Working Principle UV flame detector captures ultraviolet radiation emitted by flame and generates weak electrical signal. The EG1033AC01 amplifies this low-level signal and filters noise. The internal comparator evaluates signal amplitude against preset threshold. When flame signal exceeds threshold, the module activates flame-present relay output. If flame signal drops below threshold for preset time, the module de-energizes relay to send flame failure trip signal to burner safety controller. Built-in self-test circuit checks amplifier circuit integrity continuously.
Installation Requirements
- Install on DIN rail inside burner control cabinet.
- Use shielded twisted pair cable for flame detector sensor wiring.
- Keep sensor cable routed away from high-current ignition cables.
- Apply correct AC supply voltage matching module rating.
- Adjust flame sensitivity during burner commissioning.
- Perform flame simulation test to verify flame failure trip function.
- Complete cabinet protective earth connection.
Usage Notes
- Do not run flame sensor cable alongside high voltage ignition wiring.
- Keep cabinet free of dust and oil contamination.
- Perform periodic flame test and self-test as part of BMS safety procedure.
- Replace UV detector tube when signal strength drops significantly.
- Do not modify internal amplifier circuit.
- Disconnect power supply before removing module.
- Verify relay contact integrity during routine maintenance.
