EVITA® OXY sensors are used for measuring
the concentration of dissolved oxygen in water
– especially in controlling and monitoring aeration
processes in wastewater treatment plants, but also
in applications such as fi sh frarms.

OXY 4100 transmitter and a USC Universal Signal
Converter.
There are two versions of the transmitter – a ball
fl oat version, OXY 4100, and a probe version, OXY
4150/3150. The operating principle is identical for
both versions.
There are three versions of the USC - a USC 5000
basic version, and a USC 6000 with added features,
both point to point. A USC 7000 with HART
multidrop functionality enabling up to 15 transmitters
on only two wires.
The EVITA
the oxygen meter. The transmitter converts the
measurements by the sensor into a current signal
and at the same time also performs the necessary
calculations/corrections. The signal converter is the
display and programming unit and offers additional
outputs.
OXY consists of an OXY 1100 sensor, an

Mounting on a handrail
The mounting bracket for OXY 4100 and 4150 can
be mounted directly on a handrail using the supplied
hose clips. Retighten the hose clips after a few
days use to ensure a tight mounting of the mounting
bracket.
In case of strong sideways forces, the PVC pipe
should be mounted with supporting wires. This takes
up some of the sideways mechanical forces on the
pipe and avoids cracking of the mounting bracket.

Calibration
EVITA® OXY sensors must be calibrated in
atmospheric air. Calibration every 6 months is
recommended. Calibration can be initiated from the
USC 5000/6000/7000 or by using the TILTCAL
feature in the OXY transmitter. During calibration,
the OXY 1100 sensor must not be exposed to direct
sunlight.
TILTCAL
®
®
Before calibration, the OXY 1100 sensor must
be cleaned, see section “Maintenance”. With fast
calibration in atmospheric air a 1% system accuracy
can be obtained. Temperature and barometric
pressure compensation is made automatically
during calibration via an internal temperature and
pressure sensor.
Using TILTCAL®
Hold the transmitter with the OXY 1100 sensor
upwards to initiate calibration by activating the tilt
switch. After 5 min. turn the transmitter with the OXY
1100 sensor downwards and the transmitter has
completed the calibration routine. During calibration,
the current output signal is factory set to 4 mA.
Optional 20 mA or the last measured value (Hold)
can be chosen via the USC 5000/6000/7000.
Fig. 40
Tilted Not tilted
31
32
If during the 5 minutes calibration period the
transmitter is turned with the OXY 1100 sensor
downwards, calibration stops and measurements
continue with the previous calibration value.
Temperature compensation is made automatically
during calibration via an internal temperature sensor.
In addition, using factory settings, compensation
is also made for air pressure, relative humidity
and salinity. These factory-set values can be
changed via the USC signal converter or via HART
communication.
USC 5000/6000/7000
calibration
®
Using the USC 5000/6000/7000
In operator menu use the key to select the
“Calibration” menu and press the key to initiate a
calibration.
Compensations for relative humidity and salinity can
be made by entering these values using the USC
5000/6000/7000, see fi g. 48, p. 37.
* See “Advanced settings, fi g. 48, p. 37.
The set values and the signifi cance of deviations
from them are given in appendix I.
A system accuracy of 0.5 % can be achieved by
lifting the transmitter out of the medium and placing
it with the OXY 1100 sensor downwards for 1 hour
to make sure the sensor is completely stabilised.
Calibration can then be initiated.
Fig. 41
Maintenance
Under normal conditions, the OXY 1100 sensor will
operate for 2-3 years and can be replaced in a few
minutes.
General maintenance of the EVITA® OXY sensor
is limited to cleaning about every 2-3 months and
calibration about every 6 months.
Cleaning (OXY transmitter)
During cleaning, the sensor must not be allowed to
remain pointing upwards for more than 3 minutes at
a time if the TILTCAL
a calibration cycle will start. The TILTCAL
can be disabled according to fi g. 48, p. 37.

1. Lift the transmitter out of the medium.
2. Clean the sensor with pure water, to which a little
cleaning agent/washing-up liquid can be added.
3. Dry the sensor with a soft cloth.
4. Immerse the transmitter into the medium to be
measured.
Cleaning (USC signal converter)
When considered necessary, clean the USC signal
converter using a soft moist cloth.
Replacement of sensor
1. Remove the defective/worn sensor.
2. Insert new sensor (see fi g. 7, p.8 or fi g. 8, p. 9).
3. Reset the lifetime counter (see p. 18 or fi g. 32, p.
22).
4. Place the transmitter so that the OXY 1100
sensor points downwards. Keep it in this position
for at least 1 hour to allow the new sensor to
stabilise (see fi g. 29, p. 18).
5. Perform calibration (see section “Calibration” p.
31-32).

