Introduction
Intended Use
The Type 6000 Manual, Automatic and Programmable furnaces are general laboratory and heat treating
furnaces. For optimum element life, observe the following temperature ranges. These furnace models are
intended for applications requiring temperatures from 100°C (212°F) to 893°C (1640°F) for continuous
use, or temperatures from 893°C (1640°F) to 1200°C (2192°F) for intermittent use.
(-60) Coal Ashing models continuous temperature range is from 100°C (212°F) to 893°C (1640°F).
Intermittent temperature range is from 893°C (1640°F) to 975°C (1787°F). Continuous use is operating
the furnace for more than 3 hours and intermittent use is operating the furnace for less than 3 hours.
The unit consists of: 1) a heating chamber; 2) a basic automatic control without over temperature
protection OR an automatic proportioning-digital set, digital read control with over temperature protection;
3) a door interlock relay for user safety.
The Type 6000 Programmable furnace is designed to control a programmed temperature profile. The
profile is in the format of ramps and dwell segments. The first ramp, RAMP 1, starts at the initial
measured furnace temperature. This ramp is positive going at a programmed rate until the programmed
level is reached. The setpoint will stay at this level for a period determined by the setting of DWELL 1.
Additional positive or negative going ramps are now initiated starting at the level at the end of DWELL 1.
When the second ramp reaches the second programmed level, the setpoint stays at that level for the
duration of the segment. Depending upon the model ordered, additional ramp and dwell segments may
be added. See specific model number below for total number of program segments.
The Type 6000 Programmable Ashing Furnace (-60) is designed to operate like the programmable type
6000 described above plus the ability to inject and control an inert atmosphere.

5 Barnstead|Thermolyne • 800-553-0039
Principles of Operation
Furnace:
The furnace chamber is heated by four electric resistance heaters which are embedded in a refractory
material. The chamber is insulated with a ceramic fiber insulation. The control is located under the
furnace chamber and is well insulated from the heat generated in the furnace chamber. A door safety
switch removes power to the heating elements whenever the furnace door is opened. The choices of
temperature controllers are as follows:
Temperature Controller: "Basic Automatic":
The basic automatic control provides simple automatic control to one setpoint temperature. A single
digital display will indicate either furnace chamber temperature or setpoint temperature. This controller
does not provide over temperature protection.
Temperature Controller: "Automatic":
This furnace controller consists of a microprocessor based three mode temperature controller having
adjustable over temperature protection and appropriate output switching devices to control the furnace.
Temperature Controller: "Programmable":
This furnace controller consists of a microprocessor based three mode temperature
controller/programmer with adjustable over temperature protection and appropriate output switching
devices to control the furnace.
NOTE
When in the program RUN mode, the programmer/controller serves to provide a
programmed temperature profile as described earlier. When in the AUTOMATIC mode, the
unit serves as a single setpoint automatic temperature controller.

Unpacking
Visually check for any physical damage to the shipping container. Inspect the equipment surfaces that
are adjacent to any damaged area. Open the furnace door and remove packing material from inside the
furnace chamber. Vacuum the chamber prior to use to remove the insulation dust due to shipment.
NOTE
(-60) Models are supplied with two stainless steel trays, handle and porcelain pegs.
Retain the original packaging material if re-shipment is foreseen or required.
NOTE
The Type 6000 furnaces do not come with a power cord because current requirements are
too great to be handled by ordinary power cords and standard wall supply. (F6010, F6010-33
and F6018 are supplied with cord and plug).
Installation
Site Selection
Install furnace on a sturdy surface and allow space for ventilation.
CAUTION
Be sure ambient temperature does not exceed 104°F (40°C). Ambients above this level
may result in damage to the controller.
Allow at least six inches of space between the furnace and any vertical surface. This
permits the heat from furnace case to escape so as not to create a possible fire hazard.
Electrical Connections
1. The electrical specifications are located on the specification plate on the back of the furnace. Consult
Barnstead/Thermolyne if your electrical service is different than those listed on the specification plate.
Prior to connecting your Type 6000 furnace to your electrical supply, be sure the front power switch is
in the OFF position.
WARNING
To avoid electrical shock, this furnace must be installed by a competent, qualified electrician
who insures compatibility among furnace specifications, power source and grounding code
requirements. (Disregard Step 2 if you have Model F6010, F6010-33 or F6018.)
2. Your 6000 furnace may be wired either directly through a conduit system or by using a power cord
and plug which conforms to the National Electrical Codes and electrical code requirements of your
area. The terminal block to be used in wiring is located on the lower rear of the furnace.

