Introduction

Intended Use

Stratos Pro A2... COND is used for measurement of electrical conductivity and temperature in liquids. Fields of application are: biotechnology, chemical industry, environment, food processing, water/waste-water treatment. The sturdy molded enclosure can be  xed into a control panel or mounted on a wall or at a post. The protective hood, which is available as accessory, provides additional protection against direct weather exposure and mechanical damage. The device has been designed for 2- and 4-electrode sensors, particularly for Models SE 600, SE 603, SE 604, SE 610, SE 620, SE 630 and for Memosens sensors. 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). The device provides two parameter sets which can be switched manually or via a control input for di erent process adaptations or di erent process conditions (e.g. beer and CIP). Password protection for granting access rights during operation can be con gured. Two  oating, digital control inputs (“Hold“ and “Control“) are available for external control. The device provides two current outputs (for transmission of measured value and temperature, for example).

Approvals for Measurement in Hazardous Locations:

Stratos Pro A201/A211N COND: General Safety.

Stratos Pro A201/A211X COND: Approved for operation in

hazardous locations according to IECEx / ATEX / FM / CSA.

Operating Modes

Diagnostics

Display 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).

HOLD

Manual activation of HOLD mode, e.g. for servicing. The signal outputs adopt a de ned state.

Calibration

Every sensor has typical characteristic values. Calibration is required to supply a correct 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. During calibration the device is in HOLD mode.

During calibration the analyzer remains in the HOLD mode until it is stopped by the operator.

Con guration

The analyzer must be con gured for the respective measurement task. In the “Con guration“ mode you select the connected sensor, the measuring range to be transmitted, and the conditions for warning and alarm messages. During con guration the device is in HOLD mode.

Con guration mode is automatically exited 20 minutes after the last keystroke. The device returns to measuring mode.

HOLD Mode

The HOLD mode is a safety state during con guration and calibration. Output current is frozen (Last) or set to a  xed value (Fix). The HOLD mode is indicated by orange display backlighting.

HOLD mode, display icon:

Output Signal Response

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

for short con guration procedures. The process should not change

decisively during con guration. Changes are not noticed with this

setting!

Fix:• The output current is set to a value that is noticeably di erent

from the process value to signal the control system that the device

is being worked at.

Output Signal During HOLD:

Output current [mA]

Output signal for HOLD FIX setting = 21.0 mA

Output signal for HOLD LAST setting

HOLD active

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 con rmation prompt ensures that the installation is ready for operation (e.g.: sensor reinstalled, located in process).

Alarm

External Activation of HOLD

The HOLD mode can be activated from outside by sending a signal to

the Hold input (e.g. from the process control system).

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.

Alarm

When an error has occurred, Err xx is displayed immediately.

Only after expiry of a user-de ned 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 Con guration).

Calibration

Please note:

All calibration procedures must be performed by trained person-• nel. Incorrectly set parameters may go unnoticed, but change the measuring properties.

Calibration can be performed by:

Determining the cell constant with a known calibration solution• Input of cell constant (e.g. for ultrapure-water sensors)• Sampling (product calibration)• Temperature probe adjustment•

Selecting a Calibration Mode

Calibration adapts the device to the individual sensor characteristics. Access to calibration can be protected with a passcode (SERVICE menu). First, you open the calibration menu and select the calibration mode:

Product Calibration

Calibration by sampling – for product calibration, the uncompensated conductivity (μS/cm, mS/cm, S/m) is used. During product calibration the sensor remains in the process. The measurement process is only interrupted brie y.

Procedure:

The sample is measured in the lab or directly on the site using a por-1) table meter. To ensure an exact calibration, the sample temperature should correspond to the measured process temperature. During sampling the device saves the currently measured value and then returns to measuring mode. Then, the “calibration“ mode indicator blinks. In the second step you enter the measured sample value in the 2) device. From the di erence between the stored measured value and

entered sample value, the device calculates the new cell constant. 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 Remark

When IrDA communication is active, the device remains in the HOLD mode for reasons of safety. Further operation is performed via IrDA.

End communication by pressing meas.

Exception: Firmware update (must not be interrupted!)

Service

Menu item Remark

Assigning passcodes:

In the “SERVICE - CODES“ menu you can assign passcodes to DIAG, HOLD, CAL, CONF, and SERVICE modes (Service preset to 5555). When you have lost the Service passcode, you have to request an “ Ambulance TAN“ from the manufacturer specifying the serial number of your device. To enter the “Ambulance TAN“, call the Service function and enter passcode 7321. 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/ software 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.

Release of options:

Options come with a “transaction number“ ( TAN). This TAN must be entered and confirmed using enter to release the option.

USP Function

According to the "USP" directive (U.S.Pharmacopeia), Section 645 "Water Conductivity" the conductivity of pharmaceutical waters can be monitored online. To do so, the conductivity is measured without temperature compensation and is compared with limit values (see table on next page). The water is usable when the conductivity is below the USP limit. If the conductivity values are higher, further test steps must be performed according to the directive. To increase safety, the USP limit value can be reduced in the device. To do so, a factor (%) is speci ed.

Con guring:

SNS• menu group:

When “USP function“ has been selected, the measuring range

is  xed to 00.00.....99.99 μS/cm. Temperature compensation is

switched o . Temperature is monitored.

If the USP limit is exceeded, a 22 mA signal is output.
