FAULT FINDING MANUAL
For Self Excited and Separately Excited Generators
SAFETY PRECAUTIONS
Before testing the generating set, read the generating set Installation Manual, and this Fault Finding Manual, and become familiar with it and the equipment.
TESTING "LIVE" EQUIPMENT
It is essential that all test instruments are regularly checked for safety, and any connection leads, probes, orclips, are checked to ensure that they are suitable for the voltage levels being tested. Never attempt to test a "LIVE" generator unless there is another competent person present who can switch off the power supply or shut down the engine in an emergency. Never expose "LIVE" connections unless you have created a safe working area around you. Make sure you have made all other persons in the immediatearea fully aware of what you are doing.
SAFE AND EFFICIENT OPERATION CAN ONLY BE ACHIEVED IF THE EQUIPMENT IS CORRECTLY INSTALLED, OPERATED AND MAINTAINED.
Many accidents occur because of a failure to follow fundamental rules and precautions.
ELECTRICAL SHOCK CAN PERSONAL INJURY OR DEATH.
•
CAUSE
SEVERE
Ensure installation meets all applicable safety and local electrical codes.Have all installations performed by qualified Installation technicians. Do not operate the generator with protective covers, access covers or terminal box covers removed. Disable engine maintenance. starting circuits before carrying out
• • •
Disable closing circuits and/or place warning notices on any circuit breakers normally used for connection to the mains or other generators, to avoidaccidental closure.
Observe all IMPORTANT, CAUTION, WARNING, and DANGER notices, defined as: Important ! Important refers to hazard or unsafe method or practice, which can result in product damage or related equipment damage. Caution ! Caution refers to hazard or unsafe method or practice, which can result in product damage or personal injury.
Warning refers to a hazard or unsafe method orpractice, which CAN result in severe personal injury or possible death.
Danger refers to immediate hazards, which WILL result in severe personal injury or death.
Due to our policy of continuous improvement, details in this manual which were correct at time of printing, may now be due for amendment. Information included must therefore not be regarded as binding.

SECTION 1
RECOMMENDED METERING AND TEST INSTRUMENTS
To successfully carry out the various test procedures suggested in this manual, certain test instruments are essential. The following lists detail the basic requirements in this respect. It should be noted that in addition to theseinstruments a comprehensive kit of tools is also essential. For fault finding purposes this need not include any specialised tools.
