## **Extensive line-up with models to match application and space** 

2015.07 panasonic.net/id/pidsx/global | 

## **Upgraded models Features of KT4R, KT8R and KT9R** 

## **Smooth initial setting and setting adjustment** 

Operation startup can begin after using initial setting mode to enter the control values required before first use, and after entering values for items such as frequently used and frequently changed settings. Smooth operation is enabled at initial startup and after changing settings. 

## **Fine control of heat capacity** 

Sampling period rate half ([1] /2 times) from previous model: high speed 125 ms processing implemented. With twice the responsiveness, it is possible to more finely carry out control, for example, of the heat capacity. 

## **Built-in easy programming function** 

Easy programmed control made possible using nine-step setting procedure. By entering specific target values for each indicated period, freely selectable temperature control is possible. 

## **Example: From start of programmed control** 

-  Perform control so it becomes 200 °C 392 °F after 1 hour. 

## **Built-in rearing auto tuning function** 

The built-in rearing auto tuning function uses the step response method. From temperature rise behavior alone, it can calculate the PID constants. It is possible to calculate constants, even when auto tuning cannot be used to generate them. 

Because an ON / OFF operation is unnecessary, there is no disruption in control. 

-  Maintain 200 °C 392 °F until after 2 hours

## **Shared features of KT series** 

## **Multi-input sensors** 

Versatile thermocouple, RTD, DC voltage and DC current input for temperature detecting sensors 

## **Simple operation enables highly accurate temperature control** 

All required operations can be enabled by the front keys and highly accurate PID control mode ensures an input span of ±0.2 %. 

## **DIN Rail mounting types are aligned taking global market demand into consideration (for KT7 series)** 

## **Improved visibility and ease of operation More compact than before** 

The **KT4H / KT4B** series features improved visibility with a process value (PV) character height of 12 mm 0.472 in and an 11-segment display. Connectable to a PC, it offers a full range of control and communication functions. 

## **Communication specification uses RS485 (Modbus protocol)** 

**FPΣ** Programmable Controller 

The **KT7** series is equipped with DIN rail mounting complying to DIN standards. Furthermore, because its control panel is compact, the **KT7** series saves space. 

## **Nine step pattern control possible. (for KT2 series)**

RS485<br>**----- End of picture text -----**<br>


For **KT2** series, despite DIN 48 x 24 size, selection is possible of control with fixed set point and nine step pattern control. 

## **Meets market demands for cost-effectiveness** pT 

The **KT** series offers both economy and high performance. 

## **The KT series complies with UL/c-UL standard and CE marking.** 

Up to 31 units can be connected 

- *1 Only on type equipped with communications function. 

- *2 In the configuration above, the **FPΣ** requires a communication cassette ( **FPG-COM3** ). 

- *3 Modbus protocol is a communication protocol developed for PLCs by Modicon Inc.

Notes: 1)  Shielded cable 

To prevent current flow along shield sections, ground one end of the shield cable. (If both ends of the shield section are grounded, a closed circuit with the earth will form and electricity flowing through the shield cable will cause increased susceptibility to noise�) 

- 2)  Terminating Resistors (Terminators) The **KT4H / KT4B** series has a built-in pull-up resistor or pull-down resistor� For this reason, do not connect the terminating resistor on the communication line�

**KT SERIES Temperature Controller** 

## **NOTES FOR USE** 

## n **Notes on site selection** 

**This controller is intended to be used in the following environment (IEC 61010-1)** 

- **Overvoltage category II and Pollution degree 2 Mount the controller in a place with:** 

- **A minimum of dust, and an absence of corrosive gases** 

- **No flammable, explosive gases** 

- **Few mechanical vibrations or shocks** 

- **No exposure to direct sunlight, an ambient temperature of 0 to 50 °C 32 to 122 °F (For KT4R / KT8R / KT9R: -10 to 55 °C** 

- **14 to 131 °F) that does not change rapidly. (When installing inside a panel, make particular allowance for heat dissipation. Avoid installation in situations such as above equipment that generates heat.)** 

- **Locations in which temperature rapidly changes may cause condensation.** 

- **Locations or atmospheres in which benzine, thinners, alcohol, or other organic solvents are present, or in which ammonia, sodium hydroxide, or other strong alkaline substances may adhere.** 

- **Locations susceptible to direct impact or the transmission of vibrations, or where splashing with water is possible.** 

- **In the proximity of equipment in which large switching surges occur or near high-voltage cables, high-voltage equipment, power lines, power equipment, ham radio transmitters, or equipment containing these or similar devices.** 

- **In the case of 24 V AC / DC power supply, do not confuse the polarity when it is DC.** 

- **With the relay contact output type, use the relay externally according to the capacity of the load to protect the built-in relay contact.** 

- **When wiring, keep input wire (Thermocouple, RTD, etc.) away from power source wire and load wire.** 

- **Turn the power supply to the instrument off before wiring or checking. Working or touching the terminal with the power switched on may result in electric shock which could cause severe injury or death.** 

- **Do not drop wire chips into the holes of vent when wiring.** 

- **To prevent the controller from harmful effects of unexpected high level noise, it is recommended that a surge absorber be installed between the electromagnetic switch coils.** 

## n **Notes on mounting** 

   - **Do not use excessive force while screwing in the installation frame and mounting bracket of KT4R / KT8R / KT9R / KT4H / KT4B series. For KT8R / KT9R series, recommended torque is approximately 0.1 N·m. For KT4H / KT4B series, recommended torque is approximately 0.05 to 0.06 N·m. For KT4R series, recommended torque is approximately 0.15 N·m.** 

   - **When mounting the KT7 series to the DIN rail, mount it in a lateral direction. Make sure a click is audible when fixed into place.** 

- **An ambient non-condensing humidity of 35 to 85 % RH** 

- **No large capacity electromagnetic switches or cables through which large current is flowing** 

- **No water, oil or chemicals or where the vapors of these** 

**substances can come into direct contact with the controller** 

## n **Notes on wiring** 

- **The terminal block of KT4R / KT8R / KT9R / KT4H / KT4B series are designed to be wired from the left side (The terminal of KT2 series are designed to be wired from the upper and lower direction). The lead wire must be inserted from the left side of the terminal, and fastened by the terminal screw. Use a wirepressed terminal with insulation sleeve that fits to the M3 screw.**

- **Terminal screw fastening torque is 0.6 N·m to 1.0 N·m (for KT4R / KT8R / KT9R / KT4H / KT4B series). For KT7 series by M3 screw is less than 0.5 N·m and by M2 screw is less than 0.25 N·m respectively.** 

- **Use a thermocouple and compensating lead wire according to the sensor input specification of the controller.** 

- **Use a 3-wire system of RTD according to the sensor input specification of the controller.** 

- **This controller has no built-in power switch, circuit breaker and fuse.  Therefore, it is necessary to install them in the circuit near the external controller. (Recommended fuse: Time-lag fuse, rating voltage 250 V AC, rating current 2 A)** 

## n **Optional heater burnout alarm output (for KT7 / KT4H series)** 

- **This alarm output is not available for detecting heater current under phase control.** 

- **Use the current transformer (CT) provided, and pass one lead wire of the heater circuit into the hole of CT.** 

- **When wiring, keep CT wire away from power source wire and load wire to avoid external interference.** 

- **In three phase installations for KT4H series, ensure that R, S and T are each connected to a 2-line CT that connects with CT1** 

- **[** ⑬ **-** ⑭ **] and CT2 [** ⑭ **-** ⑮ **] terminals.**
