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).

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. measurement.
• Fittings and mountings must be capable of carrying the sensor's weight
(0,77 kg / 1.7 lbs), and vibrations from for example pumps and other
equipment must be avoided.
• The system should be installed to facilitate access to the Oxix® transmitter
operator panel and sensor without risking personal injury during normal
operation, maintenance, cleaning of sensor, etc.
• The Oxix® transmitter must be connected to a mains outlet that complies
with national and local regulations.
• All cables must be installed, connected and mounted to minimize mechanical impact and electrical influence from other installations.
• The sensor cable’s maximum tensile load is adjusted to the sensor weight.
• The sensor is a electro-mechanical instrument. Be careful not to damage
the sensor lens. The accuracy will deteriorate if foreign material accumulates on it, or it is subject to abrasive cleaning procedures. Only use a soft
cloth for cleaning. NEVER EVER a steel brush!
• All fuses are located on the Oxix® converter’s motherboard.

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.
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 significant depth fluctuations. The dissolved oxygen saturation varies with
the depth.

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.
3. Lower the sensor into the solution and let it rest at least half an hour.
4. Make sure that the sensor's measuring element is facing down, and no air
bubbles stick to the lense.
5. Check that the the Oxix® readout is zero.
2-point Calibration
2-point calibration is normally not required and is not recommended.
For very special applications it is possible to perform a 2-point calibration of
the Oxix® transmitter. If required, contact an MJK sales or service representative for further details.

8. Startup
Initial Checks before Power-up
Before switching on power the following steps must be checked.
1. The local mains power supply voltage corresponds to the voltage printed
on the identification label of the transmitter.
2. All electrical connections are made in accordance with the electrical connection diagram shown with special emphasis on the sensor connection
described on page 30.
3. All terminal screws are tightened.
4. All cable glands are tightly secured.
5. All grounding connections are made in accordance with the instructions in
this manual (see page 21).
Initial Power-up
1. Turn on power.
2. Within 60 seconds the Oxix® sensor will be found by the automatic sensor detection program. During this process you might briefly see "SuSix1"
and/or "MagFlux1" on the display. This is normal and to be expected.
Initial Measurement
1. Make sure that the sensor is completely covered by liquid.
2. Turn on power to the transmitter and wait 15 minutes before taking the
initial measurement.
Language Selection
1. The default display language is English. If another language is required,
proceed with step 2.
2. Select "Display Setup" from the Main Menu.
3. Select "Language" from the Display Setup menu and chose the required
language (see page 73).

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.

Dissolved Oxygen Transmitter
The data log contains:
• Date
• Time
• Dissolved oxygen values
In case of a power failure, the data logger continues when power returns.
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.

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® sensor into the liquid to be measured and leave it for at
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.
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.
