Instruction Sheet
WARNING
•This Instruction Sheet only provides descriptions for electrical specifications, general
specifications, installation & wiring, troubleshooting and peripherals. For more information about
the optional peripherals, please see ELC Application Manual.
•This is an OPEN TYPE Controller. The ELC should be kept in an enclosure away from airborne
dust, humidity, electric shock risk and vibration. Also, it is equipped with protective methods
such as some special tools or keys to open the enclosure, so as to avoid the hazard to users
and the damage to the ELC. Do NOT touch terminals when power on.
•Never connect the AC main circuit power supply to any of the input/output terminals, as it will
damage the ELC. Check all the wiring prior to power up. To avoid any electromagnetic noise,
make sure the ELC is properly grounded .
•Warning – Do not disconnect while circuit is live unless area is known to be non-hazardous.
•Power, input and output (I/O) wiring must be in accordance with Class 1, Div. 2 wiring methods -
Article 501-10(B)(1) of the National Electrical Code.
•Suitable for use in Class 1, Division 2, Groups A, B, C, D or Non-Hazardous locations only.
•Warning – Explosion hazard - Substitution of components may impair suitability for Class 1,
Division 2.
•Warning – Explosion Hazard - Do not disconnect equipment unless power has been switched
off or the area is known to be Non-Hazardous.
1 INTRODUCTION
1.1 Model Explanation and Peripherals
Thank you for choosing Eaton Logic Controller (ELC) series products. The analog input module
receives external 4-point analog signal input (voltage or current) and transforms it into 14 bits digital
signal. The analog input module of ELC-AN04ANNN can read/write the data of analog input module
by using commands FROM / TO via ELC program. There are 49 CR (Control Register) in each
module and there are 16 bits in each register.

ELC-AN04ANNN EXPLANATION
#34 H 4022 O R System Version It is hexadecimal to display software version. For example: H 010A means
1.0A.
#35~#48 System used
O means latched. 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: 1LSB=10V/8,000=1.25mV. 2. Current input: 1LSB=20mA/4,000=5μA.
Explanation:
1. CR#1: CR#1 is used to set 4 inner channels working mode of analog input module. Every
channel 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: mode
3(b11~b9=011). It needs to set CR#1 to H0688 and the upper bit (b12~b15) will reserved. The
factory 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 factory
setting is K10.
3. CR#6 to CR#9 are the average value that calculates according to the value that is set in
CR#2~CR#5 (average time of CH1~CH4 input signal). For example, if CR#2 (the average times
of 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 input
voltage or current is 0 after it transfers from analog to digital. Voltage setting range:
-5V~+5V(-4,000LSB~+4,000LSB). Current setting range: -20mA~+20mA (-4,000LSB~+4,000LSB).
6. CR #24~ CR #27: means analog input voltage or current when conversion value from analog
signal to digital is 4000. Voltage setting range: -4V~+20V(-3,200LSB~+16,000LSB). Current setting
range: -16mA~+52mA(-3,200LSB ~+10,400LSB). But it needs to notice that GAIN VALUE –
OFFSET VALUE = +800LSB~+12,000LSB (voltage) or +800LSB~+6,400LSB (current). When this value
under this range, the resolution of the input signal will be thin and the variation of value will be
larger. When this value exceeds this range, the resolution of input signal will be thick and the
variation of value will be smaller.
7. CR#30 is fault code. Please refer to the following chart.

Note: 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 factory
setting 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 check
code. (only for RTU mode) b15=0: ASCII mode. b15=1: RTU mode. Communication format: ASCII
mode is 7Bit, even bit, 1 stop bit (7,E,1). Communication format of RTU mode is 8Bit, even bit, 1
stop bit (8,E,1).
10. CR#33 is used to set the inner function priority. For example: characteristic register. Output
latched 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 to
read/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). Communication
format 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—write
many WORDs into register.

The chart above is to adjust A/D conversion characteristic curve of voltage input mode and current
input mode. Users can adjust conversion characteristic curve by changing OFFSET values
(CR#18~CR#21) and GAIN values (CR#24~CR#27) depend on application.

5 INSTALLATION & WIRING
1. Installation of the DIN rail
The 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-side
motion of the ELC, thus to reduce the chance of the wires being pulled loose. At the bottom of the
ELC is a small retaining clip. To secure the ELC to the DIN rail, place it onto the rail and gently push
up the clip.
To remove it, pull down the retaining clip and gently pull the
ELC away from the DIN rail. As shown on the right:
When installing the ELC, make sure that it is installed in an
enclosure with sufficient space (as shown on the right) to its
surroundings so as to allow heat dissipation.

Notes:
1. Please use 22-16AWG (1.5mm) wiring (either single or multiple
core) for I/O wiring terminals. The specification for the terminals is
as shown on the left. ELC terminal screws should be tightened to
1.95 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 same
multi-wire cable or conduit.
6INITIAL ELC START-UP
Lamp 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 the
power 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/A
LED should blink.
4. After receiving the first RS-485 command during controlling by RS-485, A/D LED or D/A
LED should blink.
5. After converting, ERROR LED should blink if input or output exceeds upper bound or
lower than lower bound.
