Safety Precautions

■

General cautions

• At startup and during operation, be sure to monitor the function

performance of the GT-70A Series.

• Do not modify the GT-70A Series or use it in any way other than

described in the specifications. The function performance of

products used or modified in this way cannot be guaranteed.

• When the GT-70A Series is used in combination with other

instruments, function performance may be degraded, depending on

operating conditions and the surrounding environment. Use the GT-

70A Series after fully studying the effect of combined use with other

instruments.

• Do not use the GT-70A Series for the purpose of protecting the

human body.

• Do not expose the GT-70A Series and peripheral devices to sudden

temperature change. This may cause condensation, damaging the

equipment.

●

Environmental conditions

To use the GT-70A Series properly and safely, do not install the GT-70A

Series in the following locations. Use of this equipment in an improper

environment may cause equipment failure.

•

Locations with high humidity, a large amount of dust, or poor ventilation

•

Locations where the temperature rises excessively due to direct

sunlight, etc.

•

Locations near corrosive or flammable gas

•

Locations where the GT-70A Series is directly subjected to

vibration or impact

•

Locations where water, oil or chemicals may come into contact with

the GT-70A Series

•

Locations where static electricity may easily occur

●

Noise countermeasures

Installation near the noise source such as a power source and a

power cable may cause malfunction or failure of the equipment.

Adopt appropriate countermeasures against noise by using a noise

filter or wiring cables in separate ducts, attaching insulation to the

amplifier or the sensor head, etc.

●

Effects of ambient temperature

Change in ambient temperature may cause detection errors. Keep

ambient temperature at a constant level.

It will take about 40 minutes for the internal temperature distribution

of the equipment to completely adjust when the ambient

temperature has changed by 10°C.

●

Warming up

Wait about 30 minutes after the power is turned ON before beginning

operation. Immediately after the power is turned ON, the circuit

becomes unstable, possibly causing the indicated value to slightly

fluctuate.

●

Handling of the sensor head

•

The GT-70A Series and peripheral devices are precision machines.

Do not drop, or cause any other impact to these devices.

•

Do not apply weight greater than what is listed below to the spindle part.

Do not apply torque in the rotation direction. Otherwise the spindle may

break.

•

Although the sensor head has a waterproof structure, avoid using in

water or in the place where liquid such as water and oil may come into

contact with the sensor head.

●

Extending cable between amplifier and sensor head

Do not cut or extend the cable between the amplifier and the sensor

head. This may change the characteristics, causing the

specifications not to be satisfied.

●

Power supply

•

Noise superimposed on the power supply may cause malfunction.

Be sure to use the DC stabilized power supply provided with an

insulation transformer.

•

In the case of a commercially available switching regulator, be

sure to ground the frame ground terminal or the ground terminal.

●

Effects of vibration

Vibrating the detection target may cause fluctuation in the indicated

value. In this case, extend the response time. This ensures more

accurate detection values.

●

Effects of magnetic fields

Contact by an external magnetic field to the sensor head will

influence the output. Avoid installing the GT-70A Series near motors

or other equipment and devices that generate strong magnetic

fields.

●

About dust protective boot

An optional dust protective boot is available (GT-H10: OP-78041, GT-

H22: OP-78042) for when the included dust protective boot has been

cracked or damaged. Please note that we cannot guarantee the

protection rating IP67 when the optional part is used. If you need a

guarantee for the protection rating IP67, replace the sensor head

itself.

WARNING

If the following conditions are encountered,

immediately turn OFF the power. Continuing to use

the GT-70A Series under these abnormal conditions

may cause equipment failure.

• When water or foreign matter enters the controller

• When the GT-70A Series is dropped or the housing

is damaged

• When the GT-70A Series produces smoke or an

abnormal smell

WARNING

• Do not use the GT-70A Series with a voltage other

than specified voltage, as this may cause fire,

electric shock or equipment failure.

• Do not disassemble or modify the GT-70A Series.

This may cause fire or electric shock.

CAUTION

•

Be sure to turn OFF the power of the GT-70A Series and

any connected devices before connecting or

disconnecting the cables. Otherwise, there may be a risk

of damage.

•

Do not turn OFF the power while setting parameters.

Otherwise, the settings may be partially or completely lost.
