In the case of resa le, en sure th at this instrument is not illegally exported.

Precautions

1. Installation precautions

Caution

This instrument is intended to be used under the following environmental conditions (IEC61010-1): Overvoltage category Ensure the mounting location corresponds to the following conditions:

• A minimum of dust, and an absence of corrosive gases

• No flammable, explosive gases

• No mechanical vibrations or shocks

• No exposure to direct sunlight, an ambient temperature of 0 to 50 rapidly

• 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 unit

Note: Do not install this instrument near flammable material even though the case of this instrument is

made of flame resistant resin. Avoid setting this instrument directly on flammable material.

2. Wiring precautions

, Pollution degree 2

(32 to 122 ) that does not change

Caution

• Do not leave bits of wire in the instrument, because they could cause fire or malfunction.

• Use the solderless terminal with an insulation sleeve in which the M3 screw fits when wiring the KT4H.

• The terminal block of this instrument is designed to be wired from the left side.

The lead wire must be inserted from the left side of the terminal, and fastened with the terminal screw.

• When using a Terminal cover (AKT4H801), pass terminal wires numbered 7 to 12 into the holes of the

terminal cover. See (Fig. 3.4-2) on page 8.

• Tighten the terminal screw to within the specified torque. If excessive force is applied to the screw when tightening, the terminal screw or case may be damaged.

• This controller does not have a built-in power switch, circuit breaker or fuse. It is necessary to install

them near the controller.

(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)

• For a 24V AC/DC power source, do not confuse polarity when using direct current (DC).

• Do not apply a commercial power source to the sensor which is connected to the input terminal nor

allow the power source to come into contact with the sensor.

• Use a thermocou ple and compe nsating lea d wire according to the sensor input specificat ions of this controller.

• Use the 3-wire RTD according to the sensor input specifications of this controller.

• (+) side input terminal number of 0 to 5V DC, 1 to 5V DC, 0 to 10V DC differs from that of 0 to 1V DC.

(+) side input terminal number of 0 to 5V DC, 1 to 5V DC, 0 to 10V DC: 9 (+) side input terminal number of 0 to 1V DC: 10

• When using a relay contact output type, use a relay according to the capacity of the load to protect the built-in relay contact.

• When wiring, keep input wires (thermocouple, RTD, etc.) away from AC sources or load wires to avoid external interference.

3. Operation and maintenance precautions

Caution

• It is recommended that the PID auto-tuning be performed on the trial run.

• Do not touch live terminals. This may cause electric shock or problems in operation.

• Turn the power supply to the instrument OFF before retightening the terminal and cleaning. Working or touching the terminal with the power switched ON may result in severe injury or death due to Electric Shock.

• Use a soft, dry cloth when cleaning the instrument. (Alcohol based substances may deface or tarnish the unit.)

• As the display section is vulnerable, do not strike or scratch it with a hard object.

5.3 Wiring of Heater burnout alarm (Option: Single phase, 3-phase)

This alarm is not usable 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 the CT. (Fig. 5.3-1)

When wiring, keep the CT wire away from AC sources or load wires to avoid the external interference. In the case of 3-phase, pass any 2 lead wires of R, S, T into the CT, and connect them with CT1 (13, 14) and CT2 terminals (14, 15). (Fig. 5.3-2)

Heater burnout alarm 2 value setting

• Sets the heater current value for Heater burnout alarm 2. CT2 current value is indicated on the PV display.

When OUT1 is ON, the CT2 current value is updated. When OUT1 is OFF, the KT4H

memorizes the previous value when OUT1 was ON.

Setting to 0.0 disables the alarm. Upon returning to set limits, the alarm will stop. Available only when Heater burnout alarm option (3-phase) is added.

• Rated current: 20A (0.0 to 20.0A), 50A (0.0 to 50.0A)

6.7 Auxiliary function setting mode

To enter the Auxiliary function setting mode, press key in the PV/SV display mode.

To set or select each setting item, use Setting item numbers such as [17], [18], etc. are the same as those on the “6.4 Operation flowchart” (p.12).

Set value lock selection

• Locks the set values to prevent setting errors.

The setting item to be locked depends on the designation. If Lock 1 or Lock 2 is selected, PID Auto- tuning and Auto-reset cannot be carried out.

• (Lock 1): None of the set values can be changed. (Lock 2): Only main setting mode can be changed.

Sensor correction setting

• Sets the correction value for the sensor.

This corrects the input value from the sensor. When a sensor cannot be set at the exact location where control is desired, the sensor measured temperature may deviate from the temperature in the controlled location. When controlling with plural controllers, sometimes the measured temperatures (input value) do not concur with the same set value due to difference in sensor accuracy or dispersion of load capacities. In such a case, the control can be set at the desired temperature by adjusting the input value of sensors.

Communication protocol selection

• Selects the communication protocol. Not available if the Serial communication opt ion is not added, or if Contact input option is added.

• Sets the instrument number individually to each instrument when communicating by

connecting plural instruments.

Not available if Serial communication option is not added or if Contact input option is added.

• Setting range: 1 to 99

Communication speed selection

• Selects a communication speed equal to that of the host computer. Not available if Serial communication option is not added or if the Contact input option is

added.

•

(Unlock) : All set values can be changed.

(Lock 3): All set values can be changed. However, changed values revert to their

previous value after power is turned off because they are not saved in the non-volatile memory. (If the value set by the communication function is the same

as the value before the setting, the value will not be written in the non-volatile memory .)

Do not change any setting item in Setup mode. If any item in Setup mode is changed, it will affect other setting items such as the SV and Alarm value.
