Page 2: General Information
1.1. General description of the SAFEasy safety light curtain The SAFEasy safety light curtains – SF2 Series – are optoelectronic multibeam devices that are used to protect working areas that, in presence of machines, robots and automatic systems in general, can become dangerous for operators that can get in touch, even accidentally, with moving parts. - Page 3 DATASENSOR Sales Technical Service for any necessary information relative to the functioning of the SF2 series light curtains and the safety rules that regulate the correct installation (see section 8 “Checks and periodical...

Page 4: How To Choose The Device
Instruction Manual SF2 Series 1.2. How to choose the device There are at least three different main characteristics that should be considered when choosing a safety light curtain: • The resolution strictly depending on the part of the body to be protected. - Page 5 SF2 Series Instruction Manual • The height of the protected area It is important to distinguish between “Height of the sensitive area” and “Height of the controlled area” (Fig.3). - The height of the sensitive area is the distance between the lower and the upper limits respectively of the first and the last lens.
-
Page 6: Typical Applications
Instruction Manual SF2 Series 1.3. Typical applications The SAFEasy safety light curtains are used in all automation fields where it is necessary to control and protect the access to dangerous zones. In particular they are used to stop the moving mechanical parts of:... -
Page 7: Safety Information
SF2 Series Instruction Manual 1.4. Safety information The following points must be observed for a correct and safe use of the SAFEasy safety device: • The stopping system of the machine must be electrically controlled. • This control system must be able to instantly stop the dangerous movement of the machine during all the phases of the working cycle. -
Page 8: Installation Mode
INSTALLATION MODE 2.1. Precautions to be observed for the choice and installation of the device • Make sure that the protection level assured by the SAFEasy (Type 2) is compatible with the real danger level of the machine to be controlled, according to EN 954-1. -
Page 9: General Information On Device Positioning
SF2 Series Instruction Manual 2.2. General information on device positioning The device should be carefully positioned, in order to reach a very high protection standard. Access to the hazardous area must only be possible by passing through the protecting safety light beams. - Page 10 Instruction Manual SF2 Series In normal operating conditions, machine starting must not be possible while operators are inside the hazardous area. When the installation of the safety light curtain very near to the dangerous area is possible, a second light curtain must be mounted in a horizontal position in order to prevent any lateral access (as shown in Fig.
-
Page 11: Minimum Installation Distance
SF2 Series Instruction Manual 2.2.1. Minimum installation distance The safety device must be placed at a specific safety distance (Fig.5). This distance must ensure that the dangerous zone cannot be reached before the dangerous motion of the machine has been stopped by the ESPE. - Page 12 Instruction Manual SF2 Series Note: The value of K is: 2000 mm/s if the calculated value of S is ≤ 500 mm 1600 mm/s if the calculated value of S is > 500 mm When the dangerous area can be reached through the upper and lower sides of the machine, where devices with >40 mm resolution are...

Page 13: Minimum Distance From Reflecting Surfaces
SF2 Series Instruction Manual 2.2.2. Minimum distance from reflecting surfaces Reflecting surfaces placed near the SAFEasy light curtains (over, under or laterally) may cause passive reflections. These reflections can compromise the recognition of an object inside the controlled area (see Fig. 8). - Page 14 Instruction Manual SF2 Series It is thus important to position the safety light curtain according to the minimum distance from any reflecting surface. The minimum distance depends on: • Operating distance between emitter (TX) and receiver (RX); • Maximum opening angle of the light beam sent by the safety light curtain, in particular: •...

Page 15: Installation Of Several Adjacent Safety Light Curtains
SF2 Series Instruction Manual 2.2.3. Installation of several adjacent safety light curtains When several safety devices must be installed in adjacent areas, it’s necessary to prevent the interferences between the emitter of one device and the receiver of another. Fig.10 gives an example of possible interferences between different devices and two pertinent solutions. -
Page 16: Use Of Deviating Mirrors
Instruction Manual SF2 Series 2.2.4. Use of deviating mirrors The control of any dangerous area, with several but adjacent access sides, is possible using the linear version without integrated Muting sensors and well-positioned deviating mirrors. Fig.11 shows a possible solution to control three different access sides, using two mirrors placed at a 45°... -
Page 17: Mechanical Mounting
SF2 Series Instruction Manual 3. MECHANICAL MOUNTING The emitting (TX) and receiving (RX) units must be installed with the relevant sensitive surfaces facing each other. The connectors must be positioned on the same side and the distance must be included within the operating range of the SF2 light curtain (see section 9 “Technical data”). - Page 18 Instruction Manual SF2 Series L-brackets are available on request (see Fig.13). Rigid fixing brackets can be used where no large mechanical compensation is required during the alignment operation. The rotating supports for the correction of the bar inclination are available on request.
-
Page 19: Electrical Connections
SF2 Series Instruction Manual 4. ELECTRICAL CONNECTIONS Every electrical connection to the emitting and receiving unit is made through a male M12 connector, located in the lower part of the safety light curtain. A M12 5-pole connector is used for the receiver and a M12 4-pole connector for the emitter. -
Page 20: Notes On The Connections
Instruction Manual SF2 Series 4.1. Notes on the connections For the correct functioning of the SAFEasy safety light curtains, the following precautions regarding the electrical connections have to be respected: • Do not place connection cables in contact or near high-voltage cables (e.g. -
Page 21: Test Timing Diagrams
SF2 Series Instruction Manual 4.2. TEST timing diagrams The output functions are self-checked every 0.5 seconds during normal operation. The TEST function also can be activated by simply pressing the external push-button for at least 0.5 seconds as shown in the following timing diagram. - Page 22 Instruction Manual SF2 Series • The OSSD1 and OSSD2 safety contacts cannot be connected in series or in parallel, but can be used separately. • If one of these configurations (Fig.15, 16, 17) is erroneously used, the device enters into the block condition (see cap.7 “Diagnostic functions”).
- Page 23 SF2 Series Instruction Manual The following connection diagram shows how the SF2 light curtain can be connected with force-guided relays (MPCE). User-supplied fuse. For normal operation mode, the TEST wire has to be connected to 24 Vdc by a NC button. If the wire is not connected or connected to 0VDC, the SF2 light curtain enters in break condition.

Page 24: Alignment Procedures
Instruction Manual SF2 Series 5. ALIGNMENT PROCEDURES The alignment between the emitting and the receiving units is necessary to obtain the correct functioning of the light curtain. The alignment is perfect if the optic axes of the first and the last emitting unit’s beams coincide with the optic axes of the corresponding... - Page 25 SF2 Series Instruction Manual Verify that one of the following conditions is present on the RX unit: SAFE CONDITION 1. The green LED (SAFE) is ON and the red LED (BREAK) is OFF. Both yellow LEDs (High ALIGN and Low ALIGN) are OFF.
