SYSTEM ERRORS (THRUSTER COMMAND)
When the TCD 1062 is switched on, it may signal the presence of system errors.
Checksum error fl ash
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 disap-
pears.
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 activating the single thruster for about 5 minutes continuously, the relevant thruster command is interrupted.
In this case, both direction leds will flash. Resetting after this problem occurs automatically after a period of time, calcu-
lated by the TCD 1062, necessary to partially cool the thruster.
MANUAL RESET PROBLEMS
Reset problems of this kind occur shut off and turn on the TCD 1062.
Overload on the command electrical line
This problem is signalled when the TCD 1062 finds a short circuit or overload on the thruster command electrical line. In
the case of this problem, the leds relative to the command electrical line on which the anomaly has been detected and
the enabling leds flash slowly.
Check the wiring of the electrical lines from the TCD 1062 to the thruster and absorption of the contactors installed on
the thruster.
Interruption on the command electrical line
This problem is signalled when the TCD 1062 finds an interruption on the thruster command electrical line. In the case of
this problem, the leds relative to the command electrical line on which the anomaly has been detected and the enabling
leds flash fast.
Check the wiring of the electrical lines from the TCD 1062 to the thruster.
