Simultaneous heating/cooling and automatic/manual control functions.

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

Control status monitoring of 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 DAQMaster software and front loader port connectivity.

Easy maintenance with detachable terminal blocks and shortcut key setting with a front user key button.

The following warnings must be followed to avoid serious injury or death when using the AUTONICS TNH:

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

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 to use. Failure to do so may result in 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.

When wiring the AUTONICS TNH, follow these specifications to prevent fire or malfunction due to contact failure:

For power input and relay output: Use AWG 20 (0.50 mm2) cable or larger, and tighten the terminal screw with 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 the terminal screw with a torque of 0.74 to 0.90 N m.

Crimp Terminal Specifications: Use fork or round crimp terminals with an inner diameter of 3.0 mm or more and an outer width of 5.8 mm or less.

The AUTONICS TNH is designed to be used in the following environments:

Indoors (in the environment conditions rated in the specifications).

Altitude: Maximum 2,000 m.

Pollution degree: 2.

Installation category: II.

Ambient temperature: -10 to 50 degrees Celsius (Storage: -20 to 60 degrees Celsius).

Ambient humidity: 35 to 85% RH.

To perform a parameter reset on the AUTONICS TNH, follow these steps:

Step 01. Press the [◀], [▲], and [▼] keys simultaneously for over 5 seconds while in run mode until ‘INIT’ turns ON.

Step 02. Change the setting value to ‘YES’ by pressing the [▲] or [▼] keys.

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

The AUTONICS TNH features three main display parts and several status indicators:

1. PV Display Part (White): Displays the Present Value and unit in RUN mode, or the parameter name in setting mode.

2. SV Display Part (Green): Displays the Setting Value and unit in RUN mode, or the parameter setting value in setting mode.

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

Temperature Control Indicators:

Fixed Control: Shows relative PV status based on SV (High, Equal, or Low).

Program Control: Displays temperature control status as up, hold, or down.

Operation Status Indicators:

LOCK: Turns ON during key lock status.

PROG: Turns ON during program control.

WAIT: Turns ON during waiting status.

HBA1/2: Turns ON when the heater break alarm output is active.

The following table lists common error displays for the AUTONICS TNH:

The AUTONICS TNH supports various thermocouple and RTD inputs. Some examples include:

The RS485 communication interface for the AUTONICS TNH follows these standards:

Protocols: Modbus RTU/ASCII, Sync-Master, PLC ladderless.

Connection type: RS-485, RS-422A.

Maximum connection: 32 units (addresses 01 to 99).

Communication speed: Up to 115,200 bps.

Communication effective range: Maximum 800 m.

Data bit: 8 bit (fixed); Stop bit: 1 bit or 2 bit; Parity bit: None, Odd, or Even.

EEPROM life cycle: Approximately 1,000,000 operations.

According to the PDF, the AUTONICS TNH (H size) has the following dimensions:

Unit Body Size: Width 49 mm x Height 97 mm x Depth 69 mm.

Panel Cut-out: Width 45 mm (+0.6/-0) x Height 92 mm (+0.8/-0).

The unit should be inserted into the panel and fastened by pushing the bracket with tools like a flathead screwdriver.

When power is first supplied to the AUTONICS TNH, the following sequence occurs:

1. All display segments will flash for 1 second.

2. The model name is displayed sequentially (e.g., TNSP for model type and 42RR for power/output options).

3. The input specification (e.g., sensor type KCaH) will flash twice.

4. The unit enters RUN mode and displays the PV and SV.

Note: For accurate measurement, allow the unit to warm up for at least 20 minutes after turning it on.

Accessing settings on the AUTONICS TNH depends on the desired function:

SV Setting: Use the [◀], [▲], and [▼] keys in auto control mode to move digits and change values. Save by pressing [M] or waiting 3 seconds.

MV Setting (Manual Control): Use the [◀], [▲], and [▼] keys to adjust the manipulated value. Note that the TNS series does not support this mode.

Control Output Run/Stop: Press the [▼] and [▲] keys simultaneously for 3 seconds.

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

Key Lock: Press the [◀] and [▼] keys simultaneously for 3 seconds to toggle the key lock.
