Start up
5.5.1
AFA4000/E
The AFA4000/E must be field-calibrated once the room air supply and exhaust is proportionally
balanced.
When the unit is powered up, the following sequence of events occurs:
1.
The alarm performs a self-test of its functions and audible alarm which takes approximately
5 seconds.
2.
At the end of the delay, the unit will do one of two things:
•
When the Airflow monitor has been calibrated, the unit enters normal operating mode.
The monitor displays airflow velocity, LEDs and the audible alarm is enabled.
•
If the Airflow monitor has not been calibrated, the unit displays the message
Requires
set up, press Mute to continue
.
Note: If the unit has been fitted with a Fan Stop/Start pushbutton, the controller can be set to
Run mode before it is calibrated to allow the fan to be started. To enter the menu from
the Run screen, press and hold the Mute button for 5 seconds or until the main menu
appears.
Note: During set-up, all alarms and output relays are inhibited.
Follow the instructions in the
Calibration
section (section 7.1).
5.5.2
AFA4000/E/AS
The AFA4000/E/AS must be field-calibrated once the room air supply and exhaust is
proportionally balanced.
When the unit is powered up, the following sequence of events occurs:
1.
The alarm performs a self-test of its functions and audible alarm which takes approximately
5 seconds.
2.
At the end of the delay, the unit will do one of five things:
•
When the Airflow monitor has been calibrated, the unit enters normal operating mode
(Run). The monitor displays airflow velocity, LEDs and the audible alarm is enabled.
•
When the Airflow monitor has not been calibrated, the unit displays the message
Requires set up, press Mute to continue
