The CN9000A digital temperature controllers feature high accuracy and reliability, and the
sophisticated PID with approach control for optimal control during start-up and steady-state
operation. These units are well suited for a broad range of applications, and are easy to install
and operate. The unique, sophisticated autotune algorithm will calculate the optimum PID values,
and additionally recommends the best value for cycle time. For most applications, the user need
only select the desired input type, simply by using the front pushbuttons. The autotune parameters
can be changed by the operator at any time, allowing the operator to fine tune the controller to
an individual process.
The microprocessor holds all data in non-volatile memory, with the ability to retain data for
10 years with no power. The CN9000A has a large, 31/2 digit green LED readout, with auxiliary
indicators for each output, and 3 LEDs to indicate deviation from setpoint.
Selection of all operational controls is made through the keys on the front panel, with the display
prompting the user through each step. After the parameters have been set, they can be locked-in,
simply by removing a jumper located behind the front bezel. The user can select the control mode
and parameters, display resolution (1 or 0.1°), and units (°F/°C). The operator can also utilize
the ranging feature, which limits the range in which the setpoint may be chosen, or lockout a user
from changing the setpoint. The new single setpoint controller has rear termination. The optional
second setpoint and output of the CN9000A model may be set for proportional, on-off or latching
limit control, and can be set as either a tracking or non-tracking setpoint. Cycle time,
proportional band and on-off deadband are all set independently of the primary setpoint.
