5.0 Operation
An engine test cell can be a dangerous environment. The dynamometer operator will be exposed to a
number of hazards. These risks are generally associated with the engine under test rather than with the
dynamometer itself and it is thus not possible for SuperFlow to protect the operator against all these
hazards by the design of the dynamometer instrumentation system.
A proper test cell environment eliminates or reduces the risks associated with dynamometer testing as
much as possible. Examples of risks are:
• Excessive noise
•
Risk of fire due to the fuel used
• Risk of burns due to hot engine and exhaust system parts
• Exposure to rotating parts
• Exposure to parts being projected from the engine during operation
• Excessive exhaust gas concentrations
NOTE:
WinDyn is capable of automating test cell controls and integrating certain safety features in these
controls. Contact a SuperFlow Customer Service or Sales representative for more information or
advice.
Emergency Stop
An Emergency Stop switch is mounted near the computer system. Additional emergency stop switches can
be installed in the test cell and control room. In the event of an emergency, press the nearest emergency
stop switch. The emergency stop command will trigger a shutdown of the dynamometer system and return
it to a safe mode.
When the emergency condition has been resolved, turn the switch clockwise to release it, or pull the switch
back out depending on switch type. Then clear E-stop in the NetDyn pop-up window to reset the system. If
the emergency stop condition was not cleared (the push-button released), the condition will remain active.
Electrical Safety
The sensor box and electric throttle control (if
equipped) require 110/230 VAC power. They each
have internal power supplies. Opening, adjusting,
and repairing the power supplies should not be
attempted. Defective power supplies should be
replaced.
Fuses
All SuperFlow equipment is electrically protected by appropriate fuses. If a fuse blows, the cause must be
found and removed. Do not replace fuses with a different type. This may result in a severe hazard for the
user and/or damage to the equipment.
Repairs to the sensor box, console, or throttle
controller should only be performed by a qualified
Customer Service technician.
