Never use this product for prevention of accidents which damage a WARNING human life or properties or for safety maintenance. Connection ・The GP-X series is configured to satisfy the specification with the combination of the sensor head and the controller. Use the sensor head and controller in combination without fail; with other combinations, not only may the specifications may not be satisfied but also failure may result. ・Turn the controller off before mounting or removing the sensor head and controller. ・Note that the cables will be damaged if they are pulled. Power Supply ・Wait 15 minutes (or 20 minutes with GP-X3S and GP-X5S) after the power is turned on before operation is started. There may be a variation in the measurements immediately after power-on because the power circuit is not stable. ・There is a muting time of about two seconds after the power is turned on. Take care that wrong wiring may damage the sensor. ・Verify that the supply voltage variation is within the rating. ・If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground. ・Make sure to use an isolation transformer for the DC power supply. If an auto-transformer (single winding transformer) is used, this product or the power supply may get damaged. ・In case a surge is generated in the used power supply, connect a surge absorber to the supply and absorb the surge. Wiring ・Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction. ・Make sure that the power supply is off while wiring. ・The analog voltage output is incorporated with a short circuit protection circuit. Do not connect it directly to a power supply or a capacitive load. ・Be careful to avoid statically charging connectors during wiring work. A failure may result. ・Use the exclusive extension cable for cable extension of the sensor head. (Overall length: 10m) 2 Environment ・Take care that the sensor does not come in direct contact with water, oil, grease, or organic solvents, such as, thinner, etc. ・In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this product, connect the frame ground (F.G.) terminal of the equipment to an actual ground. ・Take care that stress is not directly applied to the cable joint. ・This sensor is for indoor use only. Compatibility ・In case the sensor head is broken, the sensor head replacement is possible with same model. (However, entering a characteristics code (ID code) and calibration are required) Intended Products for CE Marking ・The models listed under 'Chapter 8 Specifications and Dimensions' come with CE Marking.

If another variation of the application mode is selected, an error is displayed. 4: The interference prevention function becomes valid when interference I/O cables are connected at the external input terminals between controllers. 5: If the detection range is exceeded even though the setting is valid as a command instruction character string, error "20" is sent back. 6: Memory switching cannot be performed unless "panel" is selected for the memory switching method. If "external input" is selected, error "20" is sent back. Chapter 6 7: The "system reset" command is to restart the controller program. (The sensor goes into the same state as restarting up state. 8: After initialization of settings, the sensor displays the detection state since it is automatically reset. The sensor having the 1.10 or later version software does not require reset of the power supply. Initialization using an RS-232C command does not initialize the communication conditions and the controller address. 9: Data buffering With data buffering, sample data collected in the GP-X series at high speed temporarily accumulates in the controller in reference to trigger conditions and, upon completion of accumulation, the data is loaded via RS-232C communication. About 120,000 points of data can be accumulated. (Equivalent to about 3 sec. at a sampling frequency of 25㱘s) Use optional intelligent monitor software (GP-XAiM) to enter data buffering settings and perform data collection easily. For the usage of various commands and details of the intelligent monitor software (GP-XAiM), contact us. 128 Examples of Application of RS-232C Commands Example 1: Load the current displayed value from controller address 0.
