3. Setup and Installation
WARNING: Ensure all power is disconnected before attempting any installation or wiring to prevent electric shock or damage to the device.
3.1 Mounting
- Identify a suitable 35mm DIN Rail in your control panel or enclosure.
- Attach the provided 8-pin DIN Rail socket to the DIN Rail. Ensure it is securely fastened.
- Insert the H3Y-2 time relay into the 8-pin socket. It should click into place.
3.2 Wiring
The relay uses an 8-pin solder terminal for electrical connections. Refer to the wiring diagram (Figure 2) for specific pin assignments. Ensure all connections are tight and correct for AC 220V operation.
- Connect the AC 220V power supply to the designated input terminals on the 8-pin socket.
- Connect the load (device to be controlled) to the DPDT output contacts.
- Verify all wiring against the schematic to prevent misconnections.
4. Operation
4.1 Setting the Time Delay
- Locate the transparent time setting knob on the front of the H3Y-2 relay.
- Rotate the knob to align the red indicator with the desired time value between 0 and 10 minutes.
4.2 Powering On and Function
- Once installation and wiring are complete and verified, restore power to the circuit.
- The Power (PW) LED indicator on the relay will illuminate, indicating that the device is receiving power.
- The relay will begin its timed delay countdown.
- Upon completion of the set delay time, the Output Status (UP) LED will illuminate, and the relay contacts will switch, activating the connected load.
- The relay maintains this state until power is removed and reapplied, initiating a new delay cycle.

6. Maintenance
The uxcell H3Y-2 Delay Timer Time Relay is designed for reliable, long-term operation with minimal maintenance. However, periodic checks can help ensure optimal performance:
- Cleaning: Keep the relay and its socket free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
- Connections: Periodically inspect all wiring connections to ensure they remain secure and free from corrosion.
- Environmental Conditions: Ensure the operating environment remains within specified temperature and humidity ranges to prevent premature wear.
7. Troubleshooting
If the uxcell H3Y-2 Delay Timer Time Relay does not function as expected, consider the following common issues and solutions:
- No Power (PW LED Off):
- Check the AC 220V power supply to the relay socket.
- Verify all power connections are secure and correctly wired.
- Ensure the relay is fully seated in its 8-pin socket.
- Relay Does Not Switch After Delay (UP LED Off):
- Confirm the time setting knob is correctly set to a non-zero delay time.
- Check the load connections and ensure the load itself is functional.
- Verify the contact rating (5A 250VAC) is not exceeded by the connected load.
- Incorrect Delay Time:
- Re-adjust the time setting knob to the desired value.
- Ensure the knob is not obstructed and rotates freely.
If issues persist after performing these checks, contact uxcell customer support or a qualified electrician.
