LED LA STATUS (BI-COLOUR)
LED POWER (GREEN)
LED STATUS DESCRIPTION
OFF Board not powered
SLOW FLASHING Powered board but disabled control
FAST FLASHING Powered board and actuator’s manual movement mode on
ON WITH SHORT SWITCHING OFF Powered board but disabled control and active link with the CAN control station
ON Powered board and enabled control (TCD or CAN station).
LED COLOUR LED STATUS DESCRIPTION
- OFF With powered board, actuator’s manual movement mode on and limit switch anomaly present
RED ON Retractable thruster closed (LSC limit switch enabled)
GREEN ON Retractable thruster open (LSO limit switch enabled)
ORANGE ON Retractable thruster neither open nor closed (LSC and LSO limit switches disabled)
ORANGE FLASHING
Retractable thruster neither open nor closed (LSC and LSO limit switches disabled) and linear actuator
moving.
7.0 - Notification signs
At the end of the cyclical flashing sequence, the “ERROR” LED remains off for a short period.
LED ERROR (RED)
NUMBER OF
FLASHING
DESCRIPTION
NOTHING No anomaly present.
1
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 the mechanism, by the vessel navigating at sustained speed, or by me-
chanical problems of the retractable and relative hatch.
2
Open fuse.
A current absorption exceeding 10A has occurred. The problem can arise from a short circuit or 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.
3
Anomalous limit switch’s condition.
The problem is signalled when the board detects an anomaly on the limit switches (both activated). Verify the wiring of the power
lines from the board to the limit switches and their functionality.
4
Actuator command line interruption.
The problem is signalled when the board detects an interruption in the command power lines of the actuator. Verify the wiring of
the power lines from the board to the actuator.
5
Timeout of actuator’s movement intervention.
The problem is signalled when the movement command given to the actuator is not executed within 15 seconds.
6
Mistaken dip-switch setting.
The problem is signalled when the dip-switch positions have not been set correctly.
7
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 thresh-
old. The problem can be caused by a foreign body that entered the mechanism, by the vessel navigating at sustained speed, or by
mechanical problems of the retractable thruster and relative hatch.
8
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.
Verify the wiring on the power lines from the board to the propeller and the absorption of the motor reversing contactor unit in-
stalled on the propeller.
9
Activation of the thermal protection on the motor
The problem is notified in case the thermal protection on the motor is tripped.
Wait for the thruster to cool off.
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.
Verify the wiring of the power lines from the board to the motor reversing contactor unit installed on the propeller.
