Variable Ascent Rate; Ascent Rate Warning; Ascent Rate Alarm - Aeris Manta Operating Manual

VARIABLE ASCE T RATE
Alerts associated with Ascent Rate are based upon 2 sets of speeds which change
at a reference depth of 60 FT (18 ).
WAR I G: At depths greater than 60 FT (18 M), Ascent Rates
should not exceed 60 FPM (18 MPM). At depths of 60 FT (18
M) and shallower, Rates should not exceed 30 FPM (9 MPM).

Ascent Rate Warning

At depths deeper than 60 FT (18 ), a Warning (Fig. 67) will be given when
Ascent Rates exceed 50 FP (15 P ). The message SLOW > SLOW will scroll
until the Ascent is slowed. At 60 FT (18 ) and shallower, the Warning will be
given when Ascent Rates exceed 25 FP (7.5 P ).

Ascent Rate Alarm

At depths deeper than 60 FT (18 ), an Alarm will sound when Ascent Rates
exceed 60 FP (20 P ).
At 60 FT (18 ) and shallower, the Alarm will sound when
Ascent Rates exceed 30 FP (10 P ).
The Audible will sound, the red LED will flash, and the message
SLOW > SLOW will scroll on/off at the top of the screen. The
Audible and LED will stop when acknowledged with the S
button or when the Ascent is slowed. After acknowledged, the
message SLOW > SLOW will continue to scroll until the Ascent
is slowed below the Alarm rate.
