Optimizing Your Process System with the WATLOW Series 988
How to Choose the Right 988 to Fit Your Application
7.8
A. Review the last six steps looking for errors and
opportunities to optimize your application’s use of
the Series 988 controller..
B. If any of the inputs or outputs are not used by
your application, check whether they could be used
to enhance your application, perhaps with the addi-
tion of an alarm or the communications option.
C. How might your needs change in the future? It's
more efficient and economical to order options now.
D. Make several copies of the worksheet on the next
page and “test drive” your application through dif-
ferent conditions. What happens if conditions ex-
ceed limits? What happens if a device breaks down?
E. Go over your work with a colleague and/or a
Watlow sales rep to check whether you have over-
looked anything.
F. If you made any changes on your worksheet,
revise your model number.
Chapter 1, Test Drives,
provides diagrams and explana-
tions of several different types of
applications.
Chapter 2, Basic Control Strate-
gies and Terms, explains the
basic concepts and vocabulary of
control applications.
