Press down the expansion hooks raised in step 2 to secure the unit. 3.3 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: 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. D D E L C D D>50mm 3.4 Input/Output points numbering order No matter how many points of MPU, the input of the first I/O extension unit will start from X20, output will start from Y20.

Extension unit 4 ELC-EX08NNDR will be used as 8 input points/8 output points, the higher part 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. 3.5 Wiring Notes: 22-16AWG <1.5mm 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). 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. 3.6 Input Point Wiring There are two types of DC type wiring: SINK and SOURCE, defined as follows: 4 IL05003004E.pdf SINK Mode SOURCE Mode +24V S/S 0V X0 X1 X2 +24V DC Power Supply S/S 0V X0 X1 X2 DC Power Supply Sink mode Source mode 3.7 AC Type Wiring Input Circuit Connection 110V AC Input Specifications 85~132VAC 50/60Hz COM X0 X1 Input voltage 85~132VAC 50~60Hz Input impedance 21Kohm/50Hz 18Kohm/60Hz Input current 6.2mA 110VAC/60Hz OFFON/ONOFF 80V 3.8mA/30V 1.7mA Response time 25ms Circuit isolation/Operation indication Photocoupler/LED On X2 ELC-12PCNNAR 3.8 Output Point Wiring The Relay Output Circuit Wiring 1 Do not use this terminal 2 Fuse 3 Reverse-current protection diode, *1 C0 Y0 C1 Y1 C2 Y2 Y3 MC2 5 9 2 8 3 Y4 Y5 4 External Mechanical Interlock*2 1 MC1 5 Emergency stop 2 7 MC1 5 MC2 4 7 6 6 Surge absorber(0.1uf capacitor+100~120ohm resistor, *3: 7 Inductive load 8 Incandescent lamp 10 9 DC power Supply 10 AC power Supply *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. 5 IL05003004E.pdf The Transistor Output Circuit Wiring 1 Do not use this terminal 2 Emergency Stop C0 Y0 C1 Y1 C2 Y2 Y3 MC2 5 7 Y4 Y5 3 Fuse 1 MC1 4 External Mechanical Interlock 5 DC Power Supply 6 8 MC1 3 MC2 6 4 2 6 Incandescent Lamp 7 Reverse-current protection diode, *1 9 3 8 Inductive load 9 Resistive 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 Unit mounting status Power supply Check input/Output terminals Description - Does the unit type match the device list during the design stage? - Are all of the units firmly attached? - 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. - 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. 6 IL05003004E.pdf 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. 7
