Connection diagram of load terminal

• Inside of TPR, the fuse is installed in the R,S,T input power supply portion depending on the specification of options
• When connecting terminals, please use crimp connectors and securely fasten them due to the high current flow. (Max space for solder less terminal connection is 40/55/70 A: 16 mm, 90/130 A : 26 mm)
• Only one channel can be used per temperature controller. (Serial connection disabled)
• Since the internal GND is not separated, use a module or temperature controller that has separate analog inputs for each channel.

• NO. 1,2: RS485 Communication connection port
• NO.3,4:Channel 14-20 mA d.c. input
• NO.5,6:Channel 2 4-20 mA d.c. input
• NO.7,8:Channel 34-20 mA d.c. input
• NO.9,10:Alarm1 caution
  • “caution” The alarm is not a serious problem, but it is an alarm that needs to be checked by the user due to abnormal symptoms. At this time, the TPR output will go out to normal and only the alarm will be output.
  • Caution error: partial load disconnection, heat sink overheat (60 °C), Overcurrent, power failure, fuse disconnection, FAN error
• NO. 11, 12: Alarm2 warning
  • If a “Warning” alarm can cause damage to the product and the load, a warning will be issued in the following emergency situations. At this time, the TPR will stop the output itself.
  • Warning error: Heat sink overheat (80 °C), SCR conduction (Short)
  • Once it enters the normal state by supplies of circuit power ( 100 240 Va.c.) and load power, the alarm relay is short-circuited and it is opended when alarm occurs. (“B” contact normally close) In case of using “A” contact, inquire separately
  • If an alarm condition occurs, an alarm is output after 3 seconds, and if the alarm condition is released within 3 seconds, an alarm No output.

Function descriptions

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, fixed cycle control is to control the AC power supply repeatedly with a constant rate of ON/OFF according to the control input.

Variable cycle control

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

Restart function

• When a warning or caution alarm occurs, TPR gives alarmlor2 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)

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 poweris 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.

• 0.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 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 1Ocm 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 040 °C.
   Please refer to the following graph. However, if the ambient temperature is higher than 40 °C, 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 ternminal and bracket together when install this model to a panel.

7. Tighten the screws of the terminal block with the specified torque.
   M3.5: 0.6~1.2 N.m /M6:4.414.9 N.m M8:8.82~9.80 N.m

Communication

1. Communication method : RS485 2-wire half-duplex
2. Communication speed: 2400, 4800, 9600, 19200 bps

• When communication setting is changed, the change is applied after reset.

Communication protocol selection
Set the communication protocol with DIP S/W no. 8

Communication speed setting
Set the communication speed with DIP S/W no. 6 or 7

Communication setting (ModBus RTU/ASC II)

• 200: If it is 1, the status is being scanned. 0 is displayed after scanning is completed (3 channels are scanned at the same time)
• 201: Control method setting status being scanned
• 202: If it is 1, the scan is completed and the heater value is stored in the internal storage device (lIf it is 0, it is not saved, not scanned)
