The Clearance pre-warning alarms are used to warn you if a
trawl or another towed object either moves too close to the
bottom, or lifts too far off the bottom. You must have the echo
sounder switched on to use this alarm. To enable it, set the
minimum limit to the minimum allowed distance between the
footrope and the bottom, and/or the maximum limit to the
maximum allowed distance between the footrope and the
bottom. Then, switch one or both alarms to ON. The alarm is
triggered if the reading from a
Depth sensor mounted on the
footrope (or a manual depth marker) exceeds one of the defined
limits. To use this alarm for a single towed object, select the
Depth sensor as a
Foot rope sensor in the Trawl info dialogue.
Clearance pre-warning, min : Set minimum alarm limit, and
select ON when you wish to enable the alarm.
Clearance pre-warning, max : Set maximum alarm limit, and
select ON when you wish to enable the alarm.
