Checklist
You are fully responsible for performing the risk assessment on your machine application, taking into
account performing maintenance and inspections, which are critical factor for appropriate risk assess-
ment. In addition, it is a responsibility for the responsible personnel to train the machine operators
regarding inspection and maintenance of the machine and the SL-V.

Inspection before operation (Initial inspection)
When the installation of the SL-V is completed, the responsible personnel must verify the operation of the
SL-V in accordance with the checklist shown below. Note that the following inspection items comprise
only a bare minimum inspection. KEYENCE Corporation strongly recommends including the necessary
checking items into this checklist based on the judgment of the responsible personnel since additional
criteria may be necessary depending on both the machine to which the SL-V is installed and the laws,
rules, regulations and standards in the country or region in which the SL-V is used/installed.
(1) Pre-check for installation condition

The machine under SL-V control can be caused to stop running by the OFF-state of OSSD.

The SL-V is installed so that the machine operator cannot go into or approach the hazardous area
without passing through the detection zone.

The interlock reset mechanism is installed so that it cannot be operated if there are any personnel
within the hazardous area.

The device to activate the override is installed so that it cannot be operated if there are any personnel
within the hazardous area.

The SL-V has been installed at a distance greater than or equal to the minimum safety distance
required.

If there are glossy surfaces nearby, move them so that they are beyond the minimum installation dis-
tance according to "Installation Distance From Glossy Surfaces".

The SL-V is installed at a location free from light interference, for example fluorenscent lamps.

The transmitters and receivers are paired correctly.

The beam axis spacing (detection capability) is the same between the transmitter and the receiver
when installing the SL-V.

The muting devices 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.

The devices used to activate the override fulfill the conditions specified in this manual and require-
ments of the laws, rules, regulations and standards in the country or region in which the SL-V and
those devices are used.

When the reduced resolution function is applied, the safety distance is accurately calculated based
on the detection capability, and the SL-V is installed at a distance greater than or equal to the mini-
mum safety distance away from the hazardous zone or hazard.

Risk assessment was performed on your own responsibility based on your machine application, and
then the installation of SL-V was also based on its result.

When the fixed blanking function is applied, a hazardous clearance that is not protected by the SL-V
may be generated between the obstacle and the SL-V. When such a hazardous clearance is gener-
ated, an additional protective device such as a safeguard is installed.
(2) Pre-check for wiring

The SL-V power supply is 24 V DC, fulfill the conditions for the power supply as specified in this user’s
manual.

The transmitter and receiver cables are installed correctly.
