„ Mounting and detaching amplifiers to and from the DIN
rail mounting bracket
Hook the claw on the rear of the amplifier onto the mounting bracket of the DIN rail,
then hook the front claw on the bracket while pressing the amplifier forward. To
detach the amplifier, unhook the front claw by simultaneously lifting and pushing the
amplifier forward.
„ Mounting additional amplifiers
The number of expansion units that can be mounted to the side of main unit
(LV-11A/21A/51M) is as shown below.
1
Remove the protective cover on the
side of the amplifier.
2
Mount expansion units one by one to
the DIN rail.
3
Slide one expansion unit toward the
main unit or other unit. Align the front
claws of the units and push them
together until you hear a click.
4
Secure the units together by pushing
the end units (included with the
expansion unit) from both sides.
* The sticker on the right is included with
the expansion unit. Attach this sticker
near the amplifier.
„ Detaching amplifiers
1
Take off the end unit.
2
Slide the expansion units. Remove them one by one from the DIN
rail.
„ Mounting the reflection type
1
Insert the connector into the amplifier and lock it with the lever.
Pass the cable underneath the lever and close the dust cover.
„ Mounting the transmission type
1
Insert the two connectors into the amplifier unit and lock them
with the lever. Insert the transmitter side connector (with gray
cable) into the light gray lever side, and insert the receiver side
connector (with black cable) into the dark gray lever side. Route
the cable underneath the lever and close the dust cover.
To shorten the sensor head cable
1
Push the upper tab of the connector in the direction of arrow (1)
and open it in the direction of arrow (2) to remove the cables.
2
Cut the cables to the appropriate length, and manipulate the end
of the cables as shown in the figure below.
• Twist the silver shielded wire about five times so it does not ravel, and bend it
90° to the side.
3
Insert the cable with the shield wire bent at 90°C, then bend the
shield wire in the direction of the arrow along the groove. Match
the color of the connector to the color of the shield wire.
4
Close the connector, and lock it by pushing down the top.
5
Using nippers or a similar tool, trim the wires sticking out from
the connectors.
Mounting Amplifiers
Up to 7 LV-22A, LV-52, AP-V42
Up to 14 FS-T2/M2/V12/V22/PS-T2/ES-M2
• When connecting several amplifiers, always use a DIN rail and
end unit.
• Take care to turn the power off before connecting/
disconnecting amplifiers.
• Do not remove the protective cover from the expansion
connector of the outermost unit.
• Do not detach multiple units from the DIN rail while they are
still connected to each other.
• If several units are connected, check that the ambient
temperature is appropriate. “Specifications” (page 8).

Important
When the cable length of the sensor head is changed, be sure to
connect the amplifier to check that it operates correctly.
Do not install the connectors more than two times. If the
installation exceeds twice, purchase OP-27934 separately.
If "brk" appears on the amplifier even when using pliers to crimp
the connector, press the cable (part A) between the metallic
contacts with a thin tool such as a flathead screwdriver to crimp
the cable more firmly.
