Sensor Break ProtectionThis controller provides sensor break protection inthe event the thermocouple opens. If an open ther-mocouple condition occurs, the digital display willblink “S.br” and the power to the heating elementwill be shut OFF (Cycle light will extinguish).

Over-Temperature Protection(OTP)The OTP will be in effect during any alarm condi-tion when the temperature of the furnace has devi-ated beyond the limit. The “Deviation High” alarm isthe only alarm value which can be changed. Tochange it, press the SCROLL button until “IdHi”appears on the display. Press the UP or DOWNbutton to select the OTP value you desire. We rec-ommend a value of 20° above your working tem-perature to provide protection for your workload.

TuningThis controller incorporates a self-tuning featurewhich determines the optimum control parametersfor the best temperature accuracy with your loadand setpoint. Use this feature the first time you useyour furnace and each time you change either yoursetpoint or the type of load you are heating.Barnstead|Thermolyne recommends you use thisfeature to provide the best temperature accuracythe controller can attain. To use the tuning feature:

1. Adjust the setpoint to your desired value.

2. Press the PAGE button until display reads,“Atun.”

NoteFurnace must be at ambient temperature before starting a tune.

• 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.

17

Preventive Maintenance

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

WarningDisconnect the furnace frompower supply before clean-ing.

WarningOpening the door for anextended period of time willcause the painted surfacesabove the door to be discol-ored or burnt.

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. See warning.

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.

2. Remove screw and clamp holding ther-mocouple, then grasp the thermocoupleat the bend where it enters the furnacechamber and pull straight back. Retainporcelain insulator.

3. When the thermocouple tip is clear of thefurnace back, bend it out of the way.

4. Remove the screws holding the steelback plate to the case.

5. Remove the steel back plate.

20

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.

6. Remove the back insulation block by open-ing the door and gently pushing it out.Support this insulation block while removingit, as it is quite soft and easily crumbled atthe edges.

7. Remove bottom cover to obtain access toterminals.

These steps will expose the heating element leadsand insulating bushings in the bottom plate of thefurnace.

8. Cut the element leads between the elementand the terminal block. (There are twoleads.) The element and hearth plate unitmay now be removed by pushing it straightback out of the furnace. Use care not todamage the chamber insulation whenremoving the hearth plate and element as itcan be reused if it has not been contaminat-ed.

9. Remove the old element lead wire andpower wires from the terminal block, andsave the sleeving for re-installation on thenew element leads. Sleeving must bereplaced if cracked or brittle!

10. New elements are shipped flat to protectthem from damage in shipment, and to savespace in storage. They must be formedbefore installation.

11. Place the element on a flat surface with therough side up. Place a board or otherstraight edge along one row of notches.

12. Gently bend the element along the straightedge. The refractory cement will breakalong the row of notches.

21


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

Make the bend 90°, avoiding excessive bend-ing. (The element wires will be exposed at thecorner thus formed. This will not affect its lifeor performance.)

13. Bend the other side of the element.

14. Place the hearth plate across the open end ofthe ‘’U” shaped element.

15. Slide the element and hearth plate unit intothe chamber, pushing it firmly against thehearth collar. Use care not to damage the softinsulation. Remove any crumbs of insulationthat may get between the unit and the hearthcollar.

16. Thread the element leads through the ceram-ic bushings. Bend the leads so they lie closeto the refractory plate and the bottom insula-tion block. (The easiest and safest way to dothis is to press the wire flat with a stick orblunt pusher. Do not use a sharp object ornick the wire.)

17. Replace the sleeving and bend the lead 3/4turn around the terminal screw. Cut off theexcess wire. Replace power wires on top ofelement lead wires and tighten screw. Do notcross the wire over itself around the terminal;this makes it difficult to keep the connectiontight and prevents good electrical contact. Ifyou have excess wire, cut it off. Make sureelement lead wires are not touching any otherwires.

18. Replace the back insulation block and backplate.

19. Examine the thermocouple, and, if it is good,reinsert it into the chamber. It should extend

22


WarningDisconnect the furnace from thepower supply before servicing.

about 1-1/2" into the chamber. Make sureporcelain insulator is in place for the ther-mocouple to pass through on the steelback plate. Replace clamp and screw.(Excessive scaling, pitting, or cracks aresome indications that the thermocouplemay need to be replaced.)

20. Replace bottom cover of control unit.

21. Replace thermocouple cover.

22. If replacement of back insulation is neces-sary, carefully redrill hole for thermocou-ple, using back cover as guide.

23. Reconnect furnace to power supply.

24. Test operation of furnace.

To Replace Thermocouple1. Set furnace on its top.

2. Remove thermocouple cover. (If equipped.)

3. Remove screw and clamp holding the ther-mocouple, then grasp the thermocouple atthe bend where it enters the chamber andpull it straight back from the furnace. Retainporcelain insulator.

4. Remove bottom cover.

5. Disconnect the thermocouple from the ter-minal block by removing the screws on theterminals. Pull the thermocouple throughthe hole in the furnace base and discard.

6. Insert the new thermocouple into the backof the furnace chamber. Make sure theporcelain insulator extends through thesteel back plate to prevent the lead wiresfrom touching metal.

NoteIf the thermocouple touches metal,this could short out the signal,causing the control to display roomtemperature. This could cause thefurnace temperature to run away,possibly damaging furnace compo-nents.

23


NoteIf the control temperature displaymoves downward, the thermo-couple leads are reversed.

7. Thread the thermocouple through the holein the base which has a nylon insulator,replace clamp and screw.

8. Bend the thermocouple sharply toward ter-minal block.

9. Secure the two yellow wires marked “+”together on the terminal block. Secure thetwo red wires “-” together on the adjacentterminal. Make sure connections are secureto terminal block.

A polarity test of the thermocouple and lead wire iseasily made with the use of a magnet. On chromelalumel thermocouples and lead wire, the non-mag-netic wire is positive ( + ) and the magnetic wire isnegative ( - ).
