LC2650
Level controller
Description
The Spirax Sarco LC2650 is a level controller for conductive liquids.
It provides on/off or modulating control of liquid levels in boilers, tanks, and vessels operating up to 32 bar at 239 °C.
It has two alarm channels that can be independently configured either high or low.
The controller is suitable for use with liquids having an electrical conductivity as low as 5 μS/cm or 5 ppm (when used with an LP20,
PA20 or PA420 capacitance probe).
The front panel has an LCD screen and a five-button keypad. The LCD display screen can show either operating information (in run
mode), or a trend graph that displays a record of the variation in level over a set time.
In run mode the general data is shown on several consecutive screen displays.
A test function provides the operator with a diagnostic feature.
Inputs can be measured and outputs can be set from the front panel.
To prevent unwanted or inadvertent changes being made, all commissioning parameters are protected with a pass code.
The LC2650 can communicate via an infrared link between adjacent controllers.
It can be designated as either a master unit or a slave unit.
The LC2650 can be panel, DIN rail or chassis mounted.
