Liquiline System CA80NO Basic safety instructions
Endress+Hauser 7
2 Basic safety instructions
2.1 Requirements for the 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
The Liquiline System CA80NO is a wet-chemical analyzer for the almost continuous
determination of the concentration of nitrite in liquid media.
The analyzer is designed for use in the following applications:
• Monitoring of drinking water treatment and distribution
• Monitoring of the wastewater treatment plant outlet
• Quality control of raw water for the food industry
• Monitoring of drinking water
• Control of industrial wastewater treatment
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.
2.3 Workplace safety
As the user, you are responsible for complying with the following safety conditions:
• Installation guidelines
• Local standards and regulations
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.

Basic safety instructions Liquiline System CA80NO
8 Endress+Hauser
During operation:
1. If faults cannot be rectified:
products must be taken out of service and protected against unintentional operation.
2. Keep the door closed when not carrying out service and maintenance work.
LCAUTION
Activities while the analyzer is in operation
Risk of injury and infection from medium!
‣Before you release any hoses, make sure that no actions, such as the pumping of
sample, are currently running or are due to start shortly.
‣Wear protective clothing, goggles and gloves or take other suitable measures to protect
yourself.
‣Wipe up any spilt reagent with a disposable tissue and rinse with clear water. Then dry
the cleaned areas with a cloth.
LCAUTION
Risk of injury from door stop mechanism
‣Always open the door fully to ensure the door stop engages properly.
2.5 Product safety
2.5.1 State-of-the-art technology
The product 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 relevant regulations and
international standards have been observed.
Devices connected to the analyzer must comply with the applicable safety standards.
2.5.2 IT security
We only provide a warranty if the device is installed and used as described in the
Operating Instructions. The device is equipped with security mechanisms to protect it
against any inadvertent changes to the device settings.
IT security measures in line with operators' security standards and designed to provide
additional protection for the device and device data transfer must be implemented by the
operators themselves.
