Safety measures

Warning indications

The following warning indications are used in this manual in the con-
text of safety:
Indicates that great potential danger exists that can lead to serious
injury or death.
Indicates that a potential danger that can lead to injury exists.
Indicates that the usage procedures, actions etc. concerned can re-
sult in serious damage to or destruction of the device. Some CAU-
TION indications also advise that a potential danger exists that can
lead to serious injury or death.
Emphasises important procedures, circumstances etc.
Symbols
Indicates that the relevant procedure must be carried out.
Indicates that a particular action is forbidden.
When using the bow thruster watch out for swimmers or light
boats which could be in the near vicinity of the bow thruster tun-
nel openings.
Pass on the safety instructions to others using the bow thruster.
General rules and laws with regard to safety and accident-prevention
also need to be applied.
• Never touch the moving ends of the bow thruster whilst in opera-
tion.
• Never touch hot parts of the bow thruster and never place flam-
mable materials in the vicinity of the bow thruster.
• Always stop the bow thruster before checking components or ad-
justing the bow thruster.
• Always disconnect the battery terminals during maintenance
work.
• Ensure maintenance work is safe by only using tools suitable for
the purpose.
• Always deactivate the main switch when the bow thruster is not
in use for long periods.

2 Introduction
This manual gives guidelines for the use of the VETUS 'BOW PRO' bow
thrusters.
The bow or stern thruster system consists of the following basic com-
ponents:
- Side thruster
- Tunnel
- Energy storage
- Energy supply
- Operation
Please consult the user manuals of all components before
putting the complete system into operation.
The 'BOW PRO' bow thrusters have the following features:
• The thrust is continuously variable.
• The runtime is mainly limited by the capacity of the installed bat-
teries.
• The thrust delivered is, within certain limits, not dependent on the
battery voltage.
- With a decreasing battery voltage, the controller ensures that
the thrust will be maintained (APB, Active Power Balancing).
- However, the current will increase with a decreasing battery
voltage. If the current goes higher than is desirable, the deliv-
ered power is reduced (ACC, Automatic Current Control).
- When the batteries are discharged such that the voltage has
dropped to 10,5 Volts, with a 12 Volt system (21 V at 24 V), the
power supplied is reduced (AVC, Active Voltage Control)
- If the discharge of the batteries proceeds still further, so if
the voltage has dropped to about 10 volts in a 12 volt system
(about 20 V for 24 V), the bow thruster will stop.
• Overheating of both motor and / or regulator is prevented by de-
creasing the output power after a very long period of continuous
use.
• The thrust only decreases slightly (ATB, Active Temperature Bal-
ancing).
• In the event of a sudden overload of the motor, caused by an ob-
ject in the tunnel, the motor will switch off for safety reasons (ABC,
Active Blockage Control).
• The maintenance is minimal because the motor does not use car-
bon brushes.
Alterations made to the bow thruster by the user will void any li-
ability on the part of the manufacturer for any damages that may
result.
The actual thrust force, as performed by the bow thruster, will give
different results with each individual vessel, depending on the wind-
age, displacement and shape of the underwater section.
The nominal thrust quoted can only be achieved under normal con-
ditions:
• Make sure that the batteries are supplying the correct voltage
during use
