Shut-Down; Pid Temperature Controller - Cole Parmer FSB-200 Series Instruction Manual

7. Make sure the exhaust system is plumbed according to our recommendation (see Figure 2 and section
FUME CLEANING).
8. With the exhaust fan on, close the damper so there is no extraction to the bath.
9. Place parts to be cleaned in the basket and lower into the bath. Place the lid on the bath.
10. When smoke and fumes start to come up and around the lid, slowly open the damper just to the point
where they are pulled back into the bath and no longer entering the room, then stop adjusting. This
setting will give good results with minimal heat and sand loss.
11. With your first tool cleaning, start with a smaller number of tools and at a lower temperature. Adjust
the bath set temperature and the number of tools cleaned based on your results and the amount of
time required. It is always a good idea to clean at the lowest possible temperature.
12. After repeated tool cleanings heavier clumps and larger particles should be sieved from the aluminium
oxide.
13. In time, the aluminium oxide may become dense and fluidise poorly at which point it should be
replaced.

SHUT-DOWN

14. The bath air supply and power can be turned off after the temperature has cooled to 200°C/400°F.
15. Alternatively, if used daily, reduce the overnight temperature to 300°C for quicker start up.

PID TEMPERATURE CONTROLLER

The control parameters in the PID temperature controller have been optimized by the factory during
manufacture to give the best results for most applications. Per the image below use the "scroll" button to
navigate to the menu option UNITS for changing display from °C to °F and vice versa.
Two set points can be entered for future recall, press the "scroll" button to access SP1 and SP2. Set a
different set point in each of these. Then "Scroll" to SP.SEL to select either set point SP1 or SP2. The up/
down buttons are used to set the bath set point temperature. If an alarm indicates an overtemperature
condition or thermocouple failure the two buttons labelled as ACK need to be depressed together after
the alarm condition is corrected. If the alarm cannot be cleared please contact Antylia Scientific for
support.
