1 Safety instructions and measures
Intended use
The TROVIS 5724-3 and TROVIS 5725-3 Electric Actuators with Process Controller are elec-
tric actuators with an integrated digital controller. They are designed for operating a mount-
ed globe valve. In combination with the valve, the electric actuators with process controller
are used to control the flow of liquids in the pipeline. The electric actuators with process con-
troller are suitable for closed-loop operation in DHW applications.
The actuators are designed to operate under exactly defined conditions (e.g. thrust, travel).
Therefore, operators must ensure that the actuators are only used in operating conditions that
meet the specifications used for sizing the actuator at the ordering stage. In case operators
intend to use an actuator in other applications or conditions than specified, contact
SAMSON.
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
the 'Design and principle of operation' section.
Reasonably foreseeable misuse
The electric actuators with process controller are 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 electric actuators with process controller must be mounted, started up, serviced and re-
paired by fully trained and qualified personnel only; the accepted industry codes and prac-
tices 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 rec-
ognize possible hazards due to their specialized training, their knowledge and experience as
well as their knowledge of the applicable standards.
