X means not latched.R means can read data by using FROM command or RS-485. W means can write data by using TO command or RS-485.LSB (Least Significant Bit): 1. Voltage input: 1 LSB =10V/8,000=1.25mV. 2. Current input: 1 LSB =20mA/4,000=5μA.Explanation:1. CR#1: CR#1 is used to set 4 inner channels working mode of analog input module. Everychannel has four modes to set and can be set individually. For example: if setting CH1 to mode 0(b2~b0=000), CH2 to mode 1(b5~b3=001), CH3: mode2 (b8~b6=010), CH4: mode3(b11~b9=011). It needs to set CR#1 to H0688 and the upper bit (b12~b15) will reserved. Thefactory setting of CR#1 is H0000.2. CR#2 ~ CR#5: it is used to set average times of CH1~CH4. Setting range is K1~K100 and factorysetting is K10.3. CR#6 to CR#9 are the average value that calculates according to the value that is set inCR#2~CR#5 (average time of CH1~CH4 input signal). For example, if CR#2 (the average timesof CH1) is 10, it will calculate the average of CH1 input signal every 10 times.4. CR#12 ~ CR#15: display present value of CH1~CH4 input signal.5. CR #18~ CR #21: the content is the value of adjusting OFFSET value of CH1~CH4 if analog inputvoltage or current is 0 after it transfers from analog to digital. Voltage setting range:-5V~+5V(-4,000 LSB~+4,000 LSB). Current setting range: -20mA~+20mA (-4,000 LSB~+4,000 LSB).6. CR #24~ CR #27: means analog input voltage or current when conversion value from analogsignal to digital is 4000. Voltage setting range: -4V~+20V(-3,200 LSB ~+16,000 LSB). Current settingrange: -16mA~+52mA(-3,200 LSB ~+10,400 LSB). But it needs to notice that GAIN VALUE –OFFSET VALUE = +800 LSB~+12,000 LSB (voltage) or +800 LSB~+6,400 LSB (current). When this valueunder this range, the resolution of the input signal will be thin and the variation of value will belarger. When this value exceeds this range, the resolution of input signal will be thick and thevariation of value will be smaller.7. CR#30 is fault code. Please refer to the following chart.Fault description Content b15~b8 b7 b6 b5 b4 b3 b2 b1 b0Power source abnormal K1(H1)Reserved0 0 0 0 0 0 0 1Analog input value error K2(H2) 0 0 0 0 0 0 1 0Setting mode error K4(H4) 0 0 0 0 0 1 0 0Offset/Gain error K8(H8) 0 0 0 0 1 0 0 0Hardware malfunction K16(H10) 0 0 0 1 0 0 0 0Digital range error K32(H20) 0 0 1 0 0 0 0 0Average times setting error K64(H40) 0 1 0 0 0 0 0 0Command error K128(H80) 1 0 0 0 0 0 0 0Note: Each fault code will have corresponding bit (b0~b7). Two or more faults may happen at the same time.0 means normal and 1 means having fault.8. CR#31: it is used to set RS-485 communication address. Setting range is 01~255 and factorysetting is K1.9. CR#32 is used to set RS-485 communication baud rate: 4,800, 9,600, 19,200, 38,400, 57,600,115,200 bps. b0: 4,800bps. b1: 9,600bps. (factory setting) b2: 19,200bps. b3: 38,400 bps. b4:57,600 bps. b5: 115,200 bps. b6~b13: reserved. b14: exchange low and high byte of CRC checkcode. (only for RTU mode) b15=0: ASCII mode. b15=1: RTU mode. Communication format: ASCIImode is 7Bit, even bit, 1 stop bit (7,E,1). Communication format of RTU mode is 8Bit, even bit, 1stop bit (8,E,1).10. CR#33 is used to set the inner function priority. For example: characteristic register. Outputlatched function will save output setting in the inner memory before power loss.11. CR#35~ CR#48: system used.12. The corresponding parameters address H4000~H4022 of CR#0~CR#34 can provide user toread/write data by RS-485.a) Communication baud rate: 4,800, 9,600, 19,200, 38,400, 57,600, 115,200 bps.b) Communication format: ASCII mode is 7Bit, even bit, 1 stop bit (7,E,1). Communicationformat of RTU mode is 8Bit, even bit, 1 stop bit (8,E,1).c) Function code: 03H—read data from register. 06H—write a WORD into register. 10H—writemany WORDs into register.4 ADJUST A/D CONVERSION CHARACTERISTIC CURVE4.1 Adjust A/D Conversion Characteristic CurveVoltage input mode:+8000+4000-400010V-8000-6V-10V6V5V2V0GAINOFFSETBitsVoltsMode 0 of CR#1 GAIN=5V (4,000 LSB ), OFFSET=0V (0LSB)Mode 1 of CR#1 GAIN=6V (4,800 LSB ), OFFSET=2V(1,600 LSB )GAIN: Voltage input value when digital output is4000.

Users can adjust conversion characteristic curve by changing OFFSET values(CR#18~CR#21) and GAIN values (CR#24~CR#27) depend on application.LSB(Least Significant Bit): 1. voltage input: 1LSB=10V/8,000=1.25mV.2. current input: 1 LSB=20mA/4,000=5μA.4.2 Program Example for Adjusting A/D Conversion Characteristics CurveSetting OFFSET value of CH1 to 0V(=K0 LSB) and GAIN value of CH1 to 2.5V(=K2,000 LSB).X0K2000K24H0 K1K0K1H0 K1M1002K0K33K1K0 K1K18 K0K0TOTOTOTO1.

Installation of the DIN railThe ELC can be secured to a cabinet by using the DIN rail that is 35mm high with a depth of 7.5mm.When mounting the ELC on the DIN rail, be sure to use the end bracket to stop any side-to-sidemotion of the ELC, thus to reduce the chance of the wires being pulled loose. At the bottom of theELC is a small retaining clip. To secure the ELC to the DIN rail, place it onto the rail and gently pushup the clip.To remove it, pull down the retaining clip and gently pull theELC away from the DIN rail. As shown on the right:When installing the ELC, make sure that it is installed in anenclosure with sufficient space (as shown on the right) to itssurroundings so as to allow heat dissipation.DDD DELCD>50mm2. Wiring22-16AWG<1.5mmNotes:1. Please use 22-16AWG (1.5mm) wiring (either single or multiplecore) for I/O wiring terminals. The specification for the terminals isas shown on the left. ELC terminal screws should be tightened to1.95 kg-cm (1.7 lb-in). Use Copper Conductor Only, 60/75 °C.2. I/O signal wires or power supply should not run through the samemulti-wire cable or conduit.6 INITIAL ELC START-UPLamp display:1. When power is on, POWER LED will be lit and ERROR LED will be lit for 0.5 second.2. When it is normal that POWER LED should be lit and ERROR LED should turn off.When power supply is lower than 19.5V, ERROR LED will blink continuously till thepower supply is higher than 19.5V.3. When it connected to ELC in series, RUN LED on ELC will be lit and A/D LED or D/ALED should blink.4. After receiving the first RS-485 command during controlling by RS-485, A/D LED or D/ALED should blink.5. After converting, ERROR LED should blink if input or output exceeds upper bound orlower than lower bound.Example:K1K0 K1 K1K0K0K0M1000FROMTOK2D0H618K32TOK0K2ENDK6 D20 K4FROM= H88 D0M1002= H88 D01.
