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. The ruthenium absorbs the light energy by changing the outer electron’s ener­gy level. The unstable electron then collapses and returns back to its original energy state and at the same time emits the surplus energy as a photon with a wavelength of 600 nm. This process is also refered to as fluorescing.
When the intensity of the transmitted light pulses is tightly controlled, the amount of fluorescing is predictable and repeatable. If free oxygen molecules are present, the photon energy is absorbed by the oxygen molecules without any light emission, and the amount of fluorescing is consequently reduced (also refered to as fluorescence quenching). It is therefore possible to determine the amount of dissolved oxygen by meas­uring the amount of fluorescence quenching (light intensity).

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.
Do
In • aeration tanks or basins with significant fluctuation in depth the sensor should be mounted on a foating device that keeps the sensor submerged to a fixed depth from the surface.
In tanks or basins with no or little fluctuation in depth the sensor may • be mounted in a fixed position approximately 1/4 below the surface.
The optimal position at installations in flow-through aeration basins with • one measuring point is near the tank inlet.
The optimal positions at installations in flow-through aeration basins • with two measuring points are near the tank inlet and the tank outlet.
Don't
Do not position the sensor at or very close to the surface. Strong wind • aeration leads to increased dissolved oxygen concentration in the sur­face layer which may not be representative.
Do not use a fixed sensor position in aeration tanks/basins with signifi-• cant depth fluctuations. The dissolved oxygen saturation varies with the depth.

Changing the Power Supply Voltage 230/115 V AC
To change the input mains voltage from 230 V AC to 115 V AC (or vice versa) proceed as follows:
1. Loosen the four screws on the front and lift out the display (see also page
23).
2. Note down the color and position of the wires in the terminal blocks, and then loosen the terminal screws.
3. Unscrew the two screws that hold the metal cover and then remove it.
4. Unscrew the four screws that hold the mother PCB (the printed circuit board with all the electrical components).
5. Remove the mother PCB and look at the back side. This is what you should expect to see for a 230 V AC configuration:
230 V AC single jumper position
6. Unsolder and remove the jumper indicated by the arrow.

Contrast Adjustment
Adjust the display contrast by pressing the two outmost keys simultaneously (indicated by the keys) and press the up/down keys as required.
Save the new setting by pressing the two outmost keys simultaneously.
System Reset
You can reset and refresh all system displays and key combinations by press­ing all four keys simultaneously. It is a so-called coldboot, where all displays are refreshed and all settings/configurations are kept with only one exception: the language setting.
This feature is especially useful during for example a service call, where the display language (Dutch, Danish, Swedish etc.) cannot be understood by the local serviceperson. A system reset immediately sets the display language to (GB) English.
The system reset must not be confused with the ultimate "Recover factory settings" (see page 60) which deletes all local configurations/settings and replaces them with default factory settings.

If more converters are connected to one Display Unit, each converter has its own individual log interval and can be sorted.
All converters share the same memory of 20.000 entry points.
The log data can be shown on the Display Unit or be stored in an external CSV file. MJK-Field Link software is needed for transfer of data into CSV file format via the USB port in the display unit. The format can be read in for ex­ample Microsoft
®
Excel® (see Appendix D on page 97 for details).
An example of the log capacity of one sensor versus the time interval is shown in the following table.

mA Output
When a Oxix® is connected to a power supply for the first time, the mA out­put is automatically set to provide 4 mA at zero and 20 mA at the theoretical maximum value.
Changes in the mA setting will not affect the relay output settings.
Note: Both values can be set in the range 10 % to 120 %, making it
possible to increase or decrease the mA signal.
The mA output is an active output, and the maximum load is 800 Ohm.
The upper limit for the mA output is 20,5 mA 3,75 mA indicates the mA output is not in use 3,5 mA indicates values under 4 mA level 20,5 mA indicates value higher than 20 mA level.

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.

11. Maintenance

The Oxix® sensor requires no maintenance as such. It may, however, be cleaned on a regular basis to maintain its maximum accuracy.
In very slimy environments the built-in water or air jet function may be used with advantage.
Clean the transmitter for example once a month to begin with, until an optimal cleaning interval can be determined.

Cleaning the sensor

1. Remove the Oxix® sensor from the liquid.
2. Clean the sensor with a soft, moist cloth and clean water. A mild detergent or dishwashing liquid may be used.
Warning: The accuracy will deteriorate, or be completely ruined at the worst, if the measuring optic element is scratched by for example the use of a steel brush during cleaning.
3. Dry the sensor with a soft cloth.
4. Immerse the Oxix least 15 minutes to stabilize the reading.
5. The cleaning intervals may need to be shortened or extended, all depend­ing on the usage, the liquid composition and the location.
®
sensor into the liquid to be measured and leave it for at

Cleaning the converter display

When seen necessary the Oxix® converter display may be cleaned with a soft, moist cloth.

Functional Tests

The Oxix® transmitter calibration can, if wanted, be checked from the serv­ice menu option "Sensor calibration". This option is read-only. In the unlikely event that the unit fall out of calibration, an MJK serviceperson must be called to fix or re-calibrate the transmitter.

Service Contract

A service contract maintains the equipment reliability and accuracy. Get in contact with MJK’s national sales and service representatives.
