RAMPING CONTRO L L E R S

Ramping Control
Programming Made
Easy Through
Advanced Technology

The SERIES F4 1⁄4 DIN industrial ramping controllers
offer an easy to set up and operate solution for the
most demanding ramp and soak processing
applications.The features and performance of these
units make them ideally suited for environmental
chamber or furnace and oven applications. Single
and dual channel versions are available.

These competitively priced controllers feature a four
line, high definition LCD interface display that makes
profile programming and controller configuration
significantly faster and easier. A 16 bit microprocessor
supports all the accuracy and performance advantages
you have come to expect from a Watlow controller.

Up to 256 steps can be programmed into as many as
40 nameable profiles. Profiles can be programmed to
wait for events or for up to three different process
variables. A guaranteed soak feature allows you to
set how closely your process needs to be controlled.

The four digital event inputs can be programmed to
remotely start, pause or terminate any of your
preprogrammed process recipes. The eight event
outputs are segment programmable, or three of them
can be assigned to programmable compressor and
boost heat/boost cool control. A real time clock can
be used to start a profile at any time.

Serial communication and dual alarm relays are
included in the base unit.The SERIES F4 ramping
controllers are packaged with a NEMA 4X front face
to withstand harsh environments and a 101.6 mm
(4.0 in.) deep case with removable connectors for
wiring convenience.

The SERIES F4 controllers are manufactured by
ISO 9001 registered Watlow Controls and backed by
a three-year warranty.

Set Point Ramp and Soak Programming

The enhanced programming features found in the
SERIES F4 ramping controllers are the result of listening
to our customers’demand for greater capabilities with
reduced programming complexity.

A profile guide leads the programmer through the
programming process by offering choices for step
configuration.For better operator recognition, profiles
and digital I/O used for events can be given names of
up to 10 characters in length.

Five step types including ramp, soak, jump, auto start
and end offer the programmer complete flexibility.

Temperature and Humidity Chamber Application

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. Up to eight eve n t
outputs are step selectabl e. Since your thermal systems
c h a ra c t e ristics may change 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 set
date, a day of the week or daily, the choice is yours.
The jump step can be used to jump within a profile or to
another profile.The end step terminates a program with
the control outputs programmed to your process needs.

Serial Communication

EIA-232 and EIA-485 serial communication interfaces
are included in the base unit of both the SERIES F4S
(single channel) and the SERIES F4D (dual channel)
controllers.The baud rate is selectable as either 9600
or 19200 Kbaud.The protocol is Modbus™.

Alarms

Two Form “C” electromechanical alarm relays are
included in the base units.These alarms can be
programmed as either process or deviation alarms.
The alarms can be tied to up to three process variables.

Optional Retransmit

Optional retransmit capability is available to retransmit
one or two variables. These variables include up to
three process variables, control set points or percent
load power.
