Chapter 1 - General information
MAN 714 TPS Series – Use and maintenance manual – Rev. 03 1.3
1.6 Misuses
Any use of the actuator not described in this manual must be regarded as “not intended” by the Manufacturer.
When installed in the plant together with all the accessories specified in the order acknowledgement, the
actuator cannot be operated if the guards provided by the Manufacturer are not fixed in place, and/or if the
safety equipment is not assembled, not connected, not adjusted, deliberately excluded or in any way
ineffective.
1.7 Limitation of use
Please refer to the environmental conditions where the actuator is employed. In addition to the information
given in section 2.12 - Technical data, the provisions listed below must also be observed:
 ATMOSPHERE AT RISK OF FIRE
It is FORBIDDEN to use TPS series actuators in environments at risk of fire and not equipped
with suitable systems for the prevention and extinguishing of fires.
INFORMATION:
The TPS Series pneumatic actuators can be installed in areas at risk of fire exclusively if
they are suitably protected (for example, by means of flameproof covering or of materials
with specific fire resisting characteristics).
Please refer to the documentation relating to the order confirmation for the installation
instructions concerning this problem.
 EXPLOSIVE ATMOSPHERE
It is FORBIDDEN to use TPS series actuators beyond the limits indicated on the rating plate
as regards ATEX certification.
INFORMATION:
TP series pneumatic actuators can be used in explosive atmosphere with the following
classification of zones: zone 1/21
 ENVIRONMENTAL PRESSURE
It is FORBIDDEN to use TPS series actuators in “underwater” environments.
INFORMATION:
TPS series actuators comply with standard EN 60529:1991 + A1:2000 with reference to
IP66M and IP67M degrees of protection. Consistently with the test conditions provided by
the Standard, TPS series actuators can be installed partially or totally immersed, but
cannot be installed in underwater environments where the actuator can be externally
exposed to the action of hydrostatic pressure.
 CORROSIVE ATMOSPHERE
It is FORBIDDEN to use TPS series actuators in environments containing acids, except
for the information below.
INFORMATION:
The quality of the products used and the varnishing method offer a C5I/C5M protection
classification, pursuant to Standard UNI EN ISO 12944, in that way making the actuator
suitable for industrial/maritime/off-shore applications.

2 TECHNICAL DESCRIPTION
2.1 Fields of application
The subject matter of the present manual are the single acting actuators of the Turn Pneumatic (TPS) series
and their various configurations.
The present manual applies ONLY to the actuator intended as a mechanical device that delivers an operating
torque for the 90° rotation of a quarter turn valve, which is moved by a pneumatic cylinder or by the elastic
energy of the spring.
The present manual DOES NOT apply to any accessories installed on the actuator, for which you have to refer
to the relevant annexed documentation specified on the order acknowledgement (of which this manual is an
integral part).
2.2 Identification data of the actuator
The main identification data of the order acknowledgement are featured on the plate affixed to the actuator
