PROBLEM
DESCRIPTION
1
Overload on the
command electrical
line
The problem is signalled when the control detects a short circuit or an overload on
the command electrical line of the thruster. Check the wiring of the electrical line
of the control to the thruster and the absorption of the contactors installed on the
thruster.
2
Interruption on the
command electrical
line
The problem is signalled when the control detects an interruption on the command
electrical line of the thruster.
Check the wiring of the electrical lines of the control to the thruster.
3
Problem present on
the BTR* thruster.
The control system of the BTR thruster has detected a problem.
Refer to the BTR use and maintenance manual.
4
Problem present in
the parallel/series
switch*
The control system of the PSS switch has detected a problem. Refer to the PSS use
and maintenance manual.
5
Problem present on
TMS*
The TMS line switch has detected a problem connected to the control contactor of
the thruster. Refer to the TMS use and maintenance manual.
* If installed.
To distinguish whether the signal concerns the bow or the stern of the boat they will be steadily lit, simultaneously with
the flashing of the enabling LEDs, the green LED and the red LED of the involved part (bow or stern).
Problems of this class are reset, once the cause that has generated them has been removed, by switching the control off
and on again.
When problems 3, 4, 5 are present, it may be necessary to turn off and on again the external devices that signalled the
problem. Refer to their installation and use manual.
5.4 - “Freezing” manual reset problems
Whenever a manual reset problem occurs on the bow or the stern, you can “freeze” the problem in the involved area and
enable again the control so that you can operate in the (bow or stern) area that is not affected by the problem.
ATTENTION:
although the problem is “frozen”, it is always present and has to be solved soon.
ATTENTION:
use the problem “freezing” procedure only if truly necessary since boat manoeuvring is limited only to
the bow or stern thruster.
The procedure is described below:
• Press and hold the enabling button until the visual and sound signals of the fault are no longer seen/heard (number
of flashes of enabling LEDs and relative sound). Now the yellow enabling LEDs flash slowly (the control switches to
disabled status).
• Enable the control following the usual procedure. The control is now enabled and you can control exclusively the (bow
or stern) area that is not affected by the problem.
ATTENTION:
boat manoeuvring is limited only to the bow or stern thruster.
ATTENTION:
any signalling of automatic or manual reset problems will refer to the last area enabled.
