FUSE
FUSE1
For the power supply circuit of the control unit.
FUSE2
For the Hoist motor
FUSE3
For the hoist circuit
When the fuse 1 blows, the Hoist raised the soundome, but does not lower it.
When the fuse 2 and 3 blow, the Hoist neither raises nor lowers the soundome.
Barnacles or oysters that adhere to the soundome will cause the soundome trouble.
Therefore remove them whenever they are found.
Also remove them when the ropes etc. got twisted round the soundome.
When overloaded, other than the fuse 2 the protect circuit in the monitor unit becomes active
to protect the circuits or the hoist motor.
The circuit returns automatically after it is cooled down. For that the power should be kept
OFF for a while.
Exchange the fuse 2 if it blows.
Disconnect the power when the Hoist could not raise or lower the soundome.
Otherwise this could damage the motors or Main PCB in Hull Unit.
-8-
The hoist does not raise or lower the soundome.
The hoist stops raising or lowering the soundome on the way.
Are the fuses 1, 2 and 3 all OK?
Is the LED of the main board in the hull unit lit?
Is 8 Volt present in the line at No.3 of J12 on the
main board?
Replace the fuses.
Cut the breaker of your ship.
Remove the connector of the hoist motor.
Manually shift the hoist halfway down.
Turn on the breaker of your ship
.
Is the voltage normal at the point between
No.1 and No.2 of J10 on the main board of
the hull unit?
Check 8Vcircuit
And repair.
Replace the Hoist Motor
Is the Limit Switch OK?
Main PCB in Hull Unit portion
Replace the Limit Switch.
