1. Installation precautions

Caution

This instrument is intended to be used under the following environmental conditions (IEC61010-1): Overvoltage category , Pollution degree 2

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 (32 to 122) that does not change 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

Caution

•Use the solderless terminal with an insulation sleeve that fits in the M3 screw when wiring the KT9 Series.

•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.

•Tighten the terminal screw within the specified torque.

If excessive force is applied to the screw when tightening, the terminal screw or case may be damaged.

•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.

•This controller does not have 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).

3. Running and maintenance precautions

Warning

•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 tarnish or deface the unit)

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

However, this function can be switched only in the PV/SV display mode.

Notice

When setting the specifications and functions of this controller, connect terminals 2 and 3 for power source first, then set them referring to “5. Setup” before performing “3. Mounting to the control panel” and “4. Wiring”.

3.5 Mounting

Notice

As the case is made of resin, do not use excessive force while screwing in the mounting bracket, or the case or screw type mounting bracket could be damaged. The torque is approximately 0.12N•m.

Mount the controller vertically to the flat, rigid panel to ensure it adheres to the Dust-proof/Drip-proof specification (IP66).

Mounting panel thickness: 1 to 15mm.

Insert the instrument from the front side of the panel.

Attach the mounting bracket by the holes at the top and bottom of the case and secure in place with the screws.

•The terminal block of KT9 series 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.

•Dotted lines show options.

•If A2 (option) and Heater burnout alarm (option) are applied together, use terminals 12-13 for A2, and 9-10 for the Heater burnout alarm.

•If the Heating/Cooling control (option) and Heater burnout alarm (option) are applied together, use terminals 9-10 for the Heating/Cooling control, and 12-13 for the Heater burnout alarm.

4.2 Wiring examples

Notice

•Use a thermocouple and compensating lead wire according to the sensor input specifications of this controller.

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

•This controller does not have built-in power switch, circuit breaker or fuse. It is necessary to install them in the circuit near the external 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).

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

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

•Use a thick wire (1.25 to 2.0mm2) for grounding.

5. Setup

For the thermocouple and RTD input, the sensor input characters and temperature unit are indicated on the PV display and the input range high limit value is indicated on the SV display for approx. 3 seconds after the power is turned on. See (Table 5-1).

For DC input, the sensor input characters are indicated on the PV display and the scaling high limit value is indicated on the SV display. See (Table 5-1).

If any other value is set during the scaling high limit setting, the set value is indicated on the SV display.

During this time, all outputs and the LED indicators are in OFF status.

Control will then start and the PV (process variable) will be indicated on the PV display and SV1 or SV2 will be indicated on the SV display.

While control output OFF function is working, is indicated on the PV display. To release the function, press the OUT/OFF key for approx. 1 second.
