The HLS PS Series provides a backup power supply for fire control systems, operating at 115/230 Vac and 50/60 Hz. It features two models, HLS PS25 and HLS PS50, with different output current capabilities. The unit includes various indicators for status monitoring, such as power, fault, battery status, and output status. It is designed to comply with EN54-4 requirements and offers features like transient protection, fault relay for remote reporting, and a test button for battery checks. Installation involves mounting a back box, connecting cables, and configuring DIP switches for specific functions.
Troubleshooting and error codes
| Indicator/Fault | Possible Cause | Solution |
|---|---|---|
| FUS BAT FAULT | Battery fuse is open | Check and replace battery fuse if necessary. |
| LOW BAT | Battery below 25% capacity or voltage close to 22.4 Vdc | Check battery condition and charging. If voltage is below 20.4 Vdc, outputs may fail. |
| NO BAT | Battery is not detected | Ensure battery is properly connected. |
| BAT TEST | Dynamic test running | Wait for the test to complete. Battery is supervised every 3 hours. |
| BAT CH | Charging battery | Normal operation. |
| BAT DIS | Discharging battery | Normal operation. |
| IN ALARM | Alarm input activated | Battery charger disabled. Alarm input has been triggered. |
| FAULT LED | General Power Supply Fault | Refer to specific fault indicators (e.g., MAINS SUPPLY FAULT, BATTERY FAULT). |
| MAINS SUPPLY FAULT Led | Power supply not detected (after 8 minutes delay) | Check main power connection. Unit is running on batteries. |
| BATTERY FAULT Led | Battery not detected or voltage below 22.4 Vdc | Check battery connection and health. |
| OUTPUT 1/2 FAULT Led | Output not powered | Check output connections and load. |
| EARTH FAULT Led | Earth fault detected | Ensure no links between Earth and output terminals. Check J3 connection. |
| OVERLOAD Led | Equipment exceeds maximum current | Reduce load on the outputs. |
| SYSTEM FAULT Led | Power Supply microprocessor not operating correctly | Contact manufacturer for support. |
