IntroductionIntended UseStratos Pro A4... MSPH/MSPH is a two-channel process unit for pH measurement using 2 Memosens pH sensors. The two measured values can be used for various differential calculations (pH, mV, temperature).The sturdy molded enclosure can be fixed into a control panel or mounted on a wall or at a post. The protective hood, which is avail-able as accessory, provides additional protection against direct weather exposure and mechanical damage.

Plain-text messages in a large, backlit display allow intuitive operation. The colored display backlighting signals alarm messages (red) or HOLD mode (orange).The “Sensocheck“ automatic monitoring of sensor and cables and the “Sensoface“ function for clear indication of the sensor condition provide excellent diagnostics. The internal logbook (TAN SW-A002) can handle up to 100 entries – up to 200 with AuditTrail (TAN SW-A003). Password protection for granting access rights during operation can be configured. The floating, digital control input “HOLD“ allows remote controlled switching to HOLD mode.The “CONTROL“ input allows evaluation of external monitoring equip-ment, such as a flow monitoring system.For that purpose, you can also monitor the current input (optional) for keeping a desired value.The device provides two current outputs (for transmission of mea-sured value and temperature, for example) and four floating relay contacts. Current is provided through a universal power supply 24 ... 230 V AC/DC, AC: 45 ... 65 Hz.

DiagnosticsDisplay of calibration data, display of sensor data, performing a device self-test, viewing the logbook entries, display of hardware/software versions 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 de-vice 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.

ServiceMaintenance functions (current source, relay test, controller test), IrDA operation, passcode assignment, reset to factory settings, enabling of options (TAN).

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 inactive. 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).

Output signal during HOLD:

Output signal response• Last: The output current is frozen at its last value. Recommended

for short configuration procedures. The process should not change decisively during configuration. Changes are not noticed with this setting!

• Fix: The output current is set to a value that is noticeably different from the process value to signal the control system that the device is being worked at.

27

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 of 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).

CalibrationPlease note:• All calibration procedures must be performed by trained personnel.

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

• The response time of the sensor and temperature probe is considerably reduced when the sensor is first moved about in the buffer solution and then held still.

• The device can only operate properly when the buffer solutions used correspond to the configured set. Other buffer solutions, even those with the same nominal values, may demonstrate a different temperature response. This leads to measurement errors.

When using an ISFET Memosens sensor, the nominal zero point must be adjusted each time a new sensor is connected. This is important if you want to obtain reliable Sensoface messages. The Sensoface messages issued during all further calibrations are based on this basic calibration.

81

Calibration is used to adapt the device to the individual sensor characteristics, namely asymmetry potential and slope. Access to calibration can be protected with a passcode (SERVICE menu). First, open the calibration menu and select the sensor (SENSOR_A / SENSOR_B) and then the calibration mode:

SENSOR_A Calibrating sensor ACAL_PH Adjusting the pHP_CAL Product calibration

(calibration with sampling)ISFET-ZERO ISFET operating point

(displayed only when ISFET Memosens sensor is connected)

Zero Adjustment (ISFET)This adjustment allows the use of ISFET Memosens sensors. The func-tion is available when an ISFET Memosens sensor is connected. The adjustment is made using a zero buffer (pH 7.00). Permitted range for buffer value: pH 6.5 ... 7.5 Temperature-corrected input. Maximum zero offset: ±750 mV

Immerse sensor in a pH 7.00 buffer. Enter the temperature-corrected pH value in the range 6.50 to 7.50 using the arrow keys (see buffer table).Press enter to confirm.

If the zero offset of the sensor is too large (> ± 750 mV), a CAL ERR error mes-sage is generated. In that case the sensor cannot be calibrated. At 500 mV Sensoface becomes sad.

Please note: Stability check can be stopped (by pressing enter). However, this re-duces calibration accuracy.

Adjustment (Calimatic)

Automatic Calibration (Calimatic)The AUTO calibration mode must have been preset during configura-tion. Make sure that the buffer solutions used correspond to the con-figured buffer set. Other buffer solutions, even those with the same nominal values, may demonstrate a different temperature response. This leads to measurement errors.

Product calibration

Product Calibration (pH)Calibration by sampling (one-point calibration). During product calibration the sensor remains in the process. The measurement process is only interrupted briefly.Procedure: 1) The sample is measured in the lab or directly on the site using a

portable meter. To ensure an exact calibration, the sample tempera-ture must correspond to the measured process temperature. During sampling the device saves the currently measured value and then returns to measuring mode. The “calibration“ mode indicator blinks.

2) In the second step you enter the measured sample value in the device. From the difference between the stored measured value and entered sample value, the device calculates the new asymmetry potential.

If the sample is invalid, you can take over the value stored during sampling. In that case the old calibration values are stored. Afterwards, you can start a new product calibration.

Display Action RemarkSelect product calibration: P_CAL.Press enter to proceed.

Ready for calibration. Hourglass blinks.

Sensoface(Sensocheck must have been activated during configuration.)

The smiley in the display (Sensoface) alerts to sensor problems (defec-tive 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 (glass electrode). The alarm contact is active, the display backlighting turns red, output current 1 is set to 22 mA (when configured correspond-ingly). 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.

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.
