Liquiline CM44P Basic safety instructions
Endress+Hauser 7
2 Basic safety instructions
2.1 Requirements for personnel
• Installation, commissioning, operation and maintenance of the measuring system may
be carried out only by specially trained technical personnel.
• The technical personnel must be authorized by the plant operator to carry out the
specified activities.
• The electrical connection may be performed only by an electrical technician.
• The technical personnel must have read and understood these Operating Instructions
and must follow the instructions contained therein.
• Faults at the measuring point may only be rectified by authorized and specially trained
personnel.
Repairs not described in the Operating Instructions provided must be carried out only
directly at the manufacturer's site or by the service organization.
2.2 Designated use
2.2.1 Non-hazardous atmosphere
Liquiline CM44P is a multichannel controller for connecting analog photometers and
digital sensors with Memosens technology in non-hazardous environments.
The device is designed for use in the following applications:
• Food and beverages
• Life science
• Power stations
• Chemical industry
• Other industrial applications
2.2.2 Hazardous environment in accordance with cCSAus Class I Div.
2
‣Please pay attention to the control drawing and specified operating conditions in the
appendix of this manual and follow the instructions.
2.2.3 Non-designated use and improper use
NOTICE
Objects stored on top of the housing
May cause short-circuits or fire or result in the failure of individual cabinet components or
complete failure of the measuring point!
‣Never place any objects, such as tools, cables, paper, food, liquid containers or similar,
on top of the housing.
‣Always observe the operator's regulations, in particular with regard to fire safety
(smoking) and foodstuffs (beverages).
Use of the device for any purpose other than that described, poses a threat to the safety of
people and of the entire measuring system and is therefore not permitted.
The manufacturer is not liable for damage caused by improper or non-designated use.

Basic safety instructions Liquiline CM44P
8 Endress+Hauser
2.2.4 Installation environment (cabinet device only)
The device and the associated power units can be operated with 24 V AC, 24 V DC or 100
to 230 V AC and provide shock protection in accordance with IP20.
The components have been designed for pollution degree 2, and moisture must not be
allowed to collect in them. The components must therefore be installed in an appropriate
enclosure for protection. The ambient conditions specified in the instructions must be
observed here.
2.3 Workplace safety
As the user, you are responsible for complying with the following safety conditions:
• Installation guidelines
• Local standards and regulations
• Regulations for explosion protection
Electromagnetic compatibility
• The product has been tested for electromagnetic compatibility in accordance with the
applicable international standards for industrial applications.
• The electromagnetic compatibility indicated applies only to a product that has been
connected in accordance with these Operating Instructions.
2.4 Operational safety
Before commissioning the entire measuring point:
1. Verify that all connections are correct.
2. Ensure that electrical cables and hose connections are undamaged.
3. Do not operate damaged products, and protect them against unintentional operation.
4. Label damaged products as defective.
During operation:
‣If faults cannot be rectified:
products must be taken out of service and protected against unintentional operation.
LCAUTION
Cleaning 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 wish to check the cleaning function and have therefore not switched off the
cleaning system, wear protective clothing, goggles and gloves or take other appropriate
measures.

1) Example: you want to loop the signal from the alarm relay to a siren and a lamp. The terminals on the
alarm relay only accommodate one cable. Route the signal from the alarm relay to a terminal on the
distributor block. The block's terminals are all interconnected. You therefore have 3 additional terminals on
this block from where you can carry the signal forward to the consumer (siren, lamp etc.). The signal can
be multiplied in this way.

Adjacent example:
"CH1: 1:1 pH glass" means:
Channel 1 (CH1) is slot 1 (basic module) : Port 1 (input
1), pH glass sensor
• Outputs and relays are named according to their

LCAUTION
Impermissible collection of moisture in the device
Puts the safety of the user at risk!
‣The device has IP20 shock protection. Never allow moisture to collect in the device.
‣Comply with the specified ambient conditions,e.g. by installing the device in an
appropriate protective enclosure.
NOTICE
Incorrect mounting location in the cabinet, spacing regulations not observed
Possible malfunctions as a result of heat buildup and interference from neighboring
devices!
‣Do not position the device directly above sources of heat. The temperature specification
must be observed.
‣The components are designed for convection-based cooling. Avoid heat buildup. Ensure
openings are not covered, e.g. by cables.
‣Observe the specified distances to other devices.
‣Physically separate the device from frequency converters and high-voltage devices.
‣Recommended installation direction: horizontal. The specified ambient conditions, and
particularly the ambient temperatures, only apply for horizontal installation.
‣Vertical orientation is also possible. However, this requires additional fixing clips at the
place of installation to hold the device in position on the DIN rail.
‣Recommended installation of power unit: to the left of the device.
The following minimum clearance specifications must be observed:
• Distances at the side in relation to other devices incl. power units and to the wall of the
cabinet:
at least 20 mm (0.79 inch)
• Distance above and below the device and depth distance (to control cabinet door or other
