Explanation:
1. CR#0: The ELC model type.
2. CR#1: b11~b0 is used to set 4 inner channels working mode of analog input module (AD).
b12~b15 is used to set 2 channels working mode of analog output module (DA). 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 b0~b11 to H688. If setting CH5: mode 2 (b13~b12=10), CH6:
mode 1 (b15~b14=01), it needs to set b12~b15 to H5. The factory setting is H0000.
3. CR#2 ~ CR#5: Used to set the number of input readings used for the average temperature
calculation. The available range is K1~K100 and factory setting is K10.
4. CR#6 to CR#9: they are used to save the average value of input signal of CH1~CH4.
5. CR#10 ~ CR#11 are used to set the output value of CH5 and CH6. The setting range is
K0~K4,000. The factory setting is K0 and unit is LSB.
6. CR#12 ~ CR#15: they are used to save the present value of input signal of CH1~CH4.
7. CR#16, CR#17, CR#28, CR#29 are reserved.
8. 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(-1,000
LSB
~+1,000
LSB
). Current setting range: -20mA~+20mA (-1,000
LSB
~+1,000
LSB
).
9. CR #22~ CR #23: the content is the value of adjusting OFFSET value of CH5~CH6 if analog
input voltage or current is 0 after it transfers from analog to digital. The factory setting is K0 and
the unit is LSB. The setting range is -2,000~+2,000. Voltage setting range:
-5V~+5V(-2,000
LSB
~+2,000
LSB
). Current setting range: -10mA~+10mA (-2,000
LSB
~+2,000
LSB
).
10. CR #24~ CR #27: That is the value of adjust GAIN value of CH1~CH4. That is the value of
analog input voltage or current when conversion value from analog signal to digital is 4,000.
Voltage setting range: -4V~+20V(-800
LSB
~+4,000
LSB
). Current setting range: -16mA~+52mA
(-800
LSB
~+2,600
LSB
). But it needs to notice that GAIN VALUE – OFFSET VALUE =
+200
LSB
~+3,000
LSB
(voltage) or +200
LSB
~+1,600
LSB
(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.
11. CR #28~ CR #29: That is the value of adjust GAIN value of CH5~CH6. That is the value of
analog input voltage or current when conversion value from analog signal to digital is 2,000.
Voltage setting range: -4V~+20V(-1,600
LSB
~+8,000
LSB
). Current setting range: -8 mA ~+40 mA
(-1,600
LSB
~+8,000
LSB
). But it needs to notice that GAIN VALUE – OFFSET VALUE = +400
LSB
~+6,000
LSB
(voltage/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.

time. 0 means normal and 1 means having fault.

15. 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 loss power.

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.
