DESCRIPTION
The PAX2C Temperature/Process Controller offers many features and
performance capabilities to suit a wide range of applications. The PAX2C has a
universal input to handle various input signals including Temperature, DC
Voltage/Current and Resistance. Optional plug-in cards allow the opportunity to
configure the controller for present applications, while providing easy upgrades
for future needs. The PAX2C employs a tri-color display with seven
independently programmable color zones.
The controller has been specifically designed for harsh industrial environments.
With NEMA 4X/IP65 sealed bezel, CE compliance and extensive testing of
noise effects, the controller provides a tough reliable application solution.
MAIN CONTROL
The controller operates in the PID Control Mode for both heating and cooling,
with on-demand auto-tune that establishes the tuning constants. The PID tuning
constants may be fine-tuned and then locked out from further modification. The
controller employs a unique overshoot suppression feature, that allows the
quickest response without excessive overshoot. Switching to Manual Mode
provides the operator direct control of the output.
DISPLAY
The PAX2C features a dual line display with units annunciators, dual bar
graphs, four universal annunciators and tri-color capability. Each of the seven
display zones may be configured independently of the others, providing a visual
indication of control and/or alarm status.
ALARMS
The PAX2C has up to sixteen “soft” alarms that may be configured to suit a
variety of control and alarm requirements. These alarms may be used to monitor
and/or actuate the controller’s physical outputs as well as change display colors.
Mapped “soft” alarms may be processed independently or logically combined
using AND/OR Boolean logic.
OPTION CARDS
Optional plug-in cards provide dual FORM-C relays, quad FORM-A, quad
sinking, or quad sourcing open collector logic outputs. These cards can be used
as control outputs or for alarm indication.
A linear DC output signal is available as an optional plug-in card. The card
provides either 20 mA or 10 V signals. The output can be scaled independent of
the input range and can track the input, max and min readings or for control.
Communication and bus capabilities are also available as option cards. These
include RS232, RS485, DeviceNet, and ProfibusDP. The PAX2C can be
programmed to utilize Modbus protocol. With Modbus, the user has access to
most configuration parameters. Readout values, setpoint, process and alarm
values can be controlled through the bus. Additionally, the controller has a
feature that allows a remote computer to directly control the outputs of the
controller.
With a Windows ® based program, made available by Red Lion Controls,
configuration data can be downloaded to the PAX2C via a built-in USB
programming port.
