1 7 106 Ga burner control LME39... Burner control for the uperviion of 1- or 2-tage ga or ga burner of mall to medium capacity, with or without fan in intermittent operation. The LME39 and thi Data Sheet are intended for ue by OEM which integrate the burner control in their product. Ue, feature Ue LME39 are ued for the tartup and uperviion of 1- or 2-tage ga or ga burner in intermittent operation. The flame i upervied by an ionization probe or flame detector type QRA with ancillary unit AGQ3.xA27 for ga forced draft burner. Application in accordance with EN 267: Ga burner for liquid fuel Type-teted and approved in accordance with DIN EN 298 Feature - Undervoltage detection - Air preure uperviion with function check of the air preure witch during tartup and operation - Electrical remote reet facility - Multicolor indication of fault tatu and operational tatu meage - Limitation of the number of repetition - Accurate program equence thank to digital ignal handling - Controlled intermittent operation after a maximum 24 hour of continuou operation - BCI

The ignition (ignition park) can have a negative effect on the ionization current formation during tartup. To minimize the impact the poitioning of the ionization probe mut be checked and optimized it may be beneficial to replace the electrical connection (phae / neutral) on the primary ide of the ignition tranformer A hort-circuit between ionization probe and ground initiate a non-alterable lockout.
