channel selection switch. (It does with Output1 in area detection mode.)
Input/Output Circuit Schematic
Output circuit
LV-11SA/12SA (NPN output type)
LV-11SAP/12SAP (PNP output type)
The power of the expansion unit LV-12SA (P) is supplied by the Extension
connector on the side of the main unit LV-11SA (P). The power wires (brown
and blue) of the main unit and those of the expansion unit are unified inside
by the connector.
■ Input circuit
LV-11SA/12SA (NPN output type)
LV-11SAP/12SAP (PNP output type)
Mounting the Amplifier Unit
■ Mounting on a DIN rail
1) Align the claw at the bottom of the main body with the
DIN rail. While pushing the main body in the direction
of the arrow 1, slant it in the direction of the arrow 2.
2) To dismount the sensor, raise the main body
in the direction of the arrow 3 while pushing
the main body in the direction of the arrow 1.
■ Installation using the mounting bracket (accessory)
(LV-11SA/11SAP only)
Mount the amplifier unit using the supplied
mounting bracket as shown in the figure.
■ Connecting several amplifier units
Up to 16 expansion units LV-12SA can be installed to the main unit LV-11SA.
1
Remove the protection cover on the side of the
main unit.
2
Install the amplifier one by one on the DIN rail.
3
Engage the two claws of the expansion
unit with the recesses on the main unit
side until you hear a click sound.
4
Install the end units on both ends of
the amplifier unit.
Fasten the screws on the top of the
end units (at two positions on both
end units) with the Philips screw-
driver.
* The stickers on the right are provided. Attach the
sticker on the place near the amplifier unit.
■ Removing the amplifier unit
1
Remove the end units.
2
Slide the expansion unit and remove it one by one.

Important
• When installing additional expansion unit, be sure to use the DIN rail and the end units.
• Turn off the power when installing or removing the unit.
• Do not remove the protective cover of the extension connector on the amplifier
expansion unit that is added at the end.
• Do not remove the amplifier unit with all added units attached, from the DIN rail.
• Verify the operation ambient temperature after additional installation.
