6.1 Quick Hardware Tests
These basic checks help confirm that the SmartSampler hardware is operational before deeper troubleshooting.
- Power-on LED check
When powering up, the status LED should blink to indicate system initialization. A steady light indicates normal operation. No light means power is not reaching the controller. - Cleaning
Keep connectors, cable ends, and housing free from dust, salt, or debris. Clean gently with a soft cloth. For field units, rinse housing surfaces with fresh water after exposure to rain or splash water. Never use solvents.
6.2 Troubleshooting
Common issues and first-level solutions:
- Blown fuses & wiring faults
- Check inline fuses on power input if the unit does not start.
- Replace only with the correct rating.
- Inspect wiring for loose connections, corrosion, or frayed cables.
- Overcurrent trips & thermal issues
- If modules shut down unexpectedly, check for blocked pumps or valves drawing too much current.
- Allow the unit to cool and inspect for overheating near power regulators.
- Reset by cycling power after the cause is corrected.
- Water ingress detection
- Inspect sealing gaskets and cable glands regularly.
- If internal condensation or droplets are visible, disconnect immediately and dry thoroughly before reuse.
- Persistent ingress requires resealing or service.
Note:
Always document any repeated faults or irregular behavior. This information helps trace issues during support requests.
