[CA] [DG11] ST5000 plus faulty

[Derek - Raymarine - Moderator]

Hi jonfinch,
Thankyou for your enquiry.

SO to be clear, the drive unit that you have installed is the mechanical linear drive attached direct to the rudder quadrant, you have a rudder reference unit, ST5000+ control head and a fluxgate compass.

The rudder display on the ST5000+ control unit should be very stable in STANDBY and move only when the rudder is moved. If the rudder position is moving even when the rudder is held stationary, then check the compass is working correctly and if yes, then the ST5000+ control unit has a fault.

To update this system, the components required would be the EV1 sensor, the ACU200 and a p70s control unit. The compass and the Rudder reference unit should be changed, the existing linear drive can be re-used - but worth checking or having it serviced to make sure the clutch etc are all still in good condition.

In addition to this, the new installation of the Evolution autopilot can be connected to the SeaTalk of your existing instruments through the E22158 STng to SeaTalk converter.

Regards
Derek
