Page 2: Introduction
Type 2 electrosensitive devices according to EN 954-1. The SLC 210 / SLG 210 barrier, which consists of an Emitter and a Receiver, is a type 2 optoelectronic safety device according to standards IEC 61496-1 and IEC 61496-2. -
Page 3: Operation
If the latter is placed horizontally, this value refers to the depth of the protected area. The working range is the maximum operative distance that can exist between the Emitter and the Receiver. SLC 210 / SLG 210 is available with the following resolutions: – 20 mm (protected height from 160 mm to 1800 mm) PROTECTION OF FINGERS –... -
Page 4: Installation
SLC 210 / SLG 210 INSTALLATION Before installing the SLC 210 / SLG 210 safety system, make sure that: The safety system is only used as a stopping device and not as a machine control device. The machine control can be actuated electrically. -
Page 5: Positioning
SLC 210 / SLG 210 The recommended Cf factors are shown in the table below: ENVIRONMENTAL CONDITION CORRECTION FACTOR Cf 0.25 Steam 0.50 Dust 0.50 Dense fumes 0.25 If the device is installed in places that are subject to sudden changes in temperature, the appropriate precautions must be taken in order to prevent the formation of condensation on the lenses, which could have an adverse effect on monitoring. -
Page 6: Safety Distance Calculation
SLC 210 / SLG 210 SAFETY DISTANCE CALCULATION The barrier must be installed at a distance that is greater than or equal to the minimum safety distance S, so that a dangerous point can only be reached after all hazardous machine movements have stopped (Figure 3). -

Page 12: Multiple Systems
SLC 210 / SLG 210 MULTIPLE SYSTEMS When more than one SLC 210 / SLG 210 system is used, precautions must be taken to avoid optical interference between them: install units so that the beam emitted by the Emitter of one system can only be received by the relative Receiver. - Page 13 SLC 210 / SLG 210 Figure 12 illustrates the values for the minimum distance d that must be maintained when the distance l between the Emitter and Receiver is changed. Figure 12 After installing the system, check whether any reflecting surfaces intercept the beams, first in...

SLC 210 / SLG 210 USE OF DEFLECTION MIRRORS In order to protect or control areas that can be accessed from more than one side, to the Emitter and Receiver in addition, one or more deflection mirrors can be installed. -
Page 15: Mechanical Assembly And Optic Alignment
SLC 210 / SLG 210 MECHANICAL ASSEMBLY AND OPTIC ALIGNMENT The Emitter and the Receiver must be assembled opposite each other. Use the fastening brackets and inserts supplied with the system to place the Emitter and the Receiver so that these are aligned and parallel to each other and with the connectors facing the same way. -
