The West 4400 profile controller is a microprocessor based, single loop, 1/4 DIN controller with programmable setpoint programs.
The West 4400 profile controller can function either as a basic 1/4 DIN process controller utilizing manual setpoint changes, or it can execute any one of eight setpoint programs. Each program is adjustable in the range of 1 to 16 segments and are cascadable to a maximum length of 121 segments. Each segment may be a ramp, a dwell, a join, or an end. A delayed start feature is standard to the West 4400 profile controller as well as an end of program relay. By using the auto-hold feature, assured dwells are possible.
Universal inputs that are standard to the 1/4 DIN West 4400 profile controller include thermocouple, RTD (PT100), or DC linear-user-selectable. Standard outputs include two 4-20mA current outputs to be used for control and a third current output to be used for retransmission. In lieu of current control outputs, relays or SSR drivers are available to the West 4400 profile controllers. Four event outputs (relays) are available as an option.
Two automatic tuning types come standard with the West 4400 profile controller. The Pre-Tune facility is used to set the profile controller's PID control parameters to values which are approximately correct in order to provide a base from which the Self-Tune facility may subsequently optimize tuning. The Self-Tune facility is used to optimize tuning while the controller part of the West 4400 profile controller is operating. Auto/manual control is user-selectable with "bumpless" transfer into and out of manual control.
The West 4400 profile controller has comprehensive front panel displays that display the process value and the setpoint.
