1. Functional Safety

1.1 Scope

This safety manual applies to measuring systems consisting of Klay Instruments pressure transmitter

in a two wire 4-20 mA loop.

This functionally safety manual applies for:

Series 2000, 2000-SAN, CER-2000, 2000-SAN Cable, 2000-Hydrobar Cable and Hydrobar-I-Cable

The series 2000 with a serial number of the transmitter > 4309036

The Hydrobar-I with a serial number of the transmitter > 7309014

Software from Rev. V9.17

1.2 Application area

The measuring system can be used for process pressure or level measurement of gases, vapours and

liquids which meet the specific requirements of the safety technology.

1.3 Safety function

The device generates an analogue output signal of 4-20 mA that is proportional to the current pressure.

This is controlled by a micro processing unit and has to be distinguished between 4-20 mA. The fault

current is ≤3.9 mA or > 20.8 mA. Observe with the conception of the system, that the technical data of the

product-specific as well as Functional Safety Data Sheet may not be exceeded. Especially the permissible

operating condition (permissible temperatures, etc.) have to be ensured.

Make sure that the entire interconnection of different components fulfills the requirements

of the application. The operator is responsible for correct construction of the overall system.

After installation a validation of the safety function is required.

The damping of the output signal must be adapted to the process safety time.

The operability of the measuring device should be checked via proof test in regularly intervals. For

defining the scope and interval of tests, the following table can be used as a reference. However

each application has its own unique properties and exceptions. Klay Instruments is not an expert

in the customers process (technical field) and does not accept liability for consequential damage

of any kind due to use or misuse of the Series 2000 and Hydrobar I.

The installation, maintenance and cleaning of the devices must be performed exclusively by

persons specifically trained and authorized for this purpose as far as they are familiar with

the devices!

Modifications on devices and connections void Functional Safety and the warranty!

It is the responsibility of the user to verify whether the chosen version of the device is

suitable for the intended application and the existing environmental conditions. Klay

Instruments does not assume any liability for an incorrect selection and its consequences.

2. Compliance

2.1 Assumptions

Failure rates are constant, wear of the mechanical parts is not taken into account.

The average ambient temperature during the operating time is 20°C - 40 °C (68 °C - 104 °F).

The environmental conditions correspond to an industrial environment.

The lifetime of the components is around 10 to 14 years (IEC 61508-2, 7.4.7.4, remark 3).

2.2 Product identification

Make sure the device has been ordered with SIL-conformity and has been delivered conformably.

The transmitter is clearly marked with a special SIL marking on the enclosure.

2.3 SIL conformity

The SIL conformity is confirmed by the verification documents in the appendix.

3.2 Service Proven

According to IEC 61511-1, paragraph 11.4.4, the failure tolerance HFT can be reduced by one for

service-proven subsystems if the following conditions are met:

The hardware of the device is selected on the basis of prior use (see IEC 61511-1 Cl. 11.5.3)

The device allows adjustment of process-related parameters only, for example, measuring

range, upscale or downscale failure direction.

The adjustment of the process-related parameters of the device is protected.

The function has a SIL requirement of less than 4.

Special requirements apply (see IEC 61508)

The user must have experience with process, and must be in compliance by the requirements of IEC

61511-1 clause 11.5.3. The operating experience must be recorded in the user’s list of equipment

approved for use in their facilities.

4. Safety-related characteristics

4.1 Basics

The failure rates of the electronics, the mechanical parts of the transmitter as well as the process fitting

are determined by an FMEDA according to IEC 61508. The calculations are based on component failure

rates according to SN 29500. All values refer to an average ambient temperature during the operating

time of 55 °C (104 °F). For a higher average temperature of 60 °C (140 °F), the failure rates should be

multiplied by a factor of 2.5. A similar factor applies if frequent temperature fluctuations are expected.

4.2 Safe function

A measurement of absolute and relative pressure or level within the specified safety

accuracy of 0.1 % from full span.

The safety function response time is 100ms.

4.4 Time-dependent process of PFDavg

The chronological sequence of PFDavg is nearly linear to the operating time over a period up to 10

years. The above values apply only to the TProof interval after which a recurring function test must

be carried out

4.5 Service life

After 10 to 14 years, the failure rates of the electronic components will increase, whereby the

derived PFD values will deteriorate (IEC 61508-2, 7.4.7.4, note 3).
