Responding to Alarms

When an alarm condition is triggered, the Portable Air Conditioning Unit alerts you through the:

•Alarm beeper

• Alarm or warning LED

• Active alarm screen

• Alarm/Event log

Depending on the severity of the alarm, you may need to take action to clear the alarm condition or to

resume operation.

Silencing the alarm beeper

Path: Main Menu > Alarms & Logging > Alarm Beeper.

An active alarm causes a beeping sound from the display interface (one short tone in 30 second

intervals) until the alarm is cleared or the beeper is silenced. To silence the beeper, follow the path

above and choose one of the following options:

• Silence Active Alarm

• Silence All Alarms (you must re-activate the beeper to get future audible alarm alerts).

Warning or alarm LED

When an alarm condition occurs, the check log LED and either the warning LED or alarm LED are

activated. The alarm and warning LEDs cannot be deactivated manually; the alarm condition must be

cleared to deactivate them.

Warning LED. Requires action, but is not critical to unit operation.

Alarm LED. Requires action to continue unit operation.

See “Alarm messages” on page 30 for a listing of alarms and the actions required to

clear them.

See “Beeper Volume” on page 23 for information about changing the beeper volume.
