality. Indication of this mode of operation is through illumination of a yellow LED on the GuardShield Type 2 receiver. Restart Interlock Figure 1: Components of the GuardShield Type 2 The upper and lower limit of the protective field is shown by markings on the housings.
GuardShield™ Type 2 Safety Light Curtain Installation Instructions IMPORTANT machine’s control circuit and any other devices that react to stop the hazardous motion of the machinery. Not including the response time of a device or devices in the stop time calculation will result in insufficient safety distance for the application. This may result in operator injury. Determining Stop Time: The measurement of stopping time (Ts) must include the stopping times of all devices in the stop circuit.
GuardShield™ Type 2 Safety Light Curtain Installation Instructions • Resolution of the light curtain and/or beam separation. Minimum Distance from Reflecting Surfaces The infrared light from the sender may be reflected off of shiny surfaces and be received by the system’s receiver. If this condition occurs, it can result in an object not being detected when it enters the GuardShield Type 2 sensing field. Safety distance S (Ds) All reflecting surfaces and objects (e.g.
GuardShield™ Type 2 Safety Light Curtain Installation Instructions The effective aperture angle for the GuardShield Type 2 system is within ±5.0° at a mounting distance of > 3.0 m (9.8 ft). Calculate the minimum distance to reflecting surfaces depending on the distance between the transmitter and the receiver, using an aperture angle of ±5.0°, or take the appropriate value from the following table: Distance Between Transmitter and Receiver (Range X)D [m (ft)] Minimum Distance a [mm (in.)] 0.2…3.0 (0.
