1. Introduction
The Hanyoung Nux MA4N-C is an analog multi-timer designed for various industrial and commercial applications requiring precise time control. This device features multiple time unit and range settings, along with reset, start, and prohibited input capabilities, and six distinct output operation modes. It operates on a wide voltage range of 24-240V AC/DC and utilizes an 8-pin socket type for installation.

This image displays the timer's front panel, including the analog dial for time setting, output (OUT) and power (PW) indicators, and mode selection switch. The dial shows markings from 0 to 30 seconds, indicating its timing capability.
2. Setup and Installation
2.1 Mounting
The MA4N-C timer is designed for panel mounting or socket mounting using an 8-pin socket. Ensure the mounting location is stable, free from excessive vibration, and within the specified ambient temperature and humidity ranges.
2.2 Wiring
Connect the timer to its designated 8-pin socket. Refer to the wiring diagram provided with your specific socket for correct terminal connections. Ensure all power connections adhere to local electrical codes and safety standards.
- Power Supply: Connect the power supply to the appropriate terminals. The timer accepts 24-240V AC/DC.
- Input Signals: Connect START, INHIBIT, and RESET input signals as required by your application. These inputs are non-voltage type.
- Output Connections: Connect the load to the output terminals. The MA4N-C provides Time Limit 2c, Time Limit 1c, and Instantaneous 1c output types. Refer to the specifications for output ratings.
3. Operating Instructions
3.1 Power On
Once correctly wired and mounted, apply power within the 24-240V AC/DC range. The 'PW' indicator on the front panel will illuminate, indicating that the timer is receiving power.
3.2 Setting Time
Rotate the analog dial on the front panel to set the desired time delay. The timer supports multiple time units and ranges. Ensure the selected range corresponds to your application's requirements. The dial typically shows markings in seconds or minutes, depending on the model's configuration.
3.3 Mode Selection
The MA4N-C features six output operation modes. Use the 'MODE' switch or selector on the front panel to choose the desired operation mode. Refer to the product's detailed mode selection guide (if available separately) for specific functions of each mode.
3.4 Input Functions
- START Input: Initiates the timing sequence.
- INHIBIT Input: Pauses or prevents the timing sequence.
- RESET Input: Resets the timer to its initial state.
Ensure input signals meet the minimum signal length requirements (e.g., Min. 20 ms for START and INHIBIT inputs).
3.5 Output Operation
When the set time elapses and the conditions for the selected operation mode are met, the timer's output contacts will switch. The 'OUT' indicator on the front panel will illuminate, signifying an active output. The MA4N-C provides both Normally Open (N.O) and Normally Closed (N.C) contacts with specified current and voltage ratings.
4. Maintenance
The Hanyoung Nux MA4N-C Analog Multi Timer is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure optimal performance:
- Cleaning: Keep the timer's exterior clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using abrasive cleaners or solvents.
- Environmental Conditions: Ensure the operating environment adheres to the specified ambient temperature (-10 to 55 °C) and humidity (35 to 85 %R.H., non-condensing) ranges.
- Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion.
- Inspection: Visually inspect the timer for any signs of damage or wear.
5. Troubleshooting
If the timer is not functioning as expected, consider the following common issues:
- No Power Indicator (PW LED off):
- Check the power supply voltage and ensure it is within the 24-240V AC/DC range.
- Verify all power connections are secure.
- Check for blown fuses in the power circuit.
- Timer Not Starting/Resetting:
- Ensure the START/RESET input signals are correctly wired and meet the minimum signal length requirements.
- Verify the input signal type (non-voltage input).
- Check the selected operation mode; some modes may require specific conditions to start.
- Output Not Activating:
- Confirm the set time has elapsed.
- Check the selected output operation mode and its conditions.
- Verify the load connected to the output is within the specified current and voltage ratings.
- Inspect output wiring for continuity and secure connections.
- Inaccurate Timing:
- Ensure the time setting dial is correctly positioned.
- Check for stable power supply; voltage fluctuations can affect timing accuracy.
- Verify the ambient temperature is within the specified range, as extreme temperatures can affect performance.
If problems persist after performing these checks, contact technical support.
