SYSTEM ERRORS AND PROBLEMS
SYSTEM ERRORS (THRUSTER COMMAND)
When the TCD 1062 is switched on, it may signal the presence of system errors.
Checksum error flash
If the error is detected, all the leds will flash quickly.
In this case an assistance point or the Quick
®
customer service must be contacted as soon as possible.
SYSTEM PROBLEMS (THRUSTER COMMAND)
System problems are listed below, divided into two categories:
automatic reset problems and manual reset problems.
AUTOMATIC RESET PROBLEMS
Resetting after problems of this type occurs automatically, as soon as the cause that has generated the problem disappears.
Low voltage supply
The problem is signalled if the power supply voltage descends below 10.5Vdc for more than one second. Resetting after
this problem occurs if the power supply voltage exceeds the threshold of 11.5Vdc for more than one second.
Check the charge state of the battery group that supplies is derived or the electrical circuit.
In the case of this problem, the enabling leds go off for a moment.
Protection against prolonged motor activity
After about 5 minutes and 40 seconds (or equivalent) of continuous use of the thruster, the control of the thruster is disabled
for 20 minutes, time needed for the partial cooling of the relevant thruster (total cooling usually takes about 40 minutes).
Whenever this problem occurs, the relevant green and red direction leds flash together to the enablement LED with an
intermittent sound alarm (the duration of this sound alarm is 10 seconds per minute).
The system saves this partial cooling time elapsed for the thruster; if the system is accidentally turned off (power cut off
to the relevant TCD unit) before 20 minutes elapse, upon re-starting, you will have to wait for the remaining partial cool-
ing time before using the control of the thruster.
Once this partial cooling time is over, you will be able to use the control of the (stern or bow) thruster again for a period
of time calculated by the system and proportional to the time the thruster was not used (which may be less than 5 min-
utes and 40 seconds).
Once the total cooling time is over, the thruster may be used again for 5 minutes and 40 seconds.
MANUAL RESET PROBLEMS
The control will signal, with a certain number of flashes of the enablement LEDs, the presence of any manual reset prob-
lems. Together with the flashes a short sound can be heard.
What follows is the correlation table between the flashes and the manual reset problems:
The resetting of this class of problems occurs, once the cause that has generated them has been removed, by switching off and
switching back on the remote control.
When problems 3, 4, 5 are present, it may be necessary to turn off and turn back on the external devices that signalled the pro
-
blem. Refer to their installation and use manual.

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 propeller. Check the wiring of the electrical line of the remote control to the
propeller and the absorption of the remote control switches installed on the propeller.
2
Interruption on the
command electrical line
The problem is signalled when the control detects an interruption on the command electrical line of
the propeller.
Check the wiring of the electrical line of the remote control to the propeller.
3
Problem present on the
BTR* propeller.
The control system of the BTR propeller 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 remote control switch of the propeller.
Refer to the TMS use and maintenance manual.
* If installed.
