5 Commissioning the Autopilot
4. For hydraulic systems, make sure there is no seepage of hydraulic
fluid and that the steering ram moves smoothly.
CAUTION:
If the installation is a non Raymarine Constant Running Pump,
firstly check that the system includes a pressure relief valve.
Failure to do this could cause damage to the steering system.
5. Repeat driving the rudder hardover to the opposite end stop.
Current limit and cut-out
When the rudder is driven onto the end stops the power to the 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.
Mechanical test (sterndrives)
It is recommended that the Auto Release facility is used when a
Raymarine mechanical sterndrive unit is installed. This is
automatically selected when the vessel type in calibration is set to 4.
1. Manually drive the steering hard-over to starboard.
2. With the boat’s engines running, engage power steer and drive the
steering to the opposite lock (Port) using the course change knob.
3. The autopilot should drive the steering onto the end stops, sound
an alarm while displaying the
RELEASE message and then revert to
Standby mode.
4. Re-engage power steer and repeat driving the steering hard to
starboard using the course change knob.
5. The autopilot should again drive onto the end stop, alarm/display
RELEASE and return to standby.
Note: If the unit sounds the alarm and displays
RELEASE before
reaching the opposite lock, carefully check the boat’s steering system
for any stiffness or mechanical jamming.
If the condition persists, set the Auto Release function to “off” (0) in
calibration and contact the Technical Services Department at
Raymarine for further advice.
Note: The Auto Release function should always be set to “off” (0) in
calibration if using any drive unit other than a sterndrive unit.
