IntroductionIntended UseStratos Pro A4... OXY is a 4-wire device for dissolved oxygen and tem-perature measurement in biotechnology, pharmaceutical industry, as well as in the field of industry, environment, food processing and sew-age treatment. Optionally, it can be used for measuring oxygen traces.

Enclosure and mounting possibilities• The sturdy molded enclosure is rated IP 67/NEMA 4X for outdoor

use. It is made of glass-reinforced PBT / PC and measures 148 mm x 148 mm x 117 mm (H x W x D). It is provided with knockouts to allow:

• wall mounting (sealing plugs to seal the enclosure), see page 15

• post/pipe mounting (Ø 40 … 60 mm, 30 … 45 mm)see page 17

• panel mounting (138 mm x 138 mm cutout to DIN 43700), see page 18

Weather protector (accessory)The weather protector, which is available as accessory, provides additional protection against direct weather exposure and mechanical damage, see page 17.

Connection of sensors, cable glandsFor connecting the cables, the enclosure provides• 3 knockouts for cable glands M20x1.5• 2 knockouts for NPT 1/2” or rigid metallic conduitFor quasi-stationary installations with Memosens sensors, we recommend using the M12 device socket (accessory ZU 0822) instead of a cable gland – it allows simple replacement of the sensor cable without opening the device.

SensorsThe device has been designed for amperometric sensors, e.g. Knick SE 704 / SE 705 / SE 706 / SE 707 and for ISM sensors.(It can be easily retrofitted for Memosens sensors.)

8

DisplayPlain-text messages in a large, backlit LC display allow intuitive operation. You can specify which values are to be displayed in standard measuring mode (“Main Display”, see page 32).

Color-coded user interfaceThe colored display backlighting signals different operating states (e.g. alarm: red, HOLD mode: orange, see page 33).

Diagnostics functions“Sensocheck” and “Sensoface” monitor the sensor and provide clear information about its status, see page 119.

Data loggerThe internal logbook (TAN SW-A002) can handle up to 100 entries – up to 200 with AuditTrail (TAN SW-A003), see page 122.

2 parameter sets A/BThe device provides two parameter sets which can be switched manu-ally or via a control input for different process adaptations or different process conditions.For overview of parameter sets (table for copy), see page 50.

Password protectionPassword protection (passcodes) for granting access rights during operation can be configured, see page 128.

CorrectionHere, you can adapt the device to the process conditions by means of salinity and pressure correction, either manually or via an external current input (optional, released by TAN), see page 76.

Protective Wiring of Relay ContactsRelay contacts are subject to electrical erosion. Especially with inductive and capacitive loads, the service life of the contacts will be reduced. For suppression of sparks and arcing, components such as RC combinations, nonlinear resistors, series resistors and diodes should be used.

Typical AC applicationswith inductive load1) Load2) RC combination,

e.g. RIFA PMR 209 Typical RC combinations for 230 V AC: capacitor 0.1 µF / 630 V, resistor 100 Ω / 1 W

Information text appears on a green screen and the diagnostic menu appears on turquoise. The orange HOLD mode (e.g. during calibration) is quickly visible as is the magenta screen which indicates asset management messages for predictive diagnostics – such as maintenance request, pre-alarm and sensor wear.The alarm status has a particularly noticeable red display color and is also signaled by flashing display values. Invalid inputs or false pass-codes cause the entire display to blink red so that operating errors are noticeably reduced.

DiagnosticsDisplay of calibration data, display of sensor data, performing a device self-test, viewing the logbook entries, display of hardware/software ver-sions of the individual components. The logbook can store 100 events (00...99). They can be displayed directly on the device. The logbook can be extended to 200 entries using a TAN (Option).

HOLDManual activation of HOLD mode, e.g. for replacing a digital sensor. The signal outputs adopt a defined state.

CalibrationEvery sensor has typical characteristic values, which change in the course of the operating time. Calibration is required to supply a cor-rect measured value. The device checks which value the sensor delivers when measuring in a known solution. When there is a deviation, the device can be “adjusted“. In that case, the device displays the “actual“ value and internally corrects the measurement error of the sensor. Calibration must be repeated at regular intervals. The time between the calibration cycles depends on the load on the sensor. During calibration the device is in HOLD mode. During calibration the device remains in the HOLD mode until it is stopped by the operator.

ConfigurationThe analyzer must be configured for the respective measurement task. In the “Configuration“ mode you select the connected sensor, the measuring range to be transmitted, and the conditions for warning and alarm messages. During configuration the device is in HOLD mode. Configuration mode is automatically exited 20 minutes after the last keystroke. The device returns to measuring mode.

