SL-V-M-NO0-E

Installation
• The SL-V must be installed only after ensuring the minimum safety distance between the
SL-V and the hazardous zone or hazard as established by the applicable regulations in the
country or region in which the SL-V is used. (e.g.EN ISO13855(ISO 13855)in EU countries)
• Choose locations for the installation of the SL-V transmitters and receivers so that they are
not subject to the effects of light reflected from glossy surfaces in the area.
• Correct operation and detection is not possible if the receiver has a different number of
beam axes from that of the transmitter. You must verify that the number of beam axes is the
same between the transmitter and the receiver when installing the SL-V.
• Correct operation and detection is not possible if the receiver has a different beam axis
spacing (detection capability) from that of the transmitter. You must verify that the beam axis
spacing (detection capability) is the same between the transmitter and the receiver when
installing the SL-V.
• The SL-V must be installed so that the machine operator is able to go into or approach the
hazardous zone or hazards only by passing through the detection zone of the SL-V. Strictly
avoid installation that allows the machine operator or a part of the machine operator's body
to go into or approach the hazardous zone or hazards without passing through the detec-
tion zone of the SL-V or to remain in a position between the detection zone of the SL-V and
the hazardous zone or hazard. In case where you install the SL-V units in series (series
connection), you always must check the installation carefully whether you follow this warn-
ing, especially after installation and maintenance.
Even if you forget to install the SL-V unit to be connected in series, or if the series connec-
tion cable is disconnected, the SL-V does not detect such a missing or disconnection. (It
means the SL-V starts the normal operation.) This causes a dangerous situation because
there is no protection at the area to be protected.
• You must always perform the pre-check tests after installing the SL-V in accordance with
the pre-check test procedures, such as items specified in this user’s manual, in order to ver-
ify that the test pieces can be detected in all of the detection zones.
• Interlock reset mechanisms (such as switches) must be installed so that the whole hazard-
ous zone can be checked by the responsible personnel. Interlock reset mechanisms should
not be accessible from within the hazardous zone.
• Muting is a function to allow a temporary automatic suspension of the SL-V safety functions
while the SL-V is receiving a signal from muting devices (such as sensors or switches).
Therefore, additional safety measures are required for the machine on which the SL-V is
installed in order to ensure safety while the muting is activated.
• Muting devices, the installation of those devices and the procedure to activate the muting
function must fulfill the conditions specified in this user’s manual and the requirements of
the laws, rules, regulations and standards in the country or region in which the SL-V and
those devices are used. Failure to follow this warning may result in significant harm to the
machine operators, including serious injury or death.
• When you install muting devices (such as sensors or switches) for muting, the following
conditions must be fulfilled.
(1) Muting devices must be installed so that the muting cannot be activated if the
hazardous zone of the machine is in an unsafe condition or cycle.
(2) Muting devices must be installed so that the muting cannot be activated even if the
personnel is accidentally approaching the detection zone of the SL-V.
• The muting device must be installed such that only responsible personnel have access to that
device to change its installation or orientation. Special tools must be required to ensure that only
responsible personnel are capable of installation, orientation or change of muting device.
• Only the responsible personnel may be allowed to install or wire the devices to activate the
muting function.
