5-2. Fault alarm activation

Fault alarm:

Triggered when an abnormality is detected in the gas detector.

Fault alarm activation:

Self-latching

Alarm display:

Notifies by lighting of the alarm lamp, sounding of the buzzer and displaying the
detail.

Alarm types:

System abnormalities, sensor abnormalities, calibration abnormalities, low
battery voltage, low flow rate and clock abnormalities

Alarm type

System abnormalities, sensor abnormalities, calibration abnormalities, low
battery voltage, low flow rate and clock abnormalities

Alarm lamp

Blinks at about 1 second intervals.

Buzzer

Sounds intermittently at about 1 second intervals.

LCD display

Displays an error message

NOTE



Of the fault alarms, only the low flow rate alarm "FAIL - LOW FLOW" and "FAIL - CLOCK" can be
reset by pressing the RESET button. For other fault alarms, turn off the power and then promptly
contact RIKEN KEIKI.



For information on malfunctions (error messages), see "8. Troubleshooting".
