While in the programming menu, you can also:
• Delete - To delete the current step, press DELETE (D). A deleted
step cannot be recovered. Used repeatedly, this command can be
used to delete an entire file.
• Review - To review existing program steps, press
STEP BACK (A) or STEP FWD (B).
• Add New - To add a new step between two existing steps,
navigate through the program to the step just before your
addition. Press INSERT (C) and program the new step.
The initial value of the next step will default to the final value of the
new step, and may need to be edited if a different initial value is
needed.
• While Running - A gradient program can be reviewed or edited
while it is running. Simply press EDIT (B) or REVIEW (C) to
begin. If a new step duration is shorter than the elapsed time for
that step, the program will proceed to the next step. If the total
flow rate is changed, the program will immediately start using
the new rate.
To return to the run screen, press RETURN (D).
• Hold - You can hold a running gradient in its current state while
retrieving a different program file to run in its place. Press Hold
and then Recall to access the new program.
This feature is used mainly in applications where it is necessary
to keep the system pressurized during method changes.
• External Start - When a gradient program is in Hold Mode, a
momentary low on digital input '2' of the controller ACCESSORY
connector will start the program.
When a gradient program reaches the end, there are four selectable
actions the system can then perform:
• Hold the final value (example shown below)
• Stop after the final step
• Return to the initial value and hold it
• Return to the initial value and repeat the program
While the system is in Gradient Mode, these options can be edited at
any point before or after gradient programming, and while a gradient
is running.
