In case of responding to a leaked gas
When a gas alarm is triggered, take actions in accordance with your management rules of gas alarm.
Normally, take the following actions.
• Check the reading of the indicator/alarm unit.
NOTE
If a gas leak is momentary, the reading may already have dropped when you check it. In addition, when
the alarm is triggered by noise or other incidental conditions other than a gas, the reading may have
already dropped.
• Based on your management rules of gas alarm, no one should be allowed to access the monitored zone
to ensure safety.
• If the Gas Concentration Display continues to be shown, close the main valve of the gas, and then check
that the gas concentration reading is dropped.
• Assuming that gases remain, wear protective equipment to avoid dangers and go to the gas leak point,
and then check if gases remain using a portable gas detector etc.
• If you can determine that the point is free from dangers, take actions to fix the gas leak.
6-2. Fault alarm activation
A fault alarm is triggered when the indicator/alarm unit detects abnormalities <>.
After a fault alarm is triggered, the FAULT lamp (yellow) blinks and an error message is displayed on the
LCD. Determine the causes and take appropriate actions.
After the indicator/alarm unit is successfully returned from the fault, it restarts with the process normally
performed right after it is turned on (initial clear).
If the indicator/alarm unit has problems and is repeatedly malfunctioning, contact RIKEN KEIKI immediately.
