GuardShield Safe 4 Operation Manual 2. Introduction Finger (14 mm) and hand protection (30 mm) Large range with a compact profile type: 14 mm resolution: 0 m to 6 m 30 mm resolution: 0 m to 6 m GuardShield Safe 4 safety light curtains are active optoelectronic protective equipment AOPE type 4 with object detection capability of 14 mm or 30 mm.
GuardShield Safe 4 Operation Manual 3.2. Applications restrictions GuardShield Safe 4 is not designed and approved for any application in explosive EX or radioactive areas. 3.3. Application conditions The safe application of the light curtain system GuardShield Safe 4 needs certain precautions: 1. 2. 3. The control unit of the machine or system must be able to be electrically stopped and the stop time must be known.
GuardShield Safe 4 Operation Manual As accessories two types of mirrors are available, with different mounting plates and sizes. Detailed information is available from ROCKWELL AUTOMATION. 4. Principles of operation The transmitter sends coded infrared light pulses to the receiver, which evaluates them. If an object e.g. a finger (14 mm) or a hand (30 mm) penetrates the protective field, the fully redundant solid state Output Signal Switching Devices OSSD of the receiver switch off to stop the machine.
GuardShield Safe 4 Operation Manual 5.1.1. IEC Safety distance to danger point According to the standards, the GuardShield Safe 4 light curtain and the point of danger must be separated by a defined safety distance. This minimum distance safeguards that the danger point may only be reached after the hazardous motion has stopped.
GuardShield Safe 4 Operation Manual This distance, referred to as the safety distance, must be properly calculated prior to determining the safety light curtain protective height and mounting the light curtains on the machine. Failure to properly calculate this safety distance may result in operator injury.
GuardShield Safe 4 5.1.5. Operation Manual Distance to reflective surfaces Reflective surfaces may cause reflections within the transmitter and receiver aperture angle, i.e. an interruption of the protective field would not be recognized (Figure 7). The safety light curtain has been thoroughly tested against light interferences according to the stringent requirements of IEC 61496.

GuardShield Safe 4 5.2.3. Operation Manual Adjustment Procedure without ILAS 1. Mount the transmitter and the receiver with the adjustable mounting brackets. Make sure that the longitudinal axis of both are oriented parallel. A spirit level might help to find the correct position. 2. Take care that the receiver and transmitter are oriented in the same direction. This means, the controllers of the transmitter and receiver have to be at the same end of the protective field.

GuardShield Safe 4 Operation Manual Important information: Safety devices for connection of GuardShield Safe 4 must be built with PNP logic. The outputs will be periodically controlled for short-circuit and cross-fault detection. 1. The output voltage at the solid-state outputs is dependant on the power supply and the output load (see chapter 11 Technical Data). 2. 3. 4. 5.3.6.
