Description
The LME73 flame safeguard is designed to pair with the Siemens SQM4 or SQM5 actuator. Having the actuator paired to the LME73 flame safeguard is beneficial for the following applications: packaged burner or when using a ratio regulator. The benefit of having the actuator paired to the LME73 flame safeguard is that the LME73 will drive & prove the actuator position for purge & ignition using closed loop control. Modbus communication module and remote display options available.
Benefits:
- Drive & prove Siemens actuator open for purge & closed for ignition
- Safety interlocks wired independently into unit for specific fault indication
- Built in display showing fault indication and flame signal strength
- Configurable safety parameters to fit your application
