●

Noise countermeasures

Installation near a source of electrical noise such as a power
source or 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.

●

Handling of the sensor head

•

The GT2-500 Series and peripheral devices are precision
machines. Do not drop, or cause any other impact to these
devices. Doing so may cause damage or malfunction.

•

Do not apply weight greater than what is listed below to the spindle.
Do not apply rotational torque. Otherwise the spindle may break.

•

The GT2-P12KL(F)/P12L(F)/PA12K/PA12 spindle can rotate a
maximum of about 4.5°. When using an offset contact (OP-

77683) or similar, if pressure in the rotational direction is
applied to the contact, the measurement position may change.

•

Although the GT2-PA12K/PA12/H12K/H12KF/H12/H12F/
H32/H50/A12K/A12/A32/A50 has a protection rating of
IP67, avoid using it immersed in water or in places where
liquid such as oil may come into contact with it.

•

Although the GT2-P12K(F)/P12(F) has a protection rating of
IP67G/NEMA Type 13, some types of oil may damage the device.

•

If dust, metal powder, or similar becomes attached to the
sliding part of the sensor head, mechanical responses may
become slow. If this happens, replace the dust seal with a
replacement dust seal (OP-87932). Refer to the instruction
manual included with the replacement dust seal (OP-

87932) for instructions on how to replace the dust seal

■

Other precautions

●

Effects of surrounding air temperature

To use the GT2-500 Series with high accuracy, do not use the GT2-500 Series
in an environment in which the surrounding air temperature changes sharply.
It will take about 40 minutes for the 12 mm type, and 60 minutes for the 32 mm/
50 mm type for the internal temperature to stabilize when the surrounding air
temperature has changed by 10°C.

●

Warming up

The circuit is not stable immediately after the power turns ON, which
sometimes causes the indicated value to gradually fluctuate. Wait for about
5 minutes when using the 12 mm type and about 10 minutes when using
the 32/50 mm type after the power turns on before starting operation.

●

GT2-PA12K/PA12 (See illustration 1 for the pneumatic circuit)

•

This model uses a single-acting cylinder. The internal spring will
return the sensor head to its home position.

•

The air supply hole cannot be removed.

•

Use an air filter, mist separator, etc. to provide clean dry air. Empty the
drainage from the filter regularly, before it exceeds the specified line.

•

Before connecting the air tube to the air supply hole, be sure to blow plenty of
air through the pipes (flushing) to remove any foreign matter.

•

Make sure that the air pressure of the supplied air is constant and in the range
of 0.24 to 0.26 MPa. Use a precision regulator to control the air pressure. If
the air pressure is below 0.24 MPa, the spindle may not extend fully.

•

When supplying air (with the spindle extended), up to 3L/min of air will be
emitted from the tip of the dust seal.

•

The measuring ability of the device changes according to the air pressure
of the air supply. Refer to "Specifications" (page 9) for details.

●

GT2-A12K(L)/A12(L)/A32/A50 (See illustration 1 for the pneumatic circuit)

•

This model uses a single-acting cylinder. The internal spring will
return the sensor head to its home position when air pressure is
removed. DO NOT supply air to the exhaust valve.

•

The air cylinder cannot be removed.

•

Use the regulator to supply the stable air pressure to the sensor head.

•

Use the air filter and mist separators to supply dry air. Empty the drainage
from the filter regularly, before it exceeds the specified line.

•

Make sure that the air pressure of the air supply is constant and in
the range of 0.25 MPa to 0.5 MPa.

•

The coupling socket and the exhaust valve that are supplied with the
air cylinder are dedicated for this product. They cannot be removed.

●

Power su pp ly

•

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.

●

About dust boot

When the dust boot of the sensor head is damaged, use an optional dust
boot sold separately (For GT2-P12K(F)/P12(F)/H12K(F)/H12(F)/A12K/
A12: OP-84332 (Material: NBR (attached when shipped)). For GT2­P12K(F)/P12(F): OP-87859 (Material: Fluororubber). For GT2-H32/A32:

For GT2-A12K/A12/A32/A50 when an IP67 enclosure
rating is required

To maintain an IP67 enclosure rating for GT2-A12K/A12/A32/A50,
the following must be satisfied:

•

Firmly connect tubing with 2.5 mm inner diameter to the exhaust
port until it bottoms out.
Ensure that the tube end is free of dirt or water.

