5. Instruccions de funcionament
The GRT8-B1 operates as a Delay OFF relay. The load turns on immediately with power application and turns off after the set delay time. The delay can be reset using an external button.
5.1 Setting the Time Delay
The delay time is set using two knobs on the front panel:
- Knob 1 (Time Range Selection): Selects the desired time range (e.g., 0.1-1s, 1-10s, 6-60s, 1-10min, 6-60min, 1-10hr, 0.1-1day, 1-10day, only ON, only OFF).
- Knob 2 (Time Percentage Setting %): Fine-tunes the delay within the selected range from 10% to 100%.
Figure 5.1: Illustration of the two adjustment knobs for setting the time delay: one for time range (e.g., 1s, 10s, 1m, 1h, 1d) and another for percentage (10%-100%).
ExampLI: To set a 5-minute delay, select the '10m' range with Knob 1 and set Knob 2 to 50%.
5.2 Delay OFF Function (GRT8-B1)
When power is applied, the output contact immediately closes (load turns ON). The relay then begins its timing cycle. After the set delay time expires, the output contact opens (load turns OFF).
Figure 5.2: Visual representation of the 'Delay OFF' function (Type B) where the load turns on with power and turns off after a set delay.
5.3 Resetting the Delay
An external button connected between terminals A1 and S can be used to reset the timing cycle. If the button is pressed during the timing delay, the load remains on, and the delay timer will not start until the button is released.

7. Manteniment
The GEYA GRT8-B1 time relay is designed for reliable operation with minimal maintenance. Regular checks should include:
- Periodically inspect terminal connections to ensure they are secure.
- Mantingueu el dispositiu net i lliure de pols i residus.
- Assegureu-vos una ventilació adequada al voltant del dispositiu per evitar el sobreescalfament.
- No utilitzeu netejadors abrasius ni dissolvents al dispositiu.
8. Solució De Problemes
If you encounter issues with your GRT8-B1 time relay, consider the following common problems and solutions:
- El dispositiu no s'encén: Comproveu la font d'alimentació voltage and ensure all connections are correct and secure. Verify the circuit breaker is not tripped.
- Load not switching: Confirm the output wiring is correct. Check the LED indicators for supply (green) and output (red) status. Ensure the time delay is set appropriately and has elapsed.
- Incorrect timing: Re-check the settings on both time range and percentage knobs. Ensure the knobs are firmly set to the desired values.
- High-pitched tone: Some users have reported a high-pitched tone when operating at lower voltages (e.g., 12V). This may be related to the internal switching power supply and is generally not indicative of a fault, but if excessive, contact support.
- Load remains on indefinitely: If using a reset button, ensure it is not stuck in the pressed position. The delay will not start until the button is released.
If problems persist after checking these points, please contact GEYA customer support.
