TestEquity TE-F4-TEMP – Legacy Temperature Controller

• Legacy F4 controller
• Originally developed in 1998
• Only recommended for legacy applications
• For modern features and improved functionality, the standard F4T Touch Screen Controller is recommended
• Profiles are easily entered, stored and recalled using the controller’s front panel keys, without the need for a computer

The F4 controller features a four-line, high definition LCD interface display for manual operation, profile programming and controller configuration. A large LED readout indicates the actual chamber temperature with 0.1°C or °F display resolution. Up to 256 steps can be programmed into as many as 40 namable profiles. Navigation and settings are accomplished with arrow keys. Includes an RS-232 Serial Modbus RTU interface.

The controller is packaged with a NEMA 4X front face to withstand harsh environments. It is manufactured for TestEquity by Watlow and backed by a three-year warranty.

Please note – this product is only recommended for legacy applications. For modern features and improved functionality, the standard F4T Touch Screen Controller is recommended.

The enhanced programming features found in the F4 controller are the result of listening to customers’ demand for greater capabilities with reduced programming complexity. Up to 256 steps can be programmed into as many as 40 namable profiles. These profiles are easily entered, stored and recalled using the controller’s front panel keys, without the need for a computer.

A profile guide leads you 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 you complete 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. Up to seven event outputs are step selectable. Five sets of PID heat/cool parameters are also step selectable. The auto start step can start a profile based on a set date, a day of the week, or daily. The jump step can be used to jump within a profile or to another profile.

RS-232 and RS-485 serial communication interfaces are included. The baud rate is selectable as either 9600 or 19200 baud. The controller uses Modbus RTU protocol. Modbus enables a computer to read and write directly to registers containing the controller’s parameters.
