Figure 1: Front view of the AUTONICS TC4Y-14R PID Temperature Controller. The display shows four red digits for the process value and smaller indicators for SV (Set Value), AL1 (Alarm 1), OUT (Output), °F, and °C. Control buttons include an up arrow, MD (Mode), and a down arrow.

3.1. Front Panel Components

PV Display: Shows the current process value (e.g., temperature).
SV Indicator: Illuminates when the set value is displayed or being adjusted.
AL1 Indicator: Illuminates when Alarm 1 is active.
OUT Indicator: Illuminates when the control output is active.
°F/°C Indicators: Show the selected temperature unit.
Up/Down Buttons: Used to adjust parameter values.
MD (Mode) Button: Used to navigate through parameter groups and confirm settings.

4. Setup and Installation

4.1. Mounting

The TC4Y-14R is designed for panel mounting. Ensure adequate space for ventilation and wiring connections. Avoid mounting near heat sources or areas with excessive dust or moisture.

4.2. Wiring

Refer to the wiring diagram on the side of the unit or in the full technical specifications for precise connections. Ensure all power is off before wiring.

Power Supply: Connect 100-240VAC to the designated power terminals.
Sensor Input: Connect your temperature sensor (e.g., thermocouple, RTD) to the input terminals. Ensure correct polarity for thermocouples.
Control Output (Relay): Connect the load to the relay output terminals.
Control Output (SSR): Connect the Solid State Relay (SSR) input to the SSR output terminals.
Alarm Output (Optional): If using, connect alarm devices to the alarm output terminals.

Note: Incorrect wiring can cause damage to the unit or connected equipment. Always double-check connections.

5. Operating Instructions

5.1. Initial Power-Up

After completing all wiring, apply power to the unit. The display will show the current process value (PV).

5.2. Setting the Set Value (SV)

Press the MD button briefly. The SV indicator will illuminate, and the display will show the current set value.
Use the Up or Down buttons to adjust the set value to your desired temperature.
Press the MD button again to confirm the setting and return to PV display.

5.3. Parameter Settings

To access advanced parameters (e.g., PID constants, alarm settings, input type), press and hold the MD button for several seconds until the parameter group changes. Navigate through parameters using the MD button and adjust values with the Up/Down buttons. Refer to the full technical manual for a complete list of parameters and their functions.

6. Maintenance

The AUTONICS TC4Y-14R is designed for reliable operation with minimal maintenance.

Cleaning: Gently wipe the front panel with a soft, dry cloth. Do not use abrasive cleaners or solvents.
Inspection: Periodically check wiring connections for looseness or signs of damage.
Calibration: If precise accuracy is critical, periodic calibration of the temperature sensor and controller may be required by a qualified technician.

7. Troubleshooting

Problem	Possible Cause	Solution
No display/Power off	No power supply; Incorrect wiring	Check power connections and voltage; Verify wiring diagram.
Temperature reading inaccurate	Sensor faulty; Incorrect sensor type setting; Sensor not properly installed	Check sensor for damage; Verify input type parameter; Ensure sensor is correctly placed.
Output not activating	Wiring error; Set value too high/low; PID parameters incorrect	Check output wiring; Adjust SV; Review PID settings (P, I, D).
"HHHH" or "LLLL" on display	Sensor open circuit (HHHH) or short circuit (LLLL); Temperature out of range	Check sensor and wiring; Ensure operating temperature is within sensor's range.
