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.
