Features & Benefits S 24V DC power supply requirement w/ optional 240V AC power adapter S 4.3in LED full color touch display (480 x 272p) w/ four tactile function keys human machine interface (HMI) included for operator controllability (24 VDC) S 7.0in & 10.4in LED touch displays (800 x 480p / 800 x 600p) w/ out tactile function keys available S Memory storage capability of up to 20,000 commands, can add multiple audible alarms, indicator lights for running status, faults, specific process commands etc. to compliment or modify base RO System function programming S Login/Logout access provided upon request from Excalibur if a sensor setpoint or input must be changed by the operator, otherwise settings are locked out for safety purposes S Display operating hours on HMI S Communication ports: USB 2.0 (non-isolated) RS232/RS485 non-isolated combo serial 10/100 Base T Ethernet port (RJ-45) - Unit can be connected to 3rd party devices and building management systems S Operational Temperature Range: -20° to 65°C (-4° to 149°F) S 24 Input/Outputs (14 Input Channels/10 Output Channels) All Digital S 8 Analog inputs enabled through plug-in modules to support pH sensors, conductivity sensors, flow sensors, tank level sensors relaying information to the unit and allowing it to display readings on the HMI S 1 pH sensor, 2 conductivity sensors, 3 flow sensors (Inlet/Permeate/Waste), 1-2 tank level sensors S Low tank level detection automatically triggers system operation (if not already operating), high tank level detection triggers system standby S Fault detection program included for pH levels, Feed TDS levels, Permeate TDS levels, and high/ low pressure conditions. The Micro850 stops the system when these are detected and will attempt to return to operation 3 times before locking out and requiring a physical reset by the operator. S Manual bypass for pH, Feed/Permeate TDS, and high/low pressure sensors + faults included in program for troubleshooting/maintenance purposes S Inlet valve solenoid and motor control tied to Micro850 for safety; if any faults are detected the controller will shut these off. S Auto-flush built into program requiring no manual input from an operator S Visual operational status of motor, inlet valve, and bypass valve is viewable from the HMI along with TDS levels for both Feed and Permeate updating continuously every second on a digital graph S Inputs from sensors allow for volume recovery %, rejection %, concentration factor, and flux to be displayed on the HMI MICRO850 PLC – INTELLIGENT REVERSE OSMOSIS SYSTEMS
