INSTALLATION & WIRING
3.1 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:
D
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.

3.2 Wiring
Notes:
22-16AWG
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 in-lbs).
<1.5mm
2. I/O signal wires or power supply should not run through the same multi-wire cable or
conduit.
3. DO NOT store the ELC in an atmosphere that is dusty, smoky, with metallic debris or
corrosive or flammable gases or high temperature or high humidity.
4. DO NOT install the ELC on a shelf or on an unstable surface.
3.3 Power Input Wiring
1.
When DC voltage is supplied to the ELC, make sure the power is at terminals 24VDC and 0V (power range is
20.4VDC~28.8VDC). When voltage is lower than 20.4VDC, ELC will stop operating, all outputs will turn OFF and the
ERROR LED will flash continuously.
2.
If the power-cut time is less than 10ms, the ELC still operates unaffectedly. If the power-cut time is too long or the power
voltage drops, the ELC will stop operating and all the outputs will be Off. Once the power is restored, the ELC will return to
operate automatically. (There are latched auxiliary relays and registers inside of the ELC, please be aware when
programming.)

3.4 Safety Guidelines
Since the ELC is in control of numerous devices, motion of either one device could affect the motion of other devices, and the
breakdown of either one device would consequently be detrimental to the whole auto control system, and danger will thus be
resulted. What follow is the recommended wiring for the power input:

Overload Capacity of the Output Terminal
Every output contact possesses the overload capacity that is twice the rated current within 5 minutes, and as for the common
contact, the overload capacity is 1.5 times the rated current within 2 minutes. And if the range is exceeded, it might result in the
contact’s malfunctioning, or even cause internal wire burnt.
5
IL05003011E.pdf
There are two types of output modules for the ELC: the relay and the transistor. Refer to Functions & Specifications for
relevant electric specifications.
When actual wiring is conducted at the output terminal, pay special attention to the wiring at the common end. Take
ELC-PB14NNDR as an example, the output terminal Y0 utilizes the common end C0, and Y2 uses C1, whereas Y2~Y5 use
C2.
Isolation Circuit: the photocoupler is utilized as the signal isolation between the internal circuit of the ELC and input module.

*1: This ELC does not have any internal protection circuitry on the relay outputs. For switching direct current on inductive loads,
a reverse-current protection diode should be installed in parallel with the load. The relay contact life decreases significantly
if this is not done.
The reverse-current protection diode needs to satisfy the following specifications.
The diode is rated for maximum reverse voltage of 5~10+ times the load voltage.
The forward current is more that the load current
*2: Ensure all loads are applied to the same side of each ELC output, see above figure. Loads which should never
simultaneously operate(e.g. direction control of a motor), because of a critical safety situation, should not rely on the ELC’s
sequencing alone. Mechanical interlocks must be fitted to all critical safety circuits.
*3: This ELC does not have any internal protection circuitry on the relay output. For switching AC on inductive loads, a surge
absorber (0.1uF+ “100ohm to 120ohm”) should be installed in parallel with the load. The relay contat life decreases
significantly if this is not done. Besides protecting the internal circuity of the ELC, a surge absorber decreases the noise
emissions to the load.

*1: Ensure all loads are applied to the same side of each ELC output, see above figure. Loads which should never
simutaneously operate (e.g. direction control of a motor), because of a critical safety situation, should not rely on the ELC’s
sequencing alone. Mechanical interlocks must be fitted to all critical safety circuits.
*2: Transistor outputs use internal zener diode(39V) as protection circuitry. When driving the inductive load with transistor
output, a reverse-current protection diode can be installed in parallel with the load if necessary.
The reverse-current protection diode needs to satisfy the following specifications.
The diode is rated for maximum reverse voltage of 5 to 10+ times the load voltage.
The forward current is more than the load current.

TRIAL RUN
Power Indication
The “POWER” LED at the front of the ELC will be lit (in green) if the power is on.
Preparation
1.
Prior to applying power, please verify that the power lines and the input/output wiring are correct.
And be advised not to
supply AC110V or AC220V into the I/O terminals, or it might short-circuit the wiring and would cause direct damage to the
ELC.
2.
After using the peripheral devices to write the program into the ELC and that the ERROR LED of the ELC is not on, it
means that the program in use is legitimate, and it is now waiting for the user to give the RUN command.
3.
Use ELC-HHP to execute the forced On/Off test of the output contact.
Operation & Test
If the “ERROR” LED of the ELC is not blinking, use RUN/STOP switch or the peripheral devices (ELC-HHP or ELCSoft) to give
the RUN command, and the RUN indicator will then be on.
If the “RUN” LED is not on, it indicates that there is no program
inside the ELC.
ELC-HHP could be utilized to monitor the settings and the registered values of the timer (T), the counter (C) and the data
register (D) during operation, and moreover, to force the output contacts to conduct the On/Off action.
If the ERROR LED is
on (but not blinking), it means that the setting of the user’s program has exceeded the preset overtime limit, thus users have to
double check the program and perform the On/Off function again. (The ELC is at this moment back to STOP automatically)
ELC Input/Output Reaction Time
The total reaction time from the input signal to the output operation is calculated as follows:
Reaction Time = input delay time + program scan time + output delay time
Input delay time
10ms (factory default), 0~15ms adjustable.
Refer to the usage of special register D1020.
Program scan time
Please refer to the usage of special register D1010.
Output delay time
Relay module: 10ms. Transistor module: 20~30us.
Basic Commands and Application Commands of the ELC:
1.
The basic commands and the application commands of the ELC of this series are totally applicable to the ELC. Refer to
the ELC Technique Application Manual for relevant basic commands and application commands.
2.
The ELC-HHP handheld programming panel and the ELCSoft editing program of the ladder diagram are both good for
use with the ELC.
Also, the ELC could connect with the ELC-PB14NNDR/T through specific transmission wire to
execute the program transmission, the ELC control and the program monitoring.

TROUBLESHOOTING
Judge the errors by the indicators on the front panel. When errors occurred on ELC, please check:
☼
“POWER” LED
There is a “POWER” LED at the front of the ELC. When the ELC is powered On, the green LED light will be on. If the indicator
is not on when the ELC is powered up and with the input power being normal, it is an indication that the ELC is out of order.
Please have this machine replaced or have it repaired at a dealer near you.
☼
ELC “RUN” LED
Identify the status of the ELC. When the ELC is in operation, this light will be on, and users could thus use ELC-HHP or the
editing program of the ladder diagram to give commands to make the ELC “RUN” or “STOP”.
☼
“ERROR” LED
If incorrect programs are input to the ELC, or that the commands and the components exceed the allowable range, the
indicator will blink. At this moment, the user should check both the error codes saved in the ELC data register D1004.
The
address that the error occurs will be stored in data register D1137 (the address saved in D1137 is invalid in case of common
loop error).
When the ERROR LED is on (not blinking), users should make a judgment from the special relay M1008 of the ELC. If it is On,
it indicates that the execution time of the program loop has exceeded the time-out setting (set by D1000). Please turn the ELC
RUN/STOP switch to STOP, and find out the address of the time-out program by special data register D1008. ”WDT”
command can be used to solve the problem.
☼
“Input” LED
The On/Off signals of the input point could be displayed through the “Input” LED, or the status of the input point could be
monitored through the device monitoring function of ELC-HHP.
☼
“Output” LED
Output LED indicates if the output signals are On or Off. Please check the following items when the LED On/Off indication
does not correspond to the commands: 1. Output contacts may be melted and stuck together due to a short circuit or current
overload. 2. Check wiring and verify that the screws are tight.
