2Introduction
EVITA® OXY sensors are used for measuring theconcentration of dissolved oxygen in water –especially in controlling and monitoring aerationprocesses in wastewater treatment plants, but alsoin applications such as fish farms.
EVITA® OXY consists of an OXY 1100 sensor, anOXY 4100 transmitter and a USC Universal SignalConverter.
There are two versions of the transmitter – a ballfloat version, OXY 4100, and a probe version, OXY4150/OXY 3150. The operating principle is identicalfor both versions.
There are three versions of the USC - a USC 5000basic version, and a USC 6000 with addedfeatures, both point to point. A USC 7000 withHART® multidrop functionality enabling up to 15transmitters on only two wires.
The EVITA® OXY 1100 sensor is the heart of theoxygen meter. The transmitter converts measurementstaken by the sensor into a current signal and at thesame time also performs the necessary calculations/corrections. The signal converter is the display andprogramming unit and offers additional outputs.

USC 7000 multidrop systemChange transmitter address from defaultTo allow the USC 7000 to recognise the transmitteron the HART® bus, the transmitter needs a uniqueaddress between 1 and 15. The EVITA® OXYtransmitter is factory delivered with the address 0,which is used for point-to-point installations (USC5000/6000).
To programme a transmitter address, all othertransmitters in the multidrop system need to bedisconnected from the HART® bus. To allow theUSC 7000 to locate the transmitter, press “ScanHART bus”.
Change the address to an address between 1 and15 that is not used by any other transmitter. Re-connect the other transmitters and press “ScanHART bus” to complete the installation.

30Calibration
EVITA® OXY sensors must be calibrated inatmospheric air. Calibration every 6 months isrecommended. Calibration can be initiated from theUSC 5000/6000/7000 or by using the TILTCAL®
feature in the OXY transmitter. During calibration,the OXY 1100 sensor must not be exposed to directsunlight.
Using TILTCAL®
Hold the transmitter with the OXY 1100 sensorupwards to initiate calibration by activating the tiltswitch. After 5 min. turn the transmitter with the OXY1100 sensor downwards and the transmitter hascompleted 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
Before calibration, the OXY 1100 sensor must becleaned, see section “Maintenance”. With fastcalibration in atmospheric air a 1% system accuracycan be obtained. Temperature and barometricpressure compensation is made automaticallyduring calibration via an internal temperature andpressure sensor.
Tilted Not tilted
TILTCAL®
31
If during the 5 minutes calibration period thetransmitter is turned with the OXY 1100 sensordownwards, calibration stops and measurementscontinue with the previous calibration value.Temperature compensation is made automaticallyduring calibration via an internal temperaturesensor. In addition, using factory settings,compensation is also made for air pressure,relative humidity and salinity. These factory-setvalues can be changed via the USC signalconverter or via HART® communication.
The set values and the significance of deviationsfrom them are given in appendix I.A system accuracy of 0.5 % can be achieved bylifting the transmitter out of the medium and placingit with the OXY 1100 sensor downwards for 1 hourto make sure the sensor is completely stabilised.Calibration can then be initiated.
Using the USC 5000/6000/7000In operator menu use the key to select the“Calibration” menu and press the key to initiatea calibration.Compensations for relative humidity and salinitycan be made by entering these values using theUSC 5000/6000/7000, see fig. 48, p. 37.

* See “Advanced settings, fig. 48, p. 37.
32Maintenance
Under normal conditions, the OXY 1100 sensor willoperate for 2-3 years and can be replaced in a fewminutes.
General maintenance of the EVITA® OXY sensor islimited to cleaning about every 2-3 months andcalibration about every 6 months.
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 beadded.
3. Dry the sensor with a soft cloth.4. Immerse the transmitter into the medium to be
measured.
CleaningDuring cleaning, the sensor must not be allowed toremain pointing upwards for more than 3 minutes ata time if the TILTCAL® function is enabled,otherwise a calibration cycle will start. TheTILTCAL® function can be disabled according to fig.48, p. 37.
Replacement of sensor1. Remove the defective/worn sensor.2. Insert new sensor (see fig. 7, p.8 or fig. 8, p. 9).3. Reset the lifetime counter (see p. 18 or fig. 32, p.
22).4. Place the transmitter so that the OXY 1100
sensor points downwards. Keep it in thisposition for at least 1 hour to allow the newsensor to stabilise (see fig. 29, p. 18).
5. Perform calibration (see section “Calibration” p.30-31).

52HART®
The OXY 4100/4150/3150 offers additional featureswhich can be accessed through the USC 5000/6000/7000 signal converter or HART® communication.To use HART® communication it is necessary touse a PC or PLC with a HART® modem andassociated software.
All Universal Commands are fully implemented, asare the necessary Common Practice Commands,but to ensure complete utilisation of the transmitter,special Specific Device Commands are used.
HART® communication makes it possible to readoff:
· oxygen concentration· temperature· remaining lifetime of the OXY 1100 sensor· alarms· indication of completed calibration
When calibrating/replacing an OXY 1100 sensorthe following can be performed with HART®
communication:
- initiation of calibration
- keying in of values for relative humidity, airpressure and salinity for compensationpurposes
- zero setting of life counter
The following programming is possible withHART® communication:
– setting of measuring range
– deactivation of tilt-switch for initiating anautomatic calibration
– setting of current output signal during calibrationfor 4 mA, 20 mA or last measuring value
– deactivation of alarms on current output
– measurement start after completed calibration
– change OXY 1100 sensor type
The USC 5000/6000/7000 can act as either a primarymaster or a secondary master. This can be set asshown in fig. 51.
