What to do if Riken Keiki Security System has abnormal operations?
To address abnormal operations in your Riken Keiki Security System, first turn off and then restart the indicator/alarm unit. If this issue occurs frequently, take steps to eliminate any potential sources of noise.
Why is my Riken Keiki Security System responding slowly?
To resolve a slow response issue with your Riken Keiki Security System, start by replacing the dust filter if it's clogged. Inspect the suction or exhaust tubes for any bends or clogs and fix them accordingly. Also, check for any condensation inside the suction tube and rectify any issues. Finally, if the sensor sensitivity has deteriorated, replace the sensor unit with a new one.
Why span adjustment is impossible in Riken Keiki Security System?
If you are unable to perform span adjustment on your Riken Keiki Security System, verify that you are using the correct calibration gas. If the issue persists, the sensor sensitivity may have deteriorated, requiring a sensor replacement.
What to do if the reading rises (drops) on Riken Keiki GP-6001 Security System?
If the reading on your Riken Keiki Security System rises or drops and remains that way, perform a zero adjustment (fresh air adjustment) to correct for sensor output drift. If interference gas is present, contact Riken Keiki for information on actions, such as removal filter. Address any slow leaks by taking actions similar to those for a gas alarm. Also, perform a zero adjustment to compensate for environmental changes.
Why Riken Keiki Security System triggers gas alarm with no leak?
If your Riken Keiki Security System triggers a gas alarm without a gas leak or other abnormalities, it could be due to interference gas. In this case, contact Riken Keiki for information on actions, such as removal filter. Another cause might be disturbance by noise; try turning off and restarting the indicator/alarm unit, and if the issue persists, take measures to eliminate the noise. A sudden change in the environment may also be the reason and you must take any preventive actions to eliminate them.
How to fix cable open-circuit in Riken Keiki GP-6001?
To fix a cable open-circuit between the indicator/alarm unit and the detector head of your Riken Keiki Security System, restore the cable connection.
What causes sensor abnormalities E-1A SENSOR in Riken Keiki GP-6001?
To address sensor abnormalities E-1A SENSOR on your Riken Keiki Security System (GP-6001/NC-6001/GH-6001/OX-6001 only), check the harness connections between the amplifier PCB and the main PCB. If there's a sensor open-circuit or short-circuit in the detector head, properly connect the cable between the indicator/alarm unit and the detector head (sensor), or replace the sensor. For abnormalities in current supply to the sensor, readjust the heater current. If there are abnormalities in voltage supply, readjust the load voltage. Finally, for zero follower abnormalities, perform the zero adjustment.
What to do if span adjustment is impossible in Riken Keiki GP-6001?
If you are unable to perform span adjustment on your Riken Keiki Security System, verify that you are using the proper calibration gas. If the issue persists, the sensor sensitivity may have deteriorated, requiring a sensor replacement.
