Alarm and error messages
Description
Low PPO2
The ”
LOW PPO2
” alarm message appears if the PPO2 is lower than .40
for more than 10 seconds. With the first warning it is necessary to confirm
this by pressing the right button. If, during the same dive, the PPO2 should
once again be too low then it is not necessary to confirm this again (see se-
cond image). The PPO2 values and the ”
Low PPO2
” warning flash in
red
.
Another cause for this alarm message is shown in the third image. Two
sensors with comparable values are not available. It is therefore not
possible for the controller to determine which value is correct, and the
actual PPO2 is thus unknown. In this instance the average PPO2 is calcu-
lated as 0.00. Because 0.00 is lower than 0.40, the ”
Low PPO2
” alarm
message will also appear.
Low Battery EXT
This alarm message appears if the voltage (< 6.6v for more than 30
seconds) of the two batteries for the solenoid is too low . The solenoid
continues to function, but the batteries must both be replaced prior to
the next dive.
Low Battery INT
This alarm indicates that the controller battery must be replaced immedia-
tely. It appears if the battery voltage drops below the minimal volts for
more than 30 seconds. The battery symbol also flashes
red
.
