4. ການຕິດຕັ້ງແລະການຕິດຕັ້ງ
Proper installation is crucial for the reliable operation of the timer relay.
4.1 ການຕິດຕັ້ງ
The relay is designed for screw mounting. Ensure a stable surface for installation. Screws are not included with the product and must be sourced separately. The terminal block mount diameter is 6 x 5mm (L*W).
4.2 ສາຍໄຟ
Connect the relay to the appropriate DC24V power supply and control circuit using the 8-pin terminal block. Refer to standard DPDT relay wiring diagrams for your specific application. Ensure all connections are secure and insulated.
- ການປ້ອນຂໍ້ມູນພະລັງງານ: Connect DC24V to the designated power pins.
- DPDT Contacts: The relay provides two sets of changeover contacts (Double Pole Double Throw) rated for AC 250V 5A Resistive Load. Connect your load circuits to these contacts as required.
ສຳຄັນ: US buyers must verify that their power supply is DC24V to ensure compatibility and proper function of this item.
5. ຄໍາແນະນໍາການດໍາເນີນງານ
The Aexit AH3-3 timer relay operates as an off-delay device, meaning the timing sequence begins when power is removed from the control input.
5.1 ການກໍານົດເວລາຊັກຊ້າ
To adjust the off-delay time, gently rotate the front knob to the desired setting within the 0-10 second range. Do not attempt to remove the front knob, as this may damage the internal mechanism.
5.2 Off-Delay Operation
- When power is applied to the relay, the power indicator lamp will illuminate, and the DPDT contacts will immediately switch to their energized state.
- When power is removed from the relay, the internal timer begins counting down the set delay time.
- During the delay period, the DPDT contacts remain in their energized state.
- Once the set delay time has elapsed, the DPDT contacts will revert to their de-energized (normal) state.
6. ບໍາລຸງຮັກສາ
The Aexit AH3-3 timer relay is designed for long-term, reliable operation with minimal maintenance.
- ທໍາຄວາມສະອາດ: Periodically clean the exterior of the relay with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- ການກວດກາ: Regularly inspect wiring connections for tightness and signs of wear or corrosion.
- ສະພາບແວດລ້ອມ: ໃຫ້ແນ່ໃຈວ່າສະພາບແວດລ້ອມການເຮັດວຽກຍັງຄົງຢູ່ໃນຂອບເຂດອຸນຫະພູມແລະຄວາມຊຸ່ມຊື່ນທີ່ກໍານົດ.
7. ການແກ້ໄຂບັນຫາ
If you encounter issues with your Aexit AH3-3 timer relay, consider the following troubleshooting steps:
- Relay not powering on: Check the DC24V power supply connections and ensure power is present. Verify the power indicator lamp.
- Incorrect delay time: Ensure the front knob is set correctly. The time range is 0-10 seconds.
- Contacts not switching: Verify the load circuit connections. Check if the relay is receiving power and if the delay time is set. Ensure the load current does not exceed the AC 250V 5A resistive rating.
- ການດໍາເນີນງານເປັນລະຫວ່າງ: Inspect all wiring for loose connections or damage. Check for environmental factors like excessive vibration or temperature fluctuations.
