- 47 - RM-5000

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 <<Auto-Reset>>.

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.
