The controller has now been given a new
value for START DELAY. The new values
reside in the NEW ENTRIES area of the
controller memory. To make these changes
active, press the RESTART key, then again
press it to confirm your choice. The
controller will then wait until it receives a
contact closure (at the External Start inputs
on the terminal block). The contact must
remain closed for the length of time
programmed in the steps above.
Summary of Sequence:

5.4 Programming SAMPLE INITIATION
5.4.1 SAMPLE INITIATION Overview
SAMPLE INITIATION is the function that will determine the frequency that
samples are drawn. There is available on the Touchpad a variety of options to
enhance the capabilities of this function. When the Sample Initiation has been
chosen to be set, a list of options is presented as flashing text below the main
heading of the function selected. The list is advanced using the ARROW keys
(any direction) until the desired option is displayed. These options are
programmable from the Touchpad and require only that the sampler have the
correct equipment configuration to utilize them. The last option selected in
previous programming will be the first to appear on the display.
The display showing disabled will reflect
the fact that the function is not being used.
Sampler operation can be started at uniform
intervals. This option allows an interval time
to be set between sample cycles.
