■ VR Explanation
● SOFT
This is the function to set the soft start and soft up/down times.
(Set via external VR)
- Soft start : It is a function to protect against load with large starting current
(inrush current) and it gradually increases output operates when power is
turned on while control input is applied, and is set to 50 seconds at
maximum VR. (ex : 20 mA : 50 seconds,, 12 mA : 25 seconds,)
- If VR is set to the minimum, this function does not work, and the time is
reduced as VR is changed to the left.
■ O.C
Function to protect power regulator (TPR) and load when overcurrent occurs.
(Phase control only)
- At the time of shipment, it is set to about 120 % of the product rating, and the
overcurrent detection setting value can be changed through communication.
■ Output limit function
It is a function to limit the output separately from the control input signal. It
can be set through communication and the maximum output amount is
limited according to the set value.
- Set to 100 % at the time of shipment
▍ Installation
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 5cm and a length of 10cm 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 connecting R and U, please securely fasten them with using crimp connectors since high current
flows into these terminals. 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.
▍ Communication
1. Communication method : RS485 2－wire half-duplex
2. Communication speed : 2400, 4800, 9600, 19200 bps
3. Maximum number of connections : 31
4. Protocol : ModBus RTU, ModBus ASCII
■ Address (ID) setting

Explanation about SCR Alarm
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
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.
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, the SCR internal fault.
