Digital Gauge Frequently Asked Questions
Question number FAQ-0064
Troubleshooting - Regarding the Flickering Display
- The display of measurement errors (blinking) is the same function across all models of the DG4000 series.
- If a measurement error occurs, the display will blink and the 'BCD out' error output will turn on, but this is not a malfunction of the device.
- For safety and noise reduction, please be sure to ground the terminal.
Causes and countermeasures for measurement errors.
| cause | countermeasure |
|---|---|
| If the movement speed of the sensor's spindle exceeds the maximum response speed specified for the GS sensor. | Please lower the movement speed of the measured object or the sensor's movement speed so that the spindle movement speed of the sensor is below the maximum response speed. |
| When the tip of the spindle makes contact with the measured object, the impact may exceed the maximum response speed. | same as above |
| In the case where the sensor input signal is affected by external noise. | (1) If the sensor signal cable is wired near a noise source (such as a motor or solenoid), please change the wiring route. (2) Do not make the sensor signal cable longer than necessary. (3) Ensure proper grounding of this device. Use soft copper wire of 2mm 2 or more for grounding wiring within a length of 20m. |
| If the "90° phase difference" of the sensor output signal is misaligned (when the zero point display is not zero for each measurement and gradually increases in value) | Please replace the sensor. |
| If the input and output signals of the BCD connector are affected by external noise (Does it return to normal when the BCD connector is removed?) | (1) Use shielded wire for the signal code, aiming for about 3m, and do not make it longer than necessary. (2) If the sensor signal cable is wired near noise sources (such as motors or solenoid valves), please change the wiring route. |
| Terminal block: When the input signal is affected by external noise. | same as above |
(2) Confirmation of GS sensor failure
| cause | countermeasure |
|---|---|
| If the spindle part of the GS sensor is moved slowly up and down with a finger and the display does not count up or down. | Please replace the GS sensor. |
| If, after resetting at the reference point and moving the spindle up and down to return to the reference point, the display does not show zero and instead retains a value. | |
| The spindle does not move smoothly. |
Recovery from measurement error
After implementing each measure and eliminating the causes, please press the RESET button on the front panel of this device to reset it. For other reset methods such as terminal input, please refer to the specifications of each model.
