Autoclaving Counter

After reaching a specied limit value the autoclaving counter generates a Sensoface message. As soon as the counter has reached the specied value, Sensoface is getting “sad”. Pressing the info key shows the text “AUTOCLAVE CYCLES OVERRUN” which reminds you that the maximum number of autoclaving cycles has been reached. After each autoclaving process, you must manually increment the autoclaving counter in the SENSOR service menu on the transmitter. The transmitter displays “INCREMENT AUTOCLAVE CYCLE” as conrmation. You can congure the current outputs so that a Sensoface message generates a 22-mA error signal, see page 63.

Introduction

Intended Use

Stratos Pro A401B PH is used for pH/mV, ORP and temperature measurement in industry, environment, food processing and sewage treatment.

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 (with sealing plugs to seal the enclosure), see page 16

• 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 glands

For connecting the cables, the enclosure provides

• 3 knockouts for cable glands M20x1.5

• 2 knockouts for NPT 1/2” or rigid metallic conduit

For 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.

Sensors

The device has been designed for application with commercially available sensors with a nominal zero point at pH 7, ISFET sensors or digital sensors. (It can be easily retrotted for Memosens sensors.)

Introduction

Display

Plain-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 38).

Color-coded user interface

The colored display backlighting signals dierent operating states (e.g. alarm: red, HOLD mode: orange, see page 39).

Diagnostics functions

“Sensocheck“ automatically monitors the glass and reference electrodes; and the “Sensoface“ function clearly indicates the sensor condition, see page 137.

Data logger

The internal logbook (TAN SW-A002) can handle up to 100 entries – up to 200 with AuditTrail (TAN SW-A003), see page 140.

2 parameter sets A, B

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. For overview of parameter sets (table for copy), see page 56.

Password protection

Password protection (passcodes) for granting access rights during operation can be congured, see page 146.

Automatic calibration with Calimatic

You can choose from the most commonly used buer solutions, see page 158. An individual buer set can also be entered, see page 168.

Protective Wiring of Relay Contacts

Relay 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 applications with inductive load

1) Load

2) 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

3) Contact

WARNING!

Make sure that the maximum ratings of the relay contacts are not exceeded even during switching!

Color-Coded User Interface

The color-coded user interface guarantees increased operating safety. Operating modes are clearly signaled. The normal measuring mode is white. 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 ashing display values. Invalid inputs or false passcodes cause the entire display to blink red so that operating errors are noticeably reduced.

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 replacing a digital sensor. The signal outputs adopt a dened state.

Calibration

Every sensor has typical characteristic values, which change in the course of the operating time. 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. 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.

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

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

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). The alarm contact is activated by alarm and power failure, see also “Conguration / Alarm Settings“. 2 sec after the failure event is corrected, the alarm status will be deleted.

Support of Pfaudler Sensors

or pH sensors with a zero point other than pH 7 and/or deviating slope, e.g. pH sensors with a zero point at pH 4.6

This requires an additional function (TAN). The option is enabled in the SERVICE / OPT: PFAUDLER menu (see page 148).

For Pfaudler standard pH sensors, you can specify a nominal zero point and a nominal slope. In addition, you can enter a pHiso value. The additional entries appear in the CONFIGURATION / SENSOR menu:

SNS: NOM ZERO (default: 07.00 pH) SNS: NOM SLOPE (default: 59.2 mV) SNS: PH_ISO (default: 07.00 pH)

Prior to measurement, you must enter the values for nominal zero and slope and the isothermal intersection point pHiso as provided by the manufacturer and perform a calibration using suitable buffer solutions. When you use a Memosens Pfaudler sensor, the data will be read from the sensor or will be set to standard values. Here, you do not have to make entries. The respective menu items will be suppressed. The nominal ZERO/SLOPE values are required for the proper functioning of the sensor monitoring and calibration functions (Sensoface, Calimatic), they do not replace an adjustment (calibration)!

Autoclaving Counter

After reaching a specied limit value the autoclaving counter generates a Sensoface message. As soon as the counter has reached the specied value, Sensoface is getting “sad”. Pressing the info key shows the text “AUTOCLAVE CYCLES OVERRUN” which reminds you that the maximum number of autoclaving cycles has been reached. After each autoclaving process, you must manually increment the autoclaving counter in the SENSOR service menu on the transmitter. The transmitter displays “INCREMENT AUTOCLAVE CYCLE” as conrmation. You can congure the current outputs so that a Sensoface message generates a 22-mA error signal, see page 81.

Time averaging lter

To smoothen the current output, a low-pass lter with adjustable lter 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 lter only acts on the current output, not on the display, the limit values, or the controller! During HOLD the lter is not applied. This prevents a jump at the output.
