Volume / Reset key Information
Output limitation
setting
(PW.MAX)
Function which limits an output amount. Output 0% when volume is
positioned at min and output 100% when it is positioned at max.
•Default setting : 100% (max.)
•No correspondence when performing ON/OFF control
Over current
alarm setting
(O.C)
The current LED becomes ON immediately when input value is more
than the set value and if that value is maintained for more than 0.5
sec then alarm output will become ON.
•Default set value : 100 A
•Set range : 0~rated current (max value)
Soft start setting
ON the switch for the first time when using the inductive or capacitive
load, max value power will be supplied into the load which may
damage the load or destroy the power device. This setting increases
the load voltage gradually.
•Default setting: 0 (Set range: 0~50 sec)
•It is not operated with “0” setting
•No correspondence when performing ON/OFF control
▒ Phase control
AC power source has 50/60 ㎐ frequency and 1/2 cycle of 60 ㎐ frequency appears a value of 0 ~180 degree
in about 8.33 ㎳. Phase Control is a method that after inputting 1/2 cycle into AC power source, it proportionally
generates power between 0 ~ 180 degree in 8.33 ㎳ according to the control signal. Also, this method can be
fully adjusted according to the wave form of AC so that AC motors and other variety of electronic devices are
controlled easily.
This is a mode that is used when load contains a lot of inductance components such as coil. Max output
value is limited to 50 %.

•Set value displaying 7 segment LED : Display the set value when setting the parameter Also,
it displays the measured value which selected in the displaying mode during operation.
Name of each button Explanation
Mode button Enter into the manual mode and save the data
Incremental button Increase the set value
Decrement button Decrease the set value
Selecting button
Manual operation/auto operation selectable by pressing it for 2 sec
When performing manual operation, it varies an output amount by
pressing increment/decrement key disregarding the input signal
Press it for 2 sec again then it will save the setting and return to the
auto operation mode
Reset button System temporarily stops when alarm occurs.
Pressing this button will restore the setting
Over current
compensating volume
Compensate the current indicated value displayed in the displaying
unit (default setting: positioned in the middle)

Front Toggle Switch and reset key
Switch Information
Select whether users will use the external manual controlling volume which connected to the terminal
or the internal output limitation (PW.MAX)
•REMOTE : Selected when using the external volume connected to the terminal
•LOCAL : Selected when using the output limitation (PW.MAX) setting internal volume
Select whether users will use the control output (4-20 mA) of controller as input signal or not (use
volume)
•AUTO : Selected when using the control output (4-20 ㎃) of controller as input signal
•HAND : Not using the input signal (4-20㎃) (select the setting by volume)
Select the control action as RUN state or STOP state
•RUN : Selected when it is in the general control state
•STOP : Selected when stopping the control action temporarily (output OFF)
When using the RUN/STOP which operates by the external contact input (D.I), please select the
internal RUN/STOP toggle switch as STOP side
Control state becomes the hold state temporarily when alarm output is ON. Pressing the Reset key
after solving the problem will restore the setting.
