TRANSDUCER TE232-102D, TE485-102D Programmable temperature transducer for RTD Pt1000 sensor with serial output RS232 and RS485 Instruction manual
Instruction Manual for use of transducer: TE232-102D (RS232), TE485-102D (RS485) Transducer is designed for temperature measurement at °C or °F by means of the external temperature probe with RTD Pt1000 sensor. It is built in a plastic case with the IP65 protection. Read this manual before the first transducer connection. Transducer TE232-102D communicates via link RS232, transducer TE485-102D via link RS485.
The cable should be led in one line, i.e. NOT to „tree“ or „star“. Termination resistor should be located at the end. For short distance other topology is allowed. Terminate the network by a termination resistor. The value of the resistor is recommended about 120 Ω. For short distance termination resistor can be left out. The cable should not be led in parallel along power cabling. Safety distance is up to 0.5 m, otherwise undesirable induction of interference signals can appear.
Typical application wiring, connection of terminals TE232-102D – power from communication TE232-102D – power from external voltage port source TE485-102D – RS485 4
Info mode If in doubt of setting of installed transducer, verification of its address is enabled even without using computer. Power should be connected. Unscrew transducer cover and shortly press button next to connection terminals (jumper must be open). Actual adjusted address of transducer is displayed at decimal code. Next press of button exits info mode and actual measured values are displayed. Note: No measurement and communication is possible during info mode.

ARION communication protocol - AMiT company The device supports communication protocol ARiON version 1.00. For more details see www.amit.cz. Error states of the device Device continuously checks its state during operation. In case error is found LCD displays corresponding error code: Error 0 First line displays „Err0“. Check sum error of stored setting inside device’s memory. This error appears if incorrect writing procedure to device’s memory occurred or if damage of calibration data appeared.

Appendix A Connection of ELO E06D converter (RS232/RS485) (optionally accessory of the transducer TE485-102D) The ELO E06D converter is an optional accessory for connection of transducer/transducers with RS485 interface to the PC via serial port RS232. Connect connector marked RS232 directly to the PC, connect power to connector marked RS485. Power voltage +6V DC from an external acdc adapter connect to pin 9, 0V connect to pin 5. Also mutually connect pin 2 and pin 7.
