•We recommend that you take substantial safety measures to avoid any damage in the event that a problem occurs.

•If the product is modified or used in any way other than those described in the specifications, its functions and performance cannot be guaranteed.

•When this product is used in combination with other devices, the functions and performance may be weaken, depending on the operating conditions, surrounding environment, etc.

•Do not use this product for the purpose of protecting the human body.

•Do not subject each device including peripheral devices to rapid temperature change. Product failure may occur due to condensation.

Safety Precautions on Laser Product

•This product employs a semiconductor laser for its light source.

•Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

•Follow the instructions mentioned in this manual. Other-

WARNING	wise, injury to the human body (eyes and skin) may
	result.
	Precautions on class 1 laser products

Abnormal Conditions

		If the following conditions occur, turn OFF the power
		immediately. Continuing to use this product under abnormal
	WARNING	conditions may cause product failure.
		• When water or foreign matter enters the IG Series
		• When the IG Series is dropped or the case is damaged
		• If smoke or unpleasant odor is present.

Precautions on Use

		• Use with the correct power source and voltage. Otherwise,
	WARNING	fire, electric shock or product failure may result.
		• Do not attempt to open or modify the IG Series. Doing so
		may cause fire or electric shock.

•Before disconnecting the cables, make sure to turn off the main unit and devices connected to the main unit.

CAUTION

Otherwise, the unit may be damaged.

•Do not turn off the power while setting items. Some or all of the set data may be lost.

Installation environment

To use this product normally and safely, do not install this product in the following locations. Product failure may occur.

1-1 Overview of the IG Series

Measurement Principle

This unit receives laser light from the transmitter. The receiver uses a CCD (Charge Coupled Device) as the receiving detector. The CCD is a linear array of light receiving elements. When a target is placed between the transmitter and receiver, a shadow is caused on the receiver. By detecting the light to dark and dark to light transitions, the unit is able to measure those areas accurately.

For details, refer to "4-3 Setting the Measurement Sensitivity" (page 4-44).

1-1 Overview of the IG Series

Using the Expansion Units

The IG Series include main units (IG-1000, IG-1500) and expansion units (IG-1050, IG1550). By connecting the expansion unit to the main unit, the IG Series can be used for various purposes.

Calculation function

Tolerance is judged based on the calculated result (calculated value) of measurement value of two units of IG Series and the analog output can be performed.

"4-4 Calculation Function" (page 4-47)

Adding the measurement value

The diameter or width of a target that cannot be measured with one unit can be measured.

	pushing the main body in the direction of the arrow (1), slant it in the

direction of the arrow (2).

(3)

	(2)	(1)
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).

DIN rail mount type, expansion unit (IG-1050)

Several expansion units can be used in connection with the main unit. Up to 3 expansion units can be connected to one main unit.

•When connecting multiple amplifiers (expansion units), first check to make sure that the power is turned OFF to all of the main and expansion units. Connecting the units

CAUTION

with the power turned ON may cause damage to the units.

•Push the amplifiers (expansion units) as close as possible the main unit. Improper connections may damage the equipment.

Note	• When connecting the expansion units, make sure to initialize the
		connected expansion units and set the output polarity.
	(1) When turning on the amplifier for the first time after connecting the
		sensor head
		"3-1 Operation When the Power is Turned on for the First Time" (page 3-2)
	(2) When performing the initial reset

"3-5 Initial Reset (Initialize)" (page 3-10)

•Expansion units with different setting of output polarity (such as an NPN output expansion unit to a PNP output main unit) cannot be connected together.

•Expansion units of DIN rail mount type cannot be connected to the main unit of panel mount type.

Several expansion units can be used in connection with the main unit. Up to 3 expansion units can be connected to one main unit.

•Turn OFF the power before connecting the expansion cable. Inserting or removing the cable with the power

CAUTION

turned on may cause damage to the units.

•Be sure to completely connect the expansion cable. Improper connections may damage the equipment.

Note	• When connecting the expansion units, make sure to initialize the
		connected expansion units and set the output polarity.

		"3-1 Operation When the Power is Turned on for the First Time" (page 3-2)
	(2) When performing the initial reset

"3-5 Initial Reset (Initialize)" (page 3-10)

•Expansion units with different setting of output polarity (such as an NPN output expansion unit to a PNP output main unit) cannot be connected together.

•Expansion units of panel mount type cannot be connected to the main unit of DIN rail mount type.

1Make holes on the panel to attach according to the number of amplifiers

(connected expansion units).

For the panel cutting size, refer to the "Panel mount type, main unit".

2Install the amplifiers (expansion units) on the panel.

For the amplifier mounting method, refer to the "Panel mount type, main unit".

3Connect the amplifier (main unit) and amplifier (expansion unit) using the expansion cable (50 mm) supplied with the expansion unit.

The expansion unit additionally installed next to the main unit is referred to as expansion unit 1. Subsequent expansion units are referred to as expansion unit 2, expansion unit 3, etc.

Notes for mounting

If the mounting distance between the transmitter and receiver is as follows, the optical axis alignment is not necessary when mounting within the "parallel acceptable range" and "tilt acceptable range".

•IG-010 : 3 to 500 mm

•IG-028 : 50 to 500 mm

If the distance is beyond the above ranges, align the optical axis after mounting.

"3-3 Optical Axis Alignment" (page 3-8)

Note	The minimum object for detection,	linearity and	temperature
	characteristics in the specifications are	values when	mounting the

sensor head within the "parallel acceptable range" and "tilt acceptable range".
