4.0 - SYSTEM ERRORS
5.0 - SYSTEM PROBLEMS
When the control is switched on, it may signal the presence of system errors.
4.1 - Flash checksum error
If the error is detected, all the LEDs will flash quickly.
In this case, contact an assistance centre or Quick
®
customer service as soon as possible.
System problems are listed below, divided into two categories:
automatic reset problems and manual reset problems.
5.1 - Automatic reset problems
Problems of this type are reset automatically, as soon as the cause that has generated the problem disappears.
Low voltage supply
The signalling occurs only when the control is enabled.
The problem is signalled if the power supply voltage drops 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 presence of this problem the enabling LEDs flash slowly and a sound is emitted when they turn off.
Protection against prolonged motor activity
After about 5 minutes and 40 seconds of continuous (or equivalent) use of the stern or bow thruster, the control of the
(stern or bow) 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 (bow or stern) flash together twith the enabling
LEDs 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 stern or bow 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 relevant section (stern or bow).
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 can be used again for 5 minutes and 40 seconds.
5.2 - Manual reset problems
The control will signal, with a certain number of flashes of the enabling LEDs, the presence of any manual reset problems.
Together with the flashes a short sound can be heard.
