Introduction
This manual give guidelines for operating the Vetus retractable bow
thrusters 'STE... ' .
The quality of installation will determine how reliably the bow thrust-
er performs. Almost all faults can be traced back to errors or impreci-
sion during installation. It is therefore imperative that the steps given
in the installation instructions are followed in full during the installa-
tion process and checked afterwards.
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 wind
catch, displacement and shape of the underwater section.
The nominal thrust quoted can only be achieved under the most fa-
vourable conditions:
• Make sure that the batteries are supplying the correct voltage
during use
• During the installation process the 'Installation instructions for
retractable for bow thrusters', must be followed, specifically con-
cerning:
- Sufficiently large diameter of the battery cables so that voltage
drop is reduced to a minimum.
Following the above recommendations will result in longer life and
better performance of your bow thruster.
• Carry out the recommended maintenance regularly.
• Never allow the bow thruster to operate for a long period; the
maximum length of usage is restricted because of heat release in
the electric motor. After use the motor must be allowed to cool
down.
The maximum continuous length of usage and the thrust as
specified in the technical details are based on the recommend-
ed battery capacities and battery cables.
If significantly larger batteries in combination with very short
battery cables of significantly larger diameter than recom-
mended are used then the thrust will increase. In such cases
the maximum length of usage must be reduced in order to
prevent damage to the motor.

Use
3.1
General
• Switch on the main switch.
After switching on the power supply on all panels the blue and red
LED will flash alternately 3 times.
The system is now 'stand-by' . The panel or both the panels are not
activated.
The thruster will remain retracted.
After switching on any panel the thruster will be automatically de-
ployed.
Do NOT switch in on the panel if the boat speed is more than
1.5 knot (3 km/hour).
3.2
Switching ON a panel
• Press the 'ON/OFF' switch twice.
After the switch is pressed once the LED will flash blue and the buzzer
will sound continuously didididididi..... (. . . . . . .) The 'ON/OFF' switch
must be pressed a second time within 6 seconds.
The buzzer will confirm this with the signal dahdidah (- . -).
Deploying of the thruster will take approx. 6 seconds, during this
time the LED will flash blue.
Once the thruster is fully deployed the LED will be on continuously
blue.
The buzzer will confirm that the panel is ready for use by giving the
signal dahdidah (- . -).
Two panels on one helm station
(one panel for a retractable bow thruster and one panel for a stern
retractable thruster)
• Press twice on the 'ON / OFF' switch on one of the panels.
Both panels are switched on and bow and stern thruster will be de-
ployed.
Consult the installation manual how to configure panels.
3.3
Switching on the other panel (in case of 2 pan-
els)
To take over from one panel to the other the same procedure as
switching on the first panel must be carried out.
Once the second panel is switched on the first one will be switched
off.
The buzzer on the just switched off panel will reply with the signal
didididahdidah ( . . . - . - ).
