█ Phase control
50 % Output 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.

Without setting a constant cycle, variable cycle control is to control AC power supply with

█ ON/OFF control
If ON/OFF contact is ON, then the output is 100 %. ON/OFF always operates near zero point.

Checking list
1. Confirmation of load power voltage for each channel
(Example: Check 1CH load voltage when 1CH POWER Fail)
2. Check that the load power breaker is ON (Reset, turn on / off)
3. SCR load power input terminal R, S, T wiring check
1. Open the upper case of SCR and check the fuse disconnection
(Shot is normal when measuring the fuse tester after the load
power is turned off)
1. Check the resistance value of the load connected to the SCR
(disconnection and disconnection)
2. Check the SCR heater connection terminals U, V, W wiring
1. Symptom: When 4 mA and control input are not applied, load
current When more than 5 A flows.
2. Confirm: Check several channel SCR Short
3. Generation channel 4 - 20 mA Input part voltage is less than
0.4 V, Ensure current is measured in clampmeter
(SCR failure if confirmed, replacement required)
1. When the current exceeding the OC Limit setting value flows to the load
2. Clamp meter connected to overcurrent identified channels U, V, W Check
the current on the wiring
1. Make sure that the cooling fan on the bottom of the SCR is rotating
80 % OFF
2. Make sure that there is foreign substance in the cooling fan
1. Check if the heater value is saved using the Scan function (communication)
2. If you do not know whether or not you have scanned the control signal (4 - 20 mA)
When there is no scan, DIP SW 2 turns OFF and scan progress, LL LED
When it changes to flashing, it changes to switch ON position again. 20 % OFF
3. Check the resistance value of the heater. Comparison of the resistance value of the
part (When the resistance value becomes high,
1. Check if cooling fan is rotating well
2. Identify the cooling unit inside the panel
3. If an alarm occurs immediately upon power-on,

█ Restart function
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.
█ O.C (overcurrent setting function)
When overcurrent occurs, protection function for TPR and load (Only for phase control)
█ POWER (output limit function)
This function is to limit the output regardless of the control input amount.
Can be set by communication - Even though the control input is 100 %
█ V.R Explanation
•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).
- Soft up / down : When run signal and power are applied and if control input is applied,
- If VR turn up to the right, the function does not work. And if VR turn right, time will be reduced.
Installation
100 % Control
Perpendicular installation
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.

VR setting value (%)
Control input (%)
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)
it will operate. It case of maximum VR, it set 10 second.

Airflow
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
