DESCRIPTION
FLASHING
No anomaly present.
NONE
High absorption of the actuator during ascent (retractable thruster closing)
Signalling occurs after the system has attempted three ascents in the presence of mechanical
friction exceeding the set threshold. The problem can be caused by a foreign body that entered
1
the mechanism, by the vessel navigating at sustained speed, or by mechanical problems of the
retractable and relative hatch.
Open fuse.
A current absorption exceeding 10A has occurred. The problem can arise from a short circuit or
2
an overload on the actuator power line. Verify the wiring of the power lines from the board to
the actuator or the absorption of the actuator itself.
Anomalous limit switch's condition.
The problem is signalled when the board detects an anomaly on the limit switches (both ac-
3
tivated). Verify the wiring of the power lines from the board to the limit switches and their
functionality.
Actuator command line interruption:
The problem is signalled when the board detects an interruption in the command power lines of
4
the actuator. Verify the wiring of the power lines from the board to the actuator.
Timeout of actuator's movement intervention.
The problem is signalled when the movement command given to the actuator is not executed
5
within 15 seconds.
Mistaken dip-switch setting.
6
The problem is signalled when the dip-switch positions have not been set correctly.
High absorption of the actuator during descent (retractable thruster opening).
Signalling occurs after the system has attempted three descents in the presence of mechanical
friction exceeding the set threshold. The problem can be caused by a foreign body that entered
7
the mechanism, by the vessel navigating at sustained speed, or by mechanical problems of the
retractable thruster and relative hatch.
High absorption on motor reversing contactor unit control's output.
The problem is signalled when the board detects a short circuit or an overload on the electric
control line of the propeller.
8
Verify the wiring on the power lines from the board to the propeller and the absorption of the
motor reversing contactor unit installed on the propeller.
Interrupted connection on the motor reversing contactor unit control's output.
The problem is signalled when the board detects an interruption on the electric control line of
the propeller.
9
Verify the wiring of the power lines from the board to the motor reversing contactor unit in-
stalled on the propeller.
At the end of the cyclical flashing sequence, the "ERROR" LED remains off for a short period.
