3.1. System Assembly
Procedure:
1. Open the extension cover on the side of
the unit with a screw driver so that the
external connector is exposed.
2. Raise the extension hooks on the top
and bottom sides of the unit with a
screwdriver.
3. Align the pins and holes in the four
corners of the control unit and extension
unit, and insert the pins into the holes
so that there is no gap between the
units.
4. Press down the expansion hooks raised
in step 2 to secure the unit.
3.2. 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 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.

numbers of inputs points and output points have no corresponding input/output points. It is
recommended to place them at the end of serial wiring, so that I/O points numbering will be
continuous.
3.4. Wiring
22-16AWG
<1.5mm
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-n). 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.

*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.
4 TRIAL RUN
4.1. Before Turning ON the Power
After wiring, be sure to check the items below before turning ON the power supply to the ELC.
Item Description
Unit mounting status -Does the unit type match the device list during the design stage?
-Are all of the units firmly attached?
Power supply -Is operating voltage supplied correctly?
-Is the power supply cable properly connected?
-Are both voltage and polarity connected correctly for each connection
-Protection against excess current: when overloaded, output voltage lowers.
Although the output voltage will return to normal when the load returns to normal,
be careful as long overloads or short-circuits will cause deterioration or destruction
of internal elements.
-Attaching additional power supply units in parallel is not allowed! It may destroy
internal elements and the load of the power supply.
Check input/Output
terminals
-Does the wiring of connector and terminal match?
-Is the operating voltage of I/O correct?
-Are the connectors of I/O properly connected?
-Is the wire size correct?
Note: These precautions concern the ELC-PS01/PS02 power supply unit specifically.

4.2. Turning the Power ON
After checking the items given on the section 7.1, perform the trial operation by adhering to the
following procedure.
-Check “POWER” LED at the front of the ELC extension unit.
-Check “LV” LED at the front of the ELC extension unit.
4.3. Check Communication with ELC control unit
After Power on and ELC is completing initial setup. The total number of extensive input/output points
will be stored in special data registers of D1142 and D1143.
Please check D1142 and D1143 to confirm the adding extension unit is connecting with control unit
normally.
5 TROUBLESHOOTING
5.1. All LEDs are OFF
-Check the power supply wiring.
-Check if the power supplied to the ELC control units is in the range of the rating.
Be sure to check the fluctuation in the power supply.
-Disconnect the power supply wiring to the other devices if the power supplied to the ELC
control unit is shared with them.
If the LEDs on the ELC control unit turn ON at this moment, the capacity of the power supply
is not enough to control other devices as well. Prepare another power supply for other devices
or increase the capacity of the power supply.
5.2. Diagnosing Input Malfunction
-Check the wiring of the input devices(input indicator LEDs are OFF)
-Check that the power is properly supplied to the input terminals.
If the power is properly supplied to the input terminal, there is probably an abnormality in
the ELC’s input circuit. Please contact your dealer.
If the power is not properly supplied to the input terminal, there is probably an abnormality
in the input device or input power supply. Check the input device and input power supply.
-Check the input condition (input indicator LEDs are ON)
-Monitor the input condition using a programming tool.
If the input monitored is OFF, there is probably an abnormality in the ELC’s input circuit.
Please contact your dealer.
If the input monitored is ON, check the program again. Also, check the leakage current at
the input devices (e.g., two-wire sensor) and check for the duplicated use of output or the
program flow when a control instruction such as MC or CJ is used.
Check the settings of the I/O allocation.
5.3. Diagnosing Output Malfunction
-Check the wiring of the loads. (output indicator LEDs are ON)
-Check if the power is properly supplied to the loads.
If the power is properly supplied to the load, there is probably an abnormality in the load.
Check the load again. If the power is not supplied to the load, there is probably an
abnormality in the ELC’s output circuit. Pleas contact your dealer.
-Check of output condition (output indicator LEDs are OFF)
-Monitor the output condition using a programming tool.
If the output monitored is turned ON, there is probably a duplicated output error.
-Forcing ON the output using a programming tool.
If the output indicator LED is turned ON, go to input condition check.
If the output LED remains OFF, there is probably an abnormality in the ELC’s output circuit.
Please contact your dealer.
