Work-Mode - Simrad AP35 Instruction Manual

2.13 WORK-mode

The WORK-mode is an automatic steering mode to be used under
operational conditions different from those normally found when a vessel is
in transit on a preset course. Examples are trawling, towing, trolling on one
engine, slow speed etc.
First Press
At such incidents some boats may need a rudder off-set when steered by
hand. By selecting WORK-mode directly from STBY-mode the rudder off-
set is maintained and becomes the TRIM value.
When in WORK mode a quick double press on the WORK button will
access the TRIM display and the rotary course dial can then be used to adjust
the trim value if needed. The (manual) trim compensates for the autotrim
which needs time to build up the appropriate rudder off-set. The TRIM
setting is not stored.
A different RUDDER (GAIN) setting may be preferred in WORK mode as
compared to that in AUTO (Lo)-mode. A second quick double press on the
WORK button following that for the TRIM display will give access to the
RUDDER display. The RUDDER value can then be set by the course dial.
The RUDDER value set in WORK mode will be stored in the AP35 memory
and is automatically recalled when returning to WORK mode.
The LO (speed) parameters of Counter Rudder (C-RUDD) and Autotrim are
automatically selected in WORK mode. The autotrim function and the Off-
course alarm are controlled by speed input and are automatically turned off
at speeds below 2 kts. If no speed input is provided the autotrim is
permanently on and the Off-course alarm operates as in AUTO mode.
If you prefer to have complete manual control of the rudder trim in WORK
mode, the autotrim can be permanently disabled at the installation setup.
From software version V1R2 onwards the off course alarm is permanently
disabled in Work mode. See your s.w. version on initial start-up.
Note !
Pair-trawling requires manual trim only, and the autotrim should be
permanently disabled at the installation setup.
