User manual

The mid-water obstacle ramming behavior can be disabled during upward profiles by
setting the shallow error below (deeper than) the deep pressure. Range is 0.0 dbar to 6000.0 dbar.
Deep Error <E>
Deep error defines a pressure above (more shallow than) the deep pressure stop. If the
firmware detects a zero pressure rate while inside the deep error window on a downward profile,
the MMP stops profiling. The mid-water obstacle ramming behavior is not triggered.
The deep error is ignored on upward profiles. The deep error allows the operator to
compensate for mooring dynamics and uncertainty in the actual depth of the bottom. If the
mooring dynamics are less than anticipated or if the bottom is shallower than expected, the deep
bumper may rise above the deep pressure stop. In these cases the obstacle ramming behavior
would be undesirable. The deep error is chosen based on calculations of the dynamic mooring
behavior and knowledge of the possible depth error. Inside that window a zero pressure rate is
interpreted as the deep bumper, and the ramming behavior is not triggered. The profile
terminates as if the deep pressure stop had been detected. Range is 0.0 dbar to 6000.0 dbar.
Profile Time Limit <T>
Profile time limit is the maximum time allowed for MMP motion. The firmware displays
a default Profile Time Limit after the shallow and deep pressure stops are entered (this should be
changed for the specific deployment). When the firmware cannot detect a pressure or pressure
rate based stop (and the battery voltage and motor current are within their prescribed limits), the
profile terminates based on elapsed travel time.

If the time limit expires while the MMP is profiling, the firmware halts MMP motion.
The sensor data acquisition continues for two minutes before the firmware stops logging and
