Installation, initial start-up and maintenance may only be performed by trained personnel! All applicable
European and national regulations regarding installation of electrical equipment must be adhered to.
The device may only be connected to supply power which complies with the specifications included in the
technical data and on the serial plate!
The device must be disconnected from all sources of power during installation and maintenance work!
The device may only be operated under the conditions specified in the operating instructions!
Functions Description:
The turbidity measuring device determines the turbidity of liquids using the light absorption and scattered light
measuring method.
The inline measuring cell at the sensor set makes use of two IR transmitters and one IR receiver in pulsating light
mode (IR measuring method according ISO 7027).
The interconnected BAMOPHOX TUR measuring amplifier analyses the 4 to 20 mA signal generated by the sensor
set.
Installing the Sensor Fixture:
Observe:
The fixture must be installed vertically!
Best installation is the mounting in a ascending tube with slow down section 600 mm in front and 400
mm behind the turbidity measuring device
The sensor fixture must be completely filled with liquid medium during the performance of measurements.
Install to the vertical portion of a siphon trap if necessary.
Air bubbles distort measurement results.
Glasses must be clean – clean at regular intervals as required.
Safety Precautions:

The sensor set consists of a receiver module with microprocessor-controlled analysis electronics and two
transmitter modules.
The sensor set generates a 4 to 20 mA output signal in accordance with the following diagram.
Measuring ranges are selected with the help of the DIP switches on the receiver module.

Troubleshooting:
Measuring current 22 mA = overflow
Measuring current 0 mA = wrong DIP-switch setting (no valid measuring range selected)
Indication
green LED = 1 Hz blinking ready, measuring in operation
green LED = permanent ON ready, measuring not in operation
green LED = OFF no power supply or defective
Fault indication
red LED = ON = measuring circuit faulty, (short circuit or broken)
red LED = 1 Hz blinking
only TURBICUBE 20 = glasses dirty or liquids to much colorized (damping factor > 20 dB)
Note:
The turbidity measuring instruments are calibrated with the internationally specified standard suspension Formazin. The indication takes place
thus not in form of the measured light intensity, but as concentration of the Formazin calibration suspension. During the measurement of any
liquid this means thus that the liquid concerned causes the same light scattering as the standard suspension of the indicated concentration.
Measured values of other turbidity measuring instruments, which use other calibration suspensions and measuring angle, cannot be compared
directly with those with Formazin calibrated measuring instruments!

Receiver Module PCB
Elektrical Connection:
Observe:
The measuring output “4-20 mA" is a current drain, that means,
the output channel has the same electrical behavior as a variable resistor.
A active power supply for the measuring circuit is always needed.

Maintenance:
Cleaning intervals depend upon the type of liquid medium and must be determined by the user.
Cleaning the lenses:
Disconnect the turbidity-measuring instrument from all sources of power.
Depressurize pipes and empty liquid medium from the device.
Remove the transmitters and the receiver from the fixture by unscrewing the sleeve nuts.
screw the ETR-glasses with the
included tool and remove. clean the lens – do not use abrasive cleansers,
which may cause scratching!!
tighten the ETR-glasses with the included tool .
Before reinstalling the transmitters and the receiver, refill the fixture with liquid medium and inspect for
possible leaks.
Observe positioning of hole and pin!
Observe for cold fluids
The fixture has to be installed to the pipelines with mounted sensors only
For cleaning the glasses dismount the complete fixture, after cleaning install as described above
Note:
Inspect the O-ring before reassembly
and replace if necessary.
mount the o-ring approximately as
shown in the picture

Testing and Readjustment
Factory Calibration
The sensor set is equipped with a calibration constant as a design feature.
As a rule, no recalibration is required.
Calibration point accuracy is better than 2%‚ and drift is less than 1% per year.
Test Equipment Monitoring
If device calibration testing is required as part of the respective quality assurance system for test equipment
monitoring, calibration can be checked with the calibration rods, and the device can be readjusted if necessary.
A suitable calibration standard is delivered with each turbidity measuring instrument.
Each calibration standard is matched to the specific circumstances of the mating turbidity measuring instrument,
and cannot be used for other measuring instruments of the same type!
The calibration standard and the turbidity measuring instrument must have the same serial number!
Calibration box with mounting tool and calibration rod for TURBICUBE 20
(for TURBICUBE 1000 there are two rods in the box)

Attention:
It must be assured that all utilised control and switching devices are switched off during recalibration!
Procedure for TURBICUBE 20:
The following adjustment sequence must be adhered to!!
Clean all lenses and wipe them dry (all visible water droplets and water film must be removed!).
Then reinstall the lenses for the receiver and the S1 transmitter only.
Do not yet install the lens and the compression disc for the S2 transmitter (180° scattered light)!!
Reinstall the S1 transmitter and the receiver.
Remove the KN 20 calibration rod from the box.
Insert the calibration rod into the fixture
Mount the S2 transmitter to the calibration rod (observe the locking pin)
Insert the calibration rod with attached transmitter completely into the fixture (observe the locking pin),
and tighten the sleeve nut.
Set the DIP switches to the MB5 range = 0,01 to 20FNU (ON/ON/ON/OFF/OFF/OFF)
Switch supply power back on again – the status LED blinks!
Compare the setpoint value and the actual value.
Setpoint 1 (SW1) = setpoint on the plate in the box of the KN20 calibration rod
Actual value = measured value
Setpoint / actual value deviation:
Less than ±5% measuring instrument is OK
Greater than ±5% adjust actual value with potentiometer P4
remove transmitter and calibration rod
mount glass with sealing ring and compression disc and transmitter S2
mount glass with sealing ring and compression disc and transmitter S2
select the right DIP-switch setting for operation
