Information About LAL2.25-110V
The LAL2.25-110V is a member of the Siemens LAL2 burner control family. Its plug-in construction includes a black plastic housing and a sequence-linked lockout indicator. The 110-volt version works with QRB1/QRB3 photoresistive detectors or an RAR9 photocell detector. It is designed for intermittent operation, requiring at least one controlled shutdown every 24 hours.
Key Features:
- Burner Compatibility: Supports multistage and modulating oil atomizing equipment.
- Air Pressure Supervision: Monitors the external air pressure switch during the burner sequence.
- Flame Detection: Accepts compatible QRB1, QRB3, or RAR9 detectors.
- Timed Sequencing: Coordinates purge, ignition, and fuel valve operation.
- Fault Indication: Displays the sequence position associated with lockout.
- Plug-In Construction: Fits a compatible Siemens terminal base for equipment integration.
The LAL2.25-110V delivers the reliability and precision required for supervised oil burner startup and combustion control.
