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 (14 to 122°F)

•When 11 to 16 units are connected: -10 to +45°C (14 to 113°F)

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.
		End unit (included with
	Expansion	the expansion unit)

	units

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.

Factory setting

“ ” indicates the factory-set mode. Normally, you should use the CZ-

V1 with the setting indicated by “ ”, and only change the setting if required.

■ Differentiation mode setting (Using DIP switches 1 and 2)

Change the setting according to the detection conditions such as the target color or received light intensity.

	Mode		Switch			Description
	C (Color)			2		Detects color using color components
				1		(R, G, and B).
	C + I			2		Detects color using color components
	(Color and					(R, G, and B) and received light
				1
	intensity)					intensity (received light quantity).
					2
	I	or		1		Detects color using received light
	(Intensity)					intensity (received light quantity).
				2
				1

Sensitivity setting in C or C + I mode Go to page 4.

Sensitivity setting in I mode Go to page 5.

■ 1-point/2-point calibration selection1. (Using DIP switch 3)

Change the calibration method.

	Mode		Switch		Description
	1-P				Detects one specified color. (The
					sensitivity is automatically set to detect
	(1-point			3	only the one color selected during
	calibration)
					calibration.)
	2-P				Differentiates two specified colors.
					(The sensitivity is automatically set to
	(2-point			3
					the optimal value to differentiate the
	calibration)
					two colors selected during calibration.)

■ FINE/HSPD selection (Using DIP switch 4)

Use HSPD when the detection requires a response speed less than 1 ms.

	Mode	Switch			Description
	FINE			4	Differentiates colors with high
	(Fain)				precision.
	HSPD			4	Differentiates colors with a high-speed
	(High-speed)				response of 300 s.

■ N.O./N.C. selection

Change the setting to invert the output mode.

	Mode	Switch			Description
	N.O.				Output is turned on when the target
	(Color match	N.C.		N.O.
	output)				color matches the registered color.
	N.C.				Output is turned on when the target
	(Color
		N.C.		N.O.	color does not match the registered
	mismatch
					color.
	output)

■ Timer OFF/40 ms OFF-delay selection

Change the setting to delay the output timing.

	Mode	Switch				Description
	Timer OFF	DLY.			OFF	Output is turned on without any delay.
	40 ms	DLY.			OFF	Output is delayed for 40 ms.
	OFF-delay

1.The setting of DIP switch 3 is effective only in the C and C + I modes. The setting is unnecessary in I mode.
