Preface
The Alphatron AlphaPilot MFM system is a type approved heading control system, designed to fit
vessels of any size, including high speed crafts.
The Mode Switch 3 Pos is part of the AlphaPilot MFM system and is used to select the steering
control mode.
Redundancy is achieved by using a 2 separate CAN busses (1 for manual FU steering and 1 for
automatic steering) and hardwired contacts (from the NFU Tiller directly to the steering control
valves).
Switching from automatic steering to manual FU steering (and vice versa) is only possible by changing
the position of the Mode Switch.
•Thoroughly read this operation manual before operating the equipment.
•We recommend keeping this manual nearby the equipment to ensure ready access to it.

8 | Introduction
Introduction
The Mode Switch 3 Pos is part of the AlphaPilot MFM system and is used to select the steering
control mode. The Mode Switch 3 Pos is typically used in combination with an AlphaPilot MFM
control unit.
The Mode Switch 3 Pos has 1 rotary switch knob and 3 buttons:
-The alarm speaker button will illuminate when there is an alarm. The button is used to mute
the speakers of the Mode Switch 3 Pos and interconnected modules.
-Buttons DIM - and DIM + are used to control the brightness level of the Mode Switch 3 Pos
and interconnected modules.
-The rotary switch knob is used to select the steering control mode.

Switching control mode
The rotary switch knob is used to select the steering control mode NFU, MAN or AUTO.
In case of an emergency, always switch the Mode Switch 3 Pos to the position NFU!
NFU mode
Control mode NFU is for emergency steering.
This mode is sometimes called ‘EMERGENCY NFU’ or ‘NFU DIRECT’. In this mode, the NFU Tiller is
hardwired to the steering gear control valves. Manual steering or automatic steering control is not
allowed when the Mode Switch is in position NFU.
Procedure:
Switch to position NFU to enable NFU control. The control mode indicator NFU will illuminate,
meaning that this mode is enabled (see Figure 2).

Figure 4: AUTO mode
Figure 3: MAN mode

10 | Switching control mode
MAN mode
Control mode MAN is for manual FU steering.
Procedure:
Before switching to position MAN, make sure that the Handwheel, or FU Tiller at conning position
is in a neutral position!
Switch to position MAN to enable manual FU steering. The control mode indicator MAN will
illuminate, meaning that this mode is enabled (see Figure 3 on page 9). When switched to position
MAN, the Handwheel is selected by default, if applicable. If a Handwheel is not available, the FU
Tiller at conning position is selected by default. While the Mode Switch is in position MAN, it is
possible to handover control to other steering modules (e.g. Handwheel or FU Tiller).
In case of an emergency, always switch the Mode Switch 3 Pos to the position NFU!
AUTO mode
Control mode AUTO is for automatic steering.
Procedure:
Switch to position AUTO to enable automatic steering. The control mode indicator AUTO will
illuminate, meaning that this mode is enabled (see Figure 4 on page 9). When switched to position
AUTO, the AlphaPilot MFM control unit at conning position is selected by default. While the Mode
Switch is in position AUTO, it is possible to handover control to other steering modules (e.g. FU Tiller
ROT or AlphaPilot MFM control unit).
In case of an emergency, always switch the Mode Switch 3 Pos to the position NFU!