HOLD ModeThe HOLD mode is a safety state during configuration and calibration. Output current is frozen (LAST) or set to a fixed value (FIX). Alarm and limit contacts are disabled. The HOLD mode is indicated by orange display backlighting.

Terminating the HOLD mode The HOLD mode is ended by switching to measuring mode (hold meas key depressed). The display reads “Good Bye“, after that, the HOLD mode is exited. When the calibration mode is exited, a confirmation prompt ensures that the installation is ready for operation (e.g.: sensor reinstalled, located in process).

Alarm

Manual activation of HOLDThe HOLD mode can be activated manually from the HOLD menu. This allows checking or replacing a sensor, for example, without provoking unintended reactions at the outputs or contacts.Press meas key to return to selection menu.

AlarmWhen an error has occurred, Err xx is displayed immediately.Only after expiry of a user-defined delay time will the alarm be registered and entered in the logbook.During an alarm the display blinks, the display backlighting turns red.

Error messages can also be signaled by a 22 mA output current (see Configuration).The alarm contact is activated by alarm and power failure, see also “Configuration / Alarm Settings“.2 sec after the failure event is corrected, the alarm status will be deleted.

External activation of HOLD (SW-A005)The HOLD mode can be activated from outside by sending a signal to the HOLD input (e.g. from the process control system).

Time averaging filterTo smoothen the current output, a low-pass filter with adjustable filter time constant can be switched on. When there is a jump at the input (100 %), the output level is at 63 % after the time interval has been reached. The time interval can be set from 0 to 120 sec. If the time interval is set to 0 sec, the current output directly follows the input.Please note: The filter only acts on the current output, not on the display, the limit values, or the controller!During HOLD the filter is not applied.

Digital SensorsStratos Pro can be operated with digital sensors. Due to the galvanic isolation of Memosens sensors, earth or ground potentials have no effect here. Therefore, a Solution Ground or measures for equipotential bonding are not required. Digital sensors can be calibrated and maintained in the lab. This considerably simplifies on-site maintenance.

Memosens Sensors: Calibration and Maintenance in the LabThe “MemoSuite“ software allows calibrating Memosens sensors under reproducible conditions at a PC in the lab. The sensor param-eters are registered in a database. Documenting and archiving meet the demands of FDA CFR 21 Part 11. Detailed reports can be output as csv export for Excel.

CalibrationCalibration adapts the device to the individual sensor characteristics. It is always recommended to calibrate in air. Compared to water, air is a calibration medium which is easy to handle, stable, and thus safe. In the most cases, however, the sensor must be removed for a calibration in air.When dealing with biotechnological processes which require ster-ile conditions, the sensor cannot be removed for calibration. Here, calibration must be performed with aeration directly in the process medium (e.g. after sterilization).In the field of biotechnology, for example, often saturation is measured and calibration is performed in the medium for reasons of sterility. For other applications where concentration is measured (water control etc.), calibration in air has proved to be useful.

Please note:• All calibration procedures must be performed by trained person-

nel. Incorrectly set parameters may go unnoticed, but change the measuring properties.

• If a 2-point calibration is prescribed, the zero calibration should be performed prior to slope calibration.

Common combination: process variable / calibration mediumProcess variable Calibration Default

The calibration procedures for these two common applications are described on the following pages. Of course, other combinations of process variable and calibration medium are possible.

109

Selecting a Calibration ModeCalibration is used to adapt the device to the individual sensor characteristics, namely zero and slope. Access to calibration can be protected with a passcode (SERVICE menu).First, you open the calibration menu and select the calibration mode:

Calibration in air-saturated water / air (as configured)Zero calibrationProduct calibration (calibration with sampling)Temperature probe adjustment

110

Zero CalibrationThe sensor models SE 704, SE 705, SE 706, SE 707 and InPro6000 have very low zero currents. Therefore, a zero calibration is only recom-mended for measurement of oxygen traces. When a zero calibration is performed, the sensor should remain for at least 10 to 30 minutes in the calibration medium in order to obtain stable, non-drifting values. During zero calibration, a drift check is not performed. Zero current of a properly functioning sensor is notably less than 0.5 % of air current. The display (bottom: measured value, top: entered value) does not change until an input current is entered for the zero point. When measuring in an oxygen-free medium, the displayed current can be taken directly.

Product CalibrationCalibration with samplingDuring product calibration the sensor remains in the process. The measurement process is only interrupted briefly.

