• Follow instructions in ‘Cautions during Use’. Otherwise, it may cause unexpected accidents.
• Power supply should be insulated and limited voltage / current or Class 2, SELV power
supply device.
• Use the product, after 3 sec of supplying power.
• Before use, set the mode and function according to the specication. Since changing the
mode / parameter during operation may result in malfunction, set the mode and function
after disconnecting load output.
• Re-supply the power to the unit after 3 sec of turning o the power. Failure to follow this
instruction may result in malfunction.
• To ensure the reliability of the product, install the product on the panel or metal surface
vertically to the ground.
• Install the unit in the well ventilated place.
• While supplying power to the load or right after turning o 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.
• Install a power switch or circuit breaker in the easily accessible place for supplying or
disconnecting the power.
• Do not wire to terminals which are not used.
• Use twisted pair wire for communication line.
• When connecting the display module and the main body with a LAN cable (direct / cross
cable), be careful not to generate excessive tension. Poor contact may cause malfunction of
the display.
• Since inter element can be damaged when using with coil load, inductive load, etc., the
inrush current must be under the rated load current.
• To prevent product malfunction due to noise, wire power, control input, communication,
and load cables separately.
• When installing close to the load line, use a line lter for the power line and use a shield wire.
-|Transparent Guide|-
• For stable operation, use shield wire for control, alarm, and communication wires.
Use a ferrite core on the shield wire to cope with EMC.
• Do not use near the equipment which generates strong magnetic force or high frequency noise.
• This unit may be used in the following environments.
- Indoors (in the environment condition rated in ‘Specications’)
- Altitude max. 2,000 m
- Pollution degree 2
- Installation category III
• Press the display module removal button on the top of the unit.
• The separated display module is available to install on a remote
panel for convenient load monitoring.
• Connect the RJ45 cable between the display module and main
body. This cable should be within 5 m length for prevent noise.

Alarm
By setting parameters, you can set whether to use each alarm and relay output.
It can protect the load/fuse from overcurrent.
During alarm operation, OC in LINE1 ashes every 0.5 sec and the output stops (SCR
OFF).
• Operation condition: If the current higher than the LMT-C set value of the 2-1
overcurrent alarm is applied during the DLY-T set time of the 2-1 overcurrent alarm, an
alarm occurs. The set value is based on the RMS value.
It can protect the load from overvoltage.
During alarm operation, OV on LINE1 ashes every 0.5 sec and the output stops (SCR
OFF).
• Operation condition: If the voltage higher than the LMT-V set value of the 2-2
overvoltage alarm is applied during the DLY-T set time of the 2-2 overvoltage alarm,
an alarm occurs. The set value is based on the RMS value.
Heatsink over heat alarm
During alarm operation, OTW on LINE1 ashes every 0.5 sec and the output maintains.
• Operation condition: If the temperature of the heatsink maintains the temperature
above the TEMP set value of the 2-3 heatsink over heat alarm during the DLY-T set
time of the 2-3 heatsink over heat alarm, an alarm occurs.
During alarm operation, OTP on LINE1 ashes every 0.5 sec and the output stops (SCR
OFF).
• Operation condition: If the temperature of the heatsink maintains the temperature
above the TEMP set value of the 2-4 heatsink over heat protection alarm during the
DLY-T set time of the 2-4 heatsink over heat protection alarm, an alarm occurs.
Heater break alarm
During alarm operation, HT-BK on LINE1 ashes every 0.5 sec and the output stops (SCR
OFF).
• Operation condition: If the current below the LMT-C set value of the 2-5 heater break
alarm is over the LMT-O set output of the 2-5 heater break alarm during the DLY-T set
time of the 2-5 heater break alarm, an alarm occurs.
Partial heater break alarm
Partial heater break alarm is available for single phase control.
During alarm operation, DLF-A on LINE1 ashes every 0.5 sec and the output maintains.
• Operation condition: When using up to 6 parallel loads based on single-phase 1
channel, an alarm occurs if some loads (heaters) are disconnected.
An alarm occurs when the average current value of the load generated by scanning
the heater (load) is dierent from the currently measured average current value.
Load unbalance alarm
During alarm operation, UL on LINE1 ashes every 0.5 sec and the output maintains.
• Operation condition: If the unbalance rate over the LMT-P set value of the 2-7 load
unbalance alarm continues during the DLY-T set time of the 2-7 load imbalance alarm,
an alarm occurs.
• Unbalance rate (%) = (Max. line current - Min. line current) × 100
Average line current
E.g.) R-phase line current: 100 A, S-phase line current: 90 A, T-phase line current: 80 A,
Unbalance rate (%) = (100 - 80) × 100 = 22.22 %
90
SCR error alarm
During alarm operation, SCR-A on LINE1 ashes every 0.5 sec and the output stops (SCR
OFF).
• Operation condition: If the current over the LMT-C set value of the 2-8 SCR error alarm
is applied over the LMT-O set output of the 2-8 SCR error alarm during the DLY-T set
time of the 2-8 SCR error alarm, an alarm occurs.
Fuse break alarm
During alarm operation, FUSE on LINE1 ashes every 0.5 sec and the output stops (SCR
OFF).
• Operation condition: If the fuse break, load no-power, or load disconnection
continues during the DLY-T set time of the 2-9 fuse break alarm, an alarm occurs.
FAN error alarm
During alarm operation, FAN on LINE1 ashes every 0.5 sec and the output maintains.
• Operation condition: If the fan does not operate under the condition that the fan
should operate during the DLY-T set time of the 2-10 FAN error alarm, an alarm occurs.
• FAN operation condition: ON at heatsink (inner temperature) 40 ℃, OFF at 35 ℃
Frequency error alarm
During alarm operation, FRQY on LINE1 ashes every 0.5 sec and the output stops (SCR
OFF).
• Operation condition: If the power frequency of the load input remains out of 45 to 65
Hz during the DLY-T set time of the 2-11 frequency error alarm, an alarm occurs.

controlling the load (platinum. molybdenum, tungsten, infrared lamp, etc.) in which
inrush current ows when power is supplied, or showing large width of temperature
rise during initial operation.
If the input is changed before the end of the SOFT START function, T increases or

It is proper control method for a heater which

It outputs constant power which is proportion

• Output characteristics is proper 50 % of the
curve which connects the point (A) and the
point (B). The current output capacity of
this unit should be over two times of load
capacity.
Cycle control, zero cross turn-on
Compared to the phase control method, the load control linearity is better.
Since it is always ON or OFF at the zero point of AC, no noise is generated during ON /
OFF, so it is a suitable control method for an environment where noise is not aected or
an electric furnace with a large heat capacity.
•
During xed cycle (100 cycles) of load power, it repeats ON / OFF cycle as constant ratio
according to control input signal and controls the power supplies on the load.

• Variable cycle control mode
By optimizing the number of cycles of the load power, it controls the power applied to the load
by operating ON / OFF at a ratio proportional to the control input signal.
