5.1 Function Mode (Delay OFF)
The GRT6-B1 operates in Delay OFF mode (Function B). In this mode, when input voltage U is applied, the relay contacts change state immediately and timing begins. When the delay time is complete, the contacts return to their shelf state. If input voltage U is removed before the delay is complete, the contacts return to their shelf state immediately. The trigger switch is not used in this function.

5.2 ການຕັ້ງຄ່າເວລາ
The delay time is set using two rotary knobs on the front panel: one for the time range and one for the percentage of that range.
- Adjust Time Range Knob: Select the desired time range (e.g., 10s, 1m, 1h, 1d, 10d).
- Adjust Percentage Knob: Fine-tune the delay time within the selected range by setting a percentage (e.g., 50% of 10s = 5 seconds).
ຕົວຢ່າງample, to set a delay of 5 minutes:
- Adjust the time range knob to '10m' (10 minutes).
- Turn the percentage knob to '50%' (50% of 10 minutes = 5 minutes).

7. ການແກ້ໄຂບັນຫາ
If the relay does not function as expected, consider the following common issues:
- No Power Indication (Green LED off): Check the power supply connections and ensure the voltage is within the specified range (AC/DC 24V-240V).
- ການໂຫຼດບໍ່ສະຫຼັບ: Verify the load wiring. Ensure the load's voltage and current requirements do not exceed the relay's contact ratings (10A/AC1, 250VAC/24VDC). Check if the red LED indicates working status.
- Incorrect Delay Time: Re-check the settings on both the time range and percentage knobs. Ensure they are set according to your desired delay.
- ການດໍາເນີນງານແບບບໍ່ຢຸດຢັ້ງ: Inspect all wiring for loose connections. Ensure the operating environment is within the specified temperature and humidity limits.
If issues persist, consult a qualified electrician or contact GEYA customer support.
