Ramp / Soak Operation
When you wish to start the program, enter the Secondary Menu and set the
Prog menu item to On. 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.
Changing the AUTO / MANUAL menu item to Auto OFF will also suspend
the program operation. This also puts the control into manual mode.
Auto / Manual Control
Manual Control is enabled through the Secondary Menu. When Auto is
turned On, the lower display in the HOME position will display the output in
percent for SP1 or SP2, and is adjustable for each from 0.0 to 100 percent.
SP1 appears first with a flashing “
o
” on the right hand corner of the lower
display to represent percent. Press INDEX to display SP2 output. A
flashing "
õ
" will appear on the right hand corner of the lower display to
represent percent.
When Manual is enabled, the present control outputs are held (bumpless
transfer) and displayed. The output for SP1 or SP2 can then be manually
adjusted while displayed by pressing the UP ARROW or DOWN ARROW
key to change the value, and then the ENTER key to activate.
The Upper display will normally indicate the Process Value. Since Manual
will override most fault messages the upper display could indicate a fault
message. Refer to the Diagnostic Error Message Section for further
explanation.