10
CAUTION
For supply connections, use 10 AWG or larger wires suitable for at least 90°C. Failure to
observe this caution could result in damage to furnace.
Observe these two warnings before operating your furnace:
WARNING
Do not use in the presence of flammable or combustible materials; fire or explosion may
result. This device contains components which may ignite such material.
“Caution: Hot Surface. Avoid Contact.” To avoid burns, this furnace must not be touched on
the exterior or interior surfaces during use or for a period of time after use.
Basic Automatic Temperature Control Operation
(F6010, F6010-33, F6018)
Power Switch
The On/OFF power switch will illuminate when power is turned ON. Also, the digital display will illuminate.
Cycle Light
The amber cycle light will illuminate whenever the power is being applied to the heating elements. The
cycle light will turn on and off as furnace reaches setpoint.
Door Safety Switch
The door safety switch removes power from the heating elements when the door is opened. Open and
close the door a few times; note that the amber CYCLE light will be out when door is open. This check
must be done when furnace is heating or when cycle light is illuminated. If this condition is not true,
consult the Troubleshooting section before proceeding.
WARNING
To avoid electrical shock, this furnace must have the door switch operating properly.
Digital Readout
The digital readout continuously displays chamber temperature unless the Push To Set Temperature
button is depressed. Then setpoint temperature is displayed.
Push To Set Temperature Button
When this button is depressed, the digital display will indicate setpoint temperature. When the button is
released, the actual chamber temperature is displayed.
Temperature Adjustment Knob
Turning this knob clockwise will increase setpoint temperature. Turning the knob counterclockwise will
decrease temperature.

11 Barnstead|Thermolyne • 800-553-0039
Temperature Controller
This controller provides accurate control at one single temperature setting. To set temperature, simply:
a) Turn Power switch ON.
b) While depressing the Push To Set Temperature button, turn the temperature knob until you reach
the desired setpoint temperature as indicated on digital display.
c) Release the Push To Set Temperature button.
The digital display will now indicate the actual chamber temperature. The furnace will heat to the new
setpoint temperature. The CYCLE light will remain on until the furnace temperature is within 1°C of the
setpoint temperature; then the CYCLE light will turn on and off as the controller maintains the setpoint
temperature.
NOTE
If at any time the Temperature Adjustment knob is turned in either direction, the setpoint
will change, even if the Push To Set Temperature button is not depressed. To view the
current setpoint temperature, depress the Push To Set Temperature button.
Sensor Break Protection
This controller provides sensor break protection in the event the thermocouple opens. If an open
thermocouple condition occurs, the digital display will indicate 5 degrees or less and the power to the
heating element will be shut off (CYCLE light will extinguish).
Automatic Models
(F6020C, F6020C-33, F6020C-60, F6028C, F6028C-60)
NOTE
The temperature control in these models is a single set-point device. By using the "UP" or
"DOWN" buttons a specific temperature can be chosen. The control will cause the furnace
chamber to heat to the chosen temperature and hold it at this temperature until you turn off
the power switch or select another temperature.
Controls and Displays
Power Switch:
Switch power switch to the "ON" position. The CONTROLLER will illuminate when power is on.
Furnace Power Indicator:
The amber furnace power light will illuminate whenever the door is closed. This light will go out only when
the door is open or when there is an over-temperature condition.
Door Safety Switch:
The door safety switch removes power from the heating elements when the door is opened. Open and
close the door a few times, note that the amber furnace power light will go out while the door is open. If
the furnace power light does not go out while the door is open, consult the Troubleshooting section before
proceeding.

