Safety functions

Hold modeDisplay:

The Hold mode is a safety state during configuration and cali-bration. Output current is frozen (Last) or set to a fixed value(Fix). Alarm and limit contacts are disabled. If the calibration or configuration mode is exited, the Stratosremains in the Hold mode for safety reasons. This preventsundesirable reactions of the connected peripherals due toincorrect configuration or calibration. The measured value and“HOLD” are displayed alternately. The Stratos only returns tomeasuring mode after enter is pressed and a waiting time of20 s has passed.

29

To activate the Hold mode from outside

The Hold mode can be activated from outside by sending asignal to the Hold input (e.g. from the process control system).

Concentration measurementFor the solutions listed above, the Stratos can determine the substanceconcentration from the measured conductivity and temperature valuesin % by wt. The measurement error is made up of the sum of measure-ments errors during conductivity and temperature measurement andthe accuracy of the concentration curves stored in the Stratos (seePg 114). We recommend to calibrate the Stratos together with the sensor. Forexact temperature measurement, you should perform a temperatureprobe adjustment. For measuring processes with rapid temperaturechanges, a separate temperature probe with fast response should beused. When measuring processes such as dilution or intensification ofCIP solutions (Clean-In-Place), it is helpful to switch between theparameter sets for measuring the process medium and for measuringthe CIP solution.

Information on calibrationCalibration adapts the meter to the conductivity sensor.Calibration can be performed by:• Input of cell constant (e.g. for ultrapure-water sensors) • Determining the cell constant with a known

calibration solution• Sampling (product calibration)• Temperature probe adjustment

Note:• All calibration procedures must be performed by trained

personnel. • Incorrectly set parameters may go unnoticed, but change the

measuring properties.

For product calibration the measured variable is used as configured:Conductivity (µS/cm, mS/cm, S/m), resistivity (MΩ·cm). During productcalibration the sensor remains in the process. The measurement is onlyinterrupted briefly.Calibration is without TC correction.

Procedure: During sampling the currently measured value is stored inthe Stratos. The Stratos immediately returns to measuring mode. Thecalibration mode indicator flashes and reminds you that calibration hasnot been terminated. The sample is measured in the lab or directly on the site using aportable meter. The lab value is then entered in the Stratos. The newcell constant is calculated from these two values.If the sample is invalid, you can take over the value stored during sam-pling. In that case the old calibration values are stored. Afterwards,you can start a new product calibration.

Controller functions

Pulse length / pulse frequency controller

Pulse length controller (PLC)The pulse length controller is used to operate a valve as anactuator. It switches the contact on for a time that depends onthe controller output. The period is constant. A minimum ONtime of 0.5 sec is maintained even if the controller output takescorresponding values.

SensocheckContinuously monitors the sensor and its wiring. Sensocheck can be switched off.Critical values make the Sensoface “sad” and the corresponding icon flashes:

The Sensocheck message is also output as error message Err33. The alarm contact is active, the red LED is lighted, outputcurrent 1 is set to 22 mA (when configured correspondingly).Sensocheck can be switched off during configuration (thenSensoface is also disabled). Exception: After a calibration aSmiley is always displayed for confirmation.

Sensoface

The little smiley in the display (Sensoface) provides informationabout the sensor condition (defects, maintenance required,cable capacitance too high). It alerts to significant sensor polarization or excessive cablecapacitance e.g. caused by an unsuitable cable or a cable thatis too long. The permitted calibration ranges and the condi-tions for a friendly, neutral, or sad Sensoface are summarized inthe following chart. Additional icons refer to the error cause.

NoteThe worsening of a Sensoface criterion leads to the devaluationof the Sensoface indicator (Smiley becomes “sad”). To reset theSensoface indicator, the defect must be remedied and theStratos be calibrated.

Note:When very fast response times (t90) are required, e.g. whendetecting separation layers, Sensocheck should be switched off(see “Specifications” Pg 100).


According to the “USP” directive (U.S. Pharmacopeia), Section 645“Water Conductivity”, the conductivity of pharmaceutical waters canbe monitored online. To do so, the conductivity is measured withouttemperature compensation and is compared with limit values (see“Temperature/conductivity table as per USP” on Pg 97).The water is usable if the conductivity is below the USP limit. For higher conductivities, further test steps must be performed accordingto the directive.To increase safety the USP limit value can be reduced in the Stratos. To do so, a factor (%) is entered.

Configuration steps• out1 menu group:

When USP function has been selected, the measurement range isfixed to 00.00 ... 9.99 µS/cm. Temperature compensation is switchedoff. Temperature is monitored (see Pg 37).

• In the rL. menu group select USP as limit function. Relays 1 and 2 can now be used as USP limit contacts (see Pg 58).

• Reduced limit contact U1 (Relay 1): Enter USP factor (reduced limit, configurable in the range 10 % ... 100 %). Set contact response for relay 1.Set delay time (see Pg 65).

Glossary

Conductivity Conductivity χ [S/cm] = G [S] · c [1/cm]

Conductivitysensor

Either 2- or 4-electrode sensors can be con-nected. The cell constant of the sensor inuse must be entered or be determined usinga calibration solution taking account of thetemperature. A special device variant (Stratos e 2402CondI) is provided for electrodeless sensors.

Conductance G [S] =1 / R [Ω]Conductance

Temperaturecoefficient

With temperature compensation activated,the measured value is calculated to the valueat the reference temperature (25 °C) usingthe temperature coefficient.

Temperaturecompensation

Calculates the measured conductivity valuefor a reference temperature.
