Spirax-Sarco Boiler Level Controller LC3050

The Spirax Sarco LC3050 is a level limiting alarm for use in conductive liquids as a high or a low alarm, and is defined as a 'special design water level limiter' in the context of EN 12952-11. It is suitable for use with steam or hot water boilers operating up to 32 bar at 239°C. The LC3050 is a dual voltage unit, 230 Vac or 115 Vac for use with Spirax Sarco high or low level, self-monitoring high integrity probes. The LC3050 has two LED’s, indicating normal and alarm conditions, and a test button (AL). The other buttons on the keypad are non-functional. The unit can be panel, DIN rail or chassis mounted. An automatic cyclic test of the probe, probe cable and controller is carried out every few seconds by internally simulating a fault in the probe. A test button is fitted so that a full test of the probe, controller, and associated circuits can be carried out. Provision is made for the wiring of a remote test button if required. WARNING; In most countries, steam boilers operating with limited supervision require two self-monitoring level probes and controllers to provide two independent low level alarms. A high level alarm is also advised, and is compulsory in some countries. Principal features: High integrity, self-monitoring low or high level alarm. Dual mains supply, 230 / 115 Vac. TüV approved. LED indication of status. Infrared communications