•

Tighten the screw of the exhaust valve with a torque of 0.5 to 0.6 N・m.
If the screw is loose, the IP67 rating cannot be guaranteed.

Reference

By loosening the screw of the exhaust valve, you can
change the exhaust port angle.

Contact

This section describes how to replace the contact, and how to mount
the lift lever.

• Detach the sensor head from the device or fixture
(metal plating, etc.) before replacing the contact.

• When applying pliers to the contact, be sure not to
rotate the main part and cover the contact with a cloth.

• Never apply tightening torque over 0.2 N
attaching a contact.

• Fix the roller contact (OP-77680) or the offset contact
(OP-77683) with the fixing nut in the same direction as in
actual use.

• Applying an adhesive, a thread locking agent, is
recommended to prevent the nut from getting loose.

• Position the roller contact carefully in the proper
direction. Care must be taken not to apply misdirected
force to the shaft.

■

How to replace the contact

・

m when

While securing the spindle with the accessory key wrench, detach
the contact with pliers. Then attach a new contact.

How to replace the dust seal

Refer to the instruction manual included with the replacement dust seal
(OP-87932).

■

How to mount the lift lever

Mount the lift lever (OP-84397) between the spindle and the contact.
Secure the spindle with the lift lever and attach/detach the contact.

●

Adjustment of Spindle Movement Speed

To adjust the spindle movement speed, install a speed controller
between the cylinder and the air supply. Using OP-87970 is
recommended.

• To further decrease spindle movement speed, use
a coil-shaped tube (OP-87986) or similar to
increase the distance between the air supply hole
and the speed controller.

• The speed controller will not operate if installed in
the reverse direction.

Cautions

• If, for example, channel C on the main unit is enabled during use, the
ID for channel C becomes 03, and each subsequent ID has 1 added
to it.
Therefore it may be necessary to change the PLC program.

• When a channel is enabled but no sensor head is connected, it is
recognized as a head error.

The example below shows 1 main unit (GT2-500) connected to 2
expansion units (GT2-550) (the expansion unit connected to the main
unit is expansion unit 1, and the expansion unit connected to expansion
unit 1 is expansion unit 2), with 11 sensor heads being used in total.

error

• The sensor head is
disconnected.

• The sensor head cable is
broken.

• The sensor head is
damaged.

• Failed to write data.

• The spindle is jammed.
(When using the jam
detection function)

• The value fell below (rose
above) the timing level
during the set delay time.

• The value fell below (rose
above) the timing level
before the detection status
was stable and the
criterion level (P.V. value)
was fixed when using
static hold internal timing.

• The value rose above (fell
below) the timing level,
then fell below (rose
above) the timing level
before the criterion level
(P.V. value) was fixed when
using delay timer internal
timing.

• When using the calculation
function, the number of the
expansion unit when the
power is turned ON differs
from the number of the
expansion unit in the
memory of the main unit
when the calculation is set.

• When using the calculation
function, a model other
than the GT2-500/70
Series is added.

• When using the reference
difference calculation
function, an error occurred
in the main unit.
When using other than the
reference difference

alculation function, an

c
error occurred in an
expansion unit.

• The sensor head is
connected to the main unit
in which the calculation
only mode is set.

• Connect the sensor
head.

• Replace the sensor
head cable.

• Replace the sensor
head.

• Turn the equipment off
and on, and perform
initial reset. (If this
does not solve the
problem, the
equipment may be
damaged, or may have
reached the end of its
service life. Replace
the amplifier unit.)

• If the spindle is
jammed and does not
move, replace the
sensor head.
Use a Communication
Unit to check that the
timing input is
appropriate.

• Make sure that the
value does not fall
below (rise above) the
timing level before the
criterion value is fixed.
Alternatively, lengthen
the static hold delay
stabilizing amplitude
so that the criterion
value can be easily
fixed.

• Reset the calculation
mode or perform initial
reset of the main unit.
Perform initial reset via
the Communication
Unit. See the DL
Series manuals for the
method.

• Check each main/
expansion unit for the
cause of the error.

• Remove the sensor
head from the main
unit or set a mode
other than the
calculation only mode.
