Set
1SP to the target value desired for the first ramp. This value is in actual units just
like SP1. If the control is programmed for temperature, then the SP displays are in
temperature. If the control is programmed for some other engineering unit, the SP is
set in that unit.
Press INDEX to continue. If Alarm 1 is programmed as an event (AL1 = EUnt),
then 1A1 will appear. If you wish the Alarm 1 contact to function for this segment,
set 1A1 is set to 0n. If not, set for 0FF. Press ENTER. When 1A1 is set 0n, the
Alarm 1 function will be active for entire period set 1t above.
Complete setting the segment times (2ti . . . 16ti ), segment set point (2SP . . .
16SP), and event alarms (2A1 . . . 16A1) to 0n or 0FF.
For unneeded or unused segments set the segment times (2ti . . . 16ti ) to 0, and
set the segment set point (2SP . . . 16SP) to the same value as the last active set
point. A segment alarm may be set to indicate “end of run” at the segment number
you select.
The last menu item for the ramp / soak function is PEnd. PEnd determines what the
control does when the program has ended. You may choose to have the program
repeat (LooP), HoLd the last set point (16SP), revert to the local SP1, or turn the out-
puts off (0oFF).
It is important to remember that if you want the program to repeat, you must allow
the process to return to the same condition that existed when the program first start-
ed. Remember that the ramp function calculates the slope by drawing a line from the
beginning PV to the ramp target set point. If the PV at the end of the program is dif-
ferent than the PV at the initial start, the ramp will calculate differently.
Ramp / Soak Operation
When you wish to start the program, enter the Secondary Menu and set the Pro9
menu item on 0n. Return to the HOME position by waiting for the display to time out
or by pressing the UP ARROW & ENTER keys and then the
DOWN ARROW & INDEX keys.
The home display will read as it normally does. The HOLD indicator by the RUN /
HOLD key will be lit. To start the program press the RUN / HOLD key for
three seconds. The HOLD indicator will go out, and the program will start.
To suspend the program at any time, press the RUN / HOLD key. Press the key
again to resume.
