The
F4 Programmable Controller features a four line, high definition
LCD interface display that makes profile programming and controller
configuration significantly faster and easier. A large LED readout
indicates the actual chamber temperature with 0.1°C or °F display
resolution. Internal logic provides refrigeration compressor
control based on the demand for cooling for responsive and reliable
performance.
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.
Set Point
Ramp and Soak Programming
The enhanced programming features found in the F4 controller are
the result of listening to our customers' demand for greater capabilities
with reduced programming complexity. Up to 256 steps can be programmed
into as many as 40 namable profiles.
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.
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.
Serial Communication
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. With it you could read all of
the controllers parameters with a few read commands.

Alarms
Two Form "C" electromechanical alarm relays are included.
These alarms can be programmed as either process or deviation alarms.
The alarms can be tied to up to three process variables. (The chamber
also has an independent High/Low Limit Controller with an audible
alarm which is used as a safety device.)
Optional
Analog Retransmit
Analog retransmit capability is available to retransmit two variables.
These variables include chamber temperature, temperature set point
or percent control power.
Optional
GPIB Interface
Converts the controller's serial interface to GPIB.

Optional
Ethernet Interface
Converts the controller's serial interface to Ethernet. It is fully
VXI-11.3 compliant so it fits in with todays new test equipment
architectures that use Ethernet networks. VXI-11 is a communication
standard developed by the VISA consortium in 1995 in conjunction
with the VISA Specification. VXI-11.3 is the sub-specification
for network instruments.
