•
For hydraulic systems ensure there is no
seepage of hydraulic fluid and that the
steering ram moves smoothly.
•
Repeat using the - 10 button to drive the
rudder hardover to the opposite end stop.
Current Limit and Cutout
When the rudder is driven onto end stops drive
will be cut out after a few seconds. This is normal.
Drive will only be restored if the rudder moves
away from the end stop or if drive is required in
the opposite direction.
3.8 Mechanical Test - Stern Drive
(Autopilot
Steering)
It is recommended that the 'Auto Release' facility
is used when the Autohelm mechanical stern drive
actuator is installed. This is selected and tested as
follows:
•
Select 'Auto Release' in calibration mode (see
4.3)
•
Select 'Auto Release '1’ (ON).
•
Exit calibration mode. Manually drive the
steering hardover to starboard.
•
With the vessel's engines running engage
Auto and with repeated presses of the - 10
button drive the steering to the opposite lock
(Port).
•
The autopilot should drive the steering onto
the end stops, sound an alarm whilst
displaying the Release message and then
revert to Standby.
•
Re-engage the autopilot (Auto) and repeat the
above driving the steering hard to starboard
using the + 10 button.
•
The autopilot should again drive onto the
endstop, alarm/display Release and return to
standby.
Note: If the ST7000 sounds the alarm and
displays 'Release' before reaching the opposite
lock carefully check the vessel's steering system
for any stiffness or mechanical jamming.
If the condition persists set the 'Auto Release'
function to "off" and contact the Product Support
Department at Raymarine for further advice.
Warning
•
The 'Auto Release' function should always be
set to "off" if using any drive unit other than a
stern drive actuator.
•
Auto Release is not available in drive level 4.
3.9 Rudder Angle Limit
(All Drive Units)
Having checked the correct functioning of the
drive unit and the appropriate End Stop
Cutout/Auto Release function the programmable
rudder angle unit should be set.
The rudder angle limit sets the maximum angle to
which the autopilot will move the rudder. This
should be set to just less than the vessel's
mechanical limit stop to avoid putting the steering
system under unnecessary load.
Using the rudder angle display record maximum
rudder angle in both directions and set up the
rudder angle limit in calibration mode (see 4.3) to
5 degrees less than the minimum angle recorded.
