B2 TROUBLESHOOTING QUESTIONS
Prior to lifting a tool or stepping on board the vessel,
many problems can be resolved by asking the customer
the following basic questions:
A) Is the System installed on a Single, Twin or Mul-
tiple Screw vessel?
• If the System is installed on a Single Screw vessel, this
question does not have much value in narrowing down the
source of the problem.
• If the System is installed on a Twin or more Screw applica-
tion, this question is quite useful, if you ask the following
question.
1. Does the problem or symptom occur on the Port, Starboard
or both sides?
•
If the problem or symptom occurs on one side only, you have
effectively eliminated 50% of the possible causes. For exam-
ple, the symptom only occurs on the Port side. All of the com-
ponents on the Starboard side have been eliminated as
potential causes.
B) What is the Part Number and Serial Number of
the Processor?
Whenever the factory is called for technical assistance, the part
number and serial number will be required. These numbers pro-
vide the Service Technician information about the operating
characteristics of the Processor. The numbers are located on the
Processor’s front cover.
C) How many Remote Stations are there?
• If only one Remote Station is present, not much will be gained
by asking this question. However, if more than one Remote
Station is being used, command should be taken from one of
the other Stations to see if the problem occurs from another
Station.
• If the problem occurs from more than one Remote Station, the
odds are that the Control Heads are not the cause of the trou-
ble.
• If the problem occurs at one Remote Station only, there is a
greater chance of the Control Head or the Control Head Har-
ness of being the cause.
D) Are any tones generated when the problem
occurs?
The tones are used to bring the operator’s attention to a possible
condition or problem.
The following basic tones can be produced on all Systems:
Slow Repetitive Tone
