Manual Work Mode - ComNav Commander P2 Installation & Operation Manual

ComNav Commander P2 Installation & Operation
When WORK mode is engaged, the Rudder Scale Factor will multiply the Rudder Gain
setting. Normally the rudder is moved an amount proportional to the course error detected
(i.e., the error times the Rudder Gain); in WORK mode, that calculation will also be multiplied
by the Scale Factor, resulting in larger rudder movements for a given course error. The
Rudder Scale Factor is entered on the Work menu (see page 137).

If the user is not satisfied with the fixed helm bias determined by the Autopilot at the onset of

can change this value to suit using the COURSE CHANGE knob. This feature is useful in
order to accommodate changing load or sea conditions.
As mentioned earlier, WORK mode will automatically be disengaged if the vessel's speed
rises above the Work Trip Point set by the user. While it is disengaged, all normal features
such as automatic trim and course alarm will be operational.

Other effects take place in WORK mode too.

Finally, the built-in course alarm will be disabled the entire time WORK mode is
engaged.

Caution!
When Manual WORK mode is engaged, large rudder
movements may occur. If your vessel is traveling too fast, these rudder
movements may affect the stability of the vessel. Do not engage Manual
WORK mode without first ensuring that it is safe to do so and that the
vessel speed is appropriate for using WORK mode.
