THERMOLYNE F6000 711 Series - Setpoint Adjustment and Controller Tuning; Adjusting Setpoint and Initiating Self-Tuning

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.
