EVD120 Important [ EVD120 ] Important Important Read these instructions carefully before installing and using the instrument and follow all additional information for installation and electrical connection; keep these instructions close to the instrument for future consultations. The instrument must be disposed according to the local legislation about the collection for electrical and electronic equipment.
EVD120 Introduction [ EVD120 ] Introduction Introduction EVD120 is a two analog channels and two digital inputs acquisition module. Each analog channel can work with one of the following kind of probe (universal analog channels): • PTC/NTC probe • J/K thermocouple • 2/3 wires Pt 100 and Pt 1000 probe • 2/3 wires 4-20 mA passive current transducer • 0-10/2-10 V and 0-20/4-20 mA active transducer.
EVD120 Getting started [ EVD120 ] Getting started 1 Getting started 1.1 Installing the instrument On DIN rail; dimensions in mm (in). Fig. 1 - Dimensions of EVD120. Fig. 2 - Installation of EVD120. Additional information for installation: • working conditions (working temperature, humidity, etc.) must be between the limits related in the technical data • do not install the instrument close to heating sources (heaters, hot air ducts, etc.
EVD120 Getting started 1.2 Wiring diagram Fig. 3 - Wiring diagram of EVD120. With reference to the wiring diagram: • port 1 is the port for the serial communication (via RS-485, with MODBUS communication protocol) • port 2 is the serial port for the communication with the programming key.
EVD120 Programming [ EVD120 ] Programming 2 Programming 2.1 Preliminary remarks EVD120 supports the MODBUS communication protocol. The kind of network EVD120 can work in is RS-485 (look at Fig. 4); for further information on the realization of the network, consult the Installation manual of RICS for Windows® (the document is available in the CD of RICS). According to the standard settings: • the instrument address has value 247 • the baud rate has value 9,600 baud • the parity has value even.

EVD120 Programming • press the button of EVKEY 1 s: LED Prog of EVD120 will flash and the LED of EVKEY will shed green light and • press and release the button of EVKEY: the LED of EVD120 will go out; if the LED of EVKEY sheds green light red light alternatively (6) consider value 0, if it sheds red light consider value 1 (6) the value to consider is not the instrument address; the instrument address is the sum of all the values to consider in the procedure • press and release the button of EV
EVD120 Programming • press and release the button of EVKEY: LED Power/Status and LED Communication of EVD120 will light up; if the LED of EVKEY sheds green light consider value 0, if it sheds red light consider value 64 (6) • press and release the button of EVKEY: all the LED of EVD120 will light up; if the LED of EVKEY sheds green light consider value 0, if it sheds red light consider value 128 (6) • press and release the button of EVKEY: the procedure will be quitted, LED Prog of EVD120 will flash an
EVD120 Programming 2.6 Copying the configuration parameters of EVD120 in the programming key EVKEY using the software Params Manager Operate as follows: • make sure to have the programming key EVKEY • switch on the power supply of EVD120 and wait 4 s at least since the power supply has been switched on • connect EVKEY to port 2 of EVD120: the LED of EVKEY will shed green light Fig. 5 - Connecting EVKEY to port 2 of EVD120.

EVD120 Signals [ EVD120 ] Signals 4 Signals 4.1 LED Power/Status If it is lit, the instrument will be supplied. If it flashes, an analog channel 1 error and/or an analog channel 2 error will be running. Remedies: • look at parameters “Probe kind 1” and/or “Probe kind 2” • check the integrity of the probe • check the connection instrument-probe • check the variable read by the probe. If it is out, the instrument will not be supplied. 4.
EVD120 Signals If it flashes, the instrument will read some data but it will not be the recipient. Remedies: • look at parameters “instrument address” of the instruments of the RS-485 network. If it is mainly out, the instrument will read some not correct data. Remedies: • look at parameters “baud rate” and “parity” of the instruments of the RS-485 network. If it is out, the serial communication will not be running. 4.
