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.

can be programmed to wait for events or for up to three different process variables.

A guaranteed soak feature allows a setting for how closely to control a process.

Program the four digital event inputs to remotely start,pause or terminate any

preprogrammed process recipes.

Eight event outputs are segment programmable and three outputs can be assigned

to a programmable compressor and boost heat/boost cool control.

A real-time clock can start a profile at any time.

Serial communication and dual alarm relays are included in the base unit.

The SERIES F4 ramping controller is packaged with a NEMA 4X front face to

withstand harsh environments and a 4 in. (102 mm) deep case with removable

connectors for wiring convenience. It is manufactured by Watlow, ISO
