OPERATION

NoteIf at any time the TemperatureAdjustment knob is turned ineither direction, the setpoint willchange, even if the Push To SetTemperature button is notdepressed. To view the currentsetpoint temperature, depressthe Push To Set Temperaturebutton.

12

Sensor Break ProtectionThis controller provides sensor break protec-tion in the event the thermocouple opens. If anopen thermocouple condition occurs, the digitaldisplay will indicate 5 degrees or less and thepower to the heating element will be shut off(CYCLE light will extinguish).

OPERATION

13

• For best results of furnace loading, useless than two-thirds of any dimension ofthe chamber. Maintain a 3/4" clearancebetween the load and the sides of thechamber.

• If you are heating a number of smallparts, spread them throughout the mid-dle two thirds of the chamber.

• Keep objects away from thermocouple.

• Raise your load up off the furnace floorwith small pieces of ceramic or a hearthplate to promote even heating.

• Use insulated tongs and mittens whenloading and unloading furnace.

• Always wear safety glasses.

Furnace Loading

CautionDo not overload your furnacechamber or allow the load totouch the thermocouple. If theload is to be heated uniformly, itshould not occupy more thantwo-thirds of any dimension ofthe chamber. Failure to observethese cautions could result indamage to furnace componentsand/or load.

14

Contamination is a major cause of element failure,therefore, when possible, remove the fume formingmaterial before heating (e.g., cleaning cutting oilfrom tool steel).

The resistance wire is high-grade nickel-chromium.Some chemicals, notably sulphur, halogens, andcyanides, attack this wire at high temperatures, soavoid spilling these chemicals in the furnace orheating them any hotter than necessary. Therefractory cement helps to protect the wire, but willnot completely immunize it from damage.

All heating elements must be considered expend-able, and replacement is expected; however, rea-sonable care in their use will greatly extend the ser-vice they will give. As the manufacturer has no con-trol over the use or care of the elements, no specif-ic service guarantee can be made.

Housekeeping is vital to your electric furnace—KEEP IT CLEAN! Run your furnace up to 871°C(1600°F) empty occasionally to burn off the conta-mination that may exist on the insulation and ele-ments. Run for approximately two hours with thedoor slightly open.

Element life is reduced somewhat by repeatedheating and cooling. If the furnace is to be usedagain within a few hours, it is best to keep it at theoperating temperature or at a reduced level suchas 260°C (500°F).

During normal use, the thermocouple in your fur-nace can become oxidized and cause inaccuratereadings; therefore, we suggest that if you regularlyuse your furnace you should change your thermo-couple once every six months to assure the accura-cy of your controller readings.

Clean by wiping the outside case of the unit with adamp cloth and mild soap solution.

Preventive Maintenance

WarningBefore using any cleaning ordecontamination methodexcept those recommendedby Barnstead|Thermolyne,users should check withBarnstead|Thermolyne thatthe proposed method will notdamage the equipment.

WarningDisconnect the furnace frompower supply before clean-ing.

NoteIt is seldom necessary to disconnectthe thermocouple from the controllerif the thermocouple is in good condition.

17

6. Remove the back insulation block byopening the door and gently pushing itout. Support this insulation block whileremoving it, as it is quite soft and easilycrumbled at the edges.

7. Remove bottom cover to obtain accessto terminals.

These steps will expose the heating elementleads and insulating bushings in the bottomplate of the furnace.

8. Cut the element leads between the ele-ment and the terminal block. (There aretwo leads.) The element and hearthplate unit may now be removed bypushing it straight back out of the fur-nace. Use care not to damage thechamber insulation when removing thehearth plate and element as it can bereused if it has not been contaminated.

9. Remove the old element lead wire andpower wires from the terminal block,and save the glass sleeving for re-installation on the new element leads.Sleeving must be replaced if cracked orbrittle!

10. New elements are shipped flat to pro-tect them from damage in shipment,and to save space in storage. Theymust be formed before installation.