“Transmitter address” has to be 0 for current output
to function in a point-to-point installation using USC
5000 or 6000. When operating in multidrop system
using USC 7000, the transmitter must have a
unique address between 1 and 15.

HART
®
The OXY 4100/4150/3150 offers additional
features which can be accessed through the
USC 5000/6000/7000 signal converter or HART
communication. To use HART® communication it
is necessary to use a PC or PLC with a HART
modem and associated software.
All Universal Commands are fully implemented, as
are the necessary Common Practice Commands,
but to ensure complete utilisation of the transmitter,
special Device Specifi c Commands are used.
®
HART
communication makes it possible to read off:
· oxygen concentration
· temperature
· remaining lifetime of the OXY 1100 sensor
· alarms
· indication of completed calibration
®

The USC 5000/6000/7000 can act as either a primary
master or a secondary master. This can be set as
shown in fi g. 51.

Warranty, liability and complaints
56
HACH LANGE GmbH warrants that the product supplied is free of material and manufacturing defects
and undertakes the obligation to repair or replace
any defective parts at zero cost (no guarantee of
quality or durability).
At variance with our general terms and conditions,
the warranty period for the EVITA series instruments
is 12 months.
EVITA INSITU/ EVITA INLINE: On the conclusion of
a system care contract within 6 months of purchase,
the warranty period is extended based on the terms
in the system care contract. HACH LANGE GmbH
offers various system care contracts with different
services and warranty period extensions.
With the exclusion of the further claims, the supplier
is liable for defects including the lack of assured
properties as follows: all those parts that, within
the warranty period calculated from the day of
the transfer of risk, can be demonstrated to have
become unusable or that can only be used with
signifi cant limitations due to a situation present prior
to the transfer of risk, in particular due to incorrect
design, poor materials or inadequate fi nish will be
improved or replaced, at the supplier’s discretion.
The identifi cation of such defects must be notifi ed to
the supplier in writing without delay, however at the
latest 14 days after the identifi cation of the fault. If
the customer fails to notify the supplier, the product
is considered approved despite the defect. Further
liability for any direct or indirect damages is not accepted.
If instrument-specifi c maintenance and servicing
work defi ned by the supplier is to be performed
within the warranty period by the customer (maintenance) or by the supplier (servicing) and these
requirements are not met, claims for damages due
to the failure to comply with the requirements are
rendered void.
HACH LANGE is not responsible for any indirect
or consequential damages, e.g. injuries or damage
to property, failure in operation, including loss of
production, loss of profi ts, loss of goods in stock or
similar that could result from defects and/or delayed
delivery of products sold, irrespective of the cause
including faulty manufacture, design and materials.
Furthermore, the warranty does not include:
- Wearing parts and consumables
- If the product is damaged because it was not
operated/maintained in accordance with the
manual
- If the product is damaged due to incorrect installation or operation
- Damage caused by electrical failure or lightning/
overvoltage
- Defects resulting from failure to clean prior to
storage
- Defects due to use outside the specifi cations for
the transmitter
The following points are to be undertaken (even
without a system care contract) by the customer:
- Attention! EVITA INSITU 4100 / EVITA INSITU
2100 / EVITA INLINE 4150:
o The transmitter is to be cleaned with a clean-
ing cartridge prior to every chemical change
- Documentation of the cleaning and maintenance
work performed
- The replacement of a transmitter supplied
- The cleaning, packaging and organisation of the
return of the faulty transmitter to HACH-LANGE
for repair and/or troubleshooting
HACH LANGE GmbH process instruments are
of proven reliability in many applications and are
therefore often used in automatic control loops to
provide the most economical possible operation of
the related process.
To avoid or limit consequential damage, it is therefore recommended to design the control loop such
that a malfunction in an instrument results in an automatic change over to the backup control system;
this is the safest operating state for the environment
and the process.
If not otherwise agreed, the general terms and conditions of HACH LANGE GmbH also apply
