Please read the following safety considerations before use.

Safety Considerations

00

Please observe all safety considerations for safe and proper product operation to avoid hazards.

※

symbol represents caution due to special circumstances in which hazards may occur.

※

Warning

Caution

Warning

1. Fail-safe device must be installed when using the unit with machinery that may cause
serious injury or substantial economic loss. (e.g. nuclear power control, medical equipment,
ships, vehicles, railways, aircraft, combustion apparatus, safety equipment, crime/disaster
prevention devices, etc.)

Failure to follow this instruction may result in re, personal injury, or economic loss.

2. Install on the device panel, and ground to the bolt for grounding separately.

Failure to follow this instruction may result in electric shock or re.

3. Do not connect, repair, or inspect the unit while connected to a power source.

Failure to follow this instruction may result in electric shock or re.

4. Check 'Connections' before wiring.

Failure to follow this instruction may result in re.

5. Do not disassemble or modify the unit.

Failure to follow this instruction may result in electric shock or re.

Caution

1. Use the unit within the rated specications.

Failure to follow this instruction may result in re or product damage.

2. Use dry cloth to clean the unit, and do not use water or organic solvent.

Failure to follow this instruction may result in electric shock or re.

3. Do not use the unit in the place where ammable/explosive/corrosive gas, humidity, direct

sunlight, radiant heat, vibration, impact, or salinity may be present.

Failure to follow this instruction may result in re or explosion.

4. Keep metal chip, dust, and wire residue from owing into the unit.

Failure to follow this instruction may result in re or product damage.

5. Since leakage current still ows right after turning off the power or in the output OFF status,

do not touch the load terminal.
Failure to follow this instruction may result in electric shock.

When the power is supplied, this function is able to

protect the load when it controls load (molybdan,
white gold, infrared lamp) with inrush current or the
width of rising temperature in big (SV is big).
SOFT START set time (T) is the required time that
output reaches to 100%, and it is differentiated by
OUT ADJ set value.

※

This function can not be used for ON/OFF control method.

SOFT UP/DOWN [

Unlike SOFT START which operates only once at
supplying power, this function protects load from the

PA

inrush current in the RUN mode. When reached to
the target output value, operation stops.

※

This function can not be used for ON/OFF control method.

Input correction [

It compensates the offset between actual input value
and measured input value.

RUN/STOP switching

RUN/STOP status of the power controller can be switched with the external
RUN/STOP contact.
In the RUN mode, the operation indicator on the front turns on.

AUTO/MANUAL selection

Operation mode (auto control/manual control) of the power controller can be
selected with the external AUTO/MAN contact.
In the manual control mode, the manual control indicator on the front turns on.

When multiple alarms occur at the same time, the highest priority error message will be displayed
based on priority.

1) SCR error alarm

Even though output is 0%, if the current of 10% or more of the rated load current ows for over 3 sec

continuously, SCR error alarm occurs.

2) Overcurrent alarm

This function protects the load from overcurrent.

If the current ows over the overcurrent alarm setting value [

overcurrent alarm occurs.

3) Heatsink overheat alarm

When the temperature of a heatsink is over 85℃, heatsink overheat alarm occurs.

4) Overvoltage alarm

This function protects the load from overvoltage.

If the current ows over the overvoltage alarm setting value [

overvoltage alarm occurs.

5) Heater break alarm

Comparing the full load resistance value and the current load resistance value, if the current load
resistivity is maintained under the setting value [
occurs. This alarm operates when control output is over 10% and load current is over 10% of the rated
current. Output does not stop and operates normally.

1. Follow instructions in 'Cautions during Use'. Otherwise, it may cause unexpected accidents.

2. Use the product, after 3 sec of supplying power.

3. Before use, set the mode and function according to the specification. Especially, be cautious that the
product does not operate when OUT ADJ. is set to 0%. Since changing the mode/parameter during
operation may result in malfunction, set the mode and function after disconnecting load output.

4. Re-supply the power to the unit after the unit is discharged completely.
Failure to follow this instruction may result in malfunction.

5. To ensure the reliability of the product, install the product on the panel or metal surface vertically to
the ground.

6. Install the unit in the well ventilated place.

7. While supplying power to the load or right after turning off the power of the load, do not touch
the body and heat sink. Failure to follow this instruction may result in a burn due to the high
temperature.

8. Install a power switch or circuit breaker in the easily accessible place for supplying or disconnecting
the power.

9. Do not wire to terminals which are not used.

10. Since inter element can be damaged when using with coil load, inductive load, etc., the inrush

current must be under the rated load current.

11. Do not use near the equipment which generates strong magnetic force or high frequency noise.

12. This unit may be used in the following environments.

①

Indoors (in the environment condition rated in 'Specifications')

②

Altitude max. 2,000m

③

Pollution degree 2

④
