1 Safety
This document contains important instructions for the use of the product. Always follow all
instructions and operate the product with caution. If you have any questions, please contact Knick
Elektronische Messgeräte GmbH & Co. KG (sometimes hereafter referred to as "Knick") using the
information provided on the back page of this document.
1.1 Intended Use
Stratos Multi E461N is an industrial transmitter for PROFINET communication. It features an RJ45
socket and can therefore be connected in a star topology. With the use of a Y cable, it can be
connected in a ring topology. In the field of liquid analysis, the device can measure pH values, ORP,
conductivity (contacting or inductive), and oxygen content, both dissolved and in the gaseous phase.
Alongside a permanently installed measuring channel I for Memosens sensors, the modular transmit-
ter has a slot that can be equipped with analog or digital measuring modules (measuring channel II).
The transmitter can be extended with device-specific add-on functions called TAN options.
The defined rated operating conditions must be observed when using this product. These conditions
are set out in full in the Specifications chapter of the user manual, as well as, in parts, of the installation
guide.
USE CAUTION AT ALL TIMES WHEN INSTALLING, USING, MAINTAINING OR OTHERWISE INTERACTING WITH
THE PRODUCT. ANY USE OF THE PRODUCT EXCEPT AS SET FORTH HEREIN IS PROHIBITED, AND MAY RESULT
IN SERIOUS INJURY OR DEATH, AS WELL AS DAMAGE TO PROPERTY. CUSTOMER SHALL BE SOLELY RESPON-
SIBLE FOR ANY DAMAGES RESULTING FROM OR ARISING OUT OF AN UNINTENDED USE OF THE PRODUCT.
Inputs and Outputs (SELV, PELV)
All inputs and outputs must be connected to SELV/PELV circuits.
1.2 Symbols and Markings on the Product
CE marking
Special conditions and danger points! Observe the safety information and instructions on safe use of the
product as outlined in the product documentation.
Reminder to read the documentation.
Protection class II
1.3 Personnel Requirements
Customer shall ensure that any personnel using or otherwise interacting with the product is
adequately trained and has been properly instructed.
The operating company shall comply and cause its personnel to comply with all applicable laws, regu-
lations, codes, ordinances and relevant industry qualification standards related to product. Failure to
comply with the foregoing shall constitute a violation of operating company’s obligations concerning
the product, including but not limited to an unintended use as described in this document.
1.4 Safety Training
Upon request, Knick Elektronische Messgeräte GmbH & Co. KG will provide safety briefings and
product training during initial commissioning of the product. More information is available from the
relevant local contacts.

1.5 Installation and Commissioning
Adhere to all applicable local and national codes and standards for the installation of electrical equip-
ment. Information on installation is provided in the installation guide for the Stratos Multi.
Comply with the points below during installation and commissioning:
• The device must be installed in a stationary location by a licensed electrician in compliance with all
applicable local and national codes and standards.
• Take care to avoid notches when stripping the wires.
• The device must be commissioned by a system specialist, and it must be fully configured.
Cables
Only use cables with a suitable temperature resistance.
Transmitter Cable temperature resistance
Stratos Multi 75°C / 167°F or higher
In the event of direct connection to the RJ45 socket without the ZU1139 Y cable or ZU1073 adapter
cable, a suitable PROFINET cable must be used. In this case, PN port 2 (PHY1) is used.
Mains Connection
The device does not have a power switch. An appropriately arranged and accessible disconnecting
device for the transmitter must be present in the system installation. The disconnecting device must
disconnect all non-grounded, current-carrying wires. The disconnecting device must be labeled in a
way that enables the associated transmitter to be identified. The power line may carry dangerous
touch voltages. Touch protection must be ensured by proper installation.
Parameter Setting and Adjustment
Incorrect parameter settings or adjustments can result in incorrect outputs. For this reason, Stratos
Multi must be commissioned by a specialist, who will also set the parameters and make adjustments.
Relay Contacts
Make sure that the maximum ratings of the relay contacts are not exceeded even during switching.
The relay contacts are subject to electrical erosion, which reduces their service life under inductive and
capacitive loads.
Degree of Protection
The housing of the device is dust-tight and offers complete protection against contact as well as
protection against strong water jets.
• Europe: IP protection IP66/IP67
• USA: TYPE4X Outdoor (with pressure compensation)
Memory Card
When opening the device, there may be dangerous touch voltages in the terminal compartment.
Professional installation guarantees direct contact protection.
The memory card can be replaced during operation. When doing so, maintain sufficient distance from
the mains connection cables and do not use tools.

1.6 Maintenance
Stratos Multi does not require maintenance.
If maintenance is required at the measuring point (e.g., sensor replacement), function check mode
(HOLD) must be activated as follows on the device:
• Open Calibration (the selected channel only)
• Open Maintenance (current source, measuring points)
• Open Parameter Setting at the operator and administrator levels
1.7 Disposal
The local codes and regulations must be observed when disposing of the product.
1.8 Residual Risks
The product has been developed and manufactured in accordance with generally accepted safety
rules and regulations. The following residual risks remain:
• Ambient conditions with chemically corrosive substances may prevent the system from working
properly.
• If access to the operator and administrator levels of the Parameter Setting menu is not protected
by passcodes, faulty operation may occur.

2.1 Design and Function
• The 1- and 2-channel transmitter permits a free combination of the pH/ORP process variables, con-
ductivity (2-/4-electrode sensors, toroidal sensors), and oxygen, and can, for example, simultane-
ously measure pH values and conductivity.
• The TFT color display provides clear information on operating states and errors during parameter
setting or measurement in accordance with NAMUR recommendations.
• The user interface is multi-lingual with full-text menu navigation.

Operation with Analog Sensors
To enable operation with analog sensors, analog measuring modules are plugged in and must be con-
figured during initial start-up.
Operation with Optical Sensors
The SE740 digital optical sensor for dissolved oxygen can be directly connected to Stratos Multi.
Parameter Sets
Two complete parameter sets (A, B) can be stored in the device. The control element for switching
between the parameter sets (optocoupler input OK1, softkey) is selected in the system control.
The currently activated set can be signaled by a relay contact.
Power Supply
Current is provided through a universal mains supply 80...230VAC, 45... 65Hz/24...60VDC.
