AFA1000/2 MK2 Airflow Monitor
Installation & Operating Manual
2.2 Display Features
The Airflow Monitor display has the following features:
The digital display is a backlit, full colour high resolution graphic unit with a visual display area of
approx 45 x 34mm. The display operates through the software allowing the generation of figures,
wording and icons. The display background colour can be provided as either Blue or Black.
The display shows the fume cupboard face velocity in m/sec or fpm when enabled or the alternative
with no velocity reading but showing AIR FAIL / AIR SAFE as continuous display. All of the above are
configurable via the alarm key pad.
The displayed face velocity colour will change when in an alarm condition:-
Air Safe = White / Low or High Air Alarm = Red / Warning Air Alarm = Amber.
An ‘event time line’ segmented into 60 x 1 minute segments will scroll across the display (when
enabled) .This takes the form of a graphical scale ranged over 0-1.00 m/sec that will progress from the
right hand side to the left hand side of the screen – representing the airflow value at each segment.
The segment colour will change if the value is in the range of an airflow alarm:-
Air Safe = White / Low or High Air Alarm = Red / Warning Air Alarm = Amber.
The alternative to the event time line is a dynamic ‘bar graph’ representing the airflow velocity.
The display shows an up or down arrow Icon in the bottom right hand corner of the screen when an
input function is set to Hi / Lo (2 speed operation). The Up arrow indicates High speed and the Down
arrow indicates Low speed.
The display shows a Horn icon (with line through it) when the audible alarm is in the Muted condition
The display backlight will dim to a fixed low level when certain functions are active to save energy:-
Fan Off - display backlight reduces until Fan On is selected.
Backlight will resume to normal level whilst Set Up or Diagnostics menus are accessed.
Setback Input is active - display backlight reduces until input is not active.
Backlight will resume to normal level whilst Set Up or Diagnostics menus are accessed.
