Industry Applications
1. Lamp problems
The lamp reaches the end of service life or the filament is burnt out.
Air leakage or lamp aging fails gas ionization.
Mismatch between lamp model/power and ballast.
2. Ballast internal faults
Damaged starting capacitor or resonant capacitor.
Burned inverter tubes and rectifier components.
Circuit board dampness, corrosion or open circuit.
Ballast failure with no high-voltage output.
3. Power supply and wiring faults
Too low input voltage, phase loss or unstable power supply.
Loose wiring, poor contact or broken cable.
Short circuit or electric leakage triggers ballast protection.
4. Working environment factors
Ambient temperature is too low to ignite the UV lamp.
Excessive humidity reduces insulation and triggers protection.
Frequent start-stop causes overheat protection lockout.
5. Matching and setting errors
Wrong dimming signal setting makes the ballast stay in sleep mode.
Incorrect wiring configuration for multi-lamp driving.
