Open Source Software (OSS) declaration Due to the license terms of the software we use, Siemens AG wishes to note that the OEM is obligated to provide the following license text for the end user in the documentation: Open Source Software (OSS) declaration Embedded in – or bundled with – the LMV6 are open source software (OSS) components and other third-party components identified below. You will find the specific product type and the valid version in the OSS document. Title: Readme_OSS System LMV6 V01.
Lifetime The LMV6 has a designed lifetime* of 250,000 burner startup cycles which, under normal operating conditions in heating mode, corresponds to approx. 10 years of service (starting from the date of manufacture on the nameplate). This is based on the endurance tests specified in the EN 298 standard. A summary of the conditions has been published by the European Control Manufacturers Association (Afecor) (www.afecor.org).

Technical data Basic unit LMV6 Mains voltage 230 V AC -15% / +10% Mains frequency 50 Hz 6% External primary fuse (Si) Max. 6.3 A, slow Caution! Risk of damage to the switching contacts! If the external primary fuse (Si) or internal fuse (F1) is blown due to overload or short-circuit at the terminals, the LMV6 must be replaced.
Technical data (continued) Terminal loading: Inputs Mains supply: The input current for the power supply is dependent on the operating status of the LMV6 Rated voltage UMains 230 V Safety shutdown from the operating position at mains voltage ≤ 185 V AC Restart is initiated when mains voltage exceeds ≥ 195 V AC Status inputs (with the exception of the safety loop) of the contact feedback network are used for system supervision and require mains-related input voltage Safety loop Refer to Term

Technical data (continued) Flame supervision with QRA2 / QRA2M / QRA4 / QRA10 Caution! If QRA2 / QRA2M / QRA4 / QRA10-UV tubes are used for flame supervision on the LMV6, it must be ensured that the LMV6 is permanently connected to power (EN 298), thus enabling the LMV6 to detect flame detector failures during startup and shutdown. The LMV6 generally operates with QRA flame detectors in intermittent operation.
