SAFETY PRECAUTIONS
This manual describes the instructions, operating procedures and precautions for using the CZ Series.
Before beginning operation, please read this manual carefully to get the most from your CZ Series.
Keep this manual handy for future reference.
WARNING
•The CZ Series is intended for the detection of target objects. Do not use the CZ Series in a safety circuit to protect the human body.
•The CZ Series does not have an explosion-proof structure. Do not use it in a location where any flammable gases, liquid or powder exist.

1.When several units are connected, the acceptable ambient temperature varies depending on the conditions given below. To connect several units, be sure to mount them to a DIN rail (metallic plate). Ensure that the output current is 20 mA max.
•When 3 to 10 units are connected: -10 to +50° C
•When 11 to 16 units are connected: -10 to +45° C
CONNECTING FIBER UNIT AND AMPLIFIER
1.Tilt the quick-release lever.
2.Push the single-core fiber to the transmitter side, and the multiplecore fiber to the receiver side as far as they will go (Approx. 14 mm of the fiber will be inserted.).
*Inserting the fiber in the wrong side will decrease the original detection performance. Be sure to check the markings on the amplifier’s lateral side before inserting the fiber.
3. Raise the quick-release lever.

MOUNTING AMPLIFIER
■Mounting/detaching amplifier to/from DIN rail or mounting bracket
Hook the claw on the rear side of the amplifier onto the DIN rail or the mounting bracket, and then hook the front side claw to the rail or bracket while pressing the amplifier forward. To detach the amplifier, unhook the front claw by lifting the amplifier front side while pressing it
forward. Mounting Detaching
■ Side mounting
Using the side holes of the supplied mounting bracket, secure the amplifier with the screws.
CONNECTING SEVERAL AMPLIFIERS
■ Mounting expansion units
Up to 16 expansion units (FS-T2, FS-M2, FS-V12, PS-T2) can be mounted to the side of the CZ-V1 amplifier.
1. Remove the protective cover on the side of the amplifier.
2. Mount expansion units to the DIN rail |
Remove the |
|
one at a time. |
||
protective cover. |
||
|
3.Slide one expansion unit toward the main unit or another 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 in the expansion unit) from both sides.
|
|
Align the claw. |

Up to 16 expansion units can be connected.
The sticker on the right is included with the expansion unit. Attach the sticker close to the sensor units.
DETACHING EXPANSION UNITS FROM DIN RAIL
1.Detach the end units.
2.Slide the expansion unit that is to be detached. Detach it individually from the DIN rail.
Note 1: When connecting several amplifiers, be sure to use a DIN rail and the end units.
Note 2: Be sure to turn the power off before connecting/disconnecting amplifiers.
Note 3: Do not remove the protective cover on the expansion connector from the outermost unit.
Note 4: Do not detach several units from the DIN rail while they are connected to each other.
Note 5: When several units are connected, confirm that the ambient temperature is appropriate. (See “Specifications” on page 1.)
MOUNTING FIBER UNIT
•Use the supplied special mounting bracket to mount the fiber unit in the desired position according to the location.
•Be sure to limit the tightening torque to 0.3 Nm or less.
