LCSR5000 Level Control Systems
Installation and testing of self-monitoring low level alarms on/off boiler water level controls Typical installation The Spirax Sarco LCSR5000 series boiler water level control systems are suitable for automatically controlled steam boilers and provide the control and alarm functions specified by Standard BS EN12953 and in the BG01 which is a joint document by the CEA and SAFed, originally produced in consultation with the HSE. The LCSR5000 series low level alarms are of the high integrity type and whilst a competent boiler operator should check the boiler plant daily, he need not be on site at all times. There should, however, always be someone available on site who is suitably trained to respond to alarms and take appropriate action. The level controls and level alarms are probably the most important controls on the boiler for ensuring safety and should only be installed and maintained by suitably trained personnel. Spirax Sarco can install, commission and provide a regular maintenance service. For details of installation, wiring and maintenance see the Installation and Maintenance Instructions of the individual components of the system.
