5. Funtzionamendu-argibideak
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 Ordua ezartzea
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 Eskutokia: Fine-tune the delay time within the selected range by setting a percentage (e.g., 50% of 10s = 5 seconds).
Adibidezample, 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. Arazoak
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).
- Load Not Switching: 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.
- Etengabeko funtzionamendua: 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.
8. Mantentzea
The GEYA GRT6-B1 relay is designed for reliable, long-term operation with minimal maintenance. Follow these guidelines:
- Garbiketa: Mantendu gailua garbi eta hautsik eta hondakinik gabe. Erabili zapi lehor eta leun bat garbitzeko. Ez erabili garbitzaile likidorik.
- Ikuskapena: Aldian-aldian egiaztatu kableatu-konexioak estutasuna eta higadura edo kalteen zantzurik dagoen egiaztatzeko.
- Ingurumena: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent premature aging or malfunction.
