Warning

CE Marking of Equipment/Replacement Parts

If the Autohelm equipment under repair, test, calibration, installation or setting to work carries the European CE mark,only parts and components supplied or approved for such use by Raytheon should be used in order to maintain

compliance with the relevant CE requirements.

Incorporation, use or attachment, by any means, of parts or components not supplied for or not approved for such use byRaytheon or, if supplied or approved for use by Raytheon, not properly fitted in accordance with instructions published,

provided or recommended by Raytheon, may cause the equipment to malfunction and, in particular, to become unsafe orto no longer meet the relevant CE requirements. In these circumstances, Raytheon Marine Europe Ltd excludes liability

to the fullest extent permissible in law for any loss or damage including any liability for its contribution to such loss ordamage by its negligent acts or omissions .

Chapter 1. Before DismantlingBefore dismantling the autohelm ST3000 check the phase of the autopilot (IfPCB condition allows) by driving the pilot, in standby mode, with the coursechange keys.

+10 key –10 key

Aft facing actuator Clockwise actuator rotation Anticlockwise actuator rotation

Forward facing actuator Anticlockwise actuator rotation Clockwise actuator rotation

All new spares PCBs are factory set to operate the pilot with the drive unitfacing aft. A replacement PCB for an installation with the drive unit facingforward requires resetting.

To reset the operating sense press the +1° and -1° course keys together for5 seconds.

The unit beeps for 10 seconds to confirm changeover and the display showsthe new setting, either ‘Port’ (actuator sprocket facing forward) or ‘Starb’(actuator sprocket facing aft’).

The autopilot may be calibrated t to suit a particular vessel. Note thecalibration settings and set up the new PCB if required.

If the spares PCB contains software of a higher issue than before then therelevant Operating Supplement must be supplied when the equipment isreturned to the customer.

Note: Replacement PCBs require setting up to ST3000.Refer to Autopilot type selection on page 3 for instructions.

Chapter 2. Special Functions

Display testA display test feature included in ST3000 software checks that the displayassembly has been re-fitted correctly. Display test is switched on bymomentarily pressing the -1° and +10° keys together

The display scrolls all four characters through from 0 to 9 and then displayseach annotation. This sequence continues until either the ‘Standby’ or ‘Auto’key is pressed or the unit is powered down.

Autopilot type selectionThe Autohelm range of cockpit pilots all contain the same software but eachpilot runs a different program. This is contained within the same chip butneeds to be selected as follows:

1. Press the -10° and +1° degree keys until the display shows the pilot typenumber (Approximately 5 seconds)

2. Press the -10° and +1° degree keys again until the display flashes thepilot type number (Approximately 5 seconds)

3. Select the correct pilot type using the +1° and -1° degree keys

4. Save the setting by pressing the -10° and +1° degree keys until thenormal Standby display appears (Approximately 2 seconds)

Note: Changing Autopilot type will clear all calibration settings.

Display of software codeThe software code of the pilot can be displayed as follows:

1. Switch the pilot to standby mode

2. Press the Standby key until the display shows P followed by a number.(Approximately 10 seconds)

The number indicates the version of software fitted, e.g. P 0 6 indicatesVersion 6 software

Calibration lockoutTo stop access to compass linearisation and calibration functions on theST3000 autopilot:

1. Press the -1° and Standby keys for 10 seconds until the displayshowsCAL ON (or CAL OFF)

2. Toggle between CAL ON and CAL OFF using the -1° and +1° keys

3. Store the selected setting by pressing the -1° and Standby keys for 10seconds, when the control head returns to normal operation.

Any attempt to linearise the compass or enter calibration when the lockoutfunction is enabled will result in the display showing Cal Off. In this conditionthe user cannot change any settings.
