LCD Alerts and
Displays
This section describes various alerts and displays.
•
Gas Warning and Alarm Alerts:
– Both gas warnings and alarms blink the specific gas type that is in alert.
Audible, visual, and vibrating alarms activate and the concentration/value of
the sensor in alarm is indicated.
– If a Gas Type Label blinks with no alarm present, the sensor is detecting a
negative drift. Perform a Zero Calibration to clear the drift. See “Zero
Calibration” on page 39.
– If the option to Allow Use with Failed Sensors is enabled using the SGM
software, the device displays FAL in place of the reading for that particular
sensor.
Warning: The option of Allow Use with Failed Sensors is discouraged. Operating the
device with a failed sensor will not provide full monitoring capabilities. Use this
option only after careful consideration and understanding of the device’s reduced
monitoring capabilities and following local regulations. Failure to understand how
operating the device with a failed sensor may lead to death or injury.
•
Low Battery – The battery charge icon blinks and the device activates the visual,
audible, and vibratory alarms when a battery becomes low. Low battery conditions
can be silenced by pressing the left Operation Button. You should immediately exit
the environment and charge the device as soon as a low battery alarm is indicated.
