### Terminal Connection

### Configuration

Wiring Specification:

Screw tightening torque: 4.3 lb-in,

Wire range: 12~30 AWG.

Wire strip length: 6~7mm

Wiring Precaution:

The transmitter is user configurable with the user-frendly TT Configurator software and URC-1020 interface cable. The lastest version can be download free from www.texmate.com.

The URC-1020 Interface cable consist of interface converter and USB plug. It can be purchased separately. During configuration the transmitter can work alone with or without connecting to a power source.

1. Always keep signal wires away from power or contactor wires.

2. Transmitter's power supply should not be shared with

contactors, electrical motor and other inductive devices.

The various input signals are divided into three groups.

1. TC/RTD/mV: Thermocouple type (J, K, T, E, B, R, S, N, C),

The Configurable parameters are:

Pt100 and voltage input in the range of -60mVdc~60mVdc.

1. Input signal type: Various input signal type can be selected

2. Current: 0~24 mA.

3. Voltage: -10~10Vdc.

For the three different groups of input signal type, The SW1 and SW2 should be set according to the Table 2 for each channel separately. Open the cover o change the DIP switch setting.

(2) upscale (>20mA).

among the available options.

2. Unit: Select the unit (C or F) of temperature. For linear input

(voltage or current), it doesnt effect the measurement.

3. Measuring range: Defines the lowest and highest value of

measuring range. Within the range, the transmitter will convert input signals into an scalable analogue output signal.

4. Output direction: Defines the scalable analogue

output signal to be 4 to 20mA or 20 to 4mA.

5. Fault signal on sensor break: Defines the output signal to be

(3) Cut-off. Limit the output signal within the output range when the input is out of measuring range.

6. Offset Correction: Allows to eliminate the offset error of

measuring value.

7. ID & Baud Rate: Set device ID and communication baud rate.

8. 0/4~20mA Output Signal Calibration: Zero and Span adjustment of output signal. A power source shoule be connected as Figure 6.

9. Measuring value: Read the measuring value of channel 1

(PV1), channel 2 (PV2) continually.

10. Device information: Indicate the device model, firmware version, series number and communication status. Figure 5.
