Set Point Ramp and Soak Programming

In response to customer needs, the Watlow SERIES F4

ramping controller has been enhanced with programming

features that offer more capabilities with less programming

complexity.

A programming guide provides step-by-step instructions for

building profiles, offering choices for step configuration. For

better operator recognition, profiles and digital I/O used for

events can be named using up to 10 characters.

Five step types including ramp, soak, jump, auto start and

end, offer complete programming flexibility.

Ramp steps can be based on time or rate. Ramp and soak

steps can be programmed to wait for up to four event inputs

and three process variables. As many as eight event outputs

are step selectable. To accommodate changes to thermal

systems characteristics over the operating range, up to

10 sets of PID heat/cool parameters are step selectable.

The auto start step can start a profile based on a chosen

set date, day of the week or daily. A jump step enables

movement within a profile or to another profile. The end step

terminates a program with the control outputs programmed

to specific process needs.
