7.7 Ramp and Soak Profile Program
Seven ramp and soak profiles with up to 7 segments each can be programmed. Longer profiles
of up to 49 segments can be created by linking 2 or more profiles.
Example of a complete ramp and soak profile
To execute a profile with fewer segments just program 0 (zero) for the time intervals that follow
the last segment to be executed.
Example of a profile with fewer segments (T4 is set 0)
The program tolerance “Ptol” defines the maximum deviation between PV and SV for the
execution of the profile. If this deviation is exceeded, the program will be interrupted until the deviation
falls to within the tolerance band. Programming 0 (zero) at this prompt disables the tolerance and the
profile execution will not to be halted even if PV does not follow SV (time priority as opposed to SV
priority).
Example of two linked programs
The ramp and soak event function is used to activate alarms at any segment of program 1. This
applies only to program 1. To enable this event function the alarms to be activated must be selected for
rS function and are programmed at the PE 0 to PE 7 prompts. The number to be programmed at the
prompt defines the alarms to be activated. To configure and execute a ramp and soak program:
Program the tolerance value, SV, time and event.
If any event alarm is required program the ramp and soak event function.
Set the control mode to automatic.
Select ramp and soak program to be executed at prompt Prn (0 to 4)
Start control at the run prompt rvn by selecting YES.