12
WARNING
To avoid electrical shock, this furnace must have the door switch connected and operating
properly. If the furnace power light does not go out while the door is open, consult the
Troubleshooting section before proceeding.
Control Buttons
To illuminate the "DOWN" button, "SCROLL" button, and "UP" button, touch anywhere on the front panel.
NOTE
When performing the operations with the controller, remember that if more than eight to ten
seconds elapse before the buttons are used again, the display screen will automatically
switch back to displaying chamber temperature. If this happens, light up the front panel again
and step through each parameter until you reach the point at which the interruption occurred.
The parameter values you adjusted earlier, however, will not be lost or altered. Holding down
on the "SCROLL" button allows longer viewing time.
Digital Readout:
The Digital Readout continuously displays chamber (upper display) and setpoint (lower display)
temperatures unless the "SCROLL" button is depressed.
Startup Display:
When the power switch is turned on, the controller will perform a self-test to make sure controller is
operating properly. (If all four 1's do not light up or fails to go to "8888" contact Thermolyne.)
Adjusting Furnace Setpoint Temperature
To illuminate the "DOWN" button, "SCROLL" button, and "UP" button, touch anywhere on the front panel.
Push the "UP" button or the "DOWN" button to modify the temperature setpoint (lower digital display).
CAUTION
Do not exceed limitations for continuous or intermittent operating temperature shown in
the General Specifications. Exceeding these limits will result in severely reduced heating
element life.
Tuning:
This control incorporates a self tuning feature which determines the optimum control parameters for the
best temperature accuracy. We recommend that you tune the furnace to your specific application to
obtain the best results. Perform the following procedures when you first set up your furnace and each
time you change your load type or operating temperature.
To tune your furnace:
Load your furnace with a load characteristic of those you intend to heat in it.
Set the furnace's setpoint to the temperature you intend to use for your application.
Push the "SCROLL" button until 'tunE" appears. To start the tuning function, push the "UP" button.

13 Barnstead|Thermolyne • 800-553-0039
When the tuning process is started, the lower display will flash 'tunE" along with the furnace temperature
setpoint. During tuning, the temperature setpoint cannot be changed. To change temperature setpoint
'tunE" must be turned "OFF." (To stop the tuning function, push the "DOWN" button.)
NOTE
If the power to furnace is "turned off" or interrupted while in "tuning,"upon returning power to
furnace, the controller display will indicate "LinE FAIL" because sampled data could be
questionable. To restart tuning, refer to "Tuning" procedure.
If the controller cannot maintain temperature setpoint, "tunE FAIL" will appear on display.
First, correct problem responsible for not maintaining the temperature setpoint, then restart
the "tuning" procedure.
Changing Temperature Indication:
Push "SCROLL" button once, "°C" will appear. This indicates temperature measurement. (Contact
Thermolyne if control needs to be changed to °F.)
Setting the High Alarm Temperature (Over Temperature Protection OTP):
Push "SCROLL" button until "AL.SP" (Alarm Setpoint) appears. The lower display should indicate
1100°C.
NOTE
HIAL- HIGH ALARM. (over-temperature protection, OTP)
The controller is fitted with a mechanical relay which is de-energized in the alarm mode. This
relay, when de-energized, removes power from the heating elements. If the primary control
circuit fails, the OTP will control the furnace temperature at the preset value you have
entered. It does not shut off the furnace. but will maintain the chamber temperature at that
value.
Depress either the "UP" or "DOWN" button to select the OTP value you desire. Thermolyne recommends
that you set the value either at the maximum operating temperature of the furnace or a value of 20
degrees above your working temperature if you desire to provide protection for your workload.

