2 Basic safety instructions
2.1 Requirements for personnel
‣Installation, commissioning, operation and maintenance of the measuring system must only
be carried out by trained technical personnel.
‣The technical personnel must be authorized to perform the tasks by the owner-operator.
‣The electrical connection may only be established by an electrical technician.
‣The technical personnel must have read and understood these Operating Instructions and
must follow the instructions they contain.
‣Faults at the measuring point may only be rectified by authorized and properly trained
personnel.
Repairs not described in the enclosed Operating Instructions may only be carried out
directly at the manufacturer's or by the Service Organization.
2.2 Designated use
2.2.1 Non-hazardous atmosphere
Liquiline CM44xR is a multichannel controller for connecting digital sensors with Memosens
technology in non-hazardous locations.
The device is designed for use in the following applications:
• Food and beverages
•Lifescience
• Water and wastewater
• Chemical industry
2.2.2 Non-designated use and misuse
NOTICE
Objects placed on the housing
Can cause short-circuits or fire. Failure of individual cabinet components or the entire
measuring point possible.
‣Never place any objects, such as tools, cables, paper, food, liquid containers or similar, on the
housing.
‣Always comply with the specifications of the provider as regards fire safety (smoking) and
the handling of foodstuffs (beverages).
If the device is used for any purpose other than that described, this poses a threat to the safety
of people and the entire measuring system and is thus not permitted.
The manufacturer does not accept liability for damage caused by improper or non-designated
use.

2.2.3 Installation environment
The device and associated power units can be operated with 24 V AC, 24 V DC or 100 to 230 V
AC and provide shock protection as per the IP20 rating. The components have been designed for
Pollution Degree 2. Condensation should not form on the components. For this reason the
components must be installed in a way that they are protected by an appropriate protective
enclosure. Compliance with the ambient conditions specified in the manual is mandatory.
2.3 Occupational safety
As the user, you are responsible for observing the following safety regulations:
• Installation guidelines
• Local standards and regulations
Electromagnetic compatibility
This device has been tested for electromagnetic compatibility in accordance with the applicable
European standards for industrial applications.
The electromagnetic compatibility indicated only applies to a device that has been connected in
accordance with the instructions in
these Operating Instructions.
2.4 Operational safety
‣Prior to commissioning the entire measuring point, check that all connections are correct.
Make sure that electric cables and hose connections are not damaged.
‣Do not commission damaged products. Protect them against unintentional startup. Label
and identify the damaged product as defective.
‣If the faults cannot be eliminated, take the products out of service and protect them against
unintentional startup.
CAUTION
!
The cleaning system is not switched off during calibration or maintenance activities
Risk of injury due to medium or cleaning agent
‣If a cleaning system is connected, switch it off before removing a sensor from the medium.
‣If you are not switching off the cleaning system because you wish to test the cleaning
function, wear protective clothing, goggles and gloves or take other appropriate measures.
2.5 Product safety
The transmitter is designed to meet state-of-the-art safety requirements, has been tested and
left the factory in a condition in which it is safe to operate.
The applicable regulations and European standards have been taken into account.

Fig. 3: Slot and port assignment on the display
• Inputs are assigned to measuring channels in the
ascending order of the slots and ports.
Adjacent example:
"CH1: 1:1 pH glass" means:
Channel 1 (CH1) is slot 1 (basic module) : Port 1
(input 1), pH glass sensor
• The outputs and relays are named after their
function, e.g. "Current output", and are displayed in
ascending order with the slot and port numbers
