Function description
▒ Phase control
Phase control is to control the AC power supply applied to the load proportionally according to the control
input signal as changing phase angle (0 ~ 180 degree) in a each half cycle, 8.33 ms.

▒ Fixed cycle control
As setting the constant cycle of the
output, (1 sec), fixed cycle control is
to control the AC power supply
repeatedly with a constant rate of
ON/OFF according to the control
input.
▒ ON/OFF control
▒ Restart function
▒ V.R Explanation
If ON/OFF contact is ON, then the output is 100 %. ON/OFF always operates near zero point.
When a warning or caution alarm occurs, TPR gives alarm 1 or 2 or stop the output. This function is used
to return to normal operation mode when factors caused errors are eliminated.
This function is able to set up when Fuse/Power Supply is in disorder, Heat sink over heat, SCR Short is
occurred. (When Overcurrent is occurred, this function is not working)
1. O.C (overcurrent setting function)
When overcurrent occurs, protection function for TPR and load (Only for phase control)
• V.R gradation for overcurrent setting position.
•Depending on load type and VR error, overcurrent
setting position can be different.
•
The overcurrent setting can be different depending on the
types of load or VR tolerance. In order to set an accurate
position of the overcurrent setting, adjust the control signal
that TPR can have the current that needs to be alarmed.
Turn the O.C VR until the O.C indicator is ON. The position of the O.C VR is the overcurrent setting value.
•If OC V.R turning to the right of the maximum, overcurrent function does not work.
2. SOFT
This volume is to set time for Soft start or Soft up/down. (only applicable to phase control, ON/OFF control)
- Soft start : Protection functions against big load of start current (inrush current). It increases output softly.
When control input is applied and power is on, Soft start operates when rung signal is applied.
In case of maximum VR, it set 50 second. (Example : 20 mA : 50 sec, 12 mA : 25 sec)
- Soft up / down : When run signal and power are applied and if control input is applied, it will operate. It
case of maximum VR, it set 10 second.
- If VR turn up to the right, the function does not work. And if VR turn right, time will be reduced.
3. POWER (output limit function)
This function is to limit the output regardless of
the control input amount. Even though the control
input is 100 %, the output will decrease as turning
POWER volume counterclockwise.
•Even though the control input signal is
ON, the output is 100 % when ON/OFF
control is used.

1. Please install it perpendicularly. If the product is installed vertically in
unavoidable circumstances, please use 50 % of rated current.
2. When multiple products are closely installed, please install them with
keeping a distance of more than a width of 5 cm and a length of
10 cm as shown in the picture.
3. In order to not block the air flow, please install the wiring duct less
than the half of the heat sink height.
4. Please consider whether the air flow is good enough when installing
the product. If the ambient temperature is as low as possible in the
inside then the life span of the product is increasing as the durability
and reliability of the product are improving. The operating ambient
temperature is 0 ℃ ~ 40 ℃. Please refer to the following graph.
However, if the ambient temperature is higher than 40 ℃, the
maximum load current is decreasing like the below.
5. When wiring, please use crimp connectors to high current flows terminal. If the contact surface of the
connectors and terminals are poor, it may lead to a fire since the wires and terminal gets overheated
6. Before applying power, this model need more than the third class grounding to prevent electric shock.
This model does not have separate grounding terminal so we suggest using grounding terminal and
bracket together when install this model to a panel.

▒ Variable cycle control
Without setting a constant cycle,
variable cycle control is to control
AC power supply with using the
number of cycle.

Description
POWER POWER indicator is ON when the power is being supplied to the control unit
FIRE Fire indicator is ON proportionally to the control input. It lights longer if the output amount is
large and it is continuously ON if it outputs 100 % continuously.
SOFT
To use Soft start, Soft up/down function, turn Soft VR clockwise and SOFT indicator will be ON.
O.C
If the current flows higher than set value of O.C volume when there is overcurrent then O.C indicator
is ON, the TPR stops the output to protect the product and the load and alarm 1 is activated.
L.L
When Load disconnected : In a situation where output is over 10 %, if load current is not
founded, alarm rings.
When Load Unbalanced : In a situation where output is over 10 %, if the load unbalance
between phases is over 4 A, the alarm rings
O.T When Heat sink temperature rise over 85 ℃’, it light up. Alarm 2 output will be out but TPR
operates without stop. And when temperature go down under 75 ℃, alarm will be off.
FUSE
When inner fuse is disconnected, When load power is not connected, In a situation where
circuit power supply (100 - 240 V AC) is connected, if any one phase of load power supply is
not working or inner part of FUSE is disconnected, alarm output ALARM1 rings.
SCR When inner part of SCR is short, the heater will keep overheating. So current flows to any
one-phase without control input, the light up.
