Section 1: Functional Specification SIL Safety Manual April 2017 DOC.SILM.EEP.EN Rev. 0 Section 1: Functional Specification The safety function for EL-O-Matic E and P Series pneumatic actuator is defined as follows: Double-Acting Scenario: When an unsafe condition is detected in a plant by a process sensor, the controller, via actuator control system, drives the Actuator to close the shut-down valve, depressurizing (if under pressure) the Opening side of the actuator and pressurizing the Closing side of the actuator.
Section 2: Configuration of the Product SIL Safety Manual DOC.SILM.EEP.EN Rev. 0 April 2017 Section 2: Configuration of the Product The EL-O-Matic E and P Series are pneumatically operated actuators designed to operate Ball / Plug / Butterfly valves, automation of louvers and dampers & automation of any quarter-turn mechanism.
Section 3: Service Condition Limitations (Limitation of Use) SIL Safety Manual April 2017 DOC.SILM.EEP.EN Rev. 0 Section 3: Service Condition Limitations (Limitation of Use) The operating capabilities are listed below: • Maximum Operating Pressure: — Pneumatic Service — Up to 8 Barg (116 PSIg) •...
Section 4: Expected Lifetime SIL Safety Manual April 2017 DOC.SILM.EEP.EN Rev. 0 Section 4: Expected Lifetime Actuator lifetime (for which failure rates indicated in Par. 5 are ensured) strongly depends on operating conditions. For normal service conditions, EL-O-Matic E and P Series actuators can be in good conditions also after more than 10 years with planned minimum maintenance.
Section 6: Installation and Site Acceptance Procedure SIL Safety Manual April 2017 DOC.SILM.EEP.EN Rev. 0 Section 6: Installation and Site Acceptance Procedure Any necessary installation and site acceptance procedures are discussed in the EL-O-Matic E and P Series actuators Installation, Operation and Maintenance manual. The Installation, Operation and Maintenance manual defines exercising of the actuator after installation and defines testing after maintenance.
Section 7: Periodic Test and Maintenance Requirements SIL Safety Manual DOC.SILM.EEP.EN Rev. 0 April 2017 Section 7: Periodic Test and Maintenance Requirements 7�1 General Please consider that the information in this paragraph are relevant only in regards of Reliability Tests; please refer to Doc. Installation, Operation and Maintenance manual for detailed information about product maintenance, handling and storage.
SIL Safety Manual Section 7: Periodic Test and Maintenance Requirements April 2017 DOC.SILM.EEP.EN Rev. 0 7�3 Partial-Stroke Test The “Partial-Stroke Test” (“On-line”) can be performed to improve the PFD value. A typical partial-stroke value is 15% of the stroke. The “Partial-Stroke Test” (“On line”) can be performed to satisfy PFD (average probability of failure on demand) value.
SIL Safety Manual Section 8: Hardware Fault Tolerance DOC.SILM.EEP.EN Rev. 0 April 2017 Section 8: Hardware Fault Tolerance The HFT of the device is 0. The requirements of minimum hardware fault tolerance (HFT) according to Tab.6 of IEC 61511-1 have to be observed but, as long as has been performed an assessment report fully in compliance with IEC 61508 part 1 to7, alternative fault tolerance requirements have to be considered applicable according to Table 2 of IEC 61508-2 as per par.
SIL Safety Manual Section 9: Classification April 2017 DOC.SILM.EEP.EN Rev. 0 Section 9: Classification The equipment is classified Type A according to IEC 61508-2. Classification...
Section 10: Safe Failure Fraction SIL Safety Manual DOC.SILM.EEP.EN Rev. 0 April 2017 Section 10: Safe Failure Fraction SFF=0 without external diagnostic tests. SFF>0 with external diagnostic tests, carried out according to definition 3.8.7 of IEC 61508-4. • SFF = 91% with Partial-Stroke Test. •...
Section 11: Mean Repair Time SIL Safety Manual April 2017 DOC.SILM.EEP.EN Rev. 0 Section 11: Mean Repair Time For sizes E12 to size E600 the MRT of the device is 1 hour. For sizes E950 E1600, P2500 and P4000 the MRT of the device is 2 hours. NOTICE The MRT is estimated considering availability of skilled personnel for maintenance, spare parts and adequate tools and materials on site (that is, it encompasses the effective time to...
