Functional Specification
Section 1: Functional Specication
The safety function for EL-O-Matic E and P Series pneumatic actuator is dened as follows:
Double-Acting Scenario:
a. 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.
b. When an unsafe condition is detected in a plant by a process sensor, the
controller, via actuator control system drives the Actuator to open the
blow-down valve, depressurizing (if under pressure ) the Closing side
of the pneumatic actuator and pressurizing the Opening side of the
pneumatic actuator.
Single-Acting Scenario:
a. When an unsafe condition is detected in a plant by a process sensor, the
controller, via actuator control system drives the Actuator to rotate with
sufcient torque to move a valve to its fail-safe state when hold-position
air pressure is released.
The EL-O-Matic E and P Series brand Actuator Selection Procedure provides functional
denition with specics on input variables and performance.
In any case, the choice of the safety function to be implemented is responsibility of the
system integrator.

Section 1: Functional Specification

Configuration of the Product
Section 2: Conguration of the Product
The EL-O-Matic E and P Series are pneumatically operated actuators designed to operate
Ball / Plug / Buttery valves, automation of louvers and dampers & automation of any
quarter-turn mechanism. Both the double-acting and single-acting (spring-return) versions
of the EL-O-Matic E and P Series pneumatic actuators are designed in such a way that there
are no moving parts on the outside (with the exception of the position indicator). This
makes them safe, easy to install and virtually maintenance free.
For further details about actuator congurations, please refer to the EL-O-Matic E and
P Series product data sheets, Quick Reference Guide and Installation, Operation and
Maintenance manual.

Service Condition Limitations (Limitation of Use)
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)
• Ambient Temperature:
Temperature extremes require different solutions to maintain actuator operational
integrity and reliability. For each EL-O-Matic E and P Series actuator is available in
three different temperature executions.
— -20°C to +80°C (-4°F to +176°F) Standard temperature
— -20°C to +120°C (-4°F to +248°F) High Temperature
— -40°C to +80°C (-40°F to +176°F) Low Temperature
• Torque Output Range:
— Double-Acting EL-O-Matic E and P Series actuators, requiring pressure to
rotate in either direction, are available with a torque range between 4.8
Nm (42 lbf.in) and 6,619 Nm (58,583 lbf.in)
— The EL-O-Matic E and P Series spring-return models require pressure in
only one direction of travel and are suitable for air-fail close and air-fail to
open applications without modication. These models are available with a
spring end torque between 4.6 Nm (41 lbf.in) and 1958 Nm (17,330 lbf.in)
• Safety Function:
For spring-return models, the safety function is self-evident performed by the
springs. The safety function of double-acting models shall be performed by the
A-port. The failure rates in Section 5 are valid only for this conguration.
NOTE:
This product is only intended for use in large-scale xed installations excluded from the
scope of Directive 2011/65/EU on the restriction of the use of certain hazardous substances
in electrical and electronic equipment (RoHS 2).

Expected Lifetime
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. Normal
working life is the number of cycles as dened in Table 1 of EN 15714-3.
EL-O-Matic E and P Series carry a warranty period of:
• 18 months after delivery if properly stored in conditions that we declare or
• 12 months after installation on site.
