LCS1350 Level Switch
Description The LCS1350 level switch can be used in conjunction with an LP10-4, LP11-4 or LP41 conductive level probe as an interval level control system in pressurised steam and hot-water plants and in condensate and feedwater tanks. The LCS1350 level switch also indicates two alarm states, which can be configured as MIN or MAX.

The LCS1350 level switch measures using the conductivity principle and makes use of the electrical conductivity of the water to do this.
The level switch is designed for use with various conductive liquids from salt solutions or boiler water to condensate having an electrical conductivity as low as 0.5 μS /cm at 25 °C. The level switch operates as an interval level control system (inlet/discharge configurable by code switch), and also indicates when the water reaches two independent alarm states, which can be configured as MIN or MAX. The switchpoints for water level control and for the MIN or MAX levels are determined by the length of the respective probe tips. Up to four probe tips can be connected. For water level control, the level switch recognises whether the probe tips are immersed or out of the water and, depending on which function is set, it switches the switch output contact, which then turns the feedwater pump on or off, for example. The Pump LED lights up when the level switch has switched the feedwater pump on, for example.
Alarm and fault indications are displayed by LEDs.
Directives and standards VdTÜV Bulletin BP WASS 0100-RL
The LCS1350 level switch, in combination with the LP10-4/LP11-4/ LP41 level probes, is type approved to the VdTÜV Bulletin "BP WASS 0100-RL". The VdTÜV "BP WASS 0100-RL" describes the requirements for water level control and limiting equipment. LV (Low Voltage) Directive and EMC (Electromagnetic Compatibility) RoHS (Restriction of Hazardous Substances) The equipment conforms to the requirements of the Low Voltage Directive 2014/35/EU, the EMC Directive 2014/30/EU and the RoHS Directive 2011/65/EU. ATEX (Atmosphère Explosible) The equipment must not be used in potentially explosive atmospheres, in accordance with European Directive 2014/34/ EU.
