RAMP AND SOAK PROFILE PROGRAM

This feature allows for the elaboration of a behavior profile for the

process. Each program is composed of a set of up to 7 segments,

named RAMP AND SOAK PROGRAM, defined by SP values and

time intervals.
When the program is defined and runs, the controller starts to

automatically generate the SP according to the program.
At the end of the program execution, the controller turns the control

output off (“rvn”= no).
Up to 7 different profiles with 7 segments each can be

programmed.The figure below displays a profile model:

To execute a profile with fewer segments just program 0 (zero) for the

time intervals that follow the last segment to be executed.

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).
The ramp and soak event function is used to activate alarms at any

segment of program 1. This applies only to program 1.

LINK OF PROGRAMS
It is possible to create a more complex program, with up to 49

segments, joining the seven programs. This way, at the end of a

program execution the controller immediately starts to run another one.
When a program is created, it must be defined in the “LP" screen

whether there will be or not another program.
To make the controller run a given program or many programs

continuously, it is only necessary to link a program to itself or the last

program to the first.

EVENT ALARM
To enable this event function the alarms to be activated must be

selected for rS function and are programmed at the PE1 to PE7

prompts. The number to be programmed at the prompt defines the

alarms to be activated.
Note:
1- When recovering from power outage the controller resumes the

ramp and soak execution from the beginning of the interrupted

segment a ramp and soak program:
• Program the tolerance value, SP’s, time and event.
• If any event alarm is required program the ramp and soak event

function.

• Set the control mode to automatic.
• Habilitar a execução de programa na tela “rS “.
• Start control at the rvn prompt by selecting YES.
Before executing the program the controller waits for PV to reach the

first set point SP0. Should any power failure occur the controller

resumes at the beginning of the segment it currently is.
