Safety instructions and measures

1 Safety instructions and measures
Intended use
The Type 3710 Reversing Amplifier is mounted on pneumatic control valves to allow double-acting pneumatic actuators to be operated using single-acting electropneumatic positioners (SAMSON Types 3725, 3730-x, 3731-x, 3766 and TROVIS 3730-x Positioners) or limit
switches (SAMSON Type 3767 Limit Switch). The device is designed to operate under exactly
defined conditions (e.g. operating pressure, temperature). Therefore, operators must ensurethat the reversing amplifier is only used in applications where the operating conditions correspond to the technical data. In case operators intend to use the positioner in other applications or conditions than specified, contact SAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the device for its intended purpose or for damage caused by external forces or any other external
factors.
Î Refer to the technical data for limits and fields of application as well as possible uses.
Reasonably foreseeable misuse
The Type 3710 Reversing Amplifier is not suitable for the following applications:− Use outside the limits defined during sizing and by the technical data
Furthermore, the following activities do not comply with the intended use:
− Use of non-original spare parts− Performing maintenance activities not described in these instructions
Qualifications of operating personnel
The reversing amplifier must be mounted, started up and serviced by fully trained and qualified personnel only; the accepted industry codes and practices are to be observed. According to these mounting and operating instructions, trained personnel refers to individuals who
are able to judge the work they are assigned to and recognize possible hazards due to their
specialized training, their knowledge and experience as well as their knowledge of the applicable standards.
Devices operated together with explosion-protected positioners/limit switches must only behandled by personnel who has undergone special training or instructions or who is authorized to work on explosion-protected devices in hazardous areas.

Safety instructions and measures

Personal protective equipment
No personal protective equipment is required for the direct handling of the reversing amplifier. Work on the control valve may be necessary when mounting or removing the device.
Î Observe the requirements for personal protective equipment specified in the valve documentation.
Î Check with the plant operator for details on further protective equipment.
Revisions and other modifications
Revisions, conversions or other modifications of the product are not authorized by SAMSON.
They are performed at the user's own risk and may lead to safety hazards, for example. Furthermore, the product may no longer meet the requirements for its intended use.
Warning against residual hazards
To avoid personal injury or property damage, plant operators and operating personnel must
prevent hazards that could be caused in the control valve by the process medium, the operating pressure, the signal pressure or by moving parts by taking appropriate precautions. Plant
operators and operating personnel must observe all hazard statements, warning and caution
notes in these mounting and operating instructions, especially for installation, start-up andservice work.
If inadmissible motions or forces are produced in the pneumatic actuator as a result of the
supply pressure, it must be restricted using a suitable supply pressure reducing station.
Responsibilities of the operator
Operators are responsible for proper use and compliance with the safety regulations. Operators are obliged to provide these mounting and operating instructions to the operating personnel and to instruct them in proper operation. Furthermore, operators must ensure that operating personnel or third parties are not exposed to any danger.
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions aswell as the specified hazard statements, warning and caution notes. Furthermore, the operating personnel must be familiar with the applicable health, safety and accident prevention
regulations and comply with them.

Design and principle of operation

3 Design and principle of operation
The reversing amplifier allows double-acting
pneumatic actuators to be operated using
single-acting positioners or limit switches.
The positioner creates an output signal pressure Y1, to which the air pressure Y2 is added. The reversing amplifier uses the supply
pressure Z as auxiliary power.

Positioner

The following rule applies:
Y1 + Y2 = Z
Example:Y1 of the positioner