F6020C-33-60-70, F6028C-60-70)
Controls and Displays
Digital Readout:
The digital readout continuously displays chamber (upper display) and setpoint (lower display)
temperatures unless the PAR (parameter) button is depressed.
If a program is in either run, Hb or Hold, pressing "PAR" once causes the lower display to indicate the
current segment of the program (r1, d1, r2, d2, or Hb) along with °C or °F. If the program is currently in
either d1 and d2, the value shown below these parameters (d1 and d2) reflects the time remaining in the
segment.
While the program is in run, Hold, or Hb, the set point shown on the bottom display is the current working
set point.
When the controller is in idle, depressing PAR shows each parameter and its current value in turn on the
display. The parameter value can either be modified with the "up" or "down" push buttons or left
unmodified.
See Parameters for a list of the controller parameters in order.
NOTE
In the event of a thermocouple break (open circuit), the numeric display increases rapidly
upscale, then displays "Sn b" (sensor break), and may alternatively flash "HiAL" (high alarm)
and/or dAL (deviation alarm) and the sensor break power value.
A reversed thermocouple connection or incorrect thermocouple will cause the display to read
"ur" (underrange) and the control will maintain the sensor break power output value selected.
NOTE
When performing operations with the controller, if you depress and release either the "PAR,"
scroll "up," or scroll "down" push buttons and more than 6 seconds elapse before the buttons
are used again, the display screen will automatically switch to displaying chamber
temperature. If this happens, you will have to step through each parameter until you reach
the point at which the interruption occurred. The parameter values you adjusted earlier,
however, will not be lost or altered. Holding down on "PAR" allows longer viewing time.
Power Switch: Set power switch to the "ON" position. The CONTROLLER will illuminate when power is
on.
CAUTION
Remember that whenever the power switch is turned "ON," the furnace will begin to heat
at the setpoint temperature that was previously set. This value will remain unchanged for
up to a year without power being applied to the control.
Furnace Power Indicator:

15 Barnstead|Thermolyne • 800-553-0039
The amber furnace power light will illuminate whenever the door is closed. This light will go out only when
the door is open or when there is an over-temperature condition.
The door safety switch removes power from the heating elements when the door is opened. Open and
close the door a few times, note that the amber furnace power light will go out while the door is open. If
the furnace power light does not go out while the door is open, consult the Troubleshooting section before
proceeding.
WARNING
To avoid electrical shock, this furnace must have the door switch connected and operating
properly. If the furnace power light does not go out while the door is open, consult the
Troubleshooting section before proceeding.
NOTE
Pushbutton "A/M" and light "OP2" are inactive and not used.
Parameters
PROG - program options . By pushing up or down buttons, three options can be chosen: run - to start
program; idle - to end program; hold - to hold program until further action.
SP - set point temperature. When running a program, it is the last temperature value attained. Push up
or down button to set.
TUNE - self-tuning feature. Push up or down button to set.
LC - loop count. The number of times the program is repeated. Push up or down button to set.
r1 - ramp rate #1. The rate of heat increase or decrease in °/minute. Push up or down button to set.
L1 - temp level #1. The temp level that r1 will attain. Push up or down button to set.
d1 - dwell (soak) time #1. The amount of time in minutes to hold L1 temp level #1. Push up or down
button to set.
r2 - ramp rate #2. The rate of heat increase or decrease in °C/minute. Push up or down button to set.
L2 - temp level #2. The temperature level r2 will attain. Push up or down button to set.
d2 - dwell (soak) time #2. The amount of time in minutes to hold L2 temperature level #2. Push up or
down button to set.
Hb - "holdback." Automatically places the programmer into "HOLD" if the measured value deviates more
than a specified amount from programmer setpoint. When measured value reenters the holdback band,
the timing for the segment resumes. (Parameter is expressed in °C and only functions when running a
program). Push up or down button to set.
HiAL - high alarm (over temperature protection). Push up or down button to set. Thermolyne
recommends that you set the value either at the maximum operating temperature of the furnace or a
value of 20 degrees above your working temperature if you desire to provide protection for your workload.
NOTE
The controller is fitted with a mechanical relay which is de-energized in the alarm mode. This
relay, when de-energized, removes power from the heating elements. If the primary control
circuit fails, the OTP will control the furnace temperature at the preset value you have
entered. It does not shut off the furnace but will maintain the chamber temperature at that
value.

