DOCN600 Series dissolved oxygen analyzers/controllers are rugged and dependable. The large, bright LED digital display is clear even in direct sunlight. Speedy calibration and simple operation make these microprocessor-based instruments suitable for a wide variety of demanding industrial and municipal applications. An intuitive step-through menu gives the user access to functions directly from the front panel. By pressing the MENU key, the operator can scroll through the menu, illuminating an LED beside the selected item and displaying the stored value. Arrow keys are used to change the value. Seldom used or set-once adjustments, such as password activation, are located on DIP switches on the back of the swing-out front panel. The DOCN600 Series instruments accept the DOE-601 mounting assembly fitted with a DOE-601-SC sensor cartridge containing a precisely stretched permeable membrane, electrodes, and electrolyte. The inexpensive, easy-to-change cartridge is hermetically sealed. Optional mounting hardware includes submersion and “ball float” assemblies. Calibration can be achieved with 1 of 7 techniques: in the process to a portable meter; in clean water to a portable meter; in a process sample to a lab meter; in a clean water sample to a lab meter; in a saturated process; in saturated clean water; and in air. To calibrate, press the MENU key until the CALIBRATION LED DOCN601 shown much smaller than actual size. lights up. Use the arrow keys to set the value, determined with one of the above calibration methods. Press the ENTER key twice. The unit is now calibrated. The DOCN600 Series provides 3 analog outputs: 4 to 20 mA, 0 to 5 Vdc, and 0 to 1 mA. The instrument can also control external devices with its 2 independent relays. An alarm relay has both high and low setpoints with a fixed deadband. When this relay is energized, the ALARM LED on the front panel illuminates to indicate an alarm condition. Factory-set for bidirectional control, both control relays can be set to control either a rising or falling process, with easily programmed Relay On and Relay Off setpoints. Our Dissolved Oxygen Instrumentation product line continues to expand, visit omega.com for new details! A self-diagnostics program indicates any system errors or faults by turning the STATUS LED on the front panel from green to red. The operator then selects STATUS from the menu to determine the fault code. The operator’s manual indicates the source and likely remedy for the fault. When the fault is corrected, the STATUS LED will turn back to green. DOCN600 Series instruments feature a rugged NEMA 4X fiberglass-reinforced polyester enclosure. They are ideal for heavy-duty outdoor applications, such as those involving municipal and industrial wastewater.