11. Place the element on a flat surface withthe smooth (exposed element) side up.Place a board or other straight edgealong one row of notches.

12. Gently bend the element along thestraight edge. The refractory cementwill break along the row of notches.

MAINTENANCE AND SERVICING

NoteThe hearth plate contains noheating coil, and may be savedfor re-installation if it is in goodcondition. The hearth plate isreplaceable independent of theheating element.

18

Make the bend 90°, avoiding exces-sive bending. (The element wires willbe exposed at the corner thus formed.This will not affect its life or perfor-mance.)

13. Bend the other side of the element.

14. Place the hearth plate across the openend of the ‘’U” shaped element.

15. Slide the element and hearth plate unitinto the chamber, pushing it firmlyagainst the hearth collar. Use care notto damage the soft insulation. Removeany crumbs of insulation that may getbetween the unit and the hearth collar.

16. Thread the element leads through theceramic bushings. Bend the leads sothey lie close to the refractory plateand the bottom insulation block. (Theeasiest and safest way to do this is topress the wire flat with a stick or bluntpusher. Do not use a sharp object ornick the wire.)

17. Replace the glass sleeving and bendthe lead 3/4 turn around the terminalscrew. Cut off the excess wire.Replace power wires on top of ele-ment lead wires and tighten screw. Donot cross the wire over itself aroundthe terminal; this makes it difficult tokeep the connection tight and preventsgood electrical contact. If you haveexcess wire, cut it off. Make sure ele-ment lead wires are not touching anyother wires.

18. Replace bottom cover of control unit.


NoteNicking or damaging the ele-ment leads will cause prema-ture element failure.

19

19. Replace the back insulation block andback plate.

20. Examine the thermocouple, and, if it isgood, reinsert it into the chamber. Itshould extend about 1-1/2" into thechamber. Make sure porcelain insula-tor is in place for the thermocouple topass through on the steel back plate.Replace clamp and screw. (Excessivescaling, pitting, or cracks are someindications that the thermocouple mayneed to be replaced.)

21. Replace thermocouple cover.

22. If replacement of back insulation isnecessary, carefully redrill hole forthermocouple, using back cover asguide.

23. Reconnect furnace to power supply.

24. Test operation of furnace.

To Replace Thermocouple1. Set furnace on its top.

2. Remove thermocouple cover.

3. Remove screw and clamp holding thethermocouple, then grasp the thermo-couple at the bend where it enters thechamber and pull it straight back fromthe furnace. Retain porcelain feed-through insulator.

4. Remove bottom cover.


WarningDisconnect the furnace from thepower supply before servicing.

20

5) Disconnect the thermocouple from theterminal block by removing the screwson the terminals. Pull the thermocouplethrough the hole in the furnace baseand discard.

6) Insert the new thermocouple into theback of the furnace until the tip extends1-1/2" into the chamber. Make sure theporcelain insulator extends through thesteel back plate to prevent the leadwires from touching metal.

7) Bend the thermocouple sharply so thatit lies flat along the back of the furnace.

8) Thread the thermocouple through thehole in the base which has a nyloninsulator, replace clamp and screw.

9) Bend the thermocouple sharply towardterminal block.

10) Secure the two yellow wires marked “+”together on the terminal block. Securethe two red wires “-” together on theadjacent terminal. Make sure connec-tions are secure to terminal block.

A polarity test of the thermocouple and leadwire is easily made with the use of a magnet.On chromel alumel thermocouples and leadwire, the non-magnetic wire is positive ( + ) andthe magnetic wire is negative ( - ).

11) Replace bottom plate.

12) Replace thermocouple cover.

13) Reconnect furnace to power supply.

14) Test operation of furnace.


NoteIf the thermocouple touchesmetal, this could short out thesignal, causing the control todisplay room temperature. Thiscould cause the furnace temper-ature to run away, possibly dam-aging furnace components.

NoteIf the furnace temperaturemoves downward, the thermo-couple leads are reversed.
