Using The Autopilot In An Evc System - Simrad AP44 Quick Manual

value is set too high the overshoot will increase and the
steering will be unstable.
- CCA. The CCA is an angle that is added to or subtracted from
the set course. With this parameter you can make the boat yaw
around the reference depth with lazy-s movements. The larger
the CCA the bigger yawing will be allowed. If the CCA is set to
zero there is no S-ing.
- Ref. depth. This is the reference depth for the DCT function.
When DCT is initiated the autopilot reads the current depth
and set this as the reference depth. The reference depth can be
changed when the function is running.
Ú Note:
If depth data is lost during DCT the autopilot will
automatically switch to AUTO mode.
It is recommended to turn ON the AP Depth Data Missing alarm
when using DCT. When this alarm is activated an alarm will be
raised if the depth data is lost during DCT.

Using the autopilot in an EVC system

When the AP44 is connected to an EVC system via the SG05, you
can take manual control of the steering regardless of the autopilot
mode.
The mode indicator is replaced by a dash to indicate EVC override.
The system returns to AP44 control in Standby mode if no rudder
command is given from the EVC system within a predefined period.
