4. Parentah Operasi
4.1 Pamilihan Fungsi
- GRT6-A (Delay ON): The output relay activates after a preset delay time once the supply voltage diterapkeun.
- GRT6-B (Delay OFF): The output relay deactivates after a preset delay time once the supply voltage dipiceun.
4.2 Setélan Waktu
The delay time is set using two potentiometers (knobs) on the front panel:
- Knob 1 (Delay Gear Setting): Selects the time range (e.g., seconds 's', minutes 'm', hours 'h', days 'd'). It also includes 'ON' for relay action (15-18/25-28 closed) and 'OFF' for relay open (15-18/25-28 open) for continuous operation modes.
- Knob 2 (Fine Adjustment): Provides a fine adjustment of the delay time from 10% to 100% within the selected range.
Itungan: Delay time = Knob 1 setting × Knob 2 percentage.
Examples:
- To set a 5-second delay: Set Knob 1 to '10s', and Knob 2 to '50%'. Delay time = 10s × 50% = 5s.
- To set an 8-minute delay: Set Knob 1 to '10m', and Knob 2 to '80%'. Delay time = 10m × 80% = 8m.

4.3 Indikator
- Green LED (Un): Indicates the presence of supply voltage.
- Red LED (R): Indicates the status of the output relay.
5. Pangropéa
The GEYA GRT6 series time relays are designed for reliable, long-term operation with minimal maintenance. To ensure optimal performance:
- Jaga alat tetep beresih sareng bebas tina lebu sareng lebu.
- Periodically check all electrical connections for tightness and ensure they are free from corrosion.
- Avoid exposing the device to extreme temperatures, humidity, or corrosive environments beyond its specified operating conditions.
- Do not attempt to open or repair the device yourself. Refer to qualified personnel for any servicing needs.
6. Cara ngungkulan
If the time relay is not functioning as expected, consider the following troubleshooting steps:
- No Power Indication (Green LED Off): Check the power supply connections (A1-A2) and ensure the correct voltage diterapkeun.
- Relay Not Activating/Deactivating:
- Verify the wiring connections to the load (terminals 15, 16, 18 or 25, 26, 28).
- Ensure the time setting is correctly configured for the desired delay.
- Check the output relay status using the Red LED indicator.
- Incorrect Timing:
- Re-check the settings on both potentiometers (Knob 1 for range, Knob 2 for fine adjustment).
- Ensure the ambient temperature is within the specified operating range, as extreme temperatures can affect timing accuracy.
- Overheating Alat: Ensure adequate ventilation around the device and that it is not overloaded beyond its rated current.
If problems persist after performing these checks, contact GEYA customer support.

8. Tips pamaké
- Understanding Delay Functions: The GRT6-A is a 'delay on connection' type relay, meaning the output activates after a set time once power is applied. The GRT6-B is a 'delay off' type, where the output deactivates after a set time once power is removed. Ensure you select the correct model for your application.
- Voltage Kasaluyuan: Always confirm the voltage of your power supply matches the relay's specified voltage (AC230V or AC/DC24-240V) to prevent damage.
- Aplikasi Versatility: These relays are widely applicable in industrial automation, power systems, household appliances, and automotive electronics. Consider their use for controlling motors, lighting, or other timed processes.
