TROUBLESHOOTING PROCEDURES
This work package contains general information for troubleshooting the AVCS (MINI) Audio Feed by user level
qualified personnel. A qualified person is one who is familiar with this manual, the operation of the AVCS (MINI)
and the hazards involved in its operation and maintenance. The work package provides a systematic approach to
locating and correcting malfunction of the AVCS (MINI). Each section is arranged according to the
condition/indication of a problem. The corrective action items have been arranged in order of complexity, with the
simpler actions listed first. Note that troubleshooting causes and actions beyond the scope of operator level
qualified personnel are not included in the WP. If a course of action does not present itself, contact your
supervisor.
The most important step of troubleshooting is to gather as much first-hand information as possible from the
personnel who were present when the problem or failure occurred. Information as to how long the AVCS (MINI)
has been operating, what systems were connected, whether any protective equipment or devices functioned, etc.,
can also help isolate a problem. Note that if in any doubt about how to proceed, contact your supervisor before
taking action.
WARNING
Tools, equipment, clothing and your body must be kept clear of all electrical connections,
while power is applied to the system
Voltage sources, in addition to being an electrical shock hazard, may also potentially
produce serious burns. Care should be exercised when using hand tools around exposed
power connectors. Never let tools bridge two terminals.
If the circuit breaker does not stay in the ON position when energized, DO NOT attempt to
energize repeatedly. This could cause damage to the surge protector or other
components. Instead, investigate and identify the cause of the problem. Correct the
situation before attempting to energize breaker again.
To avoid electrical shock and damage to the equipment, ensure the power cable is
disconnected at the power source before removing or replacing any cables.
