GuardShield™ PAC Safety Light Curtain Installation Instructions GuardShield PAC Safety Light Curtain Selectable functions of GuardShield PAC with ArmorBlock Guard I/O connectivity: • Beam coding Introduction The GuardShield PAC safety light curtain is a multiple beam, presence sensing device designed for perimeter or access detection around hazardous machinery or equipment The GuardShield PAC is a Type 4 AOPD per IEC 61496.
GuardShield™ PAC Safety Light Curtain Installation Instructions This Class 1, eye safe laser is switched from a low output power state to a high output power state (and back again) by means of control circuitry which detects reflected laser light from a temporary blockage of the emitted laser light. This is most commonly accomplished by a person’s finger placed over the laser overlay window.
GuardShield™ PAC Safety Light Curtain Installation Instructions • The national/international rules and regulations apply to the installation, use and periodic technical inspections of the safety light curtain, in particular: ♦ Machine Directive 98/37/EEC ♦ Equipment Usage Directive 89/655/EEC ♦ The work safety regulations/safety rules ♦ Other relevant health and safety regulations Manufacturers and users of the machine with which the safety light curtain is used are responsible for obtaining and observing
GuardShield™ PAC Safety Light Curtain Installation Instructions Examples of Range of Use The GuardShield PAC safety light curtain operates as a proper protective device only if the following conditions are met: • The control of the machine must be electrical. • The controlled machine must be able to be stopped any where in the machines stroke or cycle. • The transmitter and receiver must be mounted such that access to the hazard is only through the light curtain’s protective field.
GuardShield™ PAC Safety Light Curtain Installation Instructions The test input must be configured via a dip-switch located in the GuardShield PAC transmitter. Figure 2 is an example of a GuardShield PAC three-beam safety light curtain used as an opto-electronic fence with corner mirror columns. Beam Coding Figure 3 is an example of a GuardShield PAC three beam with four retroreflective sensors and an external muting module.
GuardShield™ PAC Safety Light Curtain Installation Instructions distance between the light beams and the nearest point of danger. Mounting Stand with Corner Mirror Persons situated inside the danger zone, but outside the protection field are not recognized. It must therefore be ensured that a dangerous condition is only possible when there is nobody present in the danger zone. Receiver The relevant legal and government regulations are to be complied with the implementation of protection installations.
GuardShield™ PAC Safety Light Curtain Installation Instructions IMPORTANT Determining Stop Time: The measurement of stopping time (Ts) must include the stopping times of all devices in the stop circuit. Not including all device and control system elements when calculating Ts will result in an inaccurate safety distance calculation.
GuardShield™ PAC Safety Light Curtain Installation Instructions IMPORTANT The TS number must include the response times of all devices, including the response time of the safety light curtain, the safety light curtain controller (if used), the 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.
GuardShield™ PAC Safety Light Curtain Installation Instructions How to Calculate the Safety Distance S According to EN ISO 13855 and EN ISO 13857: ® First, calculate S using the following formula: S = 1600 × (Ts + Tr) + C Where … Ts = stopping/run-down time of the machine + response time of the protective device [s] Tr = response time of the GuardShield PAC S = safety distance [mm] C = safety supplement The effective aperture angle for the GuardShield PAC system is +/2.5° at a mounting distance of > 3.
GuardShield™ PAC Safety Light Curtain Installation Instructions The standard GuardShield PAC has an LED in the receiver which is used as an alignment aid. This LED will begin flashing when the infrared light from the transmitter is “seen” by the receiver. This LED turns off when optimal alignment is attained. An external laser (440L-ALAT) and mounting bracket (440L-AF6109) is offered as an accessory for aligning the GuardShield PAC.
