Precautions for wiring CAUTION NOTICE 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 wet hands. It may cause electric shock. 4. When wiring, confirm the pin position. 5. Use the GP-M Series within the rated range.
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. NOTICE • Ensure that the ambient temperature is the same 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.

• The atmospheric pressure correction will be reflected on the analog output. Key Lock Function for preventing operation error. Activate/Deactivate Key Lock From the main screen, press and hold the MODE button and the U button (or the V button) simultaneously. If “.QE” is displayed while blinking, the Key Lock is enabled. With the same operation it can be disabled (“WP.” will be displayed while blinking).
Changing the Setting Value of Output 1 Change the setting value of output 1. The changing of setting values of output 2 is done by pressing and holding the MODE button.

Explanation of All Functions Detection mode and setting value The GP-M Series has two types of detection modes which are described below. When the selected function of output 2 is QWV (control output), the output 1 and output 2 can be set separately. Hysteresis mode (*PQ/*P%) Considering 5R T2 = hysteresis, it is the mode for changing the setting value when ON and when OFF. • When the output is OFF (right diagram 1), and the measured 52 value becomes more 52 than it will turn on (right diagram 2).
If *;5 is fixed at 0.5% of F.S., the presence or absence of hysterisis can be selected by the extended function (page 16). Reference The name of the setting values depending on the mode and output are as follows. Output Detection Mode Output 1 Output 2 Output 1 Output 2 when choosing hysteresis mode when choosing window mode Switch on Switch off point point 52 T2 52 * T2 * (* (. (. * (* * * Selection is possible when the selection function of output 2 (control output) is QWV.
Offset correction Concerning the value at the time of Display value Solid line: shipping, there may be as much condition at shipping as ±10%F.S. offset correction. This activates in the case of a margin of error in the displayed pressure value and the actual pressure value. ±10%F.S. Pressure value The pressure value after the offset correction is displayed on the setting screen and can be adjusted with the UV buttons.
Reference Time chart Output judgment ON OFF Control output ON after delay OFF F5 /F5 (ON delay) FT /FT (OFF delay) Responsiveness The time until 100% response of the internal judgment value can be set from within the range of 3 to 5000 (ms). The response time of the analog output (90% response) will be an additional 2 ms from this point. Power Save Mode When QP is selected, if the key operation does not occur for 15 seconds (Power Save) will be displayed.
Error Display and Countermeasures Error display 'T% Q. W. 'T2 'T' 'T5 Cause Measures At the time of atmospheric pressure correction there is ±10% F.S. applied pressure. There is too much current flowing through the control output. Outside possible display range (above) Outside possible display range (below) Return the air to the room pressure, once again set the sensitivity setting. Check the load, and return to the rated range. Return to the rated pressure range.
