OPERATION
On power-up the Breathing Air system is in the normal operating mode. Information
from the pressure sensor or from the datalink interface is processed and displayed.
Operator input is necessary only when accessing program information.
The digital display indicates bottle pressure above 500 PSI in increments of 10.
(If the display module is programmed for the units of measure to be Bar, it shows one
digit to the right of the decimal point.)
The bar graph display shows the percentage of air in the bottle in ten percent
increments. Press the MENU button to display the actual percent of air left in the bottle.
Low Air Warning
The Low Air warning triggers when the air in the bottle drops below the low air
warning setting (refer to Programming Section code 316). Both audible and visual
alarms are generated. Pressing the SILENCE button suppress the audible alarm. The
visual alarm includes the bar graph ashing and LoAir warning message showing in
the display. To clear the visual alarm the air pressure must rise at least 30 PSI above
the low air warning set point.
On power-up with the bottle pressure less than 5% full, the audio alarm is disabled.
If the pressure is between 5% and the low air warning pressure setting the alarm sounds
one time for ten seconds.
Program Information
Pressing the MENU button allows the operator to see the exact percent of air
remaining in the bottle.
Datalink Interface
The datalink interface provides a way of connecting multiple display modules on
a shared data bus. The correct ID number must be programmed for each module (see
Program Code Descriptions).
Primary Display Module
Primary display modules receive input from the pressure sensor. At power up all
programming information is sent to all remote displays on the datalink. An E212 error
code shows if the pressure sensor input is out of range.
Remote Display Module
Remote display modules receive all information from the primary display via the
datalink. An E201 error code shows if the datalink input is missing.
