4.設置と配線
4.1 取り付け
The GEYA GRT6-B1 is designed for standard 35mm DIN rail mounting. Ensure the rail is securely fastened and provides adequate space for ventilation and wiring.
4.2配線接続
Connect the power supply and load according to the wiring diagrams provided. The GRT6-B1 model features A1(+) and A2(-) for supply terminals, S for trigger terminal, and 15, 16, 18 for the 1SPDT output contacts (15-16 normally closed, 15-18 normally open).

5. 操作手順
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.

Figure 5: Timing diagrams for Delay ON (A) and Delay OFF (B) functions.
5.2 時間設定
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ノブ: Fine-tune the delay time within the selected range by setting a percentage (e.g., 50% of 10s = 5 seconds).
例えばample, 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。 トラブルシューティング
If the relay does not function as expected, consider the following common issues:
- No Power Indication (Green LED off): 電源の接続を確認し、電圧を確認してくださいtage is within the specified range (AC/DC 24V-240V).
- 負荷が切り替わらない: 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.
- 遅延時間が正しくありません: Re-check the settings on both the time range and percentage knobs. Ensure they are set according to your desired delay.
- 断続動作: 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.
