For best efficiency and performance, the least
amount of convection air possible should be
used. Optimal energy efficiency is achieved
when the majority of energy transfer from
heating elements to product occurs through
radiation. Convection air tends to decrease the
overall efficiency of this process, and should
thus only be used when required.
Exhaust and Cooler:
The exhaust and cooler settings are also
contained in each program, such that certain
products may have these fans turned on while
other products may have them turned off. Use of
the exhaust and cooler fans is optional.
Bulb Powers:
The Firefly Curing System has the ability to set
independent bulb powers for every bulb in the
system. These powers are set using the expanded
program options on the main screen (Figure 3)
Figure 3: Bulb Powers Option
Controlling the bulb powers allows for great
flexibility in managing the intensity of heat in
the system. Setting all bulb powers at 100%
ensures maximum intensity heat for maximum
production throughput. Lower power settings
allows for moderate intensity heat for delicate
applications. Varying powers can be set to
optimize specific jobs, such as setting high bulb
powers on the front few bulbs to act as an initial
“bump”, and setting the rest of the bulbs lower to
maintain the cure temperature while minimizing
any possible overshoot.
Generally slower belt speeds require lower bulb
powers, whereas faster belt speeds require higher
bulb powers.
Default Program:
When the Firefly Curing System first powers on,
every belt loads the “Default” program cure
parameters. These parameters may be adjusted at
the main control Kiosk by choosing “Settings”
→
“Default Program” (Figure 4)
Figure 4: Default Program Button
In the Default Program Screen (Figure 5), the
default cure parameters may be adjusted. If
adjustments are made, the “Back” button will
change to “Save”. Press the “Save” button to
save changes, or “Reset” to discard changes.
