Communication Installation Instructions KT4H/B Temperature Controller

No. KT4HCE4 2009.11

These instructions are for communication functions. For detailed operating instructions, please refer to User’s Manual for the KT4H/B.

Serial communication and Tool port communication cannot be used together. When performing Serial communication, remove the tool cable (AKT4H820) from the USB port of the PC and tool connector of the KT4H/B.

When performing Tool port communication, it is not required to remove the Serial communication cables. However, do not send a command from the master side.

(Fig. 2-3)

Shielded wire

Connect only one side of the shielded wire to the FG terminal so that current cannot flow to the shielded wire. If both sides of the shielded wire are connected to the FG terminal, the circuit will be closed between the shielded wire and the ground. As a result, current will run through the shielded wire and this may cause noise. Be sure to ground the FG terminal.

Terminator (Terminal resistor)

Do not connect terminator with the communication line because each KT4H/B has built-in pull-up and pull-down resistors instead of a terminator.

If there is a large distance between the PLC and the KT4H/B, connect the terminator on the PLC side. (Connect a terminator of 120 or more resistance.)

The slave will not respond to the master in the following cases.

 

No response

 

• Global address “FF” (MEWTOCOL) is set.

 

 

• Broadcast address (Modbus protocol) is set.

 

 

 

 

(Fig.4-1)

 

• Communication error (framing error, parity error)

 

 

 

 

• LRC discrepancy (Modbus ASCII mode)

 

 

 

• CRC-16 discrepancy (Modbus RTU mode)

RS-485 communication timing

Master side (Notice on programming)

Set the program so that the master can disconnect the transmitter from the communication line within a 1 character transmission period after sending the command in preparation for reception of the response from the slave.

To avoid the collision of transmissions between the master and the slave, send the next command after carefully checking that the master received the response.

Slave side

When the slave starts transmission through the communication line, the slave is arranged so as to provide an idle status (mark status) transmission period of 5ms or more (communication response time from 5 to 99ms settable) before sending the response to ensure the synchronization on the receiving side.

The slave is arranged so as to disconnect the transmitter from the communication

line within a 1 character transmission period after sending the response.

2.4 Mounting and removal to/from the control panel How to mount the KT4H/B (Fig.2.4-1, Fig.2.4-2)

Mount the controller vertically to ensure it adheres to the Dust-proof/Drip-proof specification (IP66). Mountable panel thickness: Within 1 to 5mm

(1)Insert the controller from the front side of the panel.

(2)Insert the mounting frame until the frame tips come into contact with the panel, and fasten with screws. Tighten screws with one rotation upon the screw tips touching the panel. Torque: 0.05 to 0.06N•m.

How to remove the mounting frame (Fig.2.4-3)

(1) Turn the power to the unit OFF, and disconnect all wires before removing the mounting frame.

(2) Insert a flat blade screwdriver between the screw frame and unit 1 .

(3) Slowly push the frame upward using the screwdriver 2 while pushing the unit toward the panel 3 .

(4) Repeat step (2) and slowly push the frame downward using the screwdriver for the other side. The frame can be removed little by little by repeating these steps.

3. Wiring

Warning

Turn the power supply to the instrument off before wiring or checking it. Working or touching the terminal with the power switched on may result in severe injury or death due to Electric Shock.

Caution

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 by the terminal screw. The torque is approximately 0.63N•m.

When using a terminal cover (AKT4H801), pass terminal wires numbered 7 to 12 into the holes of the terminal cover. See (Fig. 3-2).

To extend a thermocouple’s lead wire, be sure to use a compensating lead wire in accordance with the sensor input specification. (If any other compensating lead wire is used, a temperature indication error may be caused.)

Use the 3-wire RTD which corresponds to the input specification of this controller.

This controller does not have a built-in power switch, circuit breaker or fuse. Therefore, 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, externally 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.

If Alarm 2 and Heater burnout alarm are added together, they (EVT2) utilize

common output terminals.

Lead wire solderless terminal

 

 

When using a Terminal cover

Use a solderless terminal with an insulation sleeve in which an M3 screw

fits as shown below. The torque is approximately 0.63N•m.

Power

 

 

 

 

 

 

 

 

 

 

Use the current transformer (CT) provided, and pass one lead wire of the

CT

supply

heater circuit into the hole of the CT. (Fig.3-4) When wiring, keep the CT

 

 

 

 

 

 

 

wire away fromAC 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 (14, 15) terminals.

4. Operation

Heater

(Fig. 3-4)

 

 

After the unit is mounted to the control panel and wiring is completed, operate the unit following the procedures below.

(1)Turn the power supply to the KT4H/B ON.

(2)Initial settings

Refer to “5. Operation flowchart”, “6. Basic operation” and “7. AT Perform/Cancel”. Select an input type, alarm type, Direct/Reverse action, etc. during Setup mode. If initial settings are not required, skip this step, and proceed to step (3).

(All set values are locked)

 

: Lock 2

(All set values except SV are locked)

: Lock 3

(Set values can be changed temporarily, however, after the power is

turned off and on, they return to their previous values.)

(4) Turn the load circuit power ON.

Control action starts so as to keep the control target at the SV (desired value).

6. Basic operation (Main setting mode, When setting SV to 100)

(1)

Proceed to the Main setting mode.

 

Press

key in the PV/SV display mode.

 

The unit proceeds to the Main setting mode.

(2)

Set SV.

 

Set SV with or key.

 

or

 

(3)

Register the SV.

 

 

Register the SV by pressing

key.

 

The unit reverts to the PV/SV display mode.

(4)

Control starts.

 

 

Control starts so as to keep the measuring temperature

 

at 100 .

 

7. AT Perform/Cancel (PID action)

In order to set each value of P, I, D and ARW automatically, the auto-tuning process should be made to fluctuate to obtain an optimal value. Sometimes the auto-tuning process will not fluctuate if auto-tuning is performed at or near room temperature. Therefore auto-tuning might not finish normally.

(1)

Proceed to the Sub setting mode.

 

 

Press

key while pressing

key in the PV/SV display

mode. The unit proceeds to the Sub setting mode.

and

(2)

Select AT Perform/Cancel.

Select AT Perform with key, or select AT Cancel with key.

or

(3)

Confirm AT Perform/Cancel.

Press key.

The unit reverts to the PV/SV display mode.

(4)

AT Perform/Cancel

While AT is performing, the AT indicator flashes, and it goes off when AT is cancelled.

Auto-reset can be performed during P or PD action. Auto-reset is cancelled in approximately 4 minutes. It cannot be released while performing this function.
