POWER SUPPLY MODULE
WARNING
This instruction will be helpful in the installation, electronic specification, function specification and troubleshooting
of the ELC-PS01 and ELC-PS02.
This is an OPEN TYPE ELC-PS series.
The ELC-PS series should be kept in an enclosure away from airborne
dust, high 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-PS
series.
Never connect the AC main circuit power supply to any of the output terminals, as it will damage the ELC-PS series.
Check all the wiring prior to power up. To avoid any electromagnetic noise, make sure the ELC-PS series is
properly grounded
.
The power supply of ELC-PS series is only for ELC series, NOT for any other special instruments.

INSTALLATION AND WIRING
▪ Installation of the DIN rail
The power module can be secured to a cabinet by using the DIN rail that is 35mm high with a depth of 7.5mm. When
mounting the power module on the DIN rail, be sure to use the end bracket to stop any side-to-side motion of the power
module, thus to reduce the chance of the wires being pulled loose. At the bottom of the power module is a small
retaining clip.
To secure the power module 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 power module
away from the DIN rail. As shown on the right:

When installing the power module, 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.

▪ Wiring
1.
Please use O-type or Y-type terminals for I/O wiring terminals. The specification for
Below 6.2
the terminals is as shown on the right. Use Copper Conductor Only, 60 °C.
2.
Tighten PLC terminal screws to a torque of 5 to 8 kg-cm (4.3~6.9 in-lbs).
To suit M3.5 screw terminals
Below 6.2
NOTICE:
1.
Connect the AC input (100VAC ~ 240VAC) to terminals L and N. Any AC110V or AC220V connected to the +24V
terminal will permanently damage the ELC-PS01/PS02.
2.
Please use wires of 1.6mm and above for the grounding.
3.
If the power-cut time is less than 10ms, the ELC-PS01/PS02 still operates unaffectedly. If the power-cut time is too
long, the ELC-PS01/PS02 will stop operating and all the outputs will be Off.
TRIAL RUN
After wiring, be sure the check the items before turning ON the AC power to the ELC-PS01/02
- 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.
Turning ON the AC power, check the “POWER” LED(it will lit in green)
TROUBLESHOOTING
1. “POWER” LED is 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.
-
If the “POWER” LED remains OFF when disconnecting all the power supply wiring devices, there is probably an
abnormality in the power module internal circuit. Please contact your dealer.
2. “POWER” LED is Blinking
-
Reducing the power supply wiring device.. If the LED turn ON at this moment, the capacity of the power supply is
not enough. Prepare another power supply for other devices or increase the capacity of the power supply.
