The following test procedure covers the 2 items included in the Qualitative Failure Analysis; 1)
Control Head Potentiometer failure, and 2) Loss of power supply.
1)
Failure: Control Head Potentiometer failure
.
a)
Results: The Processor will shift to Neutral (if needed) and throttle will go to Idle, (if
needed).
b)
Test Procedure
i)
Turn power on to both Port and Starboard Processors. Take command at a Control
Head.
ii)
Move the Port and Starboard Control Head levers to approximately ½ Ahead.
iii)
Locate the green wire coming from the Port Control Head in command, connecting to
pin 6 of the respective terminal block on the ClearCommand 9000 Series circuit board.
Disconnect it from the ClearCommand 9000 Series circuit board.
(1)
The Port Processor will shift to Neutral and throttle will go to Idle.
(2)
The Port Control Head will give an alarm tone indicating a faulty potentiometer.
iv)
Move the Port and Starboard Control Head levers back to Neutral. Reconnect the
green wire.
v)
Repeat for Starboard side.
2)
Failure: Power failure to
ClearCommand 9000 Series
(A power failure to the ClearCommand 9000 Series circuit board will have the same
results as a failed microprocessor)
a)
Results
i)
Throttle signal to Idle and clutch servo will remain at last commanded position.
ii)
LED at Control Heads will not be lit.
iii)
Opposite engine still under power has full control.
b)
Test Procedure.
i)
Turn power on to both Port and Starboard Processors. Take command at a Control
Head.
ii)
Move the Port and Starboard Control Head levers to approximately ½ Ahead.
iii)
Turn power off to the Port side only.
(1)
Port side will go to Idle and clutch servo will remain at last commanded position.
(2)
LED on the Port side of the Control Head in command will go off.
(3)
The Port Control Head will no longer have command of the engine and gear.
(4)
The Starboard Control Head will still have full command of the Starboard engine
and gear.
iv)
Turn power on to the Port Processor. Take command of the Port side.
(1)
The Port Control Head will operate as usual-(Non-volatile memory)
v)
Repeat test for Starboard Processor.
