New

KT2

Temperature

Controller

Compact temperature

controller (DIN 48

24) that

can support pattern control

■

FEATURES

1. Nine step pattern control possible.

Despite DIN 48 x 24 size, selection is

possible of control with ﬁxed set point and

nine step pattern control.

2. Multi-input

Versatile thermocouple, RTD, DC voltage

and DC current input for temperature

detecting sensors.

3. 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%.

4. Adding in optional functions

(heating/cooling and communication

functions), 24 product types are

available.

5. KT series complies with UL, CSA

standards and CE marking.

6. Adopt RS485 and Modbus protocol

for communication speciﬁcation

* In the conﬁguration above, FP

∑

requires a

communication cassette (FPG-COM3).

* Modbus is a communication protocol

developed for PLCs by Modicon Inc.

PV/SV display (red): Indicates the input value and setting value. During setting mode, characters

and setting value of the setting item are indicated in turn.

MEMO/STEP display (green): Indicates memory number during fixed value control. Indicates step number

during program control.

PV indicator (red): Lights up when the input value (PV) is indicated.

SV indicator (green): Lights up when main setting value (SV) is indicated.

AT indicator (yellow): Flashes during AT (auto-tuning).

T/R indicator (yellow): Flashes during serial communication (Lit while sending data, Unlit while

receiving data)

OUT indicator (green): Lights up when control output or OUT1 (Heating side, option Heating/Cooling

control) is ON. (For DC current output type, it flashes corresponding to the

manipulated variable in a 0.25 second cycle)

EV1 indicator (red): Lights up when Event output 1 or OUT2 (Cooling side, option Heating/Cooling

control) is ON.

EV2 indicator (red): Lights up when Event output 2 is ON.

Increase key ( ): Increases the numeric value.

Decrease key ( ): Decreases the numeric value.

Mode key ( ): Selects the setting mode or registers the setting value.

(By pressing the Mode key, the setting value or selected value can be

registered)

OUT/OFF key ( ): The control output OUT/OFF or program control RUN/STOP can be switched.

KT(AKT2) ■ Setup procedures The setup procedures of this controller is shown below. Refer to each item for details. (1) Initial setting : Set the Input type, Alarm action, etc. during Auxiliary function setting mode 2. (If the users’ specification is the same as the default value of the KT2, initial setting is not necessary for the controller.) : Set Step SV and Step time for Program control during Main setting mode. (2) Main setting mode : Set PID values, A1 setting, etc during Sub setting mode.
