5.0 Changing Ramp/Soak Cycle Settings
The settings in the cycle recipe can be changed to the user’s needs. The
temperature set points, ramp times, soak times, and number of cycles can
be changed by going into the recipe menu. One cycle can have up to eight
temperature set points. Each temperature set point has an associated ramp time
to reach that temperature set point and a soak time at that temperature. This
controller is preset to have two temperature set points in a cycle.
5.1: Setting Recipe Options
1) Press the Menu button (see figure 4A) on the front of the controller and hold
it down for at least three seconds until the display changes.
2) Press the Menu button again quickly to change the red display. It may be
necessary to press the Menu button several times until the red display reads
“r-S” (Figure 9).
3) Press the Mode button and the green display will show the first cycle recipe
setting. The green display should alternate between “rOPt” (Figure 10) and
“8.r.S”. There are three setting options: “8.r.S”, “S.SP.r”, and “diS”. The
settings can be changed by pressing the up or down arrow buttons This
setting should remain on “8.r.S”. Otherwise, the recipe function will not
cycle between the two temperature set points.
