2. Configuració i instal·lació
Proper installation is crucial for the safe and effective operation of the device. This device is designed for DIN rail mounting. Ensure all power is disconnected before proceeding with installation.
Diagrama de cablejat:

This diagram illustrates the difference between upper wiring and down wiring configurations. For the GPS8-01 (Down Wiring) model, the incoming line connects to the bottom terminals (N and 1), and the outgoing load connects to the top terminals (N and 2).
Passos d'instal·lació:
- Mount the device securely onto a standard DIN rail.
- Connect the neutral (N) and live (L) wires from the power supply to the designated input terminals (N and IN) on the device. For the GPS8-01 (Down Wiring) model, these are the bottom terminals.
- Connect the load wires (neutral and live) from your household equipment to the output terminals on the device. For the GPS8-01 (Down Wiring) model, these are the top terminals.
- Assegureu-vos que totes les connexions estiguin ben ajustades i segures per evitar contactes solts i possibles perills.
- Once wiring is complete, restore power to the circuit. The device will power on and display the current voltage.

3. Instruccions de funcionament
Tauler acabatview:

The GPS8-01 panel features a digital display for operating voltage, an under-voltage indicator, an over-voltage indicator, and a power open/close indicator. It includes 'M' (Menu/Mode), 'Up', and 'Power' buttons for control.
Configuració de paràmetres:

To enter the parameter setting interface, press the 'M' button for 3 seconds. Use the 'Up' and 'Down' (implied by context, though only 'Up' is shown as a button) buttons to adjust values. Short press 'M' to cycle through settings: Overvoltage setting (230V-300V, factory default 275V), Undervoltage setting (145V-210V, factory default 175V), and Reset time setting (2s-900s, factory default 30s). Long press 'M' for 3 seconds to exit the setup mode and return to running mode. If no key is operated for 60 seconds, the device will automatically exit the setting interface.
4. Manteniment
The GEYA Overvoltagi Undervoltage Protective Device is designed for minimal maintenance. However, regular checks can ensure its continued optimal performance.
- Neteja: Periodically wipe the device with a dry, soft cloth to remove dust and debris. Do not use abrasive cleaners or solvents.
- Comprovació de la connexió: Annually, or if you suspect an issue, verify that all wiring connections are secure and free from corrosion. Ensure power is off before checking connections.
- Condicions ambientals: Assegureu-vos que el dispositiu funcioni dins dels rangs de temperatura i humitat especificats per evitar danys.
- Firmware: This device does not typically require user-updatable firmware.
5. Solució De Problemes
If you encounter issues with your GEYA Overvoltagi Undervoltage Protective Device, refer to the following common troubleshooting steps:
| Problema | Causa possible | Solució |
|---|---|---|
| Device not powering on/display is blank. | No power supply; loose wiring; internal fault. | Check power source. Ensure wiring is correct and secure. If problem persists, contact support. |
| El dispositiu s'encén amb freqüència. | Voltage outside set parameters; faulty appliance; incorrect settings. | Verify actual voltage with a multimeter. Check connected appliances for faults. Review and adjust over/under voltage configuració. |
| Display shows error code or abnormal reading. | Internal malfunction; extreme voltage condició. | Note the error code. Disconnect and reconnect power. If error persists, contact support. |
| Device does not self-reset. | Fault condition still present; reset time setting too long; internal fault. | Assegureu-vos que el voltage has returned to normal range. Check the reset time setting. If necessary, manually reset by cycling power. |
For issues not covered here, or if troubleshooting steps do not resolve the problem, please contact GEYA customer support.