Procedure: During sampling the currently measured value is stored in the device. The device immediately returns to measuring mode.The cal mode indicator blinks and reminds you that calibration has not been termi-nated. The reference value is measured on the site, e.g. using a portable DO meter in a bypass.This value is then entered in the device. The new value for slope or zero is calculated from the stored value and the reference value. From the measured value, the device automatically recognizes whether a new slope or zero must be calculated (above approx. 5 % saturation: slope, below: zero).If the sample is invalid, you can take over the measured value saved during sam-pling instead of the reference value. In that case the old calibration values remain stored. Afterwards, you can start a new product calibration. The following describes a product calibration with slope correction – a product calibration with zero correc-tion is performed correspondingly.

After correct input of the ambulance TAN the device signals “PASS“ for 4 sec and resets the Service passcode to 5555.

Reset to factory settings:In the “SERVICE - DEFAULT“ menu you can reset the device to factory settings.Caution!After a reset to factory setting the device must be reconfigured completely, including the sensor parameters!

Option request:Communicate the serial number and hardware/soft-ware version of your device to the manufacturer. These data can be viewed in the Diagnostics/Version menu.The “transaction number“ (TAN) you will then receive is only valid for the device with the corresponding serial number.Releasing an option:Options come with a “transaction number“ (TAN). To release the option, enter this TAN and confirm by pressing enter .

Sensor: Resetting the wear counterWhen you have replaced the electrolyte or the membrane of the OXY sensor, you should reset the wear counter.Default setting is “NO”. Select “YES” and press enter to reset the wear counter.

Sensoface(Sensocheck must have been activated during configuration.)

The smiley in the display (Sensoface) alerts to sensor problems (defective sensor, sensor wear, defective cable, maintenance request). The permitted calibration ranges and the conditions for a friendly, neutral, or sad Sensoface are summarized in the following table. Additional icons refer to the error cause.

SensocheckContinuously monitors the sensor and its wiring. Critical values make the Sensoface “sad” and the corresponding icon blinks:

The Sensocheck message is also output as error message Err 15. The alarm contact (A4... only) is active, the display backlighting turns red, output current 1 is set to 22 mA (when configured correspondingly). Sensocheck can be switched off during configuration (then Sensoface is also disabled). Exception: After a calibration a smiley is always displayed for confirmation.

Please note:The worsening of a Sensoface criterion leads to the devaluation of the Sensoface indicator (Smiley becomes “sad”). An improvement of the Sensoface indicator can only take place after calibration or removal of the sensor defect.

146

Sensoface

Display Problem StatusZero and slope

Zero and slope of the sensor are still okay.The sensor should be replaced soon.

Zero and/or slope of the sensor have reached values which no longer ensure prop-er calibration. Replace sensor.

Calibration timer

Over 80 % of the calibration interval has already past.

The calibration interval has been exceeded.

Sensor defect Check the sensor and its con-nections (see also Err 15, Error Messages).

Response time

Sensor response time has increased.The sensor should be replaced soon.To achieve an improvement, clean the sensor and check the electrolyte and membrane.

Sensor response time has sig-nificantly increased ( > 600 s, calibration aborted after 720 s)Check electrolyte and mem-brane, replace sensor if required.

147

Sensoface

Display Problem StatusSensor wear (for digital sensors only)

Wear is over 80%. Check electrolyte and membrane.

Wear is at 100%.Check electrolyte and mem-brane, replace if required.Please note: Reset the wear counter in the SERVICE - SENSOR menu when you have replaced the membrane or electrolyte.

FDA 21 CFR Part 11Conformity with FDA 21 CFR Part 11In their directive “Title 21 Code of Federal Regulations, 21 CFR Part 11, Electronic Records; Electronic Signatures“ the US American health agency FDA (Food and Drug Administration) regulates the production and processing of electronic documents for pharmaceutical devel-opment and production. This results in requirements for measuring devices used for corresponding applications. The following features ensure that the measuring devices of this Series meet the demands of FDA 21 CFR Part 11:

Electronic Signature – PasscodesAccess to the device functions is regulated and limited by individually adjustable codes – “Passcodes“ (see SERVICE). This prevents unauthor-ized modification of device settings or manipulation of the measure-ment results. Appropriate use of these passcodes makes them suitable as electronic signature.

Audit TrailEvery (manual) change of device settings can be automatically docu-mented. Each change is tagged with a “Configuration Change Flag“, which can be interrogated and documented using HART communica-tion. Altered device settings or parameters can also be retrieved and documented using HART communication.

Extended logbookAudit Trail also records function activations (CAL, CONFIG, SERVICE), some Sensoface messages (cal timer, wear), and opening of the enclosure.
