Section 1: Operation
The Safety Light Curtain (SLC) is made up of one active side with transmitter and receiver optical elements
called the transceiver and one completely passive side, with a mirror system.
The operator has a multifunction pushbutton, which is used for the following:
• TEST: If pressed during normal operation, it checks if all of the system, comprising of the SLC and the
machine is working. Pressing the TEST button (opening the contact) basically simulates the interruption
of one or more safety beams and it is possible to check that the machinery stops in the correct time and
configuration.
• RESTART: If pressed after an intervention by the SLC, (manual reset condition) the system will be
reset.
• ALIGNMENT: If the button is pressed when there is no power supply to the SLC and then power is
restored, whilst the button is being pressed, it enters alignment mode, i.e. it provides an indication of the
alignment position of the unit by means of two yellow LEDs.
• OVERRIDE: (only present if the muting function is operational) if the button is pressed within 5 seconds
of switching on and it is kept pressed for at least 5 seconds, the SLC will close the safety outputs if the
beams are interrupted. This condition stops as soon as the button is released or automatically after
120 seconds.
1. Automatic reset: After the SLC has detected an object, it returns to normal operation as soon as the ob-
ject is removed.
2. Manual reset: Normal operating mode is only restored after the object has been removed and the reset
button has been pressed.
To enable the muting function, the LMS muting indicator must be connected when the SLC is not connec-
ted to the power supply, as shown in section 6, and then the SLC's power supply must be restored. To
disable the muting function, the LMS muting indicator must be disconnected when the SLC is not connec-
ted to the power supply, and then the SLC's power supply restored.
Please remember that by enabling/disabling the muting function the override function is automati-
cally enabled/disabled.
The outputs are PNP type.
Should the load to be controlled have alternating current or require more than 250 mA consumption, it is ne-
cessary to use an external safety relay module.

8 2-1 Calculation of the minimum distance for installation
Section 2: Precautions and criteria for installation
The area where the SLC is to be installed must be compatible with the SLC 's technical specifications. The
temperature of the environment, interference caused by electromagnetic disturbance and sources of light
and such like, should be assessed a competent person. Please contact the manufacturer for any information
not contained in this manual.
2-1 Calculation of the minimum distance for installation
The safety distance 'S' must guarantee that the operator cannot reach the danger zone before the machinery
with the moving parts has stopped. The formula to calculate the safety distance for multi-beam SLCs is as
follows:
S = (K * T) + C
S = safety distance.
T = T1 + T2
where T1 = machinery's response time in seconds.
T2 = SLC's response time in seconds.
K = 1600 mm/s (approach speed of the body to the danger zone).
C = 850 mm
S = safety distance.
H1 = the bottom optical beam must not have a height above 400 mm.
H2 = the top optical beam must not be below 900 mm.
! Do not use F3S-TGR-SBx-KxC series in horizontal position.

2-2 Reflecting surfaces 9
2-2 Reflecting surfaces
!Be sure to install the SLC to minimize the effect of reflection from nearby surfaces. Serious injuries
can result if these effects are not taken into consideration.
Should there be any reflecting surfaces, the distance must be sufficient to safeguard against passive
reflections.
The distance can be calculated following the table below:
where 'D' and 'L' are expressed in m
Reflecting surface
Model L distance between SLCs Minimum permitted installation distance D
F3S-TGR-SB2-KxC 0.5 to 3 m 0.26 m
Over 3 m L/2 x tan5° = L/2 x 0.088 (m)
F3S-TGR-SB4-KxC 0.5 to 3 m 0.13 m
Over 3 m L/2 x tan5° = L/2 x 0.044 (m)

10 Section 2: Precautions and criteria for installation
If several SLCs are used, care must be taken that each SLC does not interfere with the ones nearby;
please install as follows:
)Install the SLC so that they emit in the opposite directions (Staggered)
)All these installation will prevent mutual interference between SLC.
