AUTONICS TNS (01) PDF Document

The AUTONICS TNS provides several advanced features for precise temperature control:

2-DOF PID algorithm optimized for various control environments.

50 ms high-speed sampling and plus or minus 0.2% display accuracy.

Program control and fixed control models available. Program control allows up to 10 patterns by 20 steps program setting. Fixed control models include a timer function for preset operation.

Simultaneous heating/cooling and automatic/manual control functions.

Control functions including Group PID, Zone PID, and Anti Reset Windup (ARW).

Control status monitoring for up to 10 events.

RS485 communication output model available supporting Modbus RTU/ASCII, PLC ladderless, and Sync-Master protocols with speeds up to 115,200bps.

Heater burnout alarm function via CT input.

Parameter setting via PC using comprehensive device management software.

Shortcut key setting using the front user key button [U].

Easy maintenance with detachable terminal blocks.

Failure to follow these safety warnings may result in serious injury or death:

01. A fail-safe device must be installed when using the unit with machinery that may cause serious injury or substantial economic loss, such as nuclear power control, medical equipment, ships, vehicles, railways, aircraft, combustion apparatus, safety equipment, or crime/disaster prevention devices.

02. Do not use the unit in places where flammable, explosive, or corrosive gas, high humidity, direct sunlight, radiant heat, vibration, impact, or salinity may be present.

03. Install the unit on a device panel before use to prevent electric shock.

04. Do not connect, repair, or inspect the unit while it is connected to a power source.

05. Check ‘Connections’ before wiring to prevent fire.

06. Do not disassemble or modify the unit.

01. When connecting the power input and relay output, use AWG 20 (0.50 mm squared) cable or over, and tighten terminal screws to a torque of 0.74 to 0.90 N m. For sensor input and communication cables without dedicated cable, use AWG 28 to 16 cable and tighten to the same torque specifications.

02. Use the unit only within rated specifications to avoid fire or product damage.

03. Use a dry cloth to clean the unit; do not use water or organic solvents.

04. Keep the product away from metal chips, dust, and wire residue that could flow into the unit.

05. Check the polarity of terminals before wiring sensors. For RTD sensors, use a 3-wire type with cables of the same thickness and length. For thermocouple (TC) sensors, use the designated compensation wire.

06. Keep the unit away from high voltage lines or power lines to prevent inductive noise. Use line filters or varistors at power lines and shielded wire at input signal lines if necessary.

07. Warm up the unit for at least 20 minutes after turning on the power for accurate temperature measurement.

The following table lists common input types and their supported ranges for the AUTONICS TNS:

The terminal connections for the AUTONICS TNS model are as follows:

Terminals 1 and 2: Control Output 1 (Relay, SSR, or Current/SSR drive).

Terminals 3 and 4: Control Output 2 (Relay, SSR, or Current/SSR drive).

Terminals 5 and 6: Power Source (100 – 240 VAC).

Terminals 13 and 14: AL1 (Alarm Output 1).

Terminals 15 and 16: AL2 (Alarm Output 2).

Terminal 7: Communication Output RS485 (A+).

Terminal 8: Communication Output RS485 (B-).

Terminal 9: Transmission Output (mA) / Digital Input 1.

Terminal 10: Digital Input 2.

Terminals 11 and 12: Sensor Input (RTD, TC, or Analog voltage/current). Terminal 11 (A/plus), Terminal 12 (B/minus), Terminal 18 (B’ for RTD).

Terminal 17: Current Transformer (CT) input.

To reset all parameters to their default values on the AUTONICS TNS, follow these steps:

Step 01. Press the [Left Arrow], [Up Arrow], and [Down Arrow] keys simultaneously for over 5 seconds in run mode. The display will show INIT turned ON.

Step 02. Change the setting value to YES by pressing the [Up Arrow] or [Down Arrow] keys.

Step 03. Press the [M] key to reset all parameter values as default and return to run mode.

The AUTONICS TNS front panel consists of the following components:

1. PV display part (White): Displays the Present Value (PV) and unit in RUN mode; displays parameter names in setting mode.

2. SV display part (Green): Displays the Setting Value (SV) and unit in RUN mode; displays parameter setting values in setting mode.

3. Operating value display part (Yellow): Displays selected values such as Manipulated Value (MV), P/S, TM, or CT with unit.

4. Temperature control indicator: Shows relative PV status based on SV (Up, Hold, or Down arrows).

5. Operation status indicators: Includes LOCK (key lock), PROG (program control), WAIT (waiting status), and HBA1/2 (heater break alarm).

6. Output status indicators: Includes OUT1/2 (control output), AT (auto-tuning), MAN (manual control), STOP (control stop), HOLD (program hold), and AL1 to 6 (alarm output).

7. Input keys: [U] User key, [M] Mode key, and [Left], [Down], [Up] setting value control keys.

The AUTONICS TNS uses a password system for security and specific key combinations to enter different modes:

Password Input: If a password is set, you must enter it to access parameters. Use the [Left], [Up], and [Down] keys to enter the password and the [M] (MODE) key to confirm.

SV Setting: Use the [Left], [Up], and [Down] keys in auto control mode to move digits and change the setting value. Save and return by pressing [M] or waiting 3 seconds.

Control Output Run/Stop: Press the [Down] and [Up] keys together for 3 seconds.

Key Lock: Press the [Left] and [Down] keys together for 3 seconds to toggle the key lock ON/OFF.

Parameter Group Entry: Press the [M] key for 2 seconds to enter the parameter groups.

When wiring the AUTONICS TNS, use terminals with the following specifications:

Shape: Fork crimp terminal or Round crimp terminal.

Inner diameter: Greater than or equal to 3.0 mm.

Outer width: Less than or equal to 5.8 mm.
