1.3 Documentation

The following manuals which complement these Operating Instructions can be found on

the product pages on the Internet:

• Technical Information of the sensor

• Operating Instructions for the transmitter used

Memosens CFS51 Basic safety instructions

Endress+Hauser 5

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 Intended use

The sensor is used to measure polycyclic aromatic hydrocarbons PAHs (PAH) using

fluorescence measurement.

The device is suitable for the following field of application:

Monitoring of scrubber washwater on ships

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

LWARNING

UV radiation from this product

Can cause damage to the eyes and skin!

‣Avoid any exposure of the eyes and skin to the unshielded product.

‣When the sensor is switched on, avoid looking directly into the sensor window without

appropriate eye protection. The exposure limits according to IEC 62471:2008 are not

exceeded within the first 100 seconds.

‣Appropriate protective goggles must be worn to protect against UV radiation.

‣Cover the light source when performing maintenance tasks that do not need UV light.

• The risk to the observer depends on how the user installs and uses the sensor.

• The sensor's lamp radiates light in the 254 nm wavelength range (UV radiation). The

sensor's lamp is categorized as Risk Group 3 according to EN/IEC 62471.

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.

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 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.

Memosens CFS51 Product description

3 Product description

3.1 Product design

The device can be operated directly in the process, without any additional sampling (in-

line).

The device consists of the following assemblies:

• Power supply

• Light source

• Detectors

Detectors detect the measuring signals, digitize them and process them to form a

measured value.

• Sensor microcontroller

This is responsible for controlling internal processes and transmitting data.

All the data - including the calibration data - are stored in the device. The device can be

used at a measuring point and is either precalibrated or externally calibrated. The device

can also be used for several measuring points with different calibrations.

3.1.1 Measuring principle

Fluorescence measurement is used to demonstrate the presence of polycyclic aromatic

hydrocarbons PAHs (PAH) in water. The device stimulates the PAHs with UV light and

detects the fluorescent radiation emitted by the PAHs as a result. The PAH concentration

is measured in units of phenanthrene equivalents (PAHphe) according to MEPC.259(68)

and MEPC.340(77) 1). The measurement is performed in the excitation wavelength range

of 254 nm and in the reception wavelength range up to 360 nm.
