LC1350 Level Controller

Transcription

1 LC1350 Controller Description The Spirax Sarco LC1350 has two alarm channels that can be independently configured high or low to control the water level of a boiler, tank or vessel by operating a pump, valve or solenoid. It has been designed as an on/off level controller for use with the LP10-4 four-tip conductivity probe operating on supply voltages from 99 to 264 Vac. The controller is suitable for use with virtually all qualities of conductive liquids from salt solutions or boiler water to condensate having an electrical conductivity as low as 1 μs /cm at 25 C. 77 F) The LC1350 gives accurate and reliable control under the very different conditions found in vessels, tanks or high output boilers operating up to C. 462 F) The front panel has a 3-digit LCD screen and moving segments that the liquid level rising or falling along with a five-button keypad. The unit can be panel, DIN rail or chassis mounted. Principal features: - controller with two configurable alarms. - Universal power supply 99 Vac to 264 Vac. - UL and TÜV approved. - LCD shows level change direction. - Interactive safety feature. - Infrared comms. Approvals This product complies with the Electromagnetic Compatibility Directive 2004 / 108 / EC and all its requirements. The LC1350 is suitable for Class A Environments (e.g. industrial). A fully detailed EMC assessment has been made and has the reference number UK Supply BH LC The LC1350 complies with the Low Voltage Directive by meeting the standards of: - EN :2001 safety requirements for electrical equipment for measurement, control, and laboratory use. The LC1350 has been type-tested as a level control by meeting the standard: - Vd TÜV requirements for water level control and limiting devices, Water 100 ( ). Clamping screw LC1350 LCD Application Pump on Pump off High alarm - Low alarm Typical application example on/off control of a feedtank: Note: probes can be mounted in external chambers if boiler mounting is not possible. Function Inputs The LC1350 input options are: - High alarm or low alarm from a conductivity probe. - Pump on/off control from two conductivity probes. Function / outputs The controller reacts to a change in probe conductivity (open /closed circuit) and energises / de-energises a relay. This action switches a pump or sounds an alarm. Other features: - Additional filters can be selected to increase the damping effect for turbulent conditions. - To prevent unwanted or inadvertent changes being made, all commissioning parameters are protected with a fixed pass code. - The product can communicate via an infrared link between adjacent boiler house controllers. It is designated as a slave unit. - A panel mounted external test switch may be fitted if required.

3 LC1350 Controller Safety information, installation and maintenance Warning: This document does not contain sufficient information to install the unit safely. The unit operates at a potentially fatal mains voltage. Before attempting to install the unit read the Installation and Maintenance Instructions supplied with it. 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. The LC1350 is not selfmonitoring. Do not install the product outdoors without additional weather protection. Do not attempt to open the product - it is sealed and has no replaceable parts or internal switches. Do not cover or obstruct the infrared beam between products. No special servicing, preventative maintenance or inspection of the product is required. water level controls and level alarms do, however, require testing and inspection.
