Safety instructions and measures

1 Safety instructions and measures
The SAMSON TROVIS 5724-8 and TROVIS 5725-8 Electric Actuators with Process Control-
ler are a combination of an electric actuator and an integrated digital controller with two PID
control modules. They are designed for operating a mounted globe valve. In combination
with the valve, the actuator is used to control the flow of liquids or vapors in the pipeline. The
electric actuators with process controller are suitable for closed-loop operation in heating
and cooling applications.
The actuator is designed to operate under exactly defined conditions (e.g. thrust, travel).
Therefore, operators must ensure that the actuator is only used in operating conditions that
meet the specifications used for sizing the actuator at the ordering stage. In case operators
intend to use the actuator in other applications or conditions than specified, contact SAM-
SON.
SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice 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. See
section 3.6.
Reasonably foreseeable misuse
The actuator 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 service and repair work not described
Qualifications of operating personnel
The actuator must be mounted, started up, serviced and repaired by fully trained and quali-
fied personnel only; the accepted industry codes and practices must 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 spe-
cialized training, their knowledge and experience as well as their knowledge of the applica-
ble standards.
