What to do if Riken Keiki Gas Detectors trigger alarm with no gas leak?
- V
  Victor ChoiAug 13, 2025
  If your Riken Keiki Gas Detectors trigger a gas alarm even without a gas leak or abnormalities at the detection point, it might be due to the presence of interference gas. For information on actions such as removal of filter, please contact RIKEN KEIKI. Another cause could be disturbance by noise; try turning off and restarting the detector head, and if the issue persists, take measures to eliminate the noise. A sudden change in the environment might also be the reason, so take preventive actions to eliminate such changes.

How to troubleshoot Riken Keiki GD-D58-AC that won't turn on?
- S
  Shane HicksAug 17, 2025
  If your Riken Keiki Gas Detectors won't turn on, ensure the wiring is correctly connected and the terminal plate is properly attached. Also, check for any abnormalities or momentary blackouts in the power supply system, providing the rated voltage and considering measures like a UPS, power supply line filter, or insulation transformer. Cable abnormalities such as open circuits, disconnections, or short circuits could also be the cause; inspect the wiring of the detector head and related devices.

  If your Riken Keiki Gas Detectors reading rises (or drops) and remains so, it could be due to drifting of the sensor output; try performing a zero adjustment. Alternatively, the presence of interference gas may be the cause. For information on actions such as removal filter, please contact RIKEN KEIKI. A slow leak could also be responsible, so take remedial measures similar to those for a gas alarm. Environmental changes can also cause this issue; perform a zero adjustment.

Why is span adjustment impossible on Riken Keiki Gas Detectors?
- A
  Andrew NelsonSep 1, 2025
  If you cannot perform span adjustment on your Riken Keiki Gas Detectors, it might be due to an improper calibration gas concentration. Ensure you are using the proper calibration gas. Another potential cause is sensor sensitivity deterioration; if this is the case, replace the sensor with a new one.

What does low flow rate abnormality E-5 mean for Riken Keiki GD-D58-AC?
- J
  Jay SpenceSep 5, 2025
  If your Riken Keiki Gas Detectors display a low flow rate abnormality E-5, it could be due to a low flow rate. Check the flow rate to ensure it is adequate. Alternatively, there may be faults with the flow sensor, in which case you should replace the sensor with a new one.
