6.11 Silencing an Alarm
You can temporarily silence an alarm by pressing the control dial. The alarm is silenced for 60 seconds and
then sounds again if the cause of the alarm has not been corrected. If another alarm occurs while the silence
period is active, the audible alarm portion of the new alarm will not sound until the silence period expires.
When the silence period expires, the alarm’s audible alarm is reactivated if the alarm condition has not be cor-
rected.
6.12 Alarm Message Screens
When an alarm message is activated, an alarm screen is displayed, showing the text or icon specific to the
most recent, highest priority alarm.
Pressing the control dial once will silence the audible alarm. Press the control dial again to remove the alarm
screen from the display. Resetting the alarm allows you to return to the previous screen. If multiple alarms
occur during the same period of time, the alarm screen will display the higher priority alarm (higher priority
alarms take precedence over lower priority alarms).
6.13 What to Do When an Alarm Occurs
Complete the following steps when an alarm occurs:
1. Listen to the audible alarm and look at the alarm indicators and whether the LED is solid or flashing.
2. Look at the display to check the alarm message that appears on-screen and whether it is red or yel-
low.
3. Press the control dial to temporarily silence the audible alarm. Or, press the control dial twice to ac-
knowledge and remove the alarm from the screen. In case of loss of power, use the control dial to
both silence and terminate the alarm.
4. Look up the alarm in the alarm descriptions in this chapter to determine the source of the alarm and
the appropriate action.
