EV1 through 4 From 1 to 4 events may be programmed into the soak portion of
each segment here. These typically involve actuating/disabling
relays to close/open valves or perform other relay-controlled
functions. NOTE: These will only actuate when the controller has the
relay cards installed and programmed for an event.
Guaranteed
Soak Band
If the process temperature deviates from the setpoint by more than
this value, the timer is placed in a hold condition. The timer
continues when the process temperature falls within range.
Hi Limit SP
The high limit setpoint may be entered here; if the temperature
exceeds this value, the hi-limit will alarm and shut off the heater. See
Notes on Soak Temp and Hi Limit SP, below.

Temp. Units
Selects degrees Fahrenheit or Centigrade, for the recipe display
only. Recipes stored on the host PC, like profiles in the Protocol
Plus, are always stored with temperatures in degrees Fahrenheit,
regardless of the selected viewing units. Note that changing the
display units converts displayed recipe temperatures accordingly.
OPEN/SAVE
(to Folder)
These buttons enable the operator to open a new recipe, or save the
current one to a predetermined folder.
READ/WRITE

These buttons enable the operator to upload a recipe from one of
the Protocol Plus controllers in the system, or to write the current
recipe to one of the controllers.
Profile
Number

or writing recipes.
Notes on Soak Temp. and Hi Limit SP Values
In the recipe editor screen, Soak Temp and Hi Limit SP values can be adjusted in the
range of -18 to 538 C (0 - 1000 F). Errors may occur attempting to download a recipe
to a Controller's profile if one of the recipe's ramp times, soak temperatures, or the high
limit setpoint value is incompatible with the range set internally for the target controller.
In this case, an error message similar to Figure 23 will be displayed, and no changes
will be made to the Controller's profile.
