SYSTEM ERRORS AND PROBLEMS
EN
SYSTEM ERRORS
When the control panel 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
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 disap-
pears.
Insufficient voltage supply
The signalling occurs only when the control is enabled.
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 power or the electrical circuit.
In the presence of this problem the enablement LEDs slowly flash with a sound, when they are switched off.
Pressing opposite buttons (TCD 2022)
If both direction buttons are pressed by mistake, the direction Leds flash and the command to the thruster is interrupted.
As soon as the direction buttons are released the Leds go off and the control panel is ready for new operations.
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 cooling
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 minutes
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:
