Be sure to turn OFF the power of the GT2-100 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.
• At startup and during operation, be sure to monitor the function performance of the GT2-100 Series.
• Do not modify the GT2-100 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 GT2-100 Series is used in combination with other instruments, function performance may be degraded, depending on operating conditions and the surrounding environment. Use the GT2-100 Series after fully studying the effect of combined use with other instruments.
• Do not expose the GT2-100 Series and peripheral devices to sudden temperature change. This may cause condensation, damaging the equipment.
Environmental conditions
To use the GT2-100 Series properly and safely, do not install the GT2-100 Series in the following locations. Use of this equipment in an improper environment may cause equipment failure.
Locations outside
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 GT2-100 Series is directly subjected to vibration or impact
Locations where water, oil or chemicals may come into contact with the GT2-100 Series
Locations where static electricity may easily occur
Noise countermeasures
Installation near sources 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 GT2-100 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 force greater than what is listed below to the spindle. Do not apply torque in the rotation direction. 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 GT2-100 Series in high accuracy applications, do not use the GT2-100 Series in the environment in which the surrounding air temperature changes sharply. It will take about 40 minutes on the 12 mm type, and 60 minutes for the 32 mm/50 mm type for the internal temperature distribution 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 14) 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 pply
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 the 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 GT2-P12K(F)/P12(F): OP-87859 (Material: Fluororubber). For GT2-H32/A32: OP-84459 (Material: NBR (attached when shipped)). For GT2-H50/A50 (Material: NBR (attached when shipped)).). Attach the dust boot correctly. The dust boot may deteriorate, depending on the environment it is used in. In this case, replace the dust boot regularly. *
Do not use the dust boot on the GT2-P12KL/P12L/PA12K/PA12/H12KL(F)/H12L(F)/H32L.

Error message

Error display Cause Corrective action
The sensor head cable is disconnected.
• The sensor head cable is broken.
• The sensor head is damaged.
An overcurrent is present in the output line.
Failed to write/read data.
Spindle movement is not detected.
The value fell below (rose above) the timing level during the delay time.
When setting the inter nal timing, detection was completed when the value fell below (rose above) the timing level before the criterion value (P.V. value) is fixed.
Contact between the amplifiers is lost.
• In the case of 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 Series is added.
• When using the reference difference (rEF) calculation function, an error occurred in the main unit.
• When using other than the reference difference (rEF) calculation function, an error occurred in an expansion unit.
The sensor head is connected to the main unit in which the calculation only mode is set.
"com.Loc" is displayed and cannot change the setting.
The calculation mode is used, so the function setting mode cannot be changed.
The criterion value (P.V. value) becomes "------" during the tolerance tuning.
The hold detection is selected or the timing input is not performed, so the criterion value (P.V. value) is not fixed.
The operations of the expansion unit are locked while the simultaneous input is selected and the keylock is activated on the main unit.
After ALL GO is selected in the special output setting, the number of expansion units changed.
*1 If not recovered by this action, there may be a possibility of a failure
or permanent damage. In this case, change the amplifier unit.
*2 Bank switching, reset input, and preset input are available even
during "com.Loc".
• Connect the sensor head to the amplifier.
• Set the valid ID setting correctly.
Change the sensor cable or sensor head.
• Check that the load is within the rating.
• Check that the output line is not contacting other lines and frames.
Cycle power to the equipment and initialize.
• If something is caught in the spindle, causing the spindl e not to move, change the sensor head.
• Check the external timing input. (Press the SET button to reset.)
Change the delay timer time setting. (Press the SET button to reset.)
The value should 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.
After turning OFF the power, check the connection between the amplifiers.
• Reset the calculation mode or perform the initial reset of the main unit.
• After turning OFF the power, check the connections between the amplifiers.
Check each main/expansion unit for the cause of the error.
Remove the sensor head from the main unit or set the mode other than the calculation only mode.
The read/write setting switch of the connected communication
unit DL-RS1A is set to RW. the read/write setting switch to R.
Displayed when this equipment is accessed (operation command/ settings and status writing/keylock) via <DL-CL1>, <DL-DN1> or <DL-EP1>. The buttons are locked, but after approximately 10 seconds, "com.unLoc" is displayed on the amplifier and the
buttons are unlocked. Check the calculation mode settings
again.The function setting mode can be changed only when the calculation mode of the main unit is set to “C0.oFF” or “C5.rEF”.
Perform the timing input and fix the criterion value, and then perform the tolerance tuning.
Perform the timing input.
Deactivate the keylock on the main unit.
• If the number of expansion units has been changed, set the special output setting again.
• If the number of expansion units has not been changed, check if each expansion unit operates correctly, then turn on the power again.
