• In the case of a multi-step recipe, the top line of the display will change to rS.S1rS.S1
(ramp/soak soak 1). The recipe will continue to execute, maintaining the setpoint
at soak level 1 for the duration of soak time 1. The recipe will then begin to
execute the next segment, and the display will change to rS.r2rS.r2, alternating with
the process variable on the top line, and the setpoint on the lower line.
To pause a recipe or single-setpoint ramp during its execution:
1. Press the key until CtrLCtrL is displayed on the top line. The lower line will show
rS.HrS.H (ramp/soak hold).
2. Press the key once to go into recipe hold mode. The top line of the diplay will
show rS-HrS-H alternating with the process value, while the lower line displays the
setpoint. The setpoint will remain at this level until you take the recipe out of hold.
To resume execution of a held recipe:
1. Press the key until CtrLCtrL is displayed on the top line. The lower line will show
FOPFOP (fixed output percentage).
2. Use the or key to display r.Sr.S rr (ramp/soak run/resume).
3. Press the key once to resume execution of the recipe. The top line of the display
will again show the current ramp or soak segment number, alternating with the
process value, while the lower line displays the setpoint.
To terminate execution of the recipe:
1. Press the key until CtrLCtrL is displayed on the top line. If the recipe is active, the
lower line will show rS.rS. HH (ramp/soak hold).
2. Instead of pressing the key to select ramp/soak hold, use the or key to
display nornor (normal) or FOPFOP (manual mode).
3. Press the key once to terminate execution of the recipe.
• If you selected normal mode, the top line of the display will show the process
variable. The lower line will show the setpoint. This setpoint will be at whatever
value the recipe had reached while executing. This is different from what
happens if a recipe completes execution normally. In that case, the setpoint
value will be determined by the termination state configured using the ramp/soak
menu as described in 11.4.2.
• If you selected manual mode, the top line of the display will show the process
variable. The lower line will show Pct1Pct1 alternating with the current fixed output
percentage.
