temperature rise due to the application’s mark parameters.
Figure A-1 Graph of heat rise based on normalized mark velocity by temperature curve
Example – locate the approximate position of 71 in/sec on the Normalized Marking Velocity axis
and follow this point up to where it intersects Temperature Curve D. Now read across to determine
the T
GRAPH
Temperature Rise in °C. In our example, this value is around 9 °C.
T
GRAPH
Temperature Rise equals ______ °C.
Determine the other Heat Load variables
1 Enter the ambient temperature (in °C) of the location where Flyer is operating.
Note: Be sure to use the maximum air temperature that could be attained in the area where the ma-
chine is installed during the hottest time of the year.
Example – the location where the Flyer head is installed never rises above an ambient temperature
of 86 °F, which converts to a T
AMB
Value of 30 °C.
T
AMB
Value (in °C) is ______ .
2 Determine the duty cycle of the mark. To do this, divide mark cycle time (in seconds) by the number
of seconds between successive ‘start mark’ signals.
