the danger of a burn injury. Do not touch the |
|
metal housing while the product is in operation. |
||
|
2.The screw part of the main unit is sharp, take care to avoid injury.
1.Do not drop or hit the device, and avoid any other large shock to the device.
2.Do not use a sharply pointed object to press the setting keys.

Precautions for wiring
1.Do not modify or disassemble unnecessarily. It may cause electric shock or improper operation.
2.Do not work on the wiring with bare hands. Even if the power is OFF, electric charge may remain and cause electric shock.
3.Do not work on the pipe work or wiring with
CAUTION |
|
wet hands. It may cause electric shock. |
|
4. |
When wiring, confirm the pin position. |
5. |
Use the GP-M Series within the rated range. |
|
|
|
The GP-M Series is a sensor that uses a DC |
|
|
(direct current) power source. Do not apply |
|
|
alternating current or other power supplies. Do |
|
|
not use a load that exceeds the allowable limit. |
1.Use an insulated stabilizing supply for the power supply.
2.Do not pull strongly on the cable.
3.Ensure that the cable tip is not submersed in
NOTICE |
water during wiring work. |
4.Isolate the cable from power supply lines or power lines.
5.Isolate the cable as far as possible from any source of noise.
Other precautions
1.The power ON reset time for the GP-M Series is 2 seconds after power is turned on. Do not use outputs from the sensor during this period.
2.Initial drift may occur after supplying power to
NOTICE |
the GP-M Series. To detect a minute difference |
|
in the pressure, let the GP-M Series warm up |
|
for approximately 15 to 30 minutes. |
3.Do not bring a strong magnet or magnetic field close to the main body of the GP-M Series.
5
4.Do not remove the seal of the air hole of the GP-M001/M010/M025. It will no longer be waterproof.
5.When condensation occurs, it may become impossible to make measurements, or, damage may occur. Take measures such as the following to prevent condensation.
|
• Ensure that the ambient temperature is the same |
|
NOTICE |
or lower than the fluid temperature. |
|
• Remove moisture via air conditioning |
||
|
•Separate the sensor 30 cm or more from the cooling pipes using the connector pipe.
6.When conducting maintenance, use a soft brush so as not to damage items such as the detection surface or the O-Ring.
7.When replacing the O-Ring, clean all of the debris from the surface that will be in contact with the O-Ring.

Piping/Installation
Piping
•Use the adapter for matching with the diameter of the piping.
•When using a replacement adapter, attach the O-Ring included with the Main Unit to the groove of the G3/4 female screw part. (Refer to the diagram below)

•Inquire to us when connecting the pipes directly using the GP-M Series with a G3/4 female screw.
•The body may be rotated horizontally to 330°. When rotating, hold the clasp in place with something such as a wrench.

Precautions when installing
z Attaching the coupling
The recommended tightening torque when installing the adapter to the main body of the sensor is 20 N•m. It is recommended to apply grease to the G3/4 screw part in order to avoid scorching.
z Grounding of metal parts
The metal parts of the main body, the internal circuits 0 V are insulated.
z Other precautions
• Regardless of whether the power of the device is ON or OFF, do not touch the main part of the pressure detector, if the if the pressure detector is touched, damage may occur due to static electricity.
•If using a non-conductive liquid such as oil, and plastic piping are used, the risk of an offset change will become greater. In such a case, it is recommended to ground the metal housing.
•In the case that noise causes malfunction, grounding the metal housing may improve performance.
•After installation, conduct an atmospheric correction by making the applied pressure the same as regular room pressure. (Refer to page 10)
•When there is condensation,
separate the sensor from cooling pipe by at least 30 cm using the connecting pipe.