16
The next three parameters - Proportional Band, Integral and Derivatives - are the three control
parameters of a P.l.D. control system. These parameters will be set when you tune your furnace. (See
Tuning.)
Prop - Proportional Band.
In.t - Integral Time.
dEr.t - Derivative Time.
HPl - High Power Limit (%) This parameter limits the average maximum power that is applied to the
heating elements. Remember that this parameter does not reduce the voltage to the elements. It reduces
the average power to the elements by cycling power on and off.
C/F - Centigrade/Fahrenheit. Choose the desired temperature unit by depressing the "UP" or "DOWN"
pushbutton.
NOTE
All temperature dependent parameters are automatically converted when the temperature
unit (C or F) is changed.
Tuning Your Controller
This programmable control has an automatic tuning feature which installs optimum tuning parameters to
give the best temperature accuracy. No manual loading of tuning parameters is needed. We highly
recommend using this feature to provide the best temperature accuracy the controller can attain. Perform
the following procedures when you first set up your furnace and each time you change your load type,
operating temperature, or program.
To initiate the self tune feature:
Load your furnace with a load characteristic of those you intend to heat in it.
If you will be using the controller as a single Setpoint Controller, set the furnace's setpoint to the
temperature you intend to use for your application.
If you will be running a multi-step program, set the furnace's setpoint to the value of L1 (temp level #1).
Push "PAR" button until TUNE is displayed, then push "UP" or "DOWN" button to turn tune "ON."
During the operation, TUNE flashes in the lower display. Do not make any adjustments to the controller
parameters during this period. The self tuning is finished when TUNE no longer flashes in the lower
display.
Self tuning will calculate values for:
Proportional band - prop
Integral time - Int.t
Derivative time - der.t
• Self tuning cannot be initiated while running a program.
• A power failure will cause the TUNE parameter to revert back to NO. (Reset tune parameter to YES).
• If there are alarm conditions during self tuning, they flash alternately with TUNE.

Operating the Controller
CAUTION
Do not exceed limitations for continuous or intermittent operating temperature shown in
the General Specifications (in furnace manual). Exceeding these limits will result in
severely reduced heating element life.
Single Set Point Operation
The programmable control can be used as a single setpoint control or as a programmable control. To use
as a single set point control simply push up or down buttons to choose a specific temperature. The
control will cause the furnace chamber to heat to the chosen temperature and hold this temperature until
the power switch is set to OFF or another temperature is selected.
a. The setpoint temperature presently set in the control will be read out on the lower display.
b. To change this set point, depress the "UP" or "DOWN" push button until the desired setpoint value is
displayed then release the button.
c. At this point the furnace will begin to heat if the new set point temperature you have chosen is higher
than the present chamber temperature.
Programming Controller
To run a program, first determine your ramp rate, dwell times. and program levels. It is helpful to graph
your program out for ease of loading the program into controller.
A maximum of 2 ramp and 2 dwell segment combinations are available, thus enabling 2 different set point
levels to be achieved. Each ramp is programmed by specifying the temperature level (L1) and the
required ramp rate (r1). The programmer then automatically calculates the time that is required to attain
the temperature level (L1) based on the desired ramp rate (r1). Dwell segments (d1) then can be
attached to each temperature level (L1) to hold that temperature for a specified amount of time.
Make sure the PROG parameter is set to idle (to stop program) when entering program values. (See
Parameters.)
Push "PAR" until "r1" is displayed. Push "UP" or "DOWN" buttons and set ramp rate "r1" (heat increase or
decrease) in °C/minute.
Push "PAR" until "L1" is displayed. Push "UP" or "DOWN" buttons and set temperature level "L1." This is
the target temperature for the first ramp.
Push "PAR" until "d1" is displayed. Push "UP" or "DOWN" buttons and set dwell (soak) time "d1" in
minutes.
Push "PAR" until "r2" is displayed. Push "UP" or "DOWN" buttons and set ramp rate "r2" in C/minutes.
Push "PAR" until "L2" is displayed. Push "UP" or "DOWN" buttons and set temperature level "L2." This is
the target temperature for the second ramp.
Push 'PAR'' until "d2" is displayed. Push "UP" or "DOWN" buttons and set dwell (soak) time "d2" in
minutes.

