26.Go back to the [DOCKSIDE SETUP] menu, select [RUDDER TEST] then push the
knob. The cursor is selecting [NO]; push the knob. Select [YES] then push the knob to
start the test.
The rudder test automatically detects drive unit type as follows:
Successful detection
SOLENOID: The test automatically continues.
REVERSIBLE: The following menu appears. Select correct drive unit type with the
Course control knob and push the knob. Then, the test continues.
Note : IN PORT1 and INPORT2 are disabled when SAFE HELM is selected.
Failed detection
“RUDDER TEST FAILED” appears. The rudder test is discontinued.
When the rudder test is finished, the message "RUDDER TEST COMPLETED."
appears.
The results are shown on the screen as follows:
[DRIVE TYPE]: [REVERSIBLE12V](or 24V), [SAFE HELM 12V](or 24V), or SOLE-
NOID
[BYPASS/CLUTCH]: [NOT PRESENT] or [PRESENT]
[DB]: Rudder deadband. If rudder DB is higher than 1.3
° , the boat cannot be con-
trolled correctly. In this case, open the [SEA TRIAL] menu, set [RUDDER DEAD-
BAND] to [MANUAL] then adjust rudder deadband so that no hunting occurs.
[SPD]: Rudder speed. If out of the recommended value for the NAVpilot, a warning
message appears.
[RUDDER DUTY]: PWM (Pulse Width Modulation) duty cycle for control of pump out-
put.
• For solenoid systems, the rudder duty indication is 100% always.
• For reversing motor system, this value should be in a range from 50% to 100% for
optimum performance. If the value is lower than 50%, the pump capacity is over-
sized for the steering cylinder volume. While the system may work well, there is a
chance that the pump will fail to start (stalled pump) when there is a heavy load on
the rudder system in heavy seas or large turns because the average voltage applied
to the pump is too low. If the rudder speed is lower than 3 degrees/s and the rudder
duty is higher than 90%, the pump capacity is undersized for the steering cylinder
volume. While the system may also work well, the NAVpilot control unit may not be
