Recipe Example and Comments for the 20QP Programmable Temp Controller.

Recipe: 1
Seg 1: Guaranteed Soak at 700F for 1Hr

Seg 2: Soak at 700F for 20 min with Steam Addition (EV2)
Seg 3: Ramp to 1100F over 1min (fast as possible)
Seg 4: Guaranteed Soak at 1100F for 1Hr
Seg 5: Ramp to 1200F over 1min (fast as possible)
Seg 6: Soak at 1200F for 1hr 30min
Seg 7: End of Cycle

In programming the 20QP it is important to note that each segment is either a RAMP or a SOAK.
In the Program Editor, each seg starts with a Final SP (FSP) for that segment. If the
FSP is the same as the FSP for the previous segment, then the segment is a soak. If
the FSP is different from the previous segment FSP, then the segment is a RAMP.

Thus, to do a SOAK at 700 followed by a SOAK at 1100, there must be a RAMP segment between
the segments to change the setpoint.

RAMPS may be specified by TIME or by GRADIENT (deg/hr). This is set in the program
initialization section. In this example we use TIME in hh:mm.

RAMPS and SOAKS may be GUARANTEED using Tracking Groups (TGR1-TGR10). The
tracking group parameters are specified as Deg Above and Below SP. Specified in Runtime
Group 9. In this example we have set TA1 to 10Deg and TB1 to 10Deg. Thus using TRG1 on a
SOAK segment causes the SOAK Timer to HOLD (PV display will flash) anytime the PV is outside
the BAND SP-10 to SP+10. Using TRG1 on a RAMP segment causes the RAMP SP to hold
anytime the PV falls outside the BAND SP-10 to SP+10. If you do not want to GUARANTEE a
RAMP or SOAK the n use TGR0.

Each Output Event to be used in the program must be specified in the program initialization
section. Only Output Events configured as Timer event, Break event, End of Cycle event or
End of Profile event are used (see Configuration Section 5). In the program initialization
section set these events to yes or no depending on whether the program uses the event. Only
Break events are used in the program segments. The Event Status (on/off) must be set for each
Break Event in each segment. For this Example, we have set EV1 to End of Cycle, EV2=break
(steam addition) and EV 3=break (future use).

PID Groups (PIDG1-PIDG5) may be specified in Runtime Group 4. Each program segment may
use a different PIDG. For furnace applications it is usually best to use the Primary PID settings to
do this, set the PIDG = 0 for each segment.

For the above Sample Recipe, the program edit values would be as follows:
