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 object 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 connected 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 connected 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 automatically enabled/disabled.
The outputs are PNP type.
Should the load to be controlled have alternating current or require more
than 500mA consumption, it is necessary to use an external safety relay
module.

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.
Number of beams Heights above the reference plane, e.g. ground in mm

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
L distance between SLCs Minimum permitted installation
distance D
0.5 to 3 m 0.13m
Over 3 m L/2 x tan5° = L/2 x 0.088 (m)
