5. Installation and Wiring

Before proceeding with installation, ensure the main power supply is completely disconnected to prevent electric shock.

Wiring Instructions:

Red Wire: Connect to the input 220V fire wire (Live).
Green Wire: Connect to the input 220V neutral line.
Yellow Wire: Connect to the output 220V fire wire (Live) of the appliance.
Important: The neutral wire cannot be reversed. Reversing it will result in no output from the yellow wire. Live wiring is strictly prohibited.

Common wiring diagram for double switch control with IO33H01 — Common wiring diagram for double switch control. The electrical appliance will be turned off after a delay following power failure. The zero line connects directly to the delayer and light fixture without going through any switch. For single open double control switches (e.g., 86 Switch/Rocker Switch), the live wire goes straight to the light wire for continuous operation when the mechanical switch is ON. When the mechanical switch is OFF, the live wire connects to the red wire, powering the delay device, which then disconnects the equipment after the delay.

6. Operating Instructions

The IO33H01 module functions as a delayed power-off device. Once the set delay time elapses, the power supply to the connected appliance is stopped.

Operating Steps:

Set Delay Time: Before powering on, set the desired delay time using the DIP switches (refer to Section 7). No live settings are allowed.
Power On: After verifying all wiring is correct and secure, apply power to the module. The LED indicator (PWR) will illuminate constantly, indicating the module has started its operation.
Delay Completion: Once the set delay time has elapsed, the module will stop providing power to the connected appliance. The LED indicator (PWR) will then begin to flash, signaling that the delay is over and the power is off.

Additional Notes:

Early Shutdown: If you need to turn off the appliance before the delay time expires, simply disconnect the main power supply to the module.
Restarting Delay: To initiate a new delay cycle, you must re-power the module after it has been turned off.

7. Delay Time Setting

The IO33H01 module offers 16 different delay modes, adjustable via a DIP switch. Always ensure the module is powered off before adjusting the DIP switches.

Setting Procedure:

Disconnect Power: Ensure the module's main power supply is completely disconnected.
Refer to Table: Consult the "Io33h01 Setting Delay Time 16 Modes Reference Table" below to identify the DIP switch configuration for your desired delay time.
Adjust DIP Switches: Toggle the red DIP switches (labeled 1, 2, 3, 4) on the module according to the pattern shown in the reference table for your chosen delay.
Verify and Power On: After setting, double-check your wiring and then re-apply power to the module.

8. Maintenance

The IO33H01 module is designed for reliable operation with minimal maintenance. To ensure its longevity and proper function:

Keep the module clean and free from dust and debris.
Avoid exposing the module to excessive moisture, direct sunlight, or extreme temperatures.
Periodically check wiring connections to ensure they remain secure.
Do not attempt to open or repair the module yourself, as this may void any potential warranty and poses a safety risk.

9. Troubleshooting

If you encounter issues with your IO33H01 module, consider the following common troubleshooting steps:

Module not powering on / LED not lighting up:
- Check the main power supply connection.
- Verify input voltage is within the AC 110-220V range.
- Ensure wiring is correct and secure.
Appliance not turning off after delay:
- Confirm the delay time is correctly set using the DIP switches (refer to Section 7).
- Check the output wiring to the appliance.
- Ensure the appliance's power consumption does not exceed the module's maximum control power.
Yellow output wire has no output:
- This often indicates the neutral wire has been reversed. Disconnect power immediately and re-check your wiring according to the diagrams in Section 5.
Module behaves erratically:
- Disconnect power, wait a few seconds, and then re-apply power to reset the module.
- Ensure the operating environment is within specified temperature and humidity ranges.

If problems persist after attempting these steps, please contact the seller or a qualified technician for assistance.

10. User Tips

Based on common usage scenarios, here are some tips for optimizing your experience with the IO33H01 module:

Pre-test Setup: Before final installation, it's advisable to temporarily wire the module with a low-power test load (e.g., a small lamp) to confirm the delay settings and basic functionality.
Labeling: For complex setups, consider labeling the wires and the module itself to easily identify connections and settings.
Ventilation: While the module has a protective feature, ensuring good ventilation around it can help dissipate heat, especially when controlling higher-wattage appliances.
Consider the "With Shell" Option: If the module is to be installed in an exposed area or where it might be subject to dust or accidental contact, the version with the protective shell offers enhanced durability and safety.
