The controller, heating mantle, and thermocouple form a closed loop feedback system. When the controller is
connected to a heating mantle, the feedback loop should not be broken at any point
3.6 Do’s and Don’ts When Using Your Controller
Do’s Don’ts
Always use a ask and heating mantle that are the proper size
for the volume being heated.
Use the smallest heating mantle and ask that can handle the
reaction. By doing this, it is made sure that the heating mantle’s
heating capacity roughly matches the volume being heated.
Additionally, it enables the system to dissipate surplus heat to
reduce temperature overshoots.
Never remove the thermocouple from the solution while the
controller is still turned on.
The thermocouple should always be immersed properly in the
solution.
The thermocouple’s rst 1/4” should be inserted completely
into the solution. Use a thermocouple with Teon coating while
heating a corrosive combination.
Controlling an exothermic process using the controller is never
a good idea. There is no cooling capability in the controller. If an
exotherm is anticipated, it has to be regulated dierently.
Avoid exposing the controller to corrosive gases and liquids.
The environment under a research hood is detrimental to all
electronics. Keep the controller away from corrosive vapors by
positioning it outside the hood.
NOTE: Your controller has been tuned to match the capacity of the heating mantle attached to your purchased
system. The power ratings and capacities of heating mantles may vary. In any event, that you may want
to increase or decrease the size of your heating mantle, Ecodyst Scientic, Inc. recommends that you rst
communicate with our service team for technical and engineering advice before adapting the controller to any
new heating mantle other than the one included in your original purchase.
Instead of autotuning the controller with your new heating mantle of choice, Ecodyst Scientic, Inc. advises that the
controller be manually adjusted by following the steps below if you wish to use your controller with other heating
mantles after it has been set for a dierent size or style of the heating mantle.
