Safety Precautions

Symbols

This instruction manual describes the operation and function of the EX-V. Read this
manual carefully to ensure safe use and maximum performance from your EX-V.

The following symbols alert you to important messages. Be sure to read these
messages carefully.

WARNING

Failure to follow instructions may lead to injury. (electric
shock, burn, etc.)

General precautions

CAUTION

Note:

• At startup and during operation, be sure to monitor the functions and perfor­mance of the EX-V.

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

• Do not open or modify the EX-V or use it in any way other than described in the
specifications.

• When the EX-V is used in combination with other instruments, functions and
performance may be degraded, depending on operating conditions and the
surrounding environment.

• Do not use the EX-V for the purpose of protecting the human body.

Failure to follow instructions may lead to product damage.

Provides additional information on proper operation.

i

Warning and cautions specific to the EX-V Series

Operating environment

For optimum performance of the EX-V, always maintain a proper operating envi­ronment.

CAUTION

Connecting the EX-V to analog input equipment

To prevent malfunction, do not install the EX-V in the following places:

• Places directly exposed to sunlight.

• Places where the ambient temperature drops below 0

• Places where the relative humidity drops below 35% or exceeds 85%.

• Places where temperature fluctuations may cause condensation.

• Places where the EX-V may be exposed to corrosive or flammable gas.

• Places exposed to airborne dust or corrosive substances such as salt or
metal particles.

• Places where the EX-V may be subjected to vibration or impact.

• Places where water, oil or chemicals may splash the EX-V .

• Places where the EX-V may be affected by noise interference.

Take the following countermeasures to prevent the EX-V from malfunctioning due
to noise interference.

Note 1: Use a 1-core shielded cable for the output line. When using an analog
voltage signal, do not use a cable longer than 10 m. If the cable needs to be
longer than 10 m, convert the voltage signal into a current signal.

Note 2: Keep the wiring and connection cables separate.
Note 3: Isolate the wiring and connection cables from high-voltage or power lines;

otherwise noise may cause the EX-V to malfunction.

Mounting

Insert the controller from the front of the panel and fix it using the panel mounting
frame.

Dismounting

1. Insert the controller.

1.5.2 Mounting the sensor head

Mounting

• Tighten the EX-305V set screw and EX-110V nut away from the tip of the
sensor head as shown in the figure.

If the position is changed, the output characteristics may change even when the
nut or screw is positioned in the range shown in the figure.

Chapter 1 Preparation

When mounting two or more sensor heads of the same model in parallel

• The sensor may not output the correct voltage due to mutual interference. Make
sure that the distance between sensor heads adjacent to each other is larger
than the values shown in the table below. (This allows the display resolution
specification to be satisfied when the number of measurements to average is

1

"64".)

• When two sensor heads are mounted in parallel, mutual interference can be
prevented by alternately oscillating the sensor heads using the synchronous
input terminal (

Tightening torque

To tighten the EX-305V set screw, apply a torque of 0.2 N•m or less.
To tighten the nut of the other sensor heads, apply a torque shown in the table
below or less.

CAUTION

• If the applied tightening torque exceeds the specified one, the sensor
head may be deformed or malfunction.

• If the sensor cable is installed in the same conduit as high voltage lines or
power lines, the sensor may malfunction. Be sure to keep the wiring
separate.

Note: Do not change the sensor cable length (3 m). If the cable is extended or cut,

the characteristics will change.

1.6 Adjustment

1.6.1 Connection

Chapter 1 Preparation

Though the EX-V series has been factory-adjusted, follow the procedure described
below to adjust the sensor using your actual target in order to satisfy the
specifications. When the sensor head has been replaced, be sure to make this
adjustment.

1. Connect the core and shielding wires of the sensor head to sensor head
connection terminals 11 and 12 of the controller.

1

2. After making the connection,
connect the power supply cable to
power supply terminals 1 and 2.

The POWER indicator on the
controller illuminates, and the
sensor enters the operation state.

24V DC

Note: Let the sensor warm up for 30 minutes or more after supplying power to it,
and then start the adjustment.

1.6.2 Adjusting the output characteristics

1. Press the key for at least 2 seconds.

The sensor displays "0" and enters the adjustment mode.

2.1 Measurement Modes

The EX-V series provides the following four measurement modes: "Bottom-dead­center mode", "Eccentricity/vibration mode", "Thickness/gap mode" (which are
basic modes for quick operation), and "Manual mode" (which allows users to
perform setting as desired). This section explains the major functions of each
mode.

2.1.1 Bottom-dead-center mode

2

This mode is used to measure the displacement of the origin position of a machine
with stroke movements such as a press. When the displacement of the bottom
dead center or origin position is out of the preset tolerance range, the sensor
outputs an Alarm signal.

Major applications

• Detecting the bottom dead center position of a press

• Detecting the bottom dead center position of a press-fit machine

• Detecting the bottom dead center position of a welding machine

• Pressure control for a injection molding machine

• Measuring the depth of the recess on a piston head

2.1.2 Eccentricity/vibration mode

This mode is used to measure the roller eccentricity or abnormal machine vibration.
When the amplitude of the runout or vibration is larger than the preset tolerance
limit value, the sensor outputs an Alarm signal.

Major applications

• Measuring roller eccentricity

• Measuring surface plate runout

• Detecting runout due to improper chucking

• Measuring drill bit eccentricity

2.1.3 Thickness/gap mode

This mode is used to measure target thickness or gap with a direct reading value.
When the thickness or gap is larger or smaller than the preset upper or lower value
for the tolerance limit, the sensor outputs an Alarm signal.

In addition to the modes above, the manual mode is available. The manual mode
provides the following six data processing modes to allow adaptable measurement.

method.

2.2.1 Setting the bottom-dead-center mode

comparator output.

2. Adjust the distance between the sensor head and target.

Move the press an inch at a time and lower the stripper (or upper die) to the
bottom dead center position. (Refer to the figure below.)

3.2.3 Monitor (analog voltage) output setting function [F]

This function is used to change the ratio of the analog voltage output value relative
to the displayed value, provided that the output voltage is between -5 and +5 V. By
performing scaling, you can change the output voltage value to the desired level. In
addition, you can select either of the following two output methods: one outputs
analog voltage according to the displayed value and the other outputs the input
value from the sensor head.

Reference: The initial state outputs the voltage equal to the displayed value.

You can display the signals input from the sensor head by eliminating the
signals higher than a specified frequency. This function is effective to ignore
abrupt fluctuations and to obtain a smooth curve display.
