DOCN601 Series Dissolved Oxygen analyzers/controllers are a rugged and dependable industrial grade microprocessor-based instruments that is extremely easy to use.
Its large, bright LED digital display is clearly visible even in direct sunlight. It’s speedy calibration and simple operator interface makes this analyzer/controller a favorite with instrumentation departments in a wide variety of demanding industrial and municipal applications. Frequently used functions are accessed through an intuitive step-through menu which is printed directly on the front panel for ease of navigation. By pressing the MENU key the operator scrolls 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 accepts a sensor input from the DOE-601 sensor. The DOE-601 sensor consists of a probe that is fitted with a DOE-601-SC cartridge containing a precisely stretched permeable membrane, electrodes and electrolyte. The inexpensive and easy to change cartridge takes only minutes to replace. The cartridge is hermetically sealed. Optional mounting hardware includes submersion and “ball float” assemblies.
Calibration can be accomplished by using one of seven different calibration 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 illuminates. Use the arrow keys to set the value determined using a calibration method described above. Press The Enter key twice. The unit is now calibrated.
The DOCN600 Series provide three analog outputs, including a 4 to 20 mA, 0 to 5 Vdc and 0 to 1 mA. The instrument also provides control of external devices using its two independent control 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 also illuminates to clearly 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.
A self-diagnostics program clearly indicates any system errors or faults by turning the STATUS LED on the front panel from green to red. The operator then scrolls through the menu to STATUS to determine the fault code. The Operator’s Manual indicates the source and likely remedy for the fault. When the status fault is corrected the STATUS LED will turn back to green.
DOCN600 Series is packaged in a rugged NEMA 4X fiberglass reinforced polyester enclosure. It is ideally suited for heavy-duty outdoor applications such as municipal and industrial wastewater.
