Safety Instructions
Operation in Explosive Atmospheres: COND 3400X-041 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
drawings.
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
module repair, please contact Knick Elektronische Messgeräte GmbH & Co. KG
at www.knick.de.

Attaching the Terminal Plates
The terminal plates of the lower modules can
be sticked to the inner side of the door. This
facilitates maintenance and service.

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) Connect the sensor and separate temperature probe if necessary, see
"Wiring Examples".
6) Check whether all connections are correctly wired.
7) Close the device by tightening the screws on the front.
8) 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.

• Calibration: Detecting deviations without readjustment
• Adjustment: Detecting deviations with readjustment
Calibration / Adjustment
Note: Function check (HOLD) active for the currently calibrated module
Current outputs and relay contacts behave as configured
NOTICE!
Without adjustment every conductivity meter delivers an imprecise or wrong
output value! Every conductivity sensor has its individual cell constant.
To determine the correct conductivity value, the conductivity meter must be
adjusted to the sensor. From the sensor signal and the cell constant, the meter
calculates the conductivity value to be displayed.
Procedure
Every conductivity sensor has its individual cell constant.
Depending on the sensor design, the cell constant may vary over a wide range.
As the conductivity is calculated from the measured conductance and the cell
constant, this must be known to the measuring system. For calibration or sen-
sor standardization, either the known (stamped on) cell constant of the con-
ductivity sensor used is entered in the measuring system or it is determined
automatically by measuring a calibration solution with a known conductivity.
The data are stored in a calibration record. By “Adjustment” the determined
calibration data can be used for correction (see following page).
• Use fresh calibration solutions only!
• The calibration solution used must have been selected during parameter
setting.
• Calibration accuracy decisively depends on the exact detection of the cali-
bration solution’s temperature. Using the measured or entered temperature,
the Protos determines the nominal value for the calibration solution from a
stored table.
• Observe response time of temperature probe!
• For exact determination of the cell constant, wait until the temperature
probe and calibration solution have the same temperature.

20
Calibration / Adjustment
Adjustment
means that the cell constant determined by a calibration is taken over.
It is entered in the calibration record. (Cal record can be called up in the
Diagnostics menu for the COND 3400(X)-041 module.) The value is only
effective for calculating the measured variables when the calibration has been
terminated with an adjustment.
A passcode ensures that an adjustment can only be performed by an autho-
rized person (Administrator). The Operator can check the current sensor data by
a calibration and inform the Administrator when there are deviations. You can
use the add-on function SW3400-107 / FW4400-1071) for granting access rights
(passcodes) and for AuditTrail (continuous data recording and backup accor-
ding to FDA 21 CFR Part 11).
Operator (without administrator rights)
After calibration, change to measuring
mode. Inform Administrator.
When opening the menu (Calibration,
respective module), the Administrator
sees all data of the last calibration and
can take over the values or perform a
new calibration.
