4. Setup and Installation
4.1 Mounting
The AX4-1A is designed for panel mounting. Ensure the panel cutout dimensions are appropriate for a 48x48mm device. Secure the controller using the provided mounting brackets.
4.2 Wiring
WARNING: Disconnect all power before performing any wiring to prevent electric shock or damage to the unit.
Refer to the wiring diagram provided with your unit for specific terminal connections. General wiring considerations include:
- Power Supply: Connect the 100-240 V a.c, 50/60 Hz power supply to the designated power terminals.
- Input Sensor: Connect your thermocouple (K, J, T) or RTD (Pt100 Ω) sensor to the input terminals. Ensure correct polarity for thermocouples.
- Control Output: Connect your load (e.g., heater, SSR) to the appropriate output terminals (Relay or Voltage Pulse). Observe the maximum current and voltage ratings for the output type.

5. Operating Instructions
5.1 Front Panel Overview
Image 5.1: Front view of the HANYOUNG AX4-1A Temperature Controller, displaying two 4-digit LED readouts (PV and SV), indicator lights (AL1, AL2, OUT, TUNE), and three control buttons: MODE, Up arrow, and Down arrow.
- PV Display (Red): Shows the current process value (measured temperature).
- SV Display (Green): Shows the set value (desired temperature).
- Indicators: AL1, AL2 (Alarm indicators), OUT (Output status), TUNE (Auto-tuning status).
- MODE Button: Used to cycle through parameters and confirm settings.
- Up/Down Buttons: Used to adjust set values and parameter settings.
5.2 Basic Operation
- Power On: After proper wiring, apply power to the unit. The PV and SV displays will illuminate.
- Setting the Set Value (SV): In normal operating mode, use the Up and Down arrow buttons to adjust the SV to your desired temperature. The SV display will flash during adjustment.
- Monitoring: The PV display will show the current temperature, and the OUT indicator will show when the control output is active.
5.3 Parameter Settings and Auto-Tuning
To access advanced settings such as input type, control method (PID/ON-OFF), alarm settings, and auto-tuning, press and hold the MODE button for a few seconds. Use the Up/Down buttons to change values and the MODE button to confirm and move to the next parameter. Refer to the detailed parameter list in the full manual for specific codes and ranges.
- Auto-Tuning: This function automatically calculates optimal PID parameters for your system. Activate auto-tuning from the parameter menu. The TUNE indicator will flash during the process.
- Control Output Operation: Select between Reverse operation (heating control) or Direct operation (cooling control) based on your application requirements.
6. Maintenance
The HANYOUNG AX4-1A Temperature Controller is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure longevity:
- Cleaning: Gently wipe the front panel with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Environmental Conditions: Ensure the operating environment remains within the specified temperature (-5 ~ 50°C) and humidity (35 ~ 85% RH, non-condensing) ranges.
- Connection Checks: Periodically inspect wiring connections for tightness and signs of corrosion.
7. Troubleshooting
If you encounter issues with your HANYOUNG AX4-1A, consider the following common troubleshooting steps:
- No Power/Display: Check the power supply connections and ensure the correct voltage is applied. Verify the power fuse if accessible.
- Incorrect Temperature Reading (PV): Verify the sensor wiring and ensure the correct input type is selected in the parameter settings. Check for sensor damage.
- No Output Control: Check the output wiring. Ensure the SV is set correctly and the control output operation (heating/cooling) matches your application. Verify that the OUT indicator illuminates when expected.
- Unstable Control: If temperature oscillates excessively, re-run the auto-tuning function or manually adjust PID parameters if you have expertise.
- Error Codes: If the display shows an error code, consult the full product manual for specific interpretations and solutions.
