Dead man's switch:
The supporting loop of the dead man's switch at the hand-held remote control is to be looped around the
user's wrist during operation of the hand-held remote control. In case of loss of the hand-held remote con­
trol the pin fixed at the supporting loop will be torn out off the hand-held remote control so that the vessel's
propulsion will be turned off. In this way an uncontrolled manoeuvring of the vessel is avoided.
The dead man's switch has a function in active as well as passive mode of the hand-held remote
control!

By tearing off the dead man's switch the engines are set down to idle speed and the gears
are shifted into neutral position. This state will be signalled by lighting up of the two alarm
LEDs and bleeping of the buzzer.
In order to re-obtain command the following steps have to be carried out:
1 Acknowledge error message by means of command push-button (consequence: buzzer
off).
2 Plug dead man's switch back into the designated bushing.
3 Move both control head levers to neutral position.
Subsequently, the alarm LEDs will cease to be lighted and the hand-held remote control
has command again.

When requesting command without a dead man's switch being provided the following error
messages will occur:
1 Both alarm LEDs will be lighted.
2. The buzzer sounds.
3 The two command LEDs will be slowly flashing.
Only after plugging the dead man's switch back into the designated bushing command can
be taken over.

Pressing a thruster button switches on the corresponding thruster. Releasing the button terminates the
function.
.
All relay outputs are available at the same time.If, for example, the push-buttons for starboard and port­
side bow thrusterare activated at the same time, accordingly both contacts will be closed.
Anchor winch push-buttons:
The anchor winch buttons are used to raise and lower the anchor. The operation is terminated when the
button is released.
.
All relay outputs are available at the same time. If, for example, the push-buttons for anchor winch up­
wards and downwards are operated at the same time, accordingly both contacts will be closed.
Safety stop push-button:
Caution:
The safety stop push-button is also effective in case of an inactive hand-held remote control!
A safety stop button is available for both the port and starboard sides (see Chapter 1, page 26).
The engine is stopped immediately by actuating the safety stop button.
