Dissolved Oxygen Transmitter 1. Introduction Thank you for choosing the MJK Oxix® Dissolved Oxygen Transmitter.
Dissolved Oxygen Transmitter About this Manual This manual is divided into one table of contents, eleven chapters, five appendices, four continuous menu overview flow charts and one index. 1. Introduction Contains a presentation of the Oxix® Dissolved Oxygen Transmitter, the structure of this manual, the operating principles and the top features. 2. Safety, Repair and Product Identification Provide answers to issues regarding safety, mounting, repair, restrictions and product identification. 3.
Dissolved Oxygen Transmitter Appendix A. Pop-up Events / Error Messages Lists possible pop-up messages, explains their meaning and offer solutions to error conditions. Appendix B. MJK-Field Link Software Upgrade Describes in detail how to utilise the unique and intuitive MJK-Field Link software program to upload new display and converter firmware versions. Appendix C. Front Panel Cut-out Drawing A 1:1 scale drawing of the front panel outline and cut-out area for installation and mounting purposes.
Dissolved Oxygen Transmitter Operating Principles The MJK Oxix® Dissolved Oxygen Transmitter is designed for measuring the oxygen contents in open tanks exposed to sunlight, wells and closed containers. The Oxix® sensor function is based on the fluorescence principle and does not consume oxygen like membrane-type sensors. It is rugged and designed to handle tough applications. Light pulses with a wavelength of 475 nm are transmitted to a ruthenium compound immobilized in a sol-gel matrix.
Dissolved Oxygen Transmitter Features Flexible Installation MJK’s modular design allows up to 300 meters (950ft.) between the sensor and the converter, and the Display Unit can be mounted up to 1000 m (3000 ft.) from the signal converter with ordinary twisted wires. 1 pc. Oxix Converter with display ( 206505 ) ll RS485 3 pcs. Oxix without display (206508) ll RS485 ll RS485 Max. 300 m 4 pcs. Oxix sensors (206510) Max.
Dissolved Oxygen Transmitter Flexible In- and Outputs The Oxix® Transmitter has one 4-20 mA analogue output, two digital outputs for alarms or control, and one digital input for resetting alarms, batches, etc. User-definable Text Up to five lines of text and readings can be configured by the user. The graphic display is automatically adjusted to show the largest characters possible. Alarms can be displayed as pop-up alarms until they are reset.
Dissolved Oxygen Transmitter 2. Safety, Repair and Product Identification Safety Instructions • Read this manual carefully. • Pay attention to the environment on the installation site. • Wear necessary protective equipment and follow all current safety regulations. • Oxix® can invoke a start signal for dangerous machinery.

Dissolved Oxygen Transmitter 4. Sensor Installation WARNING! The Oxix® transmitter must not be powered until the transmitter is correctly mounted and connected! WARNING! Connections to the Oxix® transmitter must not be disconnected while the transmitter is powered. Important! To ensure safe and optimal functionality of the Oxix® transmitter, the instructions below must be followed closely. • The sensor must be mounted in a location where it is possible to perform a representative dissolved oxygen sat.
Dissolved Oxygen Transmitter Physical Sensor Installation Preparation Select a position that can produce a valid and representative measuring value and provide sufficient space for physical cleaning of the sensor on a regular basis. Positioning the Sensor The positioning of the sensor is very application dependant. There are, however, some "do"s and "don't"s that can be used as guidelines.
Dissolved Oxygen Transmitter 5. Sensor Calibration The Oxix® sensor is factory calibrated. No further calibration is required. Zero-point Calibration Check A zero-point calibration check may be carried out as described below. Required materials • 1 bucket • 1 measuring cup • 1 tablespoon • Sodium sulfite (Na2SO3) Procedure 1. Dissolve 3 tablespoons of sodium sulfite ( Na2SO3 ) in a bucket (or open container) containing 4 liters of clean tap water (1 US gallon, 0.9 UK gallon). 2. Stir for about 1 minute.

Dissolved Oxygen Transmitter lay OK A typical cleaning interval for aeration basins would be 2 hours (120 minutes). In colder climates, condensation may form and then freeze in the tubing. This can be prevented by setting the interval to 5 - 20 minutes. The cleaning time would typically be 30 seconds. The measurement delay (recovery time) may also be used to coordinate with other processes. The delay merely freezes the last reading before cleaning begins. A typical value would be 60 seconds.
Dissolved Oxygen Transmitter High alarm A set point can be set to trigger an alarm (here: a high alarm) and to activate one of two relays or simply to display the alarm on the display.
