Cleanfit CPA871 Basic safety instructions

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 Cleanfit CPA871 retractable assembly, which can be manually or pneumatically operated, is designed for the installation of sensors in vessels and pipes.

Thanks to its design, it can be operated in pressurized systems (→  59).

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.

2.2.1 Use in explosion-proof areas

As a manufacturer of products used for analysis, we declare that the product supplied has undergone an ignition risk assessment and may be used in hazardous atmospheres once the following conditions for safe usage have been met:

• The protective ring is labeled as follows: "CAUTION, DANGER DUE TO ELECTROSTATIC CHARGES, CLEAN USING ONLY AN ANTISTATIC CLOTH". This instruction must be observed.

• Assemblies comprising wetted parts made of non-conductive material, must not be used in potentially explosive atmospheres.

• The compressed air supply, sensors and limit position switches must comply with the applicable guidelines and standards for use in hazardous atmospheres, be labeled with the degree of protection and meet the requirements of the relevant range of application. The ambient temperatures must be observed. The limit position switch used in the product complies with this requirement.

• Ensure that the compressed air does not contain a potentially explosive atmosphere.

• Care must be taken to ensure that movements during insertion and retraction of the sensor do not damage the connection.

• The product must be incorporated into the local potential equalization system.

• The Operating Instructions for the product and in particular the conditions for safe usage must be read, understood and implemented.

The product does not need to be labeled with the degree of protection.

2.3 Occupational safety

As the user, you are responsible for complying with the following safety conditions:

• Installation guidelines

• Local standards and regulations

Basic safety instructions Cleanfit CPA871

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.

2.5 Product safety

2.5.1 State of the art

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 European standards have been observed.

Installation recommendation

The two O-rings of the process seal close off the process in the relevant limit position. The assembly is open to the process during insertion/retraction; the rinse connections must either be pipe-fitted or sealed.

The connection between the service chamber and the process is open during movement; the sealing water function can be used as a result. The rinse chamber outlet must be blocked (e.g., with a shutoff valve) to implement the sealing water

Installing/removing the assembly from the process

WARNING

Risk of injury from high pressure, high temperature or chemical hazards if process medium escapes.

Wear protective gloves, protective goggles and protective clothing.

‣

Mount the assembly only if vessels or pipes are empty and unpressurized.

‣

Prior to installation, check the flange seal between the flanges.

1. Move the assembly to the service position.  (The triangle position marking is visible (→  14).

2. Secure the assembly on the tank or piping via the process connection.

3. Follow the instructions in the next section to connect pipes for compressed air and rinse water (for the relevant assembly version).

Pneumatic connection for automatic operation

Prerequisites:

• Air pressure 4 to 7 bar (absolute pressure) (58 to 102 psi)

• Compressed air quality in accordance with ISO 8573-1:2001 Quality class 3.3.3 or 3.4.3

• Solids class 3 (max. 5 μm, max. 5 mg/m3, contamination with particles)

• Water content for temperatures ≥ 15 °C: Class 4 pressure condensation point 3 °C or lower

• Water content for temperatures of 5 to 15 °C: Class 3 pressure condensation point -20 °C or lower

• Oil content: Class 3 (max. 1 mg/m3)

• Air temperature: 5 °C or higher

• No continuous air consumption

• Minimum nominal diameter of air pipes: 2 mm (0.08 ")

A dual-operating cylinder is used to operate the pneumatic drive.

An automatic limit position lock both in service and measuring position secures the assembly to prevent it from moving inadvertently in the event of a failure in the control air. The assembly remains in the relevant position.

Connection: Push connector M5, hose 4/2 mm OD/ID (adapter for 6/4 mm OD/ID enclosed)

NOTICE
