More detailed descriptions are provided, when required, in the operating sections of the manual. Displays The 650/750 Series controller features two bright, one- half inch LED numeric displays used in setting up the fur- nace program or reading out the furnace temperature.

  • Page 9: Keypads

    ONTROLS Keypads The 650/750 Series incorporates a four-key, tactile key- pad. The function of each key is discussed individually below. See Fig. 1 for keypad locations. During programming or setup, successively MENU pressing the MENU key causes the controller display to sequentially step through menu selec- tions.

  • Page 10: Operation

    Operation The 650/750 Muffle Furnaces feature two modes of operation: • Control • Ramp and Soak Each is discussed separately in the following sections. Control Mode In Control mode, the muffle furnace maintains a set tem- perature until that set temperature is changed. To set a temperature and initiate Control mode operation, perform the following: Place the power switch in the ON position.

  • Page 11: Program Step

    PERATION Program Steps A program consists of a sequence of operations or "steps" which the muffle furnace is set up to perform. The pro- grammed operations are executed in the order entered: step 1, step 2, step 3, etc. A single program may have a maximum of 24 steps, or as few as two (one must be an End).

  • Page 12: Creating A Ramp And Soak Program

    PERATION Creating a Ramp and Soak Program Note During programming, the MODE key Creating a program consists of constructing a sequence serves as an "enter" key to select a of the four basic operations, Set Point (ramp), Soak, value shown on the Actual Display Jump Loop and End, to produce a desired temperature for a corresponding parameter cycle.
  • Page 13 PERATION If a ramp to a Set Point is selected, the Set Display first indicates "SP" to signify that the operator must select a final target temperature, or set point. Use the UP or DOWN Arrow key to adjust the Actual Display to indicate the desired final temperature for the ramp.
  • Page 14 PERATION 14. The Set Display then shows "SEC" to indicate that the operator must select the number of additional seconds for which the current set temperature will be held. Use the UP or DOWN Arrow key to adjust the Actual Display to indi- cate the desired number of soak seconds (maxi- mum of 59).
