Safety Procedures
The WinDyn instrumentation system controls the engine and the dynamometer. As a result, there is a
possibility that a certain function or equipment is activated at a time when this creates a hazard to a person
in the area. Avoid such hazards by strictly enforcing the following policies:
• Only authorized personnel, trained in the operation of the complete test system, should have access to
the dynamometer area.
• Never allow anyone in the test cell during a test. Access during warm-up periods and when the engine
is idling is permissible.
• Power OFF the system during periods when the dynamometer is not in use.
• Ensure good visibility of the complete test cell area from the operator position.
• Ensure circuit breakers are easily accessible and have the proper rating.
• Ensure fuel and water shut-o valves are easily accessible.
• Ensure re extinguishers are available and certied.
• Allow only authorized personnel to perform maintenance and repairs on electrical and mechanical
equipment.
• Always turn power OFF to the system before plugging in cables and sensors to the Data Acquisition
sensor box.
• Always turn power OFF to the system when changing engines.
