The previous Alarms (Power Loss, Sash Height, and Blower Failure) can occur on any
Axiom Type C1 cabinet whether it is operating in A-mode or B-mode.
The following Alarms will only occur on the Axiom Type C1 cabinet when operating in B-
mode, as these alarms are only related to build exhaust problems.
Exhaust Airflow Check
This is not an Alarm. When operating in B-mode,
and the blower is turned on, the cabinet will wait
1 minute until proper building exhaust airflow is
established before turning on the cabinet’s
internal blowers. During this waiting period, the
display will show Figure 6-27.
Starting Exhaust Alarm
When operating in B-mode, and sufficient building
exhaust airflow is never achieved during the 1
minute blower starting period, this alarm will be
displayed. Press [BLOWER] on the keypad to
clear the alarm.
Running Exhaust Alarm – Active Protection
When operating in B-mode, after the blowers are
successfully started, and the building exhaust airflow
drops below the minimum safe level, this alarm will
be displayed.
Once this alarm activates, the cabinet’s blowers will
continue to run - maintaining safe airflow in the
cabinet for the Active Protection time (up to 5
minutes) selected in the Tools Submenu.
Press [BLOWER] on the keypad to clear the alarm.
