The last menu item for the ramp / soak function is
P E n d
.
P E n d
determines what the control
does when the program has ended. You may choose to have the program repeat (
L o o P
),
H o l d
the last set point (
1 6 S P
), revert to the local
S P 1
, or turn the outputs off (
O o F F
).
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 started.
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 different
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
P r o 9
menu
item to
O n
. 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.
Pressing the AUTO / MANUAL key will also suspend the program operation. The
difference is that AUTO / MANUAL also puts the control into manual mode. See Auto /
Manual Operation on page 18.
The function of the Primary Menu will change depending on the setting of the
S t A t
menu
item in the Secondary Menu. If
S t A t
is
O F F
then the Primary Menu is not changed.
If the
S t A t
menu item is set to
O n
, then the Primary Menu has three additional
information items added before
S P 1
appears. The first INDEX item displays the time
remaining in the current segment in the top display (####), and the message
t i
, in the
lower display. The next INDEX item displays the total time for the active segment in the
upper display (####) and the message ##
t i
(
1 t i
...
1 6 t i
), in the lower display. The third
INDEX item displays the segment set value (####) in the top display, and the message
##
S P
(
1 S P
...
1 6 S P
) in the lower display. The next INDEX press resumes the normal Primary
Menu
