AIR FLOW DISPLAY
The FAAST XS system uses ultrasonic airflow sensing and displays the status in
real time on the user interface. The air flow display consists of 10 green LEDs at
the bottom of the device to display current flow balance as shown in Figure 8.
The green segments on the air flow pendulum indicate how close the current
air flow is to a high or low fault threshold. The default threshold for a fault
condition is + or – 20% from airflow baseline. This fault threshold is configu-
rable using the PipeIQ software. During normal operation two adjacent indica-
tors are green and correspond to the current air flow entering the detector for
the inlet being displayed. When air flow is balanced, these two indicators will
be centered in the pendulum. As air flow increases or decreases, the indicators
will move to the left in the case of a low flow condition, or right in the case of
a high flow condition. A flow fault occurs when the flow boundary threshold
has been exceeded longer than the flow fault delay period. The fault relay will
be set when this occurs.
Detailed air flow information can also be read by accessing the ‘Air Flow’
menu in the device’s LCD display.
FAULT DISPLAY
The FAAST XS user interface displays faults in two ways, through amber LEDs
on the right side of the user interface, and also on the LCD screen. The four
Fault LEDs are:

If the General Fault LED is ON, the fault condition will be shown on the LCD
display under the Active Faults menu. The possible fault conditions are:

DESCRIPTION
ACTIVATED RELAY
Low Flow Fault
Device air flow below the
boundary and delay programed
by the user.
Fault
Configuration
Configuration of device with
configuration software has
failed.
Fault
Device was interrupted with a
power loss during configura-
tion. A Reset will clear this
fault and device will revert
back to it’s last good configu-
ration.
Fault
Device is new and has not
been configured.
Fault
Device has corrupt configura-
tion and is unable to operate.
Fault
Drift Blue Fault
Device blue signal has reached
the long term drift limit.
Fault
IR Laser Drift Fault Device IR Laser signal has
reached the long term drift
limit.
