Screw terminals are pro- vided. Make appropriate connections using proper size wire for rated controller load power circuits. - Page 6 Power Wiring Circuits Typical Wiring Diagrams Figure 2b: Typical 120 Vac for -B & -T Output -F, -S Output - 120/240 Vac The -F output is 20 mA at the low temperature end of the pro- portional band and 4 mA at the upper end of the proportional band.

Page 7: Thermocouple Wiring Circuits
Thermocouple Wiring Circuits Use thermocouple and extension wire that conforms to the appropriate thermocouple type specified on the serial number tag. In thermocouple circuits, the negative lead is colored red. Extension wires must be of sufficient size so that on long runs the thermocouple circuit resistance does not exceed 100 ohms. -
Page 8: Operation
The typical control system contains the sensor, controller (2000/3020) Operation and the process (load). The sensor produces a small signal propor- tional to the measured temperature of the process. This signal is amplified by the controller, where it is compared with setpoint tem- perature. -

The pro- portional band adjustment is on the right side and sets the gain of the controller. The offset (manual reset) adjustment is on the left and corrects for offsets from the setpoint tempera- ture. -
