Operation in Explosive Atmospheres: PH 3400X-035 Module
The module is approved for operation in explosive atmospheres.
When installing the product in a hazardous location, observe the information in
the supplements to the certificates and, if applicable, the relevant control draw-
ings.
Observe all applicable local and national codes and standards for the instal-
lation of electrical equipment in explosive atmospheres. For orientation,
please refer to IEC 60079-14, EU directives 2014/34/EU and 1999/92/EC (ATEX),
NFPA70 (NEC), ANSI/ISA-RP12.06.01.
WARNING! Possible impairment of explosion protection.
• Modules which have already been used shall be subjected to a professional
routine test before they may be operated in another type of protection.
• Prior to commissioning, the operating company must verify the intrinsic
safety in accordance with the installation regulations of IEC60079-14 for
the complete interconnection of all equipment involved, including the
connecting cables.
• The interconnection of Ex and non-Ex modules (mixed assembly) is not
permitted.
• In hazardous locations the device shall only be cleaned with a damp cloth to
prevent electrostatic charging.
Maintenance
The Protos modules cannot be repaired by the user. For inquiries regarding

ISM - Intelligent Sensor Management
The module allows the connection of ISM sensors 1).
ISM is an open system that is compatible to existing connection systems (VP 8)
and permits the use of conventional sensors. The system is not restricted to pH
measurement. Sensors from different manufacturers can be connected.
During pH measurement it is still possible to continuously monitor the glass
and reference electrode.
ISM sensors have an “electronic datasheet” which allows the storage of addi-
tional operating parameters such as calibration date and settings directly in the
sensor.
An ISM sensor is immediately identified due to the “Plug & Measure” concept.
This ensures the clear assignment of a sensor to a measuring point. The risk of
confusing the sensors is eliminated. The sensors can be precalibrated in the lab.
On-site calibration/adjustment is no more required.
Information available in the ISM sensor
Each sensor is clearly identified by the unalterable factory data (manufacturer,
sensor description).
Data for predictive maintenance can be transferred from the meter to the sen-
sor (for example the maximally permitted number of CIP/SIP cycles).
Statistical data inform on the product life cycle of the sensor: data of the last
3 calibrations, cal record, buffer values, voltages, temperature, response time,
glass and reference impedance.
This allows a comprehensive diagnostic:
- Wear indication
- Adaptive calibration timer
Taking over the minimum/maximum temperature
The maximum temperature range is stored in the ISM sensor.
When "Sensor monitoring Auto" has been selected, the value pair for the
maximum + minimum temperature is automatically taken over from the sensor.

These are, for example, the measurement range,
zero and slope of the sensor, but also the type
of temperature probe. Without any further
parameter setting, measurement starts at once,
the measuring temperature is simultaneously
detected.
With “Plug&Measure”, premeasured ISM sensors
can immediately be used for measurement
without previous calibration.

Sensor monitoring details
When an ISM sensor is connected, the values for
slope, zero, reference and glass impedance (pH
electrodes), response time, and max./min. tem-
peratures are automatically read by the module.
Individual specifications are not overwritten
by the ISM data. Additional specifications are
required for sensor wear, CIP/SIP counter, auto-
claving counter, and sensor operating time. The
tolerance limits are displayed in gray.
Configuring an ISM sensor is considerably
safer and easier than configuring a conven-
tional sensor. Since ISM sensors have an “elec-
tronic datasheet”, many parameters are already
provided by the sensor and automatically taken
over by the analyzer.

When setting the sensor data, the maximum

predictive maintenance.

Temp Probe Adjustment
This function is used for compensating for the
individual tolerance of the temperature probe
and the influence of the lead resistances.
Adjustment may only be carried out after the
process temperature is precisely measured
using a calibrated reference thermometer.
The measurement error of the reference
thermometer should be less than 0.1 °C.
Adjustment without precise measurement
might result in considerable deviations of the
measured value display!

CIP/SIP Cycles
CIP (Cleaning in Place) / SIP (Sterilization in Place)
CIP/SIP cycles are used for cleaning or sterilizing the process-wetted parts
in the process. They are performed for biotech applications, for example.
Depending on the application, one (alkaline solution, water) or more chemicals
(alkaline solution, water, acidic solution, water) are used.
The temperatures for CIP are around 80 °C/176 °F, for SIP around 110°C/230°F.
These procedures extremely stress the sensors.
ISM sensors can release a message when a preset number of CIP/SIP cycles is
exceeded. This allows replacing the sensor in time.

Example of CIP cycle:
The device automatically recognizes the CIP and SIP cycles and corresponding-
ly increments the counter. The user can specify the max. number of cycles and
decide whether a message is to be generated when this number is exceeded.
These data are not overwritten even after sensor replacement.
The number of CIP cycles is shown in the sensor wear monitor of the
Diagnostics menu when an individual max value has been specified.
Default values for the counters
(for evaluating the sensor wear):
CIP = 0
SIP = 300
Autoclaving counter = 500 hours for one cycle
Note:
The counters are incremented no earlier than
2hours after start of the cycle, even if the cycle
itself has already been terminated.
Note: The display may vary depending on the device version.

Attaching the terminal plates
The terminal plates of the lower modules can be

This facilitates maintenance and service.

17
Installing the Module
CAUTION! Electrostatic discharge (ESD).
The modules' signal inputs are sensitive to electrostatic discharge.
Take measures to protect against ESD before inserting the module and wiring
the inputs.
Note: Strip the insulation from the wires using a suitable tool to prevent dam-
age.
1) Switch off the power supply to the device.
2) Open the device (loosen the 4 screws on the front).
3) Plug the module into the slot (D-SUB connector),
see figure.
4) Tighten the module's fastening screws.
5) Open the ESD shield (covering terminals 2 and 8).
6) Connect the sensor and separate temperature probe if necessary, see
"Wiring Examples".
Note: To avoid interferences, the cable shielding must be completely
covered by the ESD shield.
7) Fit the ESD shield back into place (covering terminals 2 and 8).
8) Check whether all connections are correctly wired.
9) Close the device by tightening the screws on the front.
10) Switch on the power supply.
CAUTION! Incorrect measurement results.
Incorrect parameter setting, calibration or adjustment may result in incorrect
measurements being recorded. Protos must therefore be commissioned by a
system specialist, all its parameters must be set, and it must be fully adjusted.