18
Push "PAR" until "SP" is displayed. Push "UP" or "DOWN" buttons and modify set point temperature.
After "d2" dwell time has expired, thus ending the program, the last temperature level to be attained will
be equal to "SP" temperature. For example, if after your program has been completed, you want the
furnace to cool to ambient, set "SP" to 20. This will be the last temperature level attained.
Push "PAR" until "LC" is displayed. Push "UP" or "DOWN" buttons and set "LC" (loop count - number of
times program is repeated).
Skipping Segments
If you desire to skip a ramp or dwell segment, follow this procedure:
• for a dwell segment, enter a setting of "0" minutes.
• for a ramp segment, enter a high value such as 100°/min. This will cause controller to skip to next
segment as fast as the furnace is capable.
Setting the Holdback Feature
This controller features a holdback (Hb) function to ensure programmed parameter values are adhered
to. Holdback is set in display units (degrees C or F) and represents the allowable excursion of measured
value away from the current set point, either above or below, before the program is forced into hold (clock
stops).
The program will remain in hold until the measured value comes within holdback band (clock starts). This
feature is active the whole time that the program is running. (Holdback functions only while running a
program).
Push PAR until "Hb" is displayed. Select desired holdback setting - a setting of 20° is recommended.
If a running program is forced into holdback, the illuminated dot below the "R" symbol on controller will
flash and the PROG parameter will indicate "Hb." When the program is in "holdback," it effectively
lengthens the time of the program - if the holdback band "Hb" is set too low, the program will never
escape the holdback band, thus the program will never be completed. If you do not want to use the
holdback function, set "Hb" to an extremely large value.
Implementing Programs
When you have finished programming and are ready to run your program, push "PAR" until PROG is
displayed. Pushing the "UP" or "DOWN" buttons, you have three options: "Run" (to start program), "idle"
(to stop program), "hold" (to hold program) - parameter values can be changed when hold is chosen.
Program Execution
When "run" is selected, the program will start from the actual furnace temperature at that point in time.
Also, the dot under "R" on the control will illuminate to indicate the program is running.
NOTE
Notes alert the manual user to pertinent facts and conditions.
Parameter values r1, L1, D1, r2, L2, D2 and LC cannot be adjusted while running a program.
Program Hold

19 Barnstead|Thermolyne • 800-553-0039
To adjust parameters while running a program, you must put control into "Hold." Push "PAR" until "prog"
is displayed. Push "UP" or "DOWN" buttons until Hold is displayed. When the dot underneath "R" on
controller flashes and "Hold" is indicated at the "prog" parameter, the controller is in Hold. Now you are
able to adjust all parameters. To restart the program, set "prog" to "run" again.
Program Idle
To stop program, push "PAR" button until "prog" is displayed. Push "UP" or "DOWN" buttons until "idle" is
displayed. This will terminate program.

Controls and Displays
Digital Readout:
The digital readout continuously displays chamber (upper display) and setpoint (lower display)
temperatures unless the scroll button is depressed.
If the scroll button is depressed and released, the lower display will indicate output power (OP) or setpoint
(SP). This is referred to as the "short scroll." Continued single step action of scroll button will cause lower
display to alternate between setpoint (SP) and output power (OP).
To enter the main scroll list (list of all controller parameters that are accessed through front keyboard), the
scroll button should be held depressed. PR1 (program ramp rate 1) will appear. To progress through the
parameter list, the scroll button must first be released; subsequent single step depression will advance
you through the list. Rapid progression through the parameter list is achieved by holding the scroll button
depressed.
See Parameters for a list of the controller parameters in order.
NOTE
When performing operations with the controller, if you depress and release either the "scroll,"
"up," or "down" push buttons and more than 8 seconds elapse before the buttons are used
again, the display screen will automatically switch back to displaying setpoint temperature. If
this happens, you will have to step through each parameter until you reach the point at which
the interruption occurred. The parameter values you adjusted earlier, however, will not be
lost or altered.
NOTE
To change from °C indication to °F indication, contact Barnstead/Thermolyne.
Power Switch: Turn power switch to the "ON" position.
CAUTION
Remember that whenever the power switch is turned "ON," the furnace will begin to heat
at the setpoint temperature that was previously set in. This value will remain unchanged
for up to a year without power being applied to the control.
Furnace Power Indicator:
The amber furnace power light will illuminate whenever the door is closed. This light will go out only when
the door is open or when there is an over-temperature condition.
Door Safety Switch:
The door safety switch removes power from the heating elements when the door is opened. Open and
close door a few times, note that the amber furnace power light will go out while the door is open. If the
