If the rudder drives continuously to one side, switch off
the powering at the breaker at once. Check the
mechanical and electrical installation. There is a
Troubleshooting Guide in the 930 609/619 Installation
Guide which may help.
If the rudder continuously ‘hunts’ about amidships, remove as
much freeplay as possible from the steering and Rudder Feedback
Unit linkage. This also occurs on Power Steering systems
particularly if the steering pump is plumbed with flexible hose.
If that does not stop it, increase the Rudder Deadband setting, see
section 7.1.
Check that when you press the key, the motor drives the rudder
to Starboard and when you press the key, the rudder drives to
Port.
Press the OFF key to return to Standby Mode. You are now ready
to start the Sea Trials Installation.
It is advisable to record the optimised settings, in case
they are accidentally changed at any time.
