Multi Channel Controller – LQ800
The Model LQ800 Multi Channel Controller provides a complete analytical measurement and process solution. The LQ800 Multi Channel Controller is designed to operate with up to eight digital analytical and process sensors. The measurement parameters include well over 50 unique separate liquid measurement sensors. These measurement include: pH, ORP, Conductivity, Resistivity, Dissolved Oxygen, Selective Ion, Turbidity, Flow, Level, and many others in varying configurations for a given application. A complete list is found in the LQ800 brochure. The LQ800 Controllers digitally communicates with any ECD Intelligent Sensor, automatically configuring the controller’s menus and display screens to the measured parameter.
SENSORS – The Model S80 Family of Intelligent Sensors facilitate two way communication with the LQ800. The type of sensor, identity and serial number are stored in the sensor’s memory along with calibration registers. Sensors are calibrated at the factory so they are ready to use when connected, are waterproof and submersible with all internal components epoxy encapsulated inside the housing and have various process fittings and configurations.
DISPLAY & INTERFACE- The LQ800 Multi Channel Controller features a large easily viewed color touchscreen display. The display and interface can be Web Enabled with remote monitoring and activation with personal handheld devices and computers with access via the Web.
MENUS – Menu navigation is intuitive and accomplished using the large touchscreen display. The primary selections are the Multi-Channel Main Display, Single Channel Detail Screen, Calibration Menu, Configuration menu, Info Screens and Simulate menu.
CALIBRATION – The ECD S80 sensors come pre-calibrated from the factory. Field calibrations are easily performed with the LQ800. The Calibration menu includes the Auto Cal function, a two point calibration, the Standardize function, a single point calibration or the Manual Calibration, where previously determined Offset and Slope values are entered manually into the LQ800.
CONFIGURATION – The Configuration menus allow the Display and Output functions and the sensor’s characteristics to be configured or adjusted. Display screens include the Hold function, Graphical Display Style, Back Light and Contrast adjustments, Labels/Tags for naming the transmitter, Password Protection and a Factory Default reset. Output screens include setting the digital comm output, setting the 4-20 mA Ranges and fault settings and configuring the Alarm Relays.
POWER SUPPLY and OUTPUTS – The LQ800 is available as a 24 VDC or 100/240 VAC powered controller. Available options include: (8) 4 to 20 mA outputs, (8) configurable Relays (for Alarm, activated timers, control, and Fault), and Ethernet communication.
